Trihexifenidil

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 medicamentos antipsicóticos. 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 Doença de Parkinson, although other medicines are generally preferred.

Before taking trihexyphenidyl

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:

• Se você está grávida, tentando ter um bebê ou amamentando.

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

• Se você tiver algum problema com o coração ou vasos sanguíneos.

• 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.

• Se você tem pressão alta.

• Se você tem uma condição que causa fraqueza muscular, chamada miastenia gravis.

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

• Se você estiver tomando outros medicamentos. Isso inclui quaisquer medicamentos que você esteja tomando e que estejam disponíveis para compra sem receita médica, bem como medicamentos fitoterápicos e complementares.

• Se você já teve uma reação alérgica a um medicamento.

How to take trihexyphenidyl

• 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.
  

Obtendo o máximo do seu tratamento

• Tente manter suas consultas regulares com seu médico. Isso é para que seu médico possa verificar seu progresso.

• 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.
