Trihexyphenidyl

About trihexyphenidyl

Trihexyphenidyl is an antimuscarinic medicine. It is prescribed for people who have unwanted movement disorders as a side-effect of taking certain other medicines, such as some antipsychotic medicines. These movement disorders are often referred to as 'extrapyramidal side-effects' and include things like uncontrolled face and body movements, tremor, and restlessness.

Trihexyphenidyl can also be given to relieve muscle stiffness in people with enfermedad de Parkinson, although other medicines are generally preferred.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking trihexyphenidyl it is important that your doctor knows:

• Si estás embarazada, intentando tener un bebé o amamantando.

• If you have any problems with the way your liver works, or the way your kidneys work.

• If you have any problems with your heart or blood vessels.

• If you have prostate problems, or if you have been experiencing difficulty passing urine.

• If you have been constipated for more than a week.

• If you have a condition which causes raised pressure in your eyes, such as glaucoma.

• Si tienes presión arterial alta.

• Si tienes una condición que causa debilidad muscular, llamada miastenia gravis.

• If you have ever had a mental health problem called psychosis.

• Si está tomando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que esté disponible para comprar sin receta, así como medicamentos herbales y complementarios.

• Si alguna vez has tenido una reacción alérgica a un medicamento.

• Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack. It will give you more information about trihexyphenidyl and will provide you with a full list of the side-effects which you may experience from taking it.

• Take trihexyphenidyl exactly as your doctor tells you to. When starting your treatment your doctor will give you a small dose (usually 1 mg daily) and will then gradually increase your dose every few days. Carefully follow the directions your doctor gives to you. Once you are on a full dose, it is likely that you will be taking three doses of trihexyphenidyl a day, although it may be more or less often than this.

• Trihexyphenidyl tablets should be taken with or just after a meal. Try to take your doses at the same times of day each day, as this will help you to remember to take your doses regularly.

• If you forget to take a dose, take it as soon as you remember unless your next dose is due. If it is nearly time for your next dose then take the next dose when it is due but leave out the forgotten dose. Do not take two doses together to make up for a missed dose.
  

• Intenta mantener tus citas regulares con tu médico. Esto es para que tu médico pueda verificar tu progreso.

• If you buy any medicines, check with a pharmacist that they are safe to take with trihexyphenidyl. Some antihistamines and some strong painkillers can interfere with trihexyphenidyl and increase the risk of side-effects.

• If you are having an operation or any dental treatment, tell the person carrying out the treatment that you are taking trihexyphenidyl.

• If you have been taking trihexyphenidyl for some time, do not stop taking it without speaking with your doctor first. Stopping suddenly can cause problems so your doctor will want to reduce your dose gradually if this becomes necessary.

• Ask your doctor for advice before drinking alcohol while you are on trihexyphenidyl. Your doctor may recommend you do not drink alcohol because it increases the possibility of side-effects such as feeling sleepy.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with trihexyphenidyl. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects usually improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

Si experimenta otros síntomas que cree que pueden deberse al medicamento, hable con su médico o farmacéutico para obtener más consejos.

• Mantenga todos los medicamentos fuera del alcance y la vista de los niños.

• Almacenar en un lugar fresco y seco, lejos del calor y la luz directos.
