Levodopa/carbidopa (Sinemet) can interact with multivitamins that contain vitamin B6, which can reduce the effectiveness of the medication. Therefore, the nurse should instruct the client not to take the multivitamin with the levodopa/carbidopa (Sinemet). The antihistamine and aspirin do not have significant interactions with levodopa/carbidopa (Sinemet). However, it is always important for the client to inform their healthcare provider of any medication, supplement, or herbal products they are taking.
