The side effects of levodopa may be increased when it is used in combination with entacapone. You may need a dose adjustment if you have been taking levodopa and are starting or stopping treatment with entacapone. Contact your doctor if your condition changes or if you experience movement difficulties, increased drowsiness, dizziness, lightheadedness, flushing, and/or fainting.

Drug and food interactions
levodopa food
Applies to: Stalevo 75 (carbidopa / entacapone / 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.
mephenytoin food
Applies to: mephenytoin
Mephenytoin levels may decrease when the suspension is given with enteral feedings. This could lead to a loss of seizure control. You could interrupt the feeding for 2 hours before and after the mephenytoin dose. Alternatively, you may give the mephenytoin suspension diluted in water and flush the tube with water after administration. These would make it easier for your body to absorb the medication. However, this still may not entirely avoid the interaction and may not always be feasible. You should have your mephenytoin levels checked upon starting and stopping of enteral feedings. In addition, using mephenytoin together with food may alter the effects of mephenytoin. Contact your doctor if you experience worsening of seizure control or symptoms of toxicity, including twitching eye movements, slurred speech, loss of balance, tremor, muscle stiffness or weakness, nausea, vomiting, feeling light-headed, fainting, and slow or shallow breathing. If your doctor does prescribe these medications together, you may need a dose adjustment or special test to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Ask your doctor before making any changes to your therapy.
entacapone food
Applies to: Stalevo 75 (carbidopa / entacapone / levodopa)
Alcohol can increase the nervous system side effects of entacapone 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 entacapone. Do not use more than the recommended dose of entacapone, 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.
levodopa food
Applies to: Stalevo 75 (carbidopa / entacapone / 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.
