Trihexyphenidyl How to Take

Trihexyphenidyl belongs to the family of medications called antiparkinsonians. It is used to treat symptoms of Parkinson's Disease. It may also be used to reduce the shakiness and restlessness that can be caused by some tranquilizers. It acts on the nervous system and corrects some of the chemical imbalances that cause Parkinson's disease as well as the symptoms caused by some medications.

Your doctor may have suggested Trihexyphenidyl for conditions other than those listed in these drug information articles. As well, some forms of Trihexyphenidyl may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are taking Trihexyphenidyl, speak to your doctor. Do not stop taking Trihexyphenidyl without consulting your doctor.

Do not give Trihexyphenidyl to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take Trihexyphenidyl if their doctor has not prescribed it.

Trihexyphenidyl Dosage

For treatment of Parkinson's disease, the recommended dose of trihexyphenidyl starts with 1 mg the first day and then increases by 2 mg daily at intervals of 3 to 5 days until symptoms are controlled. The usual daily dose ranges from 6 mg to 10 mg daily depending on needs (taken in divided doses at mealtimes).

The dose needed for medication-induced symptoms varies widely according to the particular medication and dose that are causing the symptoms.

Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

It is important to take Trihexyphenidyl exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store Trihexyphenidyl at room temperature, protect it from light and moisture, and keep it out of the reach of children.
