What Are Warnings and Precautions for Ketoprofen?
- Cardiovascular Risk
- Nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the risk of serious cardiovascular thrombotic events, myocardial infarction (MI), and stroke, which can be fatal.
- The risk may increase with the duration of use.
- Patients with risk factors for or existing cardiovascular disease may be at greater risk.
- NSAIDs are contraindicated for perioperative pain in the setting of coronary artery bypass graft (CABG) surgery (increased risk of MI and stroke).
- Gastrointestinal Risk
- NSAIDs increase the risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal.
- Gastrointestinal adverse events may occur at any time during use and without warning symptoms.
- Elderly patients are at greater risk for serious gastrointestinal events.

Effects of Drug Abuse
- No information available
- See "What Are Side Effects Associated with Using Ketoprofen?"
- See "What Are Side Effects Associated with Using Ketoprofen?"
- Use caution in asthma (bronchial), cardiac disease, chronic heart failure, hypertension, renal impairment, and systemic lupus erythematosus (SLE).
- Long-term administration of NSAIDs may result in renal papillary necrosis and other renal injuries; patients at greatest risk include the elderly, or those with impaired renal function, hypovolemia, heart failure, liver dysfunction, salt depletion, and individuals taking diuretics, ACE inhibitors, or angiotensin receptor blockers (ARBs).
- Heart Failure (HF) risks.
- NSAIDs have the potential to trigger heart failure by prostaglandin inhibition that leads to sodium and water retention, increased systemic vascular resistance, and blunted response to diuretics.
- NSAIDs should be avoided or withdrawn whenever possible.
- American Heart Association (AHA)/American College of Cardiology (ACC) Heart Failure Guidelines; Circulation. 2016; 134.
Pregnancy and Lactation
- Use of ketoprofen may be acceptable during pregnancy. Either animal studies show no risk or human studies are not available or animal studies showed minor risk and human studies were done and showed no risk. Use ketoprofen late in pregnancy only in LIFE-THREATENING emergencies when no safer drug is available. Positive evidence of human fetal risk: premature closure of ductus arteriosus closure.
- The Quebec Pregnancy Registry identified 4705 women who had spontaneous abortions by 20 weeks gestation; each case was matched to 10 control subjects (n=47,050) who had not had spontaneous abortions; exposure to nonaspirin NSAIDs during pregnancy was documented in approximately 7.5% of cases of spontaneous abortions and approximately 2.6% of controls. (CMAJ, September 6, 2011; DOI:10.1503/cmaj.110454).
