Drug Interactions With Carbidopa-Levodopa-Entacapone
Metoclopramide can make carbidopa-levodopa-entacapone less effective. However, metoclopramide may also increase the absorption of carbidopa-levodopa-entacapone into the body, which could make it more effective or increase the risk of carbidopa-levodopa-entacapone side effects. It is difficult to predict what exactly may happen if these medications are combined. Check with your healthcare provider before taking these medications together.
Monoamine Oxidase Inhibitors (MAOIs)
Non-selective MAOIs (isocarboxazid, phenelzine, and tranylcypromine) should not be combined with carbidopa-levodopa-entacapone. Selective MAOI-B inhibitors (selegiline and rasagiline) can be used with carbidopa-levodopa-entacapone, although the risk of low blood pressure may be increased.
Phenytoin (Dilantin, Phenytek)
Phenytoin can make carbidopa-levodopa-entacapone less effective. Check with your healthcare provider before taking these medications together.
Probenecid may affect the level of entacapone (one of the components of carbidopa-levodopa-entacapone) in your blood. Check with your healthcare provider before taking these medications together.
There have been reports of occasional problems, such as high blood pressure or involuntary body movements, when a tricyclic antidepressant was combined with carbidopa-levodopa (two of the components of carbidopa-levodopa-entacapone). Check with your healthcare provider before combining carbidopa-levodopa-entacapone with a tricyclic antidepressant.
