Without a Prescription
Entacapone is prescribed for Parkinson's disease.
Entacapone works by inhibiting the effect of an enzyme that breaks down the levodopa in Sinemet.
By extending the effect of each dose of Sinemet, it frees the patient from the stiffness and tremors of Parkinson's for a longer period of time.
It has no effect on Parkinson's disease when prescribed by itself.
It is prescribed when doses of the combination drug levodopa/carbidopa (Sinemet) begin to wear off too soon.
Entacapone side effects that you should report to your health care professional or doctor as soon as possible:
- Tired feeling;
- Onset of new movement disorders;
- Discoloration of urine;
- Back pain;
- Abdominal pain;
If you were taking more than 800 mg of levodopa per day before starting Entacapone, you will probably need a reduction in your levodopa dose once you begin taking the drug.
The recommended dose is one 200-mg tablet with each dose of Sinemet, up to a maximum of 8 doses per day.
