Nov 30 2009Q:
My father is taking levadopa and carbidopa four times a day. I read that vitamin B5 (pantothenic acid) and vitamin B6 (pyridoxine) can interfere with those drugs. Is this true? Is there a certain dosage of these vitamins that are okay? Can you recommend a daily vitamin supplement for someone taking Levodopa /Carbidopa that still includes the other B vitamins? (LH)
Vitamin B6 was originally a problem for those taking plain levodopa but once the carbidopa was added, these interaction problems were resolved. Therefore, it is no longer problematic to take B6 with antiparkinsonian drugs. Vitamin B5 does not interfere with these drugs either. In general, if a multi-vitamin is needed or the patient believes in such therapy, any good multi-vitamin can be used.
