Food

· Severity: Moderate

· Notes for Consumers: Certain food or drink such as cola may increase the risk of methotrexate side effects. Tell your doctor if you drink soft drinks before you take methotrexate.

· Notes for Professionals: Concurrent administration of oral methotrexate with food may delay the absorption of methotrexate and decrease the maximum serum concentration.

Foods that acidify the urine

· Severity: Moderate

· Notes for Consumers: Certain food or drink such as cola may increase the risk of methotrexate side effects. Tell your doctor if you drink soft drinks before you take methotrexate. Immediately report any ununsual symptom such as stomach pain, sore throat, fever, mouth sores, or problems with urination.

· Notes for Professionals: Food or drink that acidifies the urine such as cola can cause elevated methotrexate concentrations. In a patient, acute renal failure was noted 24 hours after drug receipt despite baseline normal renal function. The patient had repeated episodes of reduced urinary pH despite sodium bicarbonate administration. The urinary pH went from 8.5 to 6.5 after the patient consumed 330 ml of Coca-Cola. Urinary pH was maintained at 8 or higher once the patient stopped consuming cola. The plasma methotrexate concentration fell and urinary function eventually returned to normal. Close attention to renal function including adequate hydration, urine alkalinization, and measurement of serum methotrexate and creatinine concentrations are essential for safe methotrexate administration.
