Effectiveness

How Trihexyphenidyl Hydrochloride Affects PatientsTrihexyphenidyl is used to treat Parkinson's Disease, or to reduce certain effects of medicine on the body. It only needs to be taken occasionally, not every day, and is generally safe to take in large doses. Those taking this medication should have their eye pressure monitored and be aware of the risk of excessive sweating and heat stroke.
How Trihexyphenidyl Hydrochloride works in the bodyTrihexyphenidyl works by blocking receptors in the brain, called muscarinic acetylcholine receptors. These receptors are responsible for sending signals that affect movement. Blocking these receptors helps to reduce the symptoms associated with Parkinson's disease or other movement disorders. Trihexyphenidyl may also increase dopamine release, which helps to further improve movement. The exact way this drug works is not yet fully understood.

This drug stops my tremors which is amazing. The only downside is that it causes a really dry mouth and I have no appetite. Consequently, I've lost 8 pounds since starting the medication 3 months ago.
