Irbesartan Tablets

What kind of medication is it? – irbesartan is a medicine which is widely used for the treatment of high blood pressure, also known as hypertension. It works by stopping a hormone called angiotensin II from working. This means that the muscles in your blood vessels relax, which in turn helps to lower blood pressure.

How to take irbesartan tablets – irbesartan is available in oral tablet form. You’ll only take irbesartan once per day and your doctor may suggest you take your first dose before you go to bed. The reason for this is that irbesartan can make you feel dizzy when you first take it. Once you’ve taken the first dose you’ll be able to take it at any time of the day. However, you should aim to take it at the same time every day.

Getting check ups – it’s used to treat high blood pressure rather than prevent it. You’ll normally take the medication long-term, if not for the rest of your life. Once you’ve been taking irbesartan for a few weeks, your doctor will check your blood pressure and ask if you’ve experienced any side effects. They may also request a blood test to see how well your kidneys are working and check your blood potassium levels. The information they gather from the tests will help them to decide whether they need to change your dose.

When you might need a different dosage – if you’re still experiencing high blood pressure, then the dose you take may be increased. Equally, if your blood pressure becomes too low or you’re experiencing side effects, then your doctor may decide to lower your dose of irbesartan.

It is if your doctor has prescribed it to you – as irbesartan is only available on prescription, your doctor should have already approved its use. Therefore, you should be a suitable candidate for irbesartan treatment. However, if you’re considering switching from another medication to irbesartan or vice-versa, then you need to speak to your doctor first.

It’s a common, effective treatment – irbesartan is a well-established angiotensin II receptor blocker and is used all over the world as a treatment for high blood pressure. You may have been prescribed irbesartan if you’ve already tried other blood pressure medications called angiotensin-converting enzyme (ACE) inhibitors such as ramipril and lisinopril. These may have caused side effects or a dry cough which may have meant you had to stop taking them.

Irbesartan is not for everyone – irbesartan is usually prescribed to adults over the age of 18, but it’s not suitable for everyone. For example, you may not be able to take irbesartan if you:
