Warnings
Cardiovascular risk
• Nonsteroidal anti-inflammatory drugs (NSAIDs) may increase risk of serious cardiovascular thrombotic events, myocardial infarction (MI), and stroke, which can be fatal
• Risk may increase with duration of use
• Patients with existing cardiovascular disease or risk factors for such disease may be at greater risk
• NSAIDs are contraindicated for perioperative pain in setting of coronary artery bypass graft (CABG) surgery
Gastrointestinal risk
• NSAIDs increase risk of serious GI adverse events, including bleeding, ulceration, and gastric or intestinal perforation, which can be fatal
• GI adverse events may occur at any time during use and without warning symptoms
• Elderly patients are at greater risk for serious GI events
Recommendations for Patient
• If pregnant; ask a health professional before use.
• Use caution in asthma (bronchial), cardiac disease, congestive heart failure (CHF), hepatic or renal impairment, hypertension.
• Long-term administration of NSAIDs may result in renal papillary necrosis and other renal injury.
Pregnancy Considerations
Category C
Breastfeeding Considerations
Because of its extremely low levels in breastmilk, short half-life and safe use in infants in doses much higher than those excreted in breastmilk, ibuprofen is a preferred choice as an analgesic or anti-inflammatory agent in nursing mothers.
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: Maybe acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.
C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.
D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.
X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.
NA: Information not available.
