Entacapone is a medication used to treat symptoms of Parkinson's disease. It belongs to a class of medications known as catechol-O-methyltransferase (COMT) inhibitors that help improve the symptoms of Parkinson's disease, specifically those caused by dopamine deficiency. It is used in combination with the medications levodopa and carbidopa to treat shaking palsy symptoms (commonly referred to as “wearing-off” symptoms) in patients with Parkinson’s.

Entacapone is available under the brand name Comtan and comes in the form of a tablet to take by mouth.

Common side effects of entacapone include:

• Dizziness
  
• Diarrhea
  
• Upset stomach
  
• Movements you cannot control
  
• Stomach pain
  
• Drowsiness
  
• Muscle breakdown
  

This is not a complete list of adverse effects – though these are among the most common. Seek medical attention right away if you experience symptoms such as difficulty breathing, hallucinations, high fever, confusion or muscle stiffness while taking entacapone.

As with all prescription medication, be sure to inform the prescribing doctor about any medical conditions you have been previously diagnosed with, as well as any medication/ supplements you are currently taking before starting treatment with entacapone. Entacapone can interact with other forms of medication and substances, causing potentially serious side effects. In addition, let your doctor know if you are pregnant or plan on becoming pregnant before starting treatment with this medication.

Entacapone comes in the form of a tablet which is typically taken with every dose of levodopa and carbidopa. The dosing frequency will vary depending on your diagnosis, ranging from 1-8 times per day. However, you should take the medication exactly as your healthcare provider prescribes. Do not discontinue or increase your dosage of entacapone without consulting with your provider first. If you begin to experience adverse side effects while taking this medication, like those listed above, inform your provider right away.

Entacapone should be stored in a closed container at room temperature, away from extreme heat, extreme cold, moisture, and direct light, and kept out of the reach of children.

Entacapone is currently only available via prescription. This means a licensed health care provider must authorize the use of this drug.
