Frequently Asked Questions


The labeling for ALEVE is consistent with over-the-counter (OTC) nonsteroidal anti-inflammatory drug (NSAID) labeling and a “Stomach Bleeding Warning” designed to inform consumers that the product contains an NSAID, which "may cause severe stomach bleeding."1

  • The warning informs consumers that the risk of stomach bleeding is higher if: they are age 60 or older, have had stomach ulcers or bleeding problems, take a blood thinning (anticoagulant) or steroid drug, take other drugs containing prescription or nonprescription NSAIDs (aspirin, ibuprofen, naproxen, or others), have 3 or more alcoholic drinks every day while using the product or take more or for a longer time than directed.1
  • Consumers are advised to ask a doctor before use if: the stomach bleeding warning applies to them, or if they have a history of stomach problems such as heartburn.1
  • Consumers are advised to stop use and ask a doctor if: they experience any of the following signs of stomach bleeding including feeling faint, vomiting blood, bloody or black stools, or stomach pain that does not get better.1
  • The risk of GI bleeding with NSAID use is dose dependent and impacted by the duration of use.2 The minimum effective dose for the shortest duration of NSAID use is generally recommended to minimize undesirable effects including GI side effects.

What data are available regarding naproxen sodium and GI safety?

A meta-analysis of 46 randomized, controlled studies demonstrated that the incidence of patient- reported GI adverse events (nausea and `dyspepsia, and were the most commonly reported) with OTC naproxen sodium was comparable with placebo.3

In patients taking naproxen sodium, the reporting rate of GI bleeding from clinical trial data was rare (0.01% to <0.1%).4 A review of 101 short-term studies (30 days or less) with naproxen at OTC doses (up to 600 mg a day) found that the incidence of new-onset upper GI bleeding ranged from 0% to 0.036%.4 In 1 long-term studies (1 year in length) with naproxen at OTC doses (up to or equal to 440 mg a day), there was no significant difference between naproxen sodium and placebo in the incidence of new onset GI bleeding.5
