O que dizem as bulas da FDA
Da bula de Pemetrexede (Pemfexy) · em vigor desde 2026-02-20
In patients with creatinine clearances between 45 mL/min and 79 mL/min, avoid administration of ibuprofen for 2 days before, the day of, and 2 days following administration of PEMFEXY.
If concomitant ibuprofen use cannot be avoided, monitor patients more frequently for pemetrexed adverse reactions, including myelosuppression, renal, and gastrointestinal toxicity [see Dosage and Administration ( 2.5 ), Drug Interactions ( 7 ), and Clinical Pharmacology ( 12.3 )] .
In patients with creatinine clearance between 45 mL/min and 79 mL/min: Avoid administration of ibuprofen for 2 days before, the day of, and 2 days following administration of PEMFEXY [see Dosage and Administration ( 2.5 )] .
Monitor patients more frequently for myelosuppression, renal, and gastrointestinal toxicity, if concomitant administration of ibuprofen cannot be avoided.
Increased Risk of Toxicity with Ibuprofen in Patients with Renal Impairment Exposure to pemetrexed is increased in patients with mild to moderate renal impairment who take concomitant ibuprofen, increasing the risks of adverse reactions of pemetrexed.
Da bula de Paracetamol + ibuprofeno (Combogesic) · em vigor desde 2026-08-20
NSAIDs with short elimination half-lives (e.g., diclofenac, indomethacin) should be avoided for a period of two days before, the day of, and two days following administration of pemetrexed.
Pemetrexed Clinical Impact: Concomitant use of NSAIDS and pemetrexed may increase the risk of pemetrexed-associated myelosuppression, renal, and GI toxicity (see the pemetrexed prescribing information).
Intervention: During concomitant use of COMBOGESIC and pemetrexed, in patients with renal impairment whose creatinine clearance ranges from 45 to 79 mL/min, monitor for myelosuppression, renal and GI toxicity.
In the absence of data regarding potential interaction between pemetrexed and NSAIDs with longer half-lives (e.g., meloxicam, nabumetone), patients taking these NSAIDs should interrupt dosing for at least five days before, the day of, and two days following pemetrexed administration.
