Eprosartan is an angiotensin receptor blocker (also called an angiotensin-II receptor antagonist (AIIRA)). It is used to treat hypertension (high blood pressure). People with high blood pressure often do not feel unwell but, left untreated, high blood pressure can harm the heart and damage blood vessels.

Eprosartan works by blocking the effect of a chemical called angiotensin II which is made in your bloodstream. Angiotensin II causes your blood vessels to narrow, so by blocking this effect, eprosartan allows your blood vessels to relax and widen. As this happens, the pressure within your blood vessels is reduced. This also makes it easier for your heart to pump blood around your body.

Eprosartan may be prescribed on its own to treat high blood pressure, or you may also be given another medicine to take alongside it. This is because a combination of medicines which work in different ways can lower your blood pressure more than one on its own.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking eprosartan it is important that your doctor or pharmacist knows: 

  • If you are pregnant, trying for a baby or breast-feeding.
  • If you have kidney problems such as a blockage of the artery which supplies blood to your kidney.
  • If you have liver problems.
  • If you have any problems with your heart valves or heart muscle.
  • If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, such as herbal and complementary medicines.
  • If you have ever had an allergic reaction to a medicine.
  • Before you start this treatment, read the manufacturer's printed information leaflet from inside the pack. The leaflet will give you more information about eprosartan and a full list of possible side-effects from taking it.
  • Take eprosartan exactly as your doctor has told you to. It is usual to take one tablet a day, although there are several strengths of tablet. Each time you collect a prescription, check to make sure it is the strength of tablet that you are expecting.
  • Try to take eprosartan at the same time of day each day. This will help you to remember to take it regularly. You can take eprosartan tablets before or after meals.
  • If you forget to take a dose, take it as soon as you remember. If you do not remember until the following day, skip the missed dose. Do not take two doses together to make up for a forgotten dose.
  • Try to keep your regular appointments with your doctor. This is so your progress can be monitored and your blood pressure measured. Your doctor will want you to have some blood tests from time to time to check on your kidneys, and also how much potassium is in your blood.
  • If you buy any medicines, check with a pharmacist that they are suitable to take with eprosartan. This is because some anti-inflammatory painkillers (such as aspirin and ibuprofen) may interfere with the way it works, and also may increase the risk of side-effects.
  • It is very important that you follow any dietary and lifestyle advice that you may have been given by your doctor, such as eating a healthy diet, not smoking, and taking regular exercise.
  • If you drink alcohol, ask your doctor for advice about drinking while you are on eprosartan. Alcohol will increase the risk of you feeling dizzy or faint and so may not be recommended for you.
  • Do not use salt substitutes which contain potassium while you are taking these tablets. This is because they increase the amount of potassium in your blood and this can cause problems.
  • If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking eprosartan. This is because it may make your blood pressure drop too low when taken with an anaesthetic.
  • Treatment with eprosartan is usually long-term unless you experience an adverse effect. Continue to take the tablets unless you are advised otherwise by your doctor.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. Side-effects from eprosartan are uncommon and usually improve as your body adjusts to the new medicine, but you should speak with your doctor or pharmacist if any of the following side-effects continue or become troublesome.

Eprosartan side-effectsWhat can I do if I experience this?
Feeling faint, tired, or light-headedIf any of these become troublesome, discuss them with your doctor
Headache, stomach upset, muscle aches, runny or stuffy nose, flatulence (wind)Ask your pharmacist to recommend a suitable remedy. If any continues or becomes troublesome, let your doctor know
Changes to some blood testsYour doctor will check for these

Important: if you get any swelling of your mouth or face, speak with your doctor or go to your local accident and emergency department straightaway. These are signs of an allergic reaction.

If you experience any other symptoms which you think may be due to this medicine, speak with your doctor or pharmacist.

  • Keep all medicines out of the reach and sight of children.
  • Store in a cool, dry place, away from direct heat and light.

Never take more than the prescribed dose. If you suspect that you or someone else might have taken an overdose of this medicine, go to the accident and emergency department of your local hospital at once. Take the container with you, even if it is empty.

This medicine is for you. Never give it to other people even if their condition appears to be the same as yours.

Do not keep out-of-date or unwanted medicines. Take them to your local pharmacy which will dispose of them for you.

If you have any questions about this medicine ask your pharmacist.
