Common side effects include stomach upset and heartburn; serious risks include bleeding and kidney damage with long-term use.
Take the lowest effective dose for the shortest time needed to reduce health risks.
Always discuss Aleve use with your healthcare provider, especially if you take other medications or have heart, kidney, or stomach conditions.
Aleve (Generic Naproxen Sodium) Overview
Aleve is a brand name for naproxen sodium, a nonsteroidal anti-inflammatory drug (NSAID). It belongs to a class of medications that reduce pain, fever, and inflammation by blocking chemicals in your body that cause these symptoms. The sodium in naproxen sodium helps your body absorb the medication faster than regular naproxen, which is why Aleve works quickly—typically within 30 minutes.
Aleve is used to treat mild to moderate pain from headaches, muscle aches, backaches, minor arthritis pain, menstrual cramps, and the common cold. Because it lasts longer than other over-the-counter pain relievers, you may only need to take it every 8 to 12 hours instead of every 4 to 6 hours like ibuprofen.
Generic vs Brand-Name Drugs are equally safe and effective. Generic naproxen sodium contains the exact same active ingredient as brand-name Aleve, so it works the same way in your body. The main difference is cost—generic versions are usually cheaper. This information is educational and does not replace advice from your healthcare provider.
Side Effects
Aleve is generally well tolerated when taken as directed, but like all medications, it can cause unwanted effects. Most side effects are mild and go away on their own, though some people may experience more bothersome symptoms.
Common Side Effects
Stomach upset or indigestion — Your stomach may feel uncomfortable, gassy, or queasy. Taking Aleve with food or milk can help prevent this.
Heartburn — You may feel a burning sensation in your chest or throat. This happens because NSAIDs can irritate the lining of your stomach.
Nausea — Feeling sick to your stomach is a common reaction, especially if you take Aleve on an empty stomach.
Dizziness or headache — Some people feel lightheaded or develop a headache while taking this medication.
Rash or itching — Mild skin irritation or allergic reactions may occur in sensitive individuals.
Serious Side Effects
Gastrointestinal bleeding — NSAIDs can cause bleeding in your stomach or intestines, which may appear as black or bloody stools, or vomiting blood. This is more likely with long-term use or in people over 65.
Allergic reactions — Serious allergic responses including swelling of the face, tongue, or throat, or difficulty breathing require immediate medical attention.
Heart attack or stroke — Long-term NSAID use may increase your risk of heart problems and blood clots, especially if you have heart disease or high blood pressure.
Kidney damage — Extended use of Aleve can affect kidney function, particularly in people with existing kidney disease or those taking certain blood pressure medications.
Liver problems — Rarely, NSAIDs can cause liver injury. Signs include yellowing of the skin or eyes, dark urine, or severe abdominal pain.
When to Seek Medical Attention
Contact your doctor if you experience stomach pain, blood in stool, persistent nausea, or signs of an allergic reaction like hives or difficulty breathing. If you develop chest pain, shortness of breath, or signs of stroke (weakness, slurred speech, vision changes), seek emergency care immediately. Do not wait to see if symptoms go away—some NSAID-related complications develop gradually and can become serious.

Important: If you miss a dose, take the next dose when it's due—do not double up. Do not stop taking Aleve without talking to your doctor, especially if you've been using it for a long time. Do not use Aleve for more than 10 consecutive days unless your doctor says it's okay. If you accidentally take more than the recommended dose, call poison control or seek emergency care.
Drug Interactions
Aleve can interact with other medications and supplements, potentially reducing effectiveness or increasing the risk of side effects. Always tell your doctor and pharmacist about all medications, vitamins, and herbal supplements you take before using Aleve.
Blood Thinners (Warfarin, Apixaban)
NSAIDs like naproxen can increase bleeding risk when combined with blood thinners. This combination may raise your chances of serious bleeding in the stomach, brain, or other organs.
ACE Inhibitors and ARBs (Lisinopril, Losartan)
Aleve may reduce the effectiveness of these blood pressure medications and increase your risk of kidney damage. Your doctor may need to monitor your kidney function more closely.
Aspirin
Taking Aleve with aspirin increases your risk of stomach bleeding and ulcers without providing extra pain relief. Avoid combining these medications.
Lithium
Naproxen can increase lithium levels in your blood, which may cause lithium toxicity. If you take lithium for bipolar disorder, your doctor needs to monitor your levels carefully while you use Aleve.
Diuretics (Water Pills)
Aleve may reduce how well water pills work and increase your risk of kidney problems. This combination is especially risky in older adults or people with existing kidney disease.
Corticosteroids
Using Aleve with steroids like prednisone increases your risk of stomach ulcers and bleeding. If you must take both, your doctor may recommend a stomach-protective medication.

Frequently Asked Questions
Get answers to common questions about Aleve and naproxen sodium.
Yes, generic naproxen sodium is chemically identical to brand-name Aleve. Both contain the same active ingredient in the same strength and work the same way in your body. Generic vs Brand Name Drugs are FDA-approved and equally effective, but generics usually cost less. The main difference is the brand name and packaging.
The package recommends not using Aleve for more than 10 days without talking to your doctor. However, long-term regular use of NSAIDs increases your risk of serious side effects like heart attacks, strokes, and stomach bleeding. If you need pain relief for longer than 10 days, contact your healthcare provider to discuss safer options and the lowest effective dose for your situation.
No, do not combine Aleve with other NSAIDs like ibuprofen or aspirin, as this increases your risk of stomach bleeding and ulcers. You may combine Aleve with acetaminophen (Tylenol), but talk to your doctor first. Never exceed recommended doses of any medication. Take Aleve with Gabapentin only under doctor supervision, as interactions are possible.
Aleve can affect kidney and liver function, especially with long-term use or in people with existing kidney or liver disease. Most people who use Aleve occasionally as directed do not experience lasting damage. However, if you use it regularly or have kidney or liver disease, your doctor should monitor your kidney and liver function with blood tests.
If you take more Aleve than recommended, call poison control at 1-800-222-1222 or go to the nearest emergency room. Do not wait for symptoms to appear. Keep the Aleve bottle with you so medical staff can see exactly what and how much you took. Overdose symptoms may include stomach pain, nausea, vomiting, drowsiness, or loss of consciousness.
The Bottom Line
Aleve (naproxen sodium) is an effective over-the-counter pain reliever that works longer than many alternatives, making it convenient for mild to moderate pain. The generic version offers the same benefits at a lower cost than the brand name. However, NSAIDs carry real risks—especially heart attack, stroke, and stomach bleeding—particularly with long-term use or in people with certain health conditions. Use the lowest dose for the shortest time needed, take it with food, and talk to your doctor before starting, especially if you have heart disease, high blood pressure, kidney disease, or take other medications.
