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 is what is known as a selective angiotensin II subtype 1 receptor antagonist. This class of medication works by blocking angiotensin II AT1 receptors which bind with the hormone angiotensin II. Once these receptors have been blocked, the blood vessels widen in a process known as vasodilation which in turn helps to lower blood pressure. 

How does it work? – Irbesartan is the active ingredient in the drug and is responsible for preventing angiotensin II from binding to the angiotensin II AT1 receptors. Angiotensin II works on the central nervous system and helps to regulate renal function and renal nerve activity. As a direct result, angiotensin II has a key role in the regulation of blood pressure. Irbesartan is available in tablet form only and you must have a prescription to use it.

How to take Irbesartan tablets – Irbesartan is available in oral tablet form. You will 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 Irbesartan can make you feel dizzy when you first take it. Once you have taken the first dose you will 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 is used to treat high blood pressure rather than prevent it. You will normally take the medication long-term, if not for the rest of your life. Once you have been taking Irbesartan for a few weeks, your doctor will check your blood pressure and ask if you have 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 are 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 are considering switching from another medication to Irbesartan or vice-versa, then you need to speak to your doctor first.

Is is 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.

These may have caused side effects or a dry cough which may have meant you had to stop taking them.
