TRIHEXYPHENIDYL
About
TRIHEXYPHENIDYL is used as an adjunct to treat Parkinson’s disease and extrapyramidal symptoms (drug-induced movement disorders). Parkinson’s disease is a progressive neurological disorder in which the first signs are problems with movements.
TRIHEXYPHENIDYL contains ‘Trihexyphenidyl’, which works by relaxing the muscles and nerve impulses that control muscle functioning. Besides this, TRIHEXYPHENIDYL also balances chemical messengers called neurotransmitters in the brain, thereby improving muscle control and reducing stiffness, thereby helping the muscles move naturally.
In some cases, you may experience common side effects such as nausea, vomiting, dizziness, constipation, weakness, headache, dry mouth, decreased urination, drowsiness, and feeling nervous or restless. Most of these side effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if the side effects persist or worsen.
Consult your doctor if you are pregnant or breastfeeding. TRIHEXYPHENIDYL may cause drowsiness and dizziness; do not drive unless you are alert. TRIHEXYPHENIDYL should not be given to children as safety and effectiveness have not been established. Avoid consuming alcohol along with TRIHEXYPHENIDYL as it could lead to increased drowsiness and dizziness. Keep your doctor informed about your medicines and health conditions to rule out any side effects.
Uses of TRIHEXYPHENIDYL
Medicinal Benefits
TRIHEXYPHENIDYL belongs to a group of medicines called anti-spasmodic agents. TRIHEXYPHENIDYL is used to treat the symptoms of Parkinson’s disease and extrapyramidal symptoms (drug-induced movement disorders). TRIHEXYPHENIDYL exerts a direct inhibitory effect upon the parasympathetic nervous system. It works by relaxing the muscles and nerve impulses that control muscle functioning. TRIHEXYPHENIDYL improves muscle control and reduces stiffness, thereby helping the muscles move naturally. TRIHEXYPHENIDYL is used as an adjuvant therapy along with levodopa to treat Parkinson's disease. Additionally, TRIHEXYPHENIDYL is used to control drug-induced movement disorders caused by CNS drugs such as dibenzoxazepines, thioxanthenes, phenothiazines, and butyrophenones.

Habit Forming
Diet & Lifestyle Advise
- Maintain a healthy diet and exercise regularly.
- Include a diet rich in iron, folate and magnesium.
- Regularly attend therapy sessions.

Special Advise
Take TRIHEXYPHENIDYL at least 2 hours after taking ketoconazole and antidiarrheal medicines as it may prevent the full absorption of trihexyphenidyl. Besides this, TRIHEXYPHENIDYL may prevent the complete absorption of antifungal agents like ketoconazole when these medicines are taken together.
TRIHEXYPHENIDYL can cause decreased sweating, resulting in a rise in body temperature (hyperthermia). This profound side effect is more significant in hot weather, so it is advisable to drink plenty of water, especially in summer. However, kidney patients should consult a doctor before consuming any fluid.
Take special care with your dental hygiene while using TRIHEXYPHENIDYL (like brushing, and flossing) and have regular dental check-ups.
Patients Concern
Disease/Condition Glossary
Parkinson’s disease: It is a progressive neurological disorder in which the first signs are problems with movements. Dopamine is a naturally occurring neurotransmitter in the brain which is reduced or absent in people with Parkinson’s disease. Due to this, problems arise with smooth and coordinated movements. Symptoms include decreased ability to smell, stooped posture, changes in voice, constipation, small/ cramped handwriting, tremors, slow movements, stiffness of arms, legs, trunk, and balance problems.
