Correct answer: A — Do not dispense until the weekly dose and day are clarified
Methotrexate for rheumatoid arthritis is a high-risk medicine taken once weekly, and daily dosing errors can be fatal. The prescription must state clear dose instructions before supply. The patient should receive counselling on weekly dosing, folic acid, toxicity symptoms and monitoring. Unclear directions are unsafe.
