Naproxen, sold over the counter as Aleve and by prescription as Naprosyn and Anaprox, is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain and reduce swelling. After surgery, it is sometimes used as part of a multimodal pain plan, but it is not right for every patient or procedure. This guide explains when naproxen can help and what precautions matter most.
How Naproxen Works and How It Differs from Ibuprofen
Naproxen blocks cyclooxygenase (COX) enzymes, which produce prostaglandins, the chemical signals that cause pain, fever, and inflammation.
The key difference from ibuprofen: naproxen lasts 8 to 12 hours per dose, compared to 4 to 6 hours for ibuprofen. This means fewer daily doses.
Over-the-counter naproxen sodium (Aleve) is 220 mg per tablet. Prescription naproxen comes in 250, 375, and 500 mg tablets.
Standard OTC adult dosing: 220 mg every 8 to 12 hours. Do not exceed 660 mg in 24 hours unless directed by a provider.
Prescription doses are higher and managed by your provider. Do not exceed the prescribed amount.
When Naproxen Is Used After Surgery
Naproxen is most commonly used after dental procedures, orthopedic surgery (joint replacement, fracture repair), and soft tissue surgeries where inflammation is a significant source of pain.
It is often combined with acetaminophen to provide better pain control with lower doses of each medication.
Your surgeon may specify a start date, since some procedures require avoiding NSAIDs for the first 24 to 48 hours due to bleeding risk.
Take naproxen with food or a full glass of water to reduce stomach irritation.
Do not take naproxen and ibuprofen together. They are both NSAIDs and combining them increases side effect risk without added benefit.
Who Should Avoid Naproxen After Surgery
Patients with kidney disease or reduced kidney function: NSAIDs can further reduce blood flow to the kidneys, especially when combined with dehydration or diuretics.
Patients with a history of peptic ulcer disease or gastrointestinal bleeding: naproxen increases risk of stomach and intestinal bleeding.
Patients on blood thinners (warfarin, apixaban, rivaroxaban): naproxen can increase bleeding risk when combined with anticoagulants.
Patients who had certain cardiac, vascular, or kidney surgeries: your surgeon will specify whether NSAIDs are restricted.
Patients over 65: older adults face higher risk of GI bleeding and kidney impairment from NSAIDs. Use the lowest effective dose for the shortest time.
If you take a proton pump inhibitor (PPI) such as omeprazole, it can reduce but does not eliminate the stomach risk from naproxen.
Signs of a Naproxen-Related Problem
Stomach pain, black or tarry stools, or vomiting blood: stop taking naproxen and seek care immediately. These may indicate GI bleeding.
Reduced urination, swelling in the legs or ankles, or unexplained weight gain: these can signal kidney problems.
Chest pain, shortness of breath, or sudden leg swelling: NSAIDs carry a small cardiovascular risk, particularly with long-term use.
Skin rash, hives, or difficulty breathing after taking naproxen: this may indicate an allergic reaction. Stop immediately and seek care.
Frequently asked
Questions patients ask.
Is naproxen stronger than ibuprofen?
They are roughly comparable in anti-inflammatory strength at equivalent doses. Naproxen's main advantage after surgery is its longer duration of action, meaning you take it less often. Ibuprofen offers more flexibility for dose adjustments and is available in more forms (including liquid). Your provider can recommend which is better for your situation.
Can I take naproxen with acetaminophen after surgery?
Yes. Acetaminophen and naproxen work through different pathways and are safe to take together. This combination often provides better pain relief than either alone and is a common strategy in post-surgical pain management. Follow the dosing instructions for each medication separately.
My surgeon said no NSAIDs after my procedure. Does that include Aleve?
Yes. Aleve (naproxen sodium) is an NSAID. If your surgeon has restricted NSAIDs, this includes naproxen, ibuprofen, aspirin (at anti-inflammatory doses), and celecoxib. Use acetaminophen for pain unless your surgeon directs otherwise.
How long can I take naproxen after surgery?
For most post-surgical pain, 5 to 10 days of NSAID use is typical. Use the lowest effective dose for the shortest time. If you still need it beyond that, check with your provider to rule out complications and assess whether continued NSAID use is appropriate.
