Trihexyphenidyl, while effective for treating Parkinson’s disease symptoms and dystonia, can cause various side effects. These vary in severity and frequency, depending on the individual and dosage.
Common side effects include dry mouth, blurred vision, constipation, and urinary retention. These usually lessen as your body adjusts to the medication. Drink plenty of fluids to combat dry mouth and consider dietary changes to alleviate constipation. If urinary retention becomes problematic, consult your doctor immediately.
Less common, but still possible, are more serious adverse reactions. These include:
| Neuroleptic malignant syndrome (NMS) | High fever, muscle rigidity, altered mental state | Seek immediate medical attention. This is a life-threatening condition. |
| Increased intraocular pressure (glaucoma) | Severe eye pain, blurred vision, halos around lights | Contact your ophthalmologist or doctor immediately. |
| Tachycardia (rapid heartbeat) | Rapid pulse, palpitations | Inform your doctor, especially if you have pre-existing heart conditions. |
| Allergic reactions | Rash, hives, itching, swelling | Stop taking the medication and seek medical help. |
| Psychosis | Hallucinations, delusions, confusion | Contact your doctor; dosage adjustment or alternative medication may be necessary. |
