Drug interactions
- HighMethotrexateL01BA01
Mechanism: NSAIDs decrease renal clearance of methotrexate by inhibiting tubular secretion, leading to increased plasma concentration and its hematologic and gastrointestinal toxicity.
Recommendation: Avoid concomitant use, especially with high-dose methotrexate (>15 mg/week). If necessary, monitor renal function and signs of methotrexate toxicity closely.
AEMPS CIMAClinical Pharmacology
- HighWarfarinB01AA03
Mechanism: Additive pharmacodynamic effect: increased risk of bleeding due to platelet inhibition by ibuprofen and anticoagulation by warfarin. Ibuprofen may also displace warfarin from protein binding sites.
Recommendation: Avoid concomitant use. If unavoidable, monitor INR closely and educate the patient on signs of bleeding.
