For adults, the standard Aleve (naproxen sodium 220 mg) dose is 1 tablet every 8 to 12 hours, with an option to take 2 tablets within the first hour of treatment, never exceeding 2 tablets in any 8 to 12 hour period or 3 tablets in 24 hours. Adults over age 65 should generally take only 1 tablet every 12 hours, and use should be limited to 10 days for pain or 3 days for fever unless a clinician advises otherwise. Your safe amount can change based on your age, kidney health, blood pressure, stomach ulcer history, and other medications such as blood thinners or other NSAIDs, so there are several important factors to consider before dosing. See the complete details below, including warning signs that mean you should stop taking it.
Because pain that keeps returning every 8 hours is often a signal rather than a standalone problem, it helps to look at the bigger picture instead of simply re-dosing. Take a free, instant online symptom check to better understand what may be driving your pain and what your smartest next step should be.

When you’re dealing with pain or inflammation, it’s natural to wonder: how many Aleve should you take, and how often? Aleve (naproxen sodium) is a popular over-the-counter nonsteroidal anti-inflammatory drug (NSAID) used to relieve headaches, muscle aches, arthritis pain and more. While it’s effective when used correctly, taking too much or using it for too long can lead to serious side effects. This guide explains standard dosing, safety tips and when to seek professional help.
Aleve contains naproxen sodium, which:
Aleve is intended for adults and children 12 years and older. It’s often chosen because its effects last longer than some other NSAIDs—up to 12 hours per dose.
When considering how many Aleve should you take, follow these guidelines (from the FDA-approved label):
• Adults and children 12 years and older:
– Take 1 tablet (220 mg) every 8 to 12 hours while symptoms last.
– For the first dose, you may take 2 tablets within the first hour if needed.
– After the first hour, continue with 1 tablet every 8–12 hours.
– Do not exceed 2 tablets in any 8- to 12-hour period.
– Do not exceed 3 tablets (660 mg) in a 24-hour period.
• Children under 12:
– Safety and effectiveness have not been established. Ask a doctor before giving Aleve to a child under 12.
Key points:
Aleve’s longer duration can be an advantage, but strict timing is essential:
If you find you need more pain relief before your next dose, speak with a healthcare professional rather than increasing your dose on your own.
Before using Aleve, consider these factors:
• History of stomach ulcers or gastrointestinal bleeding
• Kidney or liver disease
• Heart disease, high blood pressure or stroke risk
• Asthma or aspirin/NSAID allergy
• Pregnancy (especially in the third trimester)
• Breastfeeding
If any of the above apply to you, talk to your doctor before taking Aleve. They may recommend a different pain reliever or adjust your dose.
Aleve is generally well tolerated when used as directed. Still, watch for:
• Gastrointestinal issues:
– Upset stomach, heartburn, nausea
– More serious: bleeding, ulceration or perforation of the stomach/intestines
• Cardiovascular risks:
– Increased risk of heart attack or stroke with long-term or high-dose use
• Kidney problems:
– Reduced kidney function, especially if you’re dehydrated or have preexisting kidney disease
• Allergic reactions:
– Hives, difficulty breathing, swelling of the face or throat
• Other:
– Headache, dizziness, ringing in the ears
If you experience any severe symptoms—particularly signs of internal bleeding (black, tarry stools; severe stomach pain) or allergic reaction—stop taking Aleve and seek medical care immediately.
Aleve can interact with other medications or lifestyle factors:
Always read labels on all your medications and supplements. Consider keeping a list to share with your healthcare provider.
Aleve can be used for sudden pain (e.g., headache, menstrual cramps) or for chronic conditions (e.g., osteoarthritis). General advice:
• Short-term (a few days):
– Follow standard dosing.
– Use only as long as you need relief.
• Long-term (weeks to months):
– Discuss with your doctor.
– Regular monitoring for blood pressure, kidney function and stomach health may be necessary.
– Your physician might recommend the lowest effective dose or alternative therapies (physical therapy, topical NSAIDs).
Never self-prescribe long-term NSAID therapy without medical supervision.
No matter how familiar you are with Aleve, if you have:
• Severe or worsening pain that doesn’t improve with maximum OTC dosing
• Signs of serious side effects (e.g., unexplained bleeding, chest pain, shortness of breath)
• Questions about combining medications
• Chronic pain requiring daily medication
…you should speak to a doctor. For a quick, safe check of your symptoms, you might consider doing a free, online symptom check, using the doctor approved Ubie Symptom Checker. This tool can help you decide if you need to see a healthcare professional.
If anything feels life threatening or seriously wrong, don’t wait. Speak to a doctor right away. Your health and safety come first.
