About irbesartan

Irbesartan is an angiotensin receptor blocker. It is also called an angiotensin-II receptor antagonist, or an AIIRA. It is used to treat pressão alta (hipertensão). People with high blood pressure usually do not feel unwell, but if left untreated, high blood pressure can harm the heart and damage blood vessels.

Irbesartan works by blocking the effect of a chemical called angiotensin II. Angiotensin II causes your blood vessels to narrow, so by blocking its effect, irbesartan allows your blood vessels to relax and widen. As this happens, the pressure within your blood vessels is reduced. Irbesartan also has a protective function on the kidneys of people with type 2 diabetes who have high blood pressure.

Irbesartan may be prescribed on its own to treat high blood pressure, or you may also be given other medicines to take alongside it. This is because a combination of medicines which work in different ways can often lower your blood pressure more than one medicine on its own. One brand of tablet called CoAprovel® contains hydrochlorothiazide as well as irbesartan - being prescribed a combination brand like this will help to reduce the number of tablets you need to take each day.

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 irbesartan it is important that your doctor knows:

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

• If you have a problem with your kidneys, particularly if it is a blockage of the artery which supplies blood to your kidneys.

• Se você tem diabetes mellitus.

• Se você tiver algum problema com suas válvulas cardíacas ou músculo cardíaco.

• 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.

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

• Take irbesartan once each day, exactly as your doctor tells you to. There are several different strengths of tablet available (75 mg, 150 mg and 300 mg) - your doctor will tell you which strength of tablet is right for you.

• Try to take irbesartan at the same time of day each day. This will help you to remember to take your doses regularly.

• Swallow the tablet with a drink of water. You can take irbesartan before or after meals.

• Se você esquecer de tomar uma dose, tome-a assim que se lembrar. Se não se lembrar até o dia seguinte, pule a dose esquecida. Não tome duas doses ao mesmo tempo para compensar uma dose esquecida.

• Try to keep your regular appointments with your doctor. This is so your progress can be monitored and your blood pressure measured. Your doctor may want you to have some blood tests from time to time to check on your kidneys, and also on how much potassium is in your blood.

• Cada vez que você retirar uma receita, verifique se ela possui a dosagem de comprimido que você espera.

• If you buy any medicines, check with a pharmacist that they are suitable to take with irbesartan. This is because some anti-inflammatory painkillers (such as aspirin and ibuprofen) may interfere with the way it works, and also may increase the risk of side-effects.

• É muito importante que você siga quaisquer orientações dietéticas e de estilo de vida que seu médico possa ter lhe dado, como manter uma alimentação saudável, não fumar e praticar exercícios regularmente.

• If you drink alcohol, ask your doctor for advice. Your doctor may recommend that you do not drink alcohol while you are on irbesartan because it will increase the risk of side-effects, such as feeling dizzy or faint.

• Procure evitar substitutos de sal que contenham potássio. Isso porque os substitutos podem aumentar a quantidade de potássio no seu sangue, o que pode causar problemas.

• If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking irbesartan. This is because your blood pressure may drop too low if you are given some anaesthetics.

• Treatment with irbesartan is usually long-term unless you experience an adverse effect. Continue to take the tablets regularly, unless you are advised otherwise by your doctor.

Se você também estiver tomando hidroclorotiazida em combinação com este medicamento

• Estudos sugerem que tomar doses mais altas de hidroclorotiazida por longos períodos de tempo pode aumentar o risco de certos tipos de câncer de pele.

• Informe o seu médico se você já foi tratado para câncer de pele antes.

• Informe seu médico sobre qualquer nova pinta ou alteração em pintas existentes, ou marcas preocupantes na sua pele.

• Use protetor solar sob luz solar intensa. Não use camas de bronzeamento.

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 irbesartan. 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.

• Mantenha todos os medicamentos fora do alcance e da vista das crianças.

• Armazene em local fresco e seco, longe de calor e luz diretos.
