Nervous System Home > Trihexyphenidyl Hydrochloride Information

Trihexyphenidyl hydrochloride (Artane®) is a prescription drug approved to treat the following conditions:
  • Parkinson's disease and other similar conditions (when used in combination with other medications)
  • Extrapyramidal disorders (movement or muscle tension disorders) caused by antipsychotic medications.
The medication works by blocking the effects of acetylcholine, a signaling chemical in the nervous system. Nausea, constipation, and dry mouth are some of the most commonly reported side effects. Make sure your healthcare provider has information on your medical history and current medications before taking trihexyphenidyl. This will reduce your risk for serious side effects and drug interactions.
Available in the form of a tablet or an elixir, trihexyphenidyl is usually taken three or four times a day. To keep an even level of the medicine in your blood, take it at the same times each day.
