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 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 the setting of coronary artery bypass graft (CABG) surgery

Gastrointestinal risk

NSAIDs increase the 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

• Aspirin allergy
• Perioperative pain in the setting of coronary artery bypass graft (CABG) surgery
• Preterm infants with untreated proven or suspected infection; bleeding with active intracranial hemorrhage or GI bleed; thrombocytopenia, coagulation defects, proven or necrotizing enterocolitis, significant renal impairment, congenital heart disease where patency or the PDA is necessary for pulmonary or systemic blood flow

Effects of Drug Abuse

None.

Short-Term Effects

• See "What Are Side Effects Associated with Using Ibuprofen?"

Long-Term Effects

• Long-term opioid use may cause secondary hypogonadism, which may lead to sexual dysfunction, infertility, mood disorders, and osteoporosis.
• See "What Are Side Effects Associated with Using Ibuprofen?"

Cautions

Use caution in asthma (bronchial), cardiac disease, congestive heart failure (CHF), hepatic or renal impairment, hypertension. bleeding disorders, duodenal/gastric/peptic ulcer, stomatitis, systemic lupus erythematosus (SLE), ulcerative colitis, upper GI disease, late pregnancy (may cause premature closure of ductus arteriosus).

Long-term administration of NSAIDs may result in renal papillary necrosis and another renal injury; patients at greatest risk include elderly individuals; those with impaired renal function, hypovolemia, heart failure, liver dysfunction, or salt depletion; and those taking diuretics, angiotensin-converting enzyme (ACE) inhibitors, or angiotensin receptor blockers.

• Junior Advil (100 mg): Doses higher than recommended may cause stomach bleeding.
• May cause serious adverse reactions, including exfoliative dermatitis, toxic epidermal necrolysis, Steven's Johnson syndrome reported.
• Children's and Junior Advil (50 mg, 100 mg): May cause severe and persistent sore throat.
• Fever, rash, abdominal pain, nausea, liver dysfunction, and meningitis have occurred in patients with collagen-vascular disease, especially SLE.
• Blurred vision, scotomata, and changes in color vision were reported; discontinue therapy if symptoms occur.
• Platelet aggregation and adhesion may be decreased; monitor patients with coagulation disorders receiving the therapy.
• The risk of hyperkalemia may increase in patients with diabetes, the elderly, renal disease, or with concomitant use of agents that can induce hyperkalemia including ACE inhibitors; monitor potassium closely.
• May cause drowsiness and dizziness; may impair physical or mental abilities to operate heavy machinery or driving.
• Not for use right before or after heart surgery.

Heart Failure (HF) risk

• NSAIDs have the potential to trigger HF 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
• AHA/ACC Heart Failure Guidelines; Circulation. 2016; 134

Pregnancy and Lactation

• At or after 30 weeks gestation: Ibuprofen may cause premature closure of ductus arteriosus; avoid during 1st and 3rd trimesters.
• 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 non-aspirin NSAIDs during pregnancy was documented in approximately 7.5% of cases of spontaneous abortions and approximately 2.6% of controls.
• Ibuprofen is excreted into human breast milk at extremely low levels. Ibuprofen has a short half-life and is considered safe in infants in doses much higher than those excreted in breast milk. Ibuprofen is considered the preferred choice for analgesia or inflammation in breastfeeding women (LactMed from NIH).
