3. HOW TO TAKE TRIHEXYPHENIDYL TABLETS
Always take Trihexyphenidyl Tablets exactly as your doctor has told you to. The label on your medicine should also tell you. You should check with your doctor or pharmacist if you are not sure.
The dose of trihexyphenidyl varies from person to person depending on the symptoms. You will normally start on a low dose and this may be increased gradually by your doctor. The usual dose is between 5 - 15 mg per day (each tablet contains either 2mg or 5mg). Some people may need less, especially if they are also taking other medicines. Also, if you are over 65 years of age, you may need less than the usual dose.
Trihexyphenidyl Tablets should be taken at meal times (just before or just after a meal). If you are not sure how many tablets to take or when to take them, ask your pharmacist. Trihexyphenidyl Tablets should be swallowed whole with a glass of water.
If you take more Trihexyphenidyl Tablets than you should
If you have taken an overdose of Trihexyphenidyl Tablets (that is more than the doctor has told you to) get medical help immediately, either by calling your doctor or going to the nearest hospital casualty department. Remember to take the labelled medicine bottle with you, whether there are any Trihexyphenidyl Tablets left or not.
If you forget to take Trihexyphenidyl Tablets
If you forget to take a tablet you should take it as soon as you remember. However, if this is within 2 hours of your next dose you should skip the missed tablet and carry on taking the rest of your tablets as usual.
Do not take a double dose to make up for the forgotten tablet.
If you stop taking Trihexyphenidyl Tablets
Do not stop taking this medicine suddenly as your symptoms may get worse. If your dose needs to be lowered, your doctor will reduce the amount you should take gradually.
