CoAprovel is a combination of two active substances, irbesartan and hydrochlorothiazide.

Irbesartan belongs to a group of medicines known as angiotensin- II receptor antagonists. Angiotensin-II is a substance produced in the body that binds to receptors in blood vessels causing them to tighten. This results in an increase in blood pressure. Irbesartan prevents the binding of angiotensin-II to these receptors, causing the blood vessels to relax and the blood pressure to lower.

Hydrochlorothiazide is one of a group of medicines (called thiazide diuretics) that causes increased urine output and so causes a lowering of blood pressure.

The two active ingredients in CoAprovel work together to lower blood pressure further than if either was given alone.

CoAprovel is used to treat high blood pressure, when treatment with irbesartan or hydrochlorothiazide alone did not provide adequate control of your blood pressure.

Do not take CoAprovel
  • if you are allergic to irbesartan or any of the other ingredients of this medicine (listed in section 6)
  • if you are allergic to hydrochlorothiazide or any other sulfonamide-derived medicines
  • if you are more than 3 months pregnant. (It is also better to avoid CoAprovel in early pregnancy - see pregnancy section)
  • if you have severe liver or kidney problems
  • if you have difficulty in producing urine
  • if your doctor determines that you have persistently high calcium or low potassium levels in your blood
  • if you have diabetes or impaired kidney function and you are treated with a blood pressure lowering medicine containing aliskiren.

Warnings and precautions

Talk to your doctor before taking CoAprovel and if any of the following apply to you:

  • if you get excessive vomiting or diarrhoea
  • if you suffer from kidney problems or have a kidney transplant
  • if you suffer from heart problems
  • if you suffer from liver problems
  • if you suffer from diabetes
  • if you develop low blood sugar levels (symptoms may include sweating, weakness, hunger, dizziness, trembling, headache, flushing or paleness, numbness, having a fast, pounding heart beat), particularly if you are being treated for diabetes.
  • if you suffer from lupus erythematosus (also known as lupus or SLE)
  • if you suffer from primary aldosteronism (a condition related to high production of the hormone aldosterone, which causes sodium retention and, in turn, an increase in blood pressure).
  • if you are taking any of the following medicines used to treat high blood pressure:
    • an ACE-inhibitor (for example enalapril, lisinopril, ramipril) in particular if you have diabetes-related kidney problems.
    • aliskiren.
  • if you have had skin cancer or if you develop an unexpected skin lesion during the treatment. Treatment with hydrochlorothiazide, particularly long term use with high doses, may increase the risk of some types of skin and lip cancer (non-melanoma skin cancer). Protect your skin from sun exposure and UV rays while taking CoAprovel.
  • if you experienced breathing or lung problems (including inflammation or fluid in the lungs) following hydrochlorothiazide intake in the past. If you develop any severe shortness of breath or difficulty breathing after taking CoAprovel, seek medical attention immediately.

Your doctor may check your kidney function, blood pressure, and the amount of electrolytes (e.g. potassium) in your blood at regular intervals.

See also information under the heading “Do not take CoAprovel”.

You must tell your doctor if you think you are (or might become) pregnant. CoAprovel 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).

You should also tell your doctor:
  • if you are on a low-salt diet
  • if you have signs such as abnormal thirst, dry mouth, general weakness, drowsiness, muscle pain or cramps, nausea, vomiting, or an abnormally fast heart beat which may indicate an excessive effect of hydrochlorothiazide (contained in CoAprovel)
  • if you experience an increased sensitivity of the skin to the sun with symptoms of sunburn (such as redness, itching, swelling, blistering) occurring more quickly than normal
  • if you are going to have an operation (surgery) or be given anaesthetics
  • if you have decrease in your vision or pain in one or both of your eyes while taking CoAprovel. These could be symptoms of fluid accumulation in the vascular layer of the eye (choroidal effusion) or an increase of pressure in your eye (glaucoma) and can happen within hours to a week of taking CoAprovel. This can lead to permanent vision loss, if not treated. If you earlier have had a penicillin or sulfonamide allergy, you can be at higher risk of developing this. You should discontinue CoAprovel treatment and seek prompt medical attention.

The hydrochlorothiazide contained in this medicine could produce a positive result in an anti-doping test.

Children and adolescents

CoAprovel should not be given to children and adolescents (under 18 years).

Other medicines and CoAprovel

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Diuretic agents such as the hydrochlorothiazide contained in CoAprovel may have an effect on other medicines. Preparations containing lithium should not be taken with CoAprovel without close supervision by your doctor.

Your doctor may need to change your dose and/or to take other precautions:

If you are taking an ACE-inhibitor or aliskiren (see also information under the headings “Do not take CoAprovel” and “Warnings and precautions”).

You may need to have blood checks if you take:

  • potassium supplements
  • salt substitutes containing potassium
  • potassium sparing medicines or other diuretics (water tablets)
  • some laxatives
  • medicines for the treatment of gout
  • therapeutic vitamin D supplements
  • medicines to control heart rhythm
  • medicines for diabetes (oral agents as repaglinide or insulins)
  • carbamazepine (a medicine for the treatment of epilepsy).

It is also important to tell your doctor if you are taking other medicines to reduce your blood pressure, steroids, medicines to treat cancer, pain killers, arthritis medicines, or colestyramine and colestipol resins for lowering blood cholesterol.

CoAprovel with food and drink

CoAprovel can be taken with or without food.

Due to the hydrochlorothiazide contained in CoAprovel, if you drink alcohol while on treatment with this medicine, you may have an increased feeling of dizziness on standing up, specially when getting up from a sitting position.

Pregnancy, breast-feeding and fertility


You must tell your doctor if you think you are (or might become) pregnant. Your doctor will normally advise you to stop taking CoAprovel before you become pregnant or as soon as you know you are pregnant and will advise you to take another medicine instead of CoAprovel. CoAprovel 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. CoAprovel 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

CoAprovel is unlikely to affect your ability to drive or use machines. However, occasionally dizziness or weariness may occur during treatment of high blood pressure. If you experience these, talk to your doctor before attempting to drive or use machines.

CoAprovel contains lactose. If you have been told by your doctor that you have an intolerance to some sugars (e.g. lactose), contact your doctor before taking this medicinal product.

CoAprovel contains sodium. This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially ‘sodium-free’.


Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.


The recommended dose of CoAprovel is one tablet a day. CoAprovel will usually be prescribed by your doctor when your previous treatment did not reduce your blood pressure enough. Your doctor will instruct you how to switch from the previous treatment to CoAprovel.

Method of administration

CoAprovel is for oral use. Swallow the tablets with a sufficient amount of fluid (e.g. one glass of water). You can take CoAprovel with or without food. Try to take your daily dose at about the same time each day. It is important that you continue to take CoAprovel until your doctor tells you otherwise.

The maximal blood pressure lowering effect should be reached 6-8 weeks after beginning treatment.

If you take more CoAprovel than you should

If you accidentally take too many tablets, contact your doctor immediately.

Children should not take CoAprovel

CoAprovel should not be given to children under 18 years of age. If a child swallows some tablets, contact your doctor immediately.

If you forget to take CoAprovel

If you accidentally miss a daily dose, just take the next dose as normal. Do not take a double dose to make up for a forgotten dose.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
