When should methotrexate be taken for best tolerability?

• A. On an empty stomach
• B. With a high-fat meal
• C. With breakfast
• D. At bedtime

Answer: (A)

The timing of methotrexate affects how it is absorbed and tolerated. Taking methotrexate on an empty stomach leads to more predictable, rapid absorption with less variability from food in the gut. When food is present, especially fatty meals, absorption can be slower and more variable, which can increase gastrointestinal irritation and inconsistent drug exposure, making tolerability worse. Therefore, for best tolerability, methotrexate is taken on an empty stomach with a full glass of water. (Note: folic acid supplementation is often used to reduce mucosal toxicity, but the question here focuses on meal timing.)
