Q.
Does Zinc Really Shorten a Cold? Dosage and Safety Tips
A.
Zinc can modestly shorten a cold by about 1 to 2 days when started within 24 hours, ideally as zinc acetate or gluconate lozenges totaling 75 to 100 mg elemental zinc per day, divided every 2 to 3 hours while awake for up to 5 to 7 days. It is not a cure. There are several safety and interaction issues to weigh, including nausea and metallic taste, avoiding intranasal sprays due to risk of permanent loss of smell, limiting high doses to short courses to prevent copper deficiency, and checking for interactions with antibiotics and other medicines; see the complete guidance below to understand who should be cautious and how to choose next steps.

Q.
Can’t Shake This Cold? Why Your Body Is Struggling & Medically Approved Next Steps
A.
If your cold lingers beyond 7 to 10 days, there are several factors to consider: slow immune recovery from stress or poor sleep, catching a second virus, a common post-viral cough, allergies, or less commonly complications like sinusitis, ear infection, or bronchitis. Medically approved next steps range from supportive care to prompt medical review for red flags like no improvement after 10 days, worsening after initial recovery, high fever, trouble breathing, or a cough lasting more than 3 to 4 weeks; for critical details that could change your next step, including who should seek care sooner and a free symptom check, see below.

Q.
Why Won’t It Go Away? The Reality of Upper Respiratory Infections & Medically Approved Next Steps
A.
There are several factors to consider: most upper respiratory infections are viral and improve in 7 to 10 days, though a cough can linger 2 to 3 weeks; if it is not going away it may still be the normal course, a new virus, post-viral inflammation, or a secondary bacterial issue or another condition like allergies, asthma, reflux, COVID, or chronic sinusitis. Start with rest, hydration, saline, and targeted over the counter symptom relief, and seek medical care for severe symptoms or if illness lasts beyond 10 to 14 days, since antibiotics are only used when bacterial infection is suspected. Key timelines, warning signs, and step by step guidance that could change your next move are detailed below.

Q.
Is upper respiratory infection contagious?
A.
Yes, most upper respiratory infections are contagious, spreading through droplets, aerosols, and contaminated hands or surfaces; people are infectious about a day before symptoms, most in the first 3 to 4 days, and sometimes longer in children or immunocompromised individuals. There are several factors to consider, including how long you may shed virus, who is at higher risk, and the best ways to prevent spread and when to seek care. See the complete guidance below to understand these details and choose the right next steps.

Q.
What causes upper respiratory infection?
A.
Most upper respiratory infections are caused by viruses such as rhinovirus, seasonal coronaviruses including COVID-19, influenza, RSV, parainfluenza, and adenovirus, which spread via respiratory droplets, close contact, and contaminated surfaces. Less often, bacteria can cause or follow a viral infection, and factors like colder seasons, young or older age, crowded settings, smoking, air pollution, allergies, chronic conditions, and stress increase risk and may affect next steps; see the complete details below.

Q.
What is the fastest way to get rid of a upper respiratory infection?
A.
There is no instant cure, but the fastest way to feel better is to rest, stay well hydrated, use OTC pain and congestion relief, breathe moist air, and start zinc lozenges within 24 hours to shorten symptoms by about 1 to 2 days, with vitamin C offering a small additional benefit. There are important details about safe dosing, side effects, when to seek medical care, and red flag symptoms that could change your next steps; see the complete guidance below.

Q.
Can you take robitussin while pregnant?
A.
Yes, Robitussin DM with dextromethorphan and guaifenesin is generally considered low risk in pregnancy when taken as directed, especially after the first trimester. There are several factors to consider, including choosing single-ingredient or DM-only products, avoiding phenylephrine, using non-drug options first, correct dosing, and when to seek medical care, so see the complete guidance below to decide your next steps or confirm with your clinician.

Q.
Does robitussin make you sleepy?
A.
Most Robitussin formulas with dextromethorphan and/or guaifenesin are not sedating, but Nighttime or PM versions with diphenhydramine can make you drowsy, and products with pseudoephedrine may even feel stimulating. There are several factors to consider, including age, other sedating medicines, alcohol, dose, and health conditions; see below for which ingredients to choose or avoid, tips to prevent drowsiness, and when to seek medical care.
