Drug and food interactions
levodopa food
Applies to: carbidopa / levodopa
Alcohol can increase the nervous system side effects of levodopa such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with levodopa. You may experience reduced effectiveness of levodopa in the presence of foods or enteral (tube) feedings with a high protein content. This may make the symptoms of Parkinson's disease worse. Talk with your doctor or nutrition counselor about the best foods to eat while you are taking this medication. Contact your doctor if your condition changes.
gabapentin food
Applies to: gabapentin
Alcohol can increase the nervous system side effects of gabapentin such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with gabapentin. Do not use more than the recommended dose of gabapentin, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.
pramipexole food
Applies to: Mirapex (pramipexole)
Alcohol can increase the nervous system side effects of pramipexole such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with pramipexole. Do not use more than the recommended dose of pramipexole, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.
rasagiline food
Applies to: Azilect (rasagiline)
Rasagiline may be taken with or without food. There is no need to avoid most foods and beverages during treatment with rasagiline, as long as you are not receiving more than 1 mg per day of the medication. However, certain foods such as some of the aged cheeses (for example, Boursault, Liederkrantz, Mycella, and Stilton) may contain very high amounts of tyramine and should generally be avoided if possible. Consumption of very high levels of tyramine (greater than 150 mg) while on rasagiline treatment may lead to dangerous increases in your blood pressure, a condition known as hypertensive crisis. Talk to your doctor or pharmacist if you are uncertain about what foods, if any, to avoid. You should seek immediate medical attention if you experience sudden and severe headache, blurred vision, confusion, seizures, chest pain, nausea or vomiting, sudden numbness or weakness (especially on one side of the body), speech difficulties, fever, sweating, lightheadedness, and/or fainting during treatment with rasagiline, as these may be signs and symptoms of a hypertensive crisis. It is important to tell your doctor about all other medications you use, including vitamins and herbs, since some medications may increase the blood levels of rasagiline and possibly lead to interactions with tyramine-rich foods. Do not stop using any medications without first talking to your doctor.
levodopa food
Applies to: carbidopa / levodopa
Levodopa and multivitamin with minerals should not be taken orally at the same time. Products that contain iron may interfere with the absorption of levodopa and reduce its effectiveness. You should separate the dosing of these medications by as much as possible. Contact your doctor if your Parkinson symptoms worsen. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
