Sometimes when a doctor prescribes a medicine for you or someone in your family, you wonder what it is, what it does, and what precautions you should take. Today we are going to talk about a medicine that is important to many people. It is Trihexyphenidyl. You may know it by the brand name `Artane`.
What is this medicine used for?
Simply put, this medicine is mainly used in two situations.
1. Parkinsonism: This is a brain disorder that causes tremors, stiffness, and slow movements. Trihexyphenidyl helps control these symptoms.
2. Movement problems caused by other medications: Some medications used for mental illnesses can also cause movement problems similar to Parkinson's disease in some people. This medicine is also used in such cases.
The most important thing is that this medicine should only be used under the advice of a doctor. Never use this medicine just because you think it will help you or because someone else thinks it will help you.
