FAERS contains 12,665 submissions naming this drug from 2003 through 2026; the top three reactions cited are headache, pain, and fatigue.

Most-Reported Reactions

Counts of the reactions most often cited in FAERS submissions that named Ketoprofen. Inclusion here does not establish causation - submitters describe what was observed, not what was confirmed. One submission can list several reactions, so the totals exceed the report count.

Severity Outcomes

Severity flags recorded across the 12,665 FAERS submissions that named Ketoprofen. Each bar shows the count of those reports carrying that flag. A single case can carry more than one (a hospitalization that became life-threatening, for example), so these bars are independent rates - they don't sum to 100%. Inclusion of a case under any flag does not establish that the drug caused the outcome.

From the FDA-Approved Label

Excerpts from the official FDA-approved prescribing information for Ketoprofen. This is the authoritative source on indications, warnings, and known adverse reactions.

Indications

Carefully consider the potential benefits and risks of ketoprofen extended-release capsules before deciding to use ketoprofen extended-release capsules. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS ). Ketoprofen extended-release capsules are indicated for the management of the signs and symptoms of rheumatoid arthritis and osteoarthritis. Ketoprofen extended-release capsules are not recommended for treatment of acute pain because of its extended-release characteristics (see CLINICAL PHARMACOLOGY: Pharmacokinetics ).

Warnings

Cardiovascular Effects Cardiovascular Thrombotic Events Clinical trials of several COX-2 selective and nonselective NSAIDs of up to three years duration have shown an increased risk of serious cardiovascular (CV) thrombotic events, including myocardial infarction (MI) and stroke, which can be fatal. Based on available data, it is unclear that the risk for CV thrombotic events is similar for all NSAIDs. The relative increase in serious CV thrombotic events over baseline conferred by NSAID use appears to be similar in those with and without known CV disease or risk factors for CV disease. However, patients with known CV disease or risk factors had a higher absolute incidence of excess serious CV thrombotic events, due to their increased baseline rate. Some observational studies found that this increased risk of serious CV thrombotic events began as early as the first weeks of treatment. The increase in CV thrombotic risk has been observed most consistently at higher doses. To minimize the potential risk for an adverse CV event in NSAID-treated patients, use the lowest effective dose for the shortest duration possible. (continues in label)

Adverse Reactions (from label)

The incidence of common adverse reactions (above 1%) was obtained from a population of 835 ketoprofen capsules-treated patients in double-blind trials lasting from 4 to 54 weeks and in 622 ketoprofen extended-release capsules treated (200 mg/day) patients in trials lasting from 4 to 16 weeks. Minor gastrointestinal side effects predominated; upper gastrointestinal symptoms were more common than lower gastrointestinal symptoms. In crossover trials in 321 patients with rheumatoid arthritis or osteoarthritis, there was no difference in either upper or lower gastrointestinal symptoms between patients treated with 200 mg of ketoprofen extended-release capsules once a day or 75 mg of ketoprofen capsules TID (225 mg/day). Peptic ulcer or GI bleeding occurred in controlled clinical trials in less than 1% of 1,076 patients; however, in open label continuation studies in 1,292 patients the rate was greater than 2%. The incidence of peptic ulceration in patients on NSAIDs is dependent on many risk factors including age, sex, smoking, alcohol use, diet, stress, concomitant drugs such as aspirin and corticosteroids, as well as the dose and duration of treatment with NSAIDs (see WARNINGS ).
