Irbesartan
About Irbesartan
Irbesartan belongs to a group of medicines known as angiotensin II receptor blockers indicated for the treatment of hypertension (high blood pressure) in adults. Additionally, Irbesartan is used to reduce the risk of heart attack or stroke in adults. Hypertension is a medical condition in which the blood pressure is elevated persistently in the arteries without any known cause. On the other hand, heart attack or stroke occurs due to blocked blood flow to the heart or brain, respectively.
Irbesartan works by blocking the action of a hormone called angiotensin II in the body, which causes the narrowing of blood vessels, leading to high blood pressure. Thereby, Irbesartan widens and relaxes blood vessels, lowering high blood pressure.
You can take Irbesartan irrespective of food and swallow it whole with a glass of water. Do not crush, chew, or break it. Your doctor will let you how often you should take your tablets based on your medical condition. In some cases, you may experience nausea, vomiting, fatigue, and orthostatic hypotension. Most of these side effects of Irbesartan do not require medical attention and gradually resolve over time. However, if the side effects persist, please consult your doctor.
Irbesartan is not for pregnant women as its use during your pregnancy can cause injury and even death to your unborn baby. It is not known whether Irbesartan passes into your breast milk or not. Your doctor will decide if you will take Irbesartan while using Irbesartan and breastfeeding together. Prolonged intake of Irbesartan may cause high potassium in the blood (hyperkalemia). Avoid intake of potassium supplements with Irbesartan as it may lead to high potassium levels in the blood, so the doctor may ask you to have a regular check of your potassium level. Do not consume alcohol with Irbesartan as it may increase the risk of low blood pressure. Taking Irbesartan with painkillers (like aspirin and ibuprofen) can increase the risk of kidney problems and reduce the efficiency of Irbesartan.

Safety Advice
Alcohol
cautionNot recommended. Irbesartan and alcohol together result in an abnormal decrease in blood pressure levels, thus strictly not to be taken together.
Pregnancy
unsafeNot recommended in pregnant patients. Irbesartan is harmful to an unborn baby, especially in the first 3 months of pregnancy. Irbesartan is to be replaced with any other blood pressure-lowering drug on doctor consultation.
Breast Feeding
cautionNot recommended in breastfeeding patients. Enough data is not available on the usage of Irbesartan in breastfeeding mothers; thus, it is replaced with any alternative blood pressure-lowering agents in doctors' consultations.
Driving
safe if prescribedIrbesartan is unlikely to affect your ability to drive or use heavy machines. However, occasionally, dizziness or slowness of movements may occur during the treatment of high blood pressure. If you experience these, talk to your doctor before attempting such activities.

Patients Concern
Disease/Condition Glossary

This results in the damage of the blood vessels. If high blood pressure is left untreated, it can lead to stroke, heart attack, heart failure, kidney failure, and eye problems.

Only on doctors consultation, a patient can take Irbesartan with metformin which has been found to have a beneficial effect on kidneys in a diabetic patient with hypertension.
