Aleve (naproxen sodium) should not be taken for more than 10 days in a row for pain, or more than 3 days in a row for fever, unless a doctor directs otherwise. Dosing limits also apply daily: most adults should not exceed 2 to 3 caplets in 24 hours, and adults over 65 are advised to take no more than 1 caplet every 12 hours. Taking it longer than labeled raises the risk of stomach bleeding, ulcers, kidney problems, and heart issues, and certain conditions and medications make even short-term use risky. There are several important factors to consider, including what ongoing pain lasting more than 10 days may signal, so see below for the complete details.
If your pain or fever is lasting long enough that you are counting days on a bottle of Aleve, that is a signal worth investigating rather than masking. A free, instant, online symptom check can help you organize your symptoms, understand possible causes, and decide whether you need to see a doctor now or can safely keep monitoring at home.

How long should you take Aleve?
Aleve (naproxen sodium) is a popular over-the-counter nonsteroidal anti-inflammatory drug (NSAID) used for relief of pain, inflammation and fever. Like all medications, it must be used correctly to balance effectiveness against potential risks. Below, you’ll find evidence-based guidance on how many days in a row you can safely take Aleve—and when it’s time to seek medical advice.
When taking Aleve without a doctor’s prescription, follow the directions on the label:
These limits come from the FDA-approved drug label and are designed to minimize risks like stomach bleeding, kidney stress and cardiovascular complications.
Longer courses of NSAIDs increase the chance of side effects. Key concerns include:
Sticking to the 10-day (pain) and 3-day (fever) limits helps you get relief without unnecessarily raising these risks.
To make the most of Aleve with the least risk:
Use the lowest effective dose
Take with food or milk
Stay hydrated
Avoid alcohol
Watch for warning signs
If any of these occur, stop Aleve and speak to a doctor immediately.
If you need NSAID therapy beyond OTC limits:
If your symptoms persist beyond recommended days:
…consider further evaluation rather than continuing OTC Aleve. A prolonged problem may need:
To help decide your next step, try a free, online symptom check, using the doctor approved Ubie Symptom Checker. It can guide you on whether self-care is enough or you should see a provider.
Always mention your full medical history to any healthcare professional before starting extended NSAID therapy.
If you need pain or fever relief beyond a few days, consider:
These options may reduce reliance on oral NSAIDs.
Serious or life-threatening symptoms—such as chest pain, difficulty breathing, severe abdominal pain, sudden weakness, or rapidly worsening swelling—require immediate medical attention. Always speak to a doctor if you have concerns about your health or need advice on safe, long-term pain management.
