Avoid alcohol. Take with food or milk to minimize gastric irritation. Grapefruit juice may modestly increase ibuprofen absorption but clinical significance is low; no strict restriction. Administer with a full glass of water.
Ibuprofen can increase the risk of stomach bleeding when taken with alcohol. No specific food restrictions, but taking with food or milk can reduce GI irritation.
First trimester: Avoid due to potential increased risk of miscarriage and congenital malformations (cardiac defects, gastroschisis). Second trimester: Use only if clearly needed; no clear teratogenic risk but may cause premature closure of ductus arteriosus. Third trimester: Contraindicated due to risk of premature ductus arteriosus closure, oligohydramnios, and neonatal renal impairment.
First and second trimester: Increased risk of miscarriage and congenital malformations (particularly cardiac defects) associated with NSAID use. Third trimester: Known risk of premature closure of ductus arteriosus, oligohydramnios, and neonatal renal impairment; contraindicated after 30 weeks gestation.
Ibuprofen is excreted into breast milk in very low amounts (M/P ratio approximately 0.01). Considered compatible with breastfeeding; use lowest effective dose for shortest duration. Monitor infant for rash, gastrointestinal effects, or drowsiness.
Ibuprofen is excreted into breast milk in low concentrations (M/P ratio approximately 0.01-0.03). Considered compatible with breastfeeding by the American Academy of Pediatrics; use lowest effective dose for shortest duration.
No specific dose adjustment recommended for pregnancy-related pharmacokinetic changes. However, due to increased plasma volume and renal clearance, therapeutic efficacy may be reduced; use lowest effective dose. Avoid in third trimester.
Increased plasma volume and renal clearance in pregnancy may reduce drug levels; however, no standard dose adjustment recommended. Use lowest effective dose, avoid in third trimester.
Ibuprofen (IBU-TAB 200) is an NSAID; avoid in patients with Cr Cl <30 m L/min. Dose adjustment not needed for mild hepatic impairment but contraindicated in severe hepatic disease. Use lowest effective dose for shortest duration to minimize renal and GI risk. Can mask signs of infection; monitor for fever in at-risk patients. Not recommended in late pregnancy (after 30 weeks) due to risk of premature ductus arteriosus closure.
Ibuprofen is a nonselective COX inhibitor with anti-inflammatory, analgesic, and antipyretic effects. Avoid in patients with aspirin allergy, active peptic ulcer, or severe renal impairment. Use lowest effective dose for shortest duration to minimize GI and cardiovascular risks. Not recommended in patients with advanced chronic kidney disease (e GFR <30 m L/min/1.73 m²). For acute pain, ibuprofen 200-400 mg every 6 hours PRN. Monitor for signs of GI bleeding, hypertension, and fluid retention.

No interactions on record
"Concomitant use of Ibuprofen (a nonsteroidal anti-inflammatory drug, NSAID) and Methylprednisolone (a systemic corticosteroid) synergistically increases the risk of gastrointestinal (GI) ulceration, bleeding, and perforation due to additive inhibition of prostaglandin synthesis and mucosal protection. Additionally, Ibuprofen may potentiate the immunosuppressive effects of Methylprednisolone, elevating infection risk. This interaction can lead to serious clinical outcomes, including acute GI hemorrhage, perforation, and impaired wound healing."
"The combination of olopatadine, an antihistamine with sedative properties, and ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID), may result in additive central nervous system (CNS) depression, leading to increased sedation, dizziness, and impaired psychomotor function. Ibuprofen can inhibit the metabolism of olopatadine via competition for hepatic CYP450 enzymes, potentially elevating olopatadine plasma concentrations and prolonging its systemic effects. Clinically, patients may experience exacerbated drowsiness, reduced alertness, and increased risk of falls or accidents, especially in the elderly or those with compromised hepatic function."
"Ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID), can decrease the metabolism of pioglitazone, a thiazolidinedione antidiabetic agent, by inhibiting cytochrome P450 2C8 (CYP2C8) enzyme activity. This inhibition elevates plasma concentrations of pioglitazone, potentially enhancing its hypoglycemic effects and increasing the risk of adverse reactions such as edema, weight gain, and heart failure exacerbation. Clinically, concomitant use may lead to improved glycemic control but also raises concerns for dose-dependent toxicities, necessitating careful monitoring and possible dose adjustment of pioglitazone."
