All to know


Krka, D.D., Novo Mesto

What is it and how is it used?

Ifirmasta belongs to a group of medicines known as angiotensin-II receptor antagonists. Angiotensin-II is a substance produced in the body which binds to receptors in blood vessels causing them to tighten. This results in an increase in blood pressure. Ifirmasta prevents the binding of angiotensin-II to these receptors, causing the blood vessels to relax and the blood pressure to lower. Ifirmasta slows the decrease of kidney function in patients with high blood pressure and type 2 diabetes.

Ifirmasta is used

  • to treat high blood pressure ( essential hypertension)
  • to protect the kidney in patients with high blood pressure, type 2 diabetes and laboratory evidence of impaired kidney function.


What do you have to consider before using it?

Do not take Ifirmasta

  • if you are allergic (hypersensitive) to irbesartan or any of the other ingredients of Ifirmasta,
  • if you are more than 3 months pregnant. (It is also better to avoid Ifirmasta in early pregnancy ? see pregnancy section)

Ifirmasta should not be given to children and adolescents (< 18 years)

Take special care with Ifirmasta

Tell your doctor if any of the following aply to you:

  • if you get excessive vomiting or diarrhoea,
  • if you suffer from kidney problems
  • if you suffer from heart problems,
  • if you receive Ifirmasta for diabetic kidney disease. In this case your doctor may perform regular blood tests, especially for measuring blood potassium levels in case of poor kidney function,
  • if you are going to have an operation (surgery) or be given anaesthetics.

You must tell your doctor if you think you are ( or might become) pregnant. Ifirmasta is not recommended in early pregnancy, and must not be taken if you are more than 3 months pregnant, as it may cause serious harm to your baby if used at that stage (see pregnancy section).

Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

Ifirmasta does not usually interact with other medicines.
Blood tests may be neccessary if you take:

  • potassium supplements,
  • potassium-containing salt substitutes,
  • potassium-sparing medicines that increase the amount of urine (diuretics) or
  • lithium-containing medicines.

As with other blood pressure lowering medicinal products, the effect of irbesartan may be reduced when you take non-steroidal anti-inflammatory medicinal products (for example, ibuprofen).

Taking Ifirmastawith food and drink
Ifirmasta can be taken with or without food. The tablets should be swallowed with a drink of water.

Pregnancy and breast-feeding

Ask your doctor or pharmacist for advice before taking any medicine.


You must tell your doctor if you think you are ( or might become) pregnant. Your doctor will normally advise you to stop taking Ifirmasta before you become pregnant or as soon as you know you are pregnant and will advise you to take another medicine instead of Ifirmasta. Ifirmasta is not recommended in early pregnancy, and must not be taken when more than 3 months pregnant, as it may cause serious harm to your baby if used after the third month of pregnancy.


Tell your doctor if you are breast-feeding or about to start breast-feeding. Ifirmasta is not recommended for mothers who are breast-feeding, and your doctor may choose another treatment for you if you wish to breast-feed, especially if your baby is newborn, or was born prematurely.

Driving and using machines
Ifirmasta is unlikely to affect your ability to drive or use machines. However, occasionally dizziness or tiredness may occur during treatment of high blood pressure. If you experience these symptoms, you should consult your doctor before driving or using machines.

In patients with high blood pressure and type 2 diabetes with renal disease, dizziness when getting up from a lying or sitting position, low blood pressure when getting up from a lying or sitting position, pain in joints or muscles and decreased levels of a protein in the red blood cells (haemoglobin) were also reported.
