Ketofen Ketoprofen Methotrexate
ModerateTaking ketoprofen with methotrexate at doses greater than 15 mg/week increases the risk of haematologic toxicity from methotrexate, particularly at high doses (>15 mg/week). This may happen because ketoprofen can displace protein-bound methotrexate and decrease its clearance through the kidneys.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
