It's like having a pharmacist for a best friend
Entacapone belongs to a group of medications called catechol-O-methyl transferase (COMT) inhibitors. It is used along with levodopa-carbidopa or levodopa-benserazide to treat Parkinson's disease.
By inhibiting COMT enzymes that normally break down levodopa in the body, entacapone increases the amount of levodopa reaching the brain. This reduces the end-of-dose "wearing off" effect that some people taking levodopa may experience, thereby minimizing fluctuations in symptoms of Parkinson's disease. When taken on its own, entacapone has no effect on symptoms of Parkinson's disease.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.
Each brownish-orange, oval-shaped film-coated tablet embossed with "EE200" on one side of the tablet and "M" on the other side contains entacapone 200 mg. Nonmedicinal ingredients: hydrogenated vegetable oil, hydroxypropyl cellulose, magnesium stearate, mannitol, and microcrystalline cellulose. Coating: glycerin/glycerol, hydroxypropylmethyl cellulose/hypromellose, iron oxide red, iron oxide yellow, magnesium stearate, polysorbate 80, sucrose, and titanium dioxide.
Entacapone is to be taken together with either levodopa-carbidopa or levodopa-benserazide to treat people with Parkinson's disease who experience end-of-dose "wearing off" of levodopa. End-of-dose "wearing off" refers to a decrease in the amount of time that levodopa is effective, which results in fluctuations in Parkinson's disease symptoms.
The recommended dose of entacapone is 200 mg taken with each levodopa-carbidopa or levodopa-benserazide dose, up to 8 times daily.
This medication can be taken with or without food. Swallow the tablets whole. Do not crush or chew the tablets.
This medication has no effect on symptoms of Parkinson's disease when taken alone.

It is important to take this medication exactly as prescribed by your doctor. If you miss taking a dose of entacapone with your levodopa dose, skip that dose and take your next entacapone dose with your next levodopa dose. Do not take a double dose to make up for a missed one.

Before you begin taking a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should take this medication.
Behavioural and mood changes: This medication may cause mood and psychiatric changes, including hallucinations, hypersexuality, pathological gambling, and increased libido. Tell your doctor as soon as possible if you notice any unusual changes in your behaviour, have thoughts of harming yourself, or feel depressed.
If you have depression or a history of depression, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. If you experience symptoms of depression such as poor concentration, changes in weight, changes in sleep, decreased interest in activities, or notice them in a family member who is taking this medication contact your doctor as soon as possible.
Diarrhea: Diarrhea is a common side effect of this medication. It may appear as early as the first week of starting treatment or many months after starting treatment. For some people, the diarrhea causes weight loss. If you notice any weight loss or have excessive diarrhea, contact your doctor.
Dizziness/reduced alertness: This medication may cause low blood pressure or dizziness and lightheadedness when rising from a lying or sitting position. People taking medications that can cause dizziness should rise slowly from sitting or lying down to reduce the possibility of severe dizziness or fainting. Do not drive, operate machinery, or perform other hazardous tasks until you have determined how this medication affects you.
Fructose intolerance: This medication contains fructose. If you have fructose intolerance, glucose-galactose malabsorption, or sucrase-isomaltase insufficiency, you should not take this medication. Talk to your doctor.
Heart disease: This medication may cause an increase in the risk of heart attack or heart disease. If you have a history of heart disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. This medication is not recommended for people with liver problems.
Melanoma: People with Parkinson's disease may be at increased risk of developing melanoma (a type of skin cancer). It is not known if this increased risk is due to Parkinson's disease or to the medications used to treat Parkinson's disease. Your doctor will monitor you for skin cancer while you are taking this medication. Talk to your doctor if you have any concerns.
Neuroleptic malignant syndrome (NMS): This medication may cause a potentially fatal reaction called neuroleptic malignant syndrome (NMS). If you develop symptoms of NMS, such as muscle stiffness, fever, confusion, sweating, or irregular heartbeat, stop taking this medication and seek immediate medical attention.
Prostate Cancer: A recent study has shown an increase in the number of cases of prostate cancer among men who have taken levodopa/carbidopa with or without entacapone for approximately 3 years. Although it is not clear whether this increased risk of prostate cancer is due to the medication or something else, it is important to have regular prostate examinations while taking medications for Parkinson's Disease.
Rhabdomyolysis (muscle breakdown): Occasionally, this medication may cause rapid breakdown of muscle tissue. If you notice signs of muscle weakness or pain, high body temperature, unexpected bruising, confusion, or difficulty passing urine, contact your doctor immediately.
Stopping this medication: Stopping this medication too quickly can cause potentially life-threatening side effects. Before stopping this medication, discuss the risks and benefits with your doctor. Do not stop taking this medication until you have spoken with your doctor first.
Sudden onset of sleep: There are reports of people who take this combination medication treatment (entacapone with levodopa - carbidopa) falling asleep without prior warning or drowsiness. If you have a sleep disorder, discuss this with your doctor. If you experience drowsiness while taking this medication, avoid driving or using machinery.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
