You will need to answer a few questions about your health before completing purchase of this item.

Irbesartan is a medication that is used to help treat high blood pressure. High blood pressure is also known as hypertension. You are considered to have high blood pressure if you have a reading of 140/90mmHg or above.

140/90mmHg or above belongs to a class of medications known as angiotensin II receptor blockers, also known as ARBs. These medications work by relaxing and widening blood vessels which help to lower blood pressure by making it easier for your heart to pump blood.

You should always take Irbesartan when you have been told to by your healthcare provider. Usually, your doctor may suggest that you take your first dose before bed as it can make you feel dizzy. After your first dose, you should always try to take your medication at the same time every day. 

Your specific dosage of Irbesartan will vary depending on your particular condition. The usual dose for high blood pressure is between 150mg and 300mg a day. If you have liver or kidney problems, or if you are over 75 years of age your dose may be lower. 

Irbesartan is a suitable medication for most adults over the age of 18 years old who need medication to treat high blood pressure. You may be prescribed Irbesartan if you have previously taken other blood pressure medications that have given you side effects.

Irbesartan may not be a suitable medication for some people. This medication should not be used by anyone who is allergic to any of the ingredients in the product. This medication should also not be used by children. You should not use Irbesartan if:

  • You have diabetes
  • You have heart or kidney issues
  • You have had a kidney transplant
  • You have recently been sick or had diarrhoea
  • You are on a low-salt diet
  • You have low blood pressure

No, you should not use Irbesartan during pregnancy, or whilst you are trying to become pregnant. The medication can reduce the level of fluid that surrounds your baby which can result in long-term kidney or lung damage. Your doctor may prescribe you this medication during early pregnancy, however, it must be stopped by the 12th week of pregnancy.

No, Irbesartan may not be suitable for use during breastfeeding. There is little evidence that suggests it can be used whilst breastfeeding, however, you should consult with your doctor to discuss your treatment.

Irbesartan may interact with some other medications. You need to let your doctor know about any medications you are using, or any medications you have taken. Let your doctor know if:

  • You are using other blood pressure medicines
  • You are using painkillers such as ibuprofen, naproxen, diclofenac
  • You are using heparin
  • You are using medications to make you urinate more
  • You are using lithium

  • Dizziness
  • Headaches
  • Feeling sick or nauseous
  • Being sick
  • Diarrhoea
  • Pain in the muscles and joints
