1. What COZAAR COMP is and what it is used for

Cozaar Comp is a combination of an angiotensin II receptor antagonist (losartan) and a diuretic (hydrochlorothiazide). 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. Losartan prevents the binding of angiotensin II to these receptors, causing the blood vessels to relax which in turn lowers the blood pressure. Hydrochlorothiazide works by making the kidneys pass more water and salt. This also helps to reduce blood pressure.

Cozaar Comp is indicated for the treatment of essential hypertension (high blood pressure).

2. What you need to know before you take COZAAR COMP

Do not take Cozaar Comp

  • if you are allergic to losartan, hydrochlorothiazide or to any of the other ingredients of this medicine (listed in section 6),
  • if you are allergic to other sulfonamide-derived substances (e.g. other thiazides, some antibacterial drugs such as co-trimoxazole, ask your doctor if you are not sure),
  • if you have severely impaired liver function,
  • if you have low potassium, low sodium or high calcium levels which cannot be corrected by treatment,
  • if you are suffering from gout,
  • if you are more than 3 months pregnant (It is also better to avoid Cozaar Comp in early pregnancy - see Pregnancy section),
  • if you have severely impaired kidney function or your kidneys are not producing any urine,
  • 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, pharmacist, or nurse before taking Cozaar Comp.

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

  • if you have high calcium or low potassium levels or you are on a low potassium diet;
  • if you need to have an anaesthetic (even at the dentist) or before surgery, or if you are going to have tests to check your parathyroid function, you must tell the doctor or medical staff that you are taking losartan potassium and hydrochlorothiazide tablets;
  • if you suffer from primary hyperaldosteronism (a syndrome associated with increased secretion of the hormone aldosterone by the adrenal gland, caused by an abnormality within the gland);
  • 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.

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

Children and adolescents

There is no experience with the use of Cozaar Comp in children. Therefore, Cozaar Comp should not be given to children.

Other medicines and Cozaar Comp

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 Cozaar Comp may interact with other medicines.

Preparations containing lithium should not be taken with Cozaar Comp without close supervision by your doctor.

Special precautionary measures (e.g. blood tests) may be appropriate if you take potassium supplements, potassium-containing salt substitutes or potassium-sparing medicines, other diuretics (“water tablets”), some laxatives, medicines for the treatment of gout, medicines to control heart rhythm or for diabetes (oral agents or insulins).

It is also important for your doctor to know if you are taking:

  • other medicines to reduce your blood pressure;
  • steroids;
  • medicines to treat cancer;
  • pain killers;
  • drugs for treatment of fungal infections;
  • arthritis medicines;
  • resins used for high cholesterol, such as colestyramine;
  • medicines which relax your muscles;
  • sleeping tablets;
  • opioid medicines such as morphine;
  • ‘pressor amines’ such as adrenaline or other drugs from the same group;
  • oral agents for diabetes or insulins;

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 Cozaar Comp” and “Warnings and precautions”).

Please also inform your doctor you are taking Cozaar Comp if you will be undergoing a radiographic procedure and will be given iodine contrast media.

Cozaar Comp with food and drink

You are advised not to drink alcohol whilst taking these tablets: alcohol and Cozaar Comp tablets may increase each other’s effects.

Dietary salt in excessive quantities may counteract the effect of Cozaar Comp tablets.

Cozaar Comp tablets may be taken with or without food.

Pregnancy and breast-feeding

Pregnancy

You must tell your doctor if you think you are (or might become) pregnant. Your doctor will normally advise you to stop taking Cozaar Comp before you become pregnant or as soon as you know you are pregnant and will advise you to take another medicine instead of Cozaar Comp. Cozaar Comp is not recommended during 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.

Breast-feeding

Tell your doctor if you are breast-feeding or about to start breast-feeding. Cozaar Comp is not recommended for mothers who are breast-feeding, and your doctor may choose another treatment for you if you wish to breast-feed.

Use in elderly patients

Cozaar Comp works equally well in and is equally well tolerated by most older and younger adult patients. Most older patients require the same dose as younger patients.

Driving and using machines

When you begin treatment with this medication, you should not perform tasks which may require special attention (for example, driving an automobile or operating dangerous machinery) until you know how you tolerate your medicine.

Cozaar Comp contains lactose

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.

3. How to take COZAAR COMP

Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure. Your doctor will decide on the appropriate dose of Cozaar Comp depending on your condition and whether you are taking other medicines. It is important to continue taking Cozaar Comp for as long as your doctor prescribes it in order to maintain smooth control of your blood pressure.

High Blood Pressure

The usual dose of Cozaar Comp for most patients with high blood pressure is 1 tablet of Cozaar Comp 50 mg/12.5 mg per day to control blood pressure over the 24-hour period. This can be increased to 2 tablets once daily of Losartan / Hydrochlorothiazide 50 mg/12.5 mg Film-Coated Tablets or changed to 1 tablet daily of Losartan / Hydrochlorothiazide 100 mg/25 mg Film-Coated Tablets (a stronger strength) per day. The maximum daily dose is 2 tablets per day of Losartan / Hydrochlorothiazide 50 mg/12.5 mg Film-Coated Tablets or 1 tablet daily of Losartan / Hydrochlorothiazide 100 mg/25 mg Film-Coated Tablets.

Administration

The tablets should be swallowed whole with a glass of water.

If you take more Cozaar Comp than you should

In case of an overdose, contact your doctor immediately so that medical attention may be given promptly. Overdose can cause a drop in blood pressure, palpitations, slow pulse, changes in blood composition, and dehydration.

If you forget to take Cozaar Comp
