AVOIDING CERTAIN FOODS WHILE TAKING LEVODOPA

If your patient with parkinsonism is taking levodopa, he must be careful to avoid vitamin B6 (pyridoxine) because it may interfere with the therapeutic effects of the drug.

Vitamin B6 is also found in a wide variety of food sources. It may be impossible to ask the patient to avoid these food sources entirely, but your patient may need to limit or decrease such intake to enhance or maintain the drug's effectiveness.
