Yes, dark foods such as blueberries, black licorice, beets, dark leafy greens, and supplements containing iron or bismuth can temporarily turn stool very dark or black, and the color typically returns to normal within one to two days once the food is out of your system. However, black stool that looks tarry, sticky, or smells unusually foul may signal bleeding in the upper digestive tract rather than something you ate, and there are several important distinctions and warning signs to consider below. Timing, texture, smell, and accompanying symptoms like dizziness, stomach pain, vomiting, or fatigue all help separate a harmless dietary cause from one that needs prompt attention, as explained more fully below. Because food-related and bleeding-related black stools can look similar to the untrained eye, guessing can either cause unnecessary worry or delay care that matters. Take a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> to review your specific symptoms, diet, and medications in minutes, get a clearer picture of what may be behind the color change, and understand whether monitoring at home or seeing a clinician is the smarter next step.

Yes, consistently eating too few calories after 65 can put both your heart and bones at risk, and there are several important factors to consider below. Chronic under-eating in older adults can trigger muscle and bone loss, lower bone density, and raise fracture risk, while also depleting protein, calcium, vitamin D, and other nutrients the heart muscle depends on. Severe or rapid calorie restriction has also been linked to electrolyte imbalances, irregular heart rhythms, low blood pressure, fatigue, and a weakened immune response, and unintentional weight loss can signal an underlying medical problem. Warning signs, safe calorie and protein targets, and when to seek medical care are explained in detail below, so the full answer is worth reading before making changes to your diet. If you are worried that low appetite, unplanned weight loss, or new fatigue may be affecting your heart or bones, a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> can help you clarify what your symptoms may mean in minutes, organize them into clear next steps, and decide whether this warrants a conversation with your doctor sooner rather than later.

Yes, in large amounts cloves can pose risks to both your liver and your blood: cloves are rich in eugenol, which has been linked to liver injury and liver failure in cases of concentrated clove oil ingestion, particularly in children, while eugenol also inhibits platelet clumping and may increase bleeding or bruising risk, especially if you take warfarin, aspirin, or other blood thinners, or have surgery scheduled. Normal culinary use in food and tea is generally considered safe for most adults, but dose, form (whole cloves versus clove oil or supplements), existing liver conditions, and medication interactions all change the picture, so see below to understand more about the warning signs and safe limits. Symptoms such as yellowing skin or eyes, dark urine, upper right abdominal pain, unusual bleeding, or persistent nausea after heavy clove use warrant prompt medical attention. If you are unsure whether your symptoms are related to cloves, a supplement, a medication interaction, or something unrelated, a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> can help you sort possible causes in just a few minutes. It asks the same kinds of questions a clinician would, then points you toward the right level of care so you know whether to monitor at home, book an appointment, or seek urgent help now.

Yes, acidic foods like oranges, lemons, tomatoes, and pineapple can trigger canker sores on the tongue in people prone to them, though they usually irritate the tissue or aggravate an existing sore rather than directly causing one. Other common triggers include minor mouth injuries from biting or brushing, stress, hormonal shifts, sodium lauryl sulfate in toothpaste, and low levels of iron, folate, vitamin B12, or zinc. Most canker sores heal on their own within 7 to 14 days, but sores that are unusually large, keep coming back, last longer than three weeks, or come with fever or trouble swallowing deserve medical attention. There are several important distinctions between a harmless acid-triggered sore and something that needs evaluation, so see below to understand more. If a sore on your tongue is making eating or drinking uncomfortable and you are unsure whether the cause is your diet or something else, a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> can help you sort through the possibilities in just a few minutes and clarify whether home care is enough or a clinician should take a look.

Farxiga (dapagliflozin) increases urine output, so it can lead to dehydration, low blood pressure, dizziness, and, in some cases, acute kidney injury, with seniors facing higher risk, particularly those also taking diuretics, ACE inhibitors, ARBs, or NSAIDs, or those who are eating and drinking less during illness. At the same time, this medication is proven to slow long-term kidney decline, and a small early dip in kidney function on lab work is often expected rather than harmful. Warning signs worth urgent attention include lightheadedness on standing, very dark or minimal urine, confusion, rapid weight loss, or swelling paired with fatigue. There are several important distinctions between temporary volume depletion and true kidney failure, along with hydration and sick-day guidance, so see below for the complete answer before making any decisions about your dose. Because dehydration, medication side effects, infection, and kidney problems can produce nearly identical symptoms in older adults, guessing is risky and waiting can allow a reversible issue to become serious. A free, instant, online <a href="https://ubiehealth.com/">symptom check</a> can help you organize what you are feeling, understand which explanations fit best, and decide whether this warrants a same-day call to your prescriber or emergency care.

Flagyl (metronidazole) can cause nerve-related side effects, most notably peripheral neuropathy, which often shows up as numbness, tingling, burning, or weakness in the hands and feet and is most common with high doses or long courses. Less common but serious reactions include seizures, encephalopathy, aseptic meningitis, optic neuritis, severe allergic reactions, C. difficile-associated diarrhea, and a disulfiram-like reaction if alcohol is consumed during or shortly after treatment. Nerve symptoms are frequently reversible once the drug is stopped, but recovery timing, dose thresholds, and warning signs that need urgent care vary by person, so there are several important factors to consider in the complete answer below. Because tingling from a medication can look nearly identical to nerve issues caused by diabetes, B12 deficiency, thyroid disease, or a pinched nerve, sorting out the real driver matters before you stop or continue an antibiotic. Take a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> to see which possible causes best match your symptoms and get clear guidance on whether to call your prescriber now or seek emergency care.

Yes, gallbladder problems such as gallstones, bile duct blockage, inflammation, or life after gallbladder removal can reduce the bile your body needs to digest fat, leading to steatorrhea: pale, greasy, foul-smelling stools that float or stick to the toilet bowl. Other conditions, including pancreatic insufficiency, celiac disease, Crohn's disease, and certain medications, can cause nearly identical stool changes, so there are several factors to consider and important distinctions explained below. Red flags like yellowing skin or eyes, right upper abdominal pain after fatty meals, dark urine, fever, or unexplained weight loss deserve prompt attention, and the details below outline what each pattern may mean. Since ongoing fat malabsorption can quietly lead to vitamin deficiencies, pinpointing the cause early matters more than most people realize. Take a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> to see which conditions best match your symptoms and to understand what steps to take next.

Yes, trapped gas and acid reflux are common, usually harmless causes of pain under the right breast, since the colon's hepatic flexure and the esophagus both sit near this area and can create sharp, burning, or cramping sensations that come and go. Gas pain often shifts with movement or eases after passing gas or a bowel movement, while reflux tends to worsen after large meals, when lying flat, or with a sour taste and burning in the chest. However, several other conditions can mimic these symptoms, including gallbladder problems, muscle strain, rib inflammation, liver issues, and, less often, heart or lung concerns, so the specific pattern of your pain matters. There are important warning signs that should not be ignored, such as pain with fever, jaundice, vomiting, shortness of breath, or pain radiating to your shoulder or back; see below to understand more. Because gas, reflux, and more serious causes can feel remarkably similar, guessing can leave you either needlessly worried or dangerously reassured, which is why a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> is a smart next step to clarify what your specific symptoms suggest and what to do next. Last reviewed for medical accuracy: 09/14/2026

Yes, trapped gas and bloating can trigger cramping or spasm-like sensations under the right rib cage, often because pressure from the colon's hepatic flexure irritates the diaphragm, intercostal muscles, or abdominal wall. These episodes usually shift with position, burping, or passing stool, and may come with fullness, pressure, or a stitch-like twinge that eases within minutes to hours. However, similar right-sided pain can also come from gallstones, liver inflammation, costochondritis, a strained muscle, or referred nerve pain, and there are several important warning signs that separate harmless gas from something more urgent, so see below to understand more. Because gas, muscle, gallbladder, and rib-related causes can feel nearly identical, guessing wrong can mean either needless worry or a missed diagnosis. Take a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> to clarify what your specific pattern of pain most likely points to and what to do next. Last reviewed for medical accuracy: 09/13/2026

Yes, trapped gas and bloating are common causes of pain under the left rib cage, because the splenic flexure of the colon sits directly beneath that area and can stretch or press upward when gas builds up. This discomfort often feels sharp, cramping, or like pressure, and it may shift or ease after passing gas, having a bowel movement, or changing position. Still, other conditions such as acid reflux, costochondritis, muscle strain, constipation, spleen problems, pancreatitis, or heart-related issues can produce similar pain, so the details matter. Warning signs like severe or persistent pain, fever, vomiting, shortness of breath, chest pressure, or pain spreading to the arm, jaw, or back call for urgent care. There are several important factors to consider, including symptom patterns and red flags explained below. Because left-sided rib pain has both harmless and serious explanations, the fastest way to sort out which is more likely for you is to review your specific symptoms rather than guess. A free, instant, online <a href="https://ubiehealth.com/">symptom check</a> asks targeted questions about your pain, digestion, and risk factors, then helps you understand possible causes and whether you should self-manage, see a clinician soon, or seek emergency care. It takes only a few minutes, requires no appointment, and gives you clear language to describe what you are feeling if you do decide to talk with a doctor.

Untreated giardiasis can lead to lasting problems in some people, including malabsorption, lactose intolerance, unintended weight loss, and chronic digestive symptoms that persist even after the parasite clears. In children, prolonged infection may contribute to malnutrition, stunted growth, and developmental delays, while some adults develop post-infectious irritable bowel syndrome or chronic fatigue. True permanent organ damage is uncommon, but the risk of long-term complications rises the longer the infection goes untreated, especially for those with weakened immune systems. Because symptoms can come and go for weeks or months and mimic other gut conditions, timing and testing matter more than most people expect. There are several important factors to consider, including who is most at risk and which lingering symptoms warrant care. See below to understand more. Not sure if what you are experiencing is giardia, another infection, or an unrelated digestive condition? A free, instant, online <a href="https://ubiehealth.com/">symptom check</a> takes just a few minutes, helps you organize what you have been feeling and how long it has lasted, and points you toward the most likely explanations and appropriate next steps. Since early treatment is the best way to prevent lingering complications, getting clarity now can save you weeks of uncertainty and help you have a more focused conversation with a clinician. Last reviewed for medical accuracy: 09/14/2026

Giardia sometimes clears on its own, as mild infections in otherwise healthy people may resolve within two to six weeks, but many cases linger for months and can lead to dehydration, weight loss, temporary lactose intolerance, malabsorption, and ongoing spread to others, so several important factors determine whether waiting it out is safe. Children, pregnant people, travelers, and anyone with a weakened immune system are far less likely to recover without prescription antiparasitic medication, and persistent symptoms can point to a different or additional diagnosis. See below to understand more about how long giardia lasts untreated, which warning signs mean you should be evaluated promptly, and why some infections require testing and treatment. Because watery diarrhea, greasy stools, gas, and fatigue overlap with many other conditions, guessing wrong can mean weeks of unnecessary illness. If you are unsure whether your symptoms fit giardia or something else, a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> can help you organize what you are experiencing and decide whether to schedule stool testing or see a clinician now.

Spending hours in prolonged, high-arousal edging sessions can temporarily blunt your brain's dopamine response, leaving you feeling unmotivated, foggy, restless, or unable to concentrate in class the next day. Lost sleep, skipped meals, and screen overstimulation often do as much damage to focus as the dopamine shift itself, and tolerance can push you toward longer or more extreme content over time. The good news is that these changes are usually reversible, though several factors influence how quickly focus returns, and some concentration problems point to a separate issue like ADHD, depression, or a sleep disorder. See below to understand the details worth considering before you assume this is the only cause. If brain fog, low motivation, or slipping grades are becoming your normal, a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> can help you sort out what is driving it in just a few minutes, privately and without judgment. It reviews your symptoms, flags possible causes you may not have considered, and points you toward the right next step so you are not left guessing. Last reviewed for medical accuracy: 09/14/2026

Hemorrhoids commonly cause bright red rectal bleeding along with anal itching, swelling, and pain during or after bowel movements, but they do not usually cause true abdominal pain, so experiencing both together may signal constipation, an anal fissure, inflammatory bowel disease, diverticular disease, an infection, or another condition that needs evaluation. Cramping, bloating, fever, dark or tarry stools, heavy bleeding, dizziness, or unexplained weight loss are warning signs that deserve prompt medical attention. Several factors influence what your combination of symptoms means, including your age, bowel habits, and how long the bleeding has lasted, so see below to understand more before assuming hemorrhoids are the only explanation. Because bleeding plus abdominal pain can point to causes ranging from harmless to serious, getting clarity quickly matters, and a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> can help you organize what you are feeling into possible explanations in just a few minutes. Use it to understand which symptoms fit hemorrhoids, which do not, and what your most sensible next step should be, whether that is home care or a visit with a clinician.

Yes, persistently elevated nighttime cortisol can contribute to serious health problems, including high blood pressure, insulin resistance, abdominal weight gain, disrupted sleep, and an increased risk of heart disease and stroke over time. Cortisol normally falls at night, so a flattened or reversed rhythm may signal chronic stress, poor sleep, shift work, or an underlying condition such as Cushing's syndrome, sleep apnea, or depression. The degree of risk depends on how high your levels are, how long they stay elevated, and whether other cardiovascular risk factors are present, and there are several important details to consider below. Warning signs that deserve prompt attention include a rapidly rounding face, purple stretch marks, easy bruising, muscle weakness, and blood pressure or blood sugar that is difficult to control. See below for the full explanation of causes, testing options such as late-night salivary cortisol, and when to see a doctor. If you are noticing restless nights, unexplained weight changes, racing heartbeat, or rising blood pressure, guessing is not a great strategy, because these symptoms overlap with many conditions that range from harmless to urgent. A free, instant, online <a href="https://ubiehealth.com/">symptom check</a> takes only a few minutes, asks the same kinds of questions a clinician would, and helps you understand which possibilities fit your situation. It can also help you decide whether to monitor at home, book a routine visit, or seek care sooner, and it gives you clearer language to describe what you are feeling when you do talk to a doctor. Taking a few minutes now can save weeks of uncertainty. Last reviewed for medical accuracy: 09/14/2026

Hydrogen water, meaning plain water infused with molecular hydrogen gas, is generally considered safe for most healthy people, and current research has not shown direct damage to the kidneys or the stomach lining at typical amounts. Mild, temporary effects such as bloating, gas, burping, or loose stools are the most commonly reported issues, often linked to drinking large volumes quickly or to magnesium-based hydrogen tablets. Risks can be higher if you have chronic kidney disease, take diuretics or other medications affecting electrolytes, or use products with added minerals or alkaline agents, so the source and dosage matter as much as the hydrogen itself. Persistent stomach pain, nausea, swelling, changes in urination, or unexplained fatigue are signals that something other than the water may be going on. There are several important factors to weigh before assuming hydrogen water is the cause, and the details below explain what to watch for and when to seek care. If you are noticing digestive discomfort or symptoms that could point to kidney trouble, guessing is the slowest way to get answers. A free, instant, online <a href="https://ubiehealth.com/">symptom check</a> takes only a few minutes, asks the same kinds of questions a clinician would, and helps you see which possible causes fit your situation and how urgent they may be. That clarity makes your next step easier, whether that means adjusting what you drink, scheduling lab work, or talking with a doctor sooner rather than later.

Hydrogen-rich water may modestly reduce markers of inflammation and oxidative stress, and small studies in people with rheumatoid arthritis, osteoarthritis, and exercise-related soreness have reported less pain and stiffness, but the research is early, short-term, and involves very few participants. Results also vary widely because hydrogen gas escapes quickly from water, so dose, container, and freshness all affect what you actually drink. Importantly, hydrogen water is not a proven treatment and should not replace medications, physical therapy, or evaluation of joint pain that is worsening, swollen, warm, or lasting more than a few weeks, since conditions like autoimmune arthritis, gout, and infection need targeted care. There are several important factors and safety considerations to weigh before trying it, including who is most likely to benefit and which symptoms signal something more serious, all explained below. If your joint pain or inflammation keeps returning, guessing at supplements can delay answers, so take a few minutes for a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> to see what may be driving your symptoms and what next step makes the most sense.

Yes, it is possible to have a humerus fracture and not realize it, particularly with hairline stress fractures, small nondisplaced cracks, or pathologic breaks caused by osteoporosis, bone cysts, or cancer, which may feel like a deep ache, bruise, or muscle strain rather than a broken bone. Warning signs that a subtle break is being missed include pain that worsens with lifting or rotating the arm, swelling or bruising near the shoulder or elbow, grinding sensations, weakness, numbness, or tenderness over one specific spot on the upper arm. Age, bone health, nerve damage, and how the injury happened all change how likely it is that a fracture goes unnoticed, and there are several important factors to consider, so see below to understand more. Untreated humerus fractures can heal in a misaligned position, damage the radial nerve, or progress into a complete break, so lingering upper arm pain deserves an X-ray rather than a wait-and-see approach. If you are unsure whether your arm pain is a strain or something more serious, take a few minutes to complete a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> to clarify what your symptoms may point to, what red flags to watch for, and which type of care to seek next.

Drinking alcohol while taking antibiotics is not always dangerous, but with certain drugs, including metronidazole, tinidazole, cefotetan, and griseofulvin, even small amounts can trigger severe reactions such as flushing, vomiting, rapid heartbeat, and pounding headache. Alcohol can also intensify common antibiotic side effects like dizziness, drowsiness, and stomach upset, add strain to the liver, and disrupt the sleep and hydration your body needs to clear an infection. Because the risk depends on your specific antibiotic, dose, liver health, and the infection being treated, the safest choice varies from person to person, and several important details are explained below. If you are unsure whether your symptoms are improving, worsening, or signaling a reaction, a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> can help you sort out what is likely going on in just a few minutes.

Moderate alcohol use is not strictly forbidden with Farxiga (dapagliflozin), but adults over 65 face higher risks because alcohol can amplify dehydration, low blood pressure, dizziness, and fall risk that this SGLT2 inhibitor already makes more likely. Heavy or binge drinking is the bigger concern, as it can trigger dangerously low blood sugar (especially if you also take insulin or a sulfonylurea) and raise the risk of ketoacidosis, which can occur even when blood sugar looks normal. Kidney function, other medications, and how much you eat and drink alongside alcohol all change the picture. There are several important factors and warning signs to consider, so see below to understand more before assuming an occasional drink is safe for you. If you are unsure whether your symptoms after drinking are harmless or a sign of dehydration, hypoglycemia, or ketoacidosis, a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> can help you sort out what is likely going on and decide whether to monitor at home, call your prescriber, or seek urgent care.

Alcohol does not directly interact with Keflex (cephalexin), so moderate drinking is unlikely to stop the antibiotic from working, but there are several important factors to consider below, including worsened side effects like nausea, dizziness, stomach upset, dehydration, and slower healing. Unlike metronidazole or tinidazole, cephalosporins such as Keflex do not typically cause the severe flushing reaction some antibiotics do, though your infection type, kidney function, and other medications still matter. See below to understand when it is safest to skip alcohol entirely until your course is finished. If you are unsure whether your symptoms are improving, worsening, or being masked by alcohol, a free, instant online <a href="https://ubiehealth.com/">symptom check</a> can help you sort out what is likely going on in just a few minutes.

Coffee is usually acceptable in moderation with methylprednisolone, though caffeine can intensify common steroid side effects such as insomnia, jitteriness, rapid heartbeat, and stomach irritation. Alcohol is generally discouraged, because both alcohol and corticosteroids irritate the stomach lining and together raise the risk of ulcers and gastrointestinal bleeding, while alcohol can also elevate blood sugar, worsen mood swings, and contribute to bone loss during longer courses. Your dose, how long you are taking it, and conditions like diabetes, ulcers, or liver disease all change how cautious you should be, and there are several important details to consider below. Because your risk depends on your specific dose, health history, and the symptoms you are already experiencing, it helps to get a clearer picture before your next cup or drink.

Yes, cranberry juice is generally safe to drink while taking antibiotics for a UTI, but it does not replace them, and there are several important factors to consider. Cranberry may help discourage bacteria from sticking to the bladder wall, yet research shows it does not cure an active infection, and large amounts can interact with blood thinners like warfarin or irritate the stomach. Sugary cranberry cocktails, acidity, and certain medication timing issues can also matter more than most people expect. See below to understand when cranberry juice helps, when it may cause problems, and which UTI symptoms mean you should contact a clinician right away.

Because spironolactone is a potassium-sparing diuretic, it can raise blood potassium, so potassium-based salt substitutes (potassium chloride) are usually discouraged, while moderate amounts of bananas and other potassium-rich foods are often acceptable for people with normal kidney function. Your safe limit depends on several factors, including your dose, kidney function, and whether you also take ACE inhibitors, ARBs, NSAIDs, or potassium supplements, and warning signs of high potassium such as muscle weakness, numbness, or an irregular heartbeat deserve prompt attention. There are important details to consider before changing your diet, so see below for the complete answer. If you are unsure whether your symptoms, medications, or diet are putting your potassium at risk, a few minutes of structured questions can help you decide whether to call your prescriber, get a blood test, or seek urgent care.

Yes, in most cases you can eat and drink normally before a complete blood count (CBC) with differential, since this test does not typically require fasting. However, there are several important factors to consider, including whether your provider ordered other blood work at the same time, such as a glucose or lipid panel, which may require 8 to 12 hours of fasting. Certain medications, supplements, recent illness, dehydration, and strenuous exercise can also influence your results, so see below to understand more before your appointment.

Yes, Brazil nuts can usually be eaten while taking levothyroxine, but timing and portion size matter more than most people realize, since the selenium, fiber, and fat they contain can influence thyroid hormone absorption and metabolism. Most guidance suggests taking levothyroxine on an empty stomach with water and waiting 30 to 60 minutes before eating nuts or any food, and limiting Brazil nuts to roughly one or two per day to avoid excess selenium. There are several important factors to consider, including your dose, other supplements, and any symptoms of over- or under-treatment, so review the complete details below before changing your routine. If you are noticing fatigue, palpitations, hair changes, weight shifts, or brain fog while on thyroid medication, those clues deserve attention rather than guesswork.

Giardia is most often caught by swallowing untreated water while swimming in lakes, rivers, or ponds, and dog-to-human spread is possible though uncommon, since most dogs carry giardia strains that rarely infect people. Symptoms such as watery or greasy diarrhea, gas, bloating, cramps, and fatigue usually appear one to three weeks after exposure and can come and go, so timing matters when identifying the source. Several important factors, including your immune status, whether household members are also sick, and when testing or treatment is needed, are covered below.

Yes, pregnancy is possible if an IUD has shifted, partially expelled, or moved out of the uterus, because it may no longer prevent fertilization or implantation effectively. Warning signs include feeling the plastic stem, strings that are longer, shorter, or missing, new cramping or unusual bleeding, and pain during sex, though some displaced IUDs cause no symptoms at all. Risk levels vary by IUD type, how far it moved, and how much time has passed, and several important factors are outlined below, including when backup contraception and a pregnancy test are needed.

Yes, a yeast infection can sometimes be passed to a sexual partner, though it is not classified as a sexually transmitted infection and many partners never develop symptoms. Risk factors like a weakened immune system, recent antibiotic use, diabetes, and uncircumcised anatomy make transmission and symptoms more likely, and men may notice itching, redness, or irritation of the penis while women may experience discharge, burning, and itching. Whether you should avoid sex, use condoms, or have your partner treated at the same time depends on several important factors explained below. Because similar symptoms can also signal bacterial vaginosis, trichomoniasis, or other STIs that require different treatment, guessing wrong can prolong discomfort and delay proper care.

Stopping metoprolol on your own is not recommended, even if your heart rate feels too slow, because abruptly quitting a beta blocker can trigger rebound effects like a racing heart, spiking blood pressure, chest pain, or in some cases a heart attack. A resting pulse under 60 beats per minute may still be safe and expected on this medication, but symptoms such as dizziness, fainting, extreme fatigue, or shortness of breath signal that your dose likely needs to be adjusted or tapered by your prescriber. Several factors matter here, including your baseline heart rhythm, other medications, and why the drug was prescribed, so see below to understand more before making any changes.
