Comprimidos de Pizotifeno

About pizotifen

Pizotifen is taken to prevent troublesome headaches such as enxaqueca and recurrent throbbing headaches. It is also used to treat cluster headaches. These are headaches which occur in close succession at certain times of the year, usually lasting 6-12 weeks.

Your body produces chemicals which, in some cases, may be involved in causing headaches. These chemicals are 'serotonin', 'tryptamine' and 'histamine'. Pizotifen helps to stop the effect of these chemicals.

Pizotifen must be taken every day to help stop migraine attacks from starting. It may not completely stop every migraine attack, but the number and severity of your attacks should reduce. Although it can help to reduce the number of attacks you have, it is not effective in relieving a migraine attack that has already started.

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

• Se você está grávida ou amamentando.

• If you have increased pressure in your eye, a condition called glaucoma.

• If you have been experiencing difficulty passing urine.

• If you have ever had fits or epilepsy.

• Se você tiver algum problema com o funcionamento do seu fígado, ou se tiver algum problema com o funcionamento dos seus rins.

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

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

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

• Take the tablets exactly as your doctor tells you to. You will find the directions for taking the tablets on the label of the pack to remind you about what the doctor said to you. There are two strengths of tablet: 500 micrograms and 1.5 mg. It is usual to begin by taking one 500 microgram tablet a day at bedtime. Your dose may then be gradually increased to the usual maintenance dose of 1.5 mg daily (taken as one single daily dose at bedtime, or divided into three smaller doses).

• Swallow the tablet with a drink of water. Try to take your doses at the same time(s) of day each day, as this will help you to remember to take pizotifen regularly. You can take the tablet either with or without food.

• Se você esquecer de tomar uma dose no horário habitual, tome-a assim que se lembrar (a menos que esteja quase na hora da próxima dose, nesse caso, pule a dose esquecida e tome a próxima dose normalmente). Não tome duas doses juntas para compensar uma dose esquecida.
  

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

• For some people there may be things which trigger an attack. These can include some foods (for example, cheese, chocolate, and red wine), worry, bright sunlight, too much or too little sleep, and skipping meals. Try to avoid things that you suspect trigger your headaches.

• Pizotifen can cause sleepiness. Your doctor may recommend that you do not drink alcohol while you are taking the tablets, as alcohol will increase the drowsiness.

• It is unlikely that pizotifen will stop your headaches completely. You may find it useful to keep a migraine diary to monitor how well it is working. Note down when and where each attack started, what you were doing, and what you had eaten that day. A pattern may emerge and it may be possible for you to avoid some of the things that trigger your attacks.

• If a migraine attack occurs despite taking pizotifen, you can still take painkillers or a triptan medicine to ease the pain and sickness.

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 pizotifen. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often 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.

Se você sentir quaisquer outros sintomas que acha que podem ser causados pelos comprimidos, fale com seu médico ou farmacêutico para mais orientações.
