What should be avoided for patients taking methylphenidate?

• A. Water
• B. Milk
• C. Vitamin C
• D. Caffeine

Answer: (D)

Both methylphenidate and caffeine are stimulants, so using them together can additively boost brain and sympathetic nervous system activity. This can raise heart rate and blood pressure and worsen side effects like insomnia, anxiety, jitters, and restlessness. To reduce these risks, caffeine-containing products (coffee, tea, energy drinks, colas) should be limited or avoided during methylphenidate treatment. Water, milk, and vitamin C don’t carry the same stimulant interaction and are generally safe options.
