What is trihexyphenidyl hydrochloride used for?
Trihexyphenidyl hydrochloride tablets are used to treat symptoms caused by certain movement disorders, especially those involving muscle stiffness and involuntary movements. It works by helping reduce abnormal nerve signals that lead to these motor symptoms. [1]
Which conditions does it treat?
It is commonly prescribed for symptoms related to:
- Parkinson’s disease (to help with tremor, stiffness, and slow movement symptoms) [1]
- Drug-induced movement disorders (when medicines cause stiffness, tremor, or other extrapyramidal symptoms) [1]
How is it usually taken for movement symptom control?
The goal is symptom relief rather than cure, so dosing is adjusted to improve control of stiffness/tremor while limiting side effects. Patients typically take it by mouth as directed by a clinician. [1]
What side effects do people commonly notice?
Because trihexyphenidyl has anticholinergic effects, common side effects can include dry mouth, constipation, blurred vision, and trouble urinating. Tell a clinician if side effects are severe or worsening. [1]
Who should be cautious or ask a clinician first?
People with certain conditions (for example, problems with urine flow, severe constipation, or narrow-angle glaucoma) may need extra caution with anticholinergic medicines like trihexyphenidyl. A clinician can assess safety for your situation. [1]
