Benztropine

Cogentin™

What It's For & How To Take

Benztropine is used to treat the tremors associated with Parkinson’s disease. This medication is also used to help treat the involuntary movements caused by side effects from the use of anti-psychotic medications. Benztropine works by blocking the effects of a natural chemical in the body. Blocking this chemical decreases muscle stiffness and may help to decrease muscle spasms, twitches, and tremors.

Even though benztropine may be helpful in treating the Parkinson-like symptoms caused by antipsychotic medications, this medication is not to be used to treat a muscle condition known as tardive dyskinesia. Tardive dyskinesia is a long-term muscle movement condition and treatment with benztropine may make it worse.

This medication is usually taken as a single dose at bedtime or may be prescribed to be taken up to 4 times daily as directed by your doctor. Your doctor may start benztropine at a small dose and gradually increase the dose over a few days or weeks to get the best dose for your condition. It may take up to 3 days before you notice the benefit of this medication.

If you miss a dose, take it as soon as you remember. If it is near the time of your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.

Take benztropine at least 2 hours before or 6 hours after vitamins or antacids such as Tums™ or Mylanta™. Some foods high in calcium such as yogurt or milk may also block this medication from working. Ask your pharmacist what you can and can’t have with this medication.

If you have taken benztropine on a regular basis for an extended period of time, you may find that the medication may not work as well. Notify your doctor if you notice that this medication is not controlling your symptoms as well as it did when you first started taking it.

Do not stop taking benztropine abruptly without talking to your doctor. If this medication is stopped abruptly, the Parkinson-like symptoms may quickly return.
