Although ‘Cozaar’-Comp contains a very small amount of potassium, it cannot replace potassium supplements. If your doctor has prescribed potassium supplements, continue to follow the advice given.
‘Cozaar’-Comp contains two active ingredients. These are losartan potassium and hydrochlorothiazide. Losartan belongs to a group of medicines known as angiotensin-II receptor antagonists. Angiotensin II is a chemical occurring in the body, which tightens your blood vessels making it harder for the blood to pass through them and causing your blood pressure to increase. ‘Cozaar’-Comp blocks this effect of angiotensin II, causing the blood vessels to relax. Hydrochlorothiazide works by making your kidneys pass more water and salt. Together, losartan and hydrochlorothiazide lower high blood pressure. Although your doctor will be able to tell you that the medicine is working by measuring your blood pressure, you probably will feel no different while you are taking ‘Cozaar’-Comp.
Your doctor has prescribed ‘Cozaar’-Comp because you have a condition known as hypertension, or high blood pressure.
Blood pressure is the term given to the pressure produced by your heart pumping blood to all parts of your body. Your blood pressure is measured by two numbers, e.g. 120/80 mm Hg. The top number measures the pressure while your heart beats and the bottom number measures the pressure in between heartbeats.
Normal blood pressure is part of good health. High blood pressure is caused when the blood vessels tighten and the measurement goes above the normal range for your age. There are usually no symptoms of high blood pressure and you will only know you have it if you have had your blood pressure measured.
Although you might feel quite well, if your high blood pressure is not treated, it can damage your heart and kidneys, and in some cases lead to stroke, heart attack, heart and/or kidney failure, or blindness.
High blood pressure can be treated and controlled with medicines such as ‘Cozaar’-Comp. Your doctor may also recommend that you make some changes to your lifestyle to help your high blood pressure, such as losing weight, keeping alcohol intake moderate or avoiding it altogether, stopping smoking, and reducing the amount of salt in your diet. Your doctor may also encourage you to take more mild exercise.
‘Cozaar’-Comp should not be given to children.
It is important to tell your doctor before taking ‘Cozaar’-Comp if you suffer from gout, diabetes, lupus erythematosus, or if you are being treated with other diuretics (water tablets). In these cases, your doctor may need to adjust the dose of your medications.
Tell your doctor if you have recently suffered from excessive vomiting and/or diarrhoea or if you have parathyroid problems.
Tell your doctor if you have a condition called ‘aortic stenosis’ or ‘outflow obstruction’.
If you have received a kidney transplant you should inform your doctor.
You should also tell your doctor if you have high levels of potassium in your blood (hyperkalaemia) or you are on a low potassium diet.
Before surgery and anaesthesia (even at the dentist), tell the doctor or dentist that you are taking ‘Cozaar’-Comp, as there may be a sudden fall in blood pressure associated with the anaesthesia. In addition, if you are going to have a blood test, you should let your doctor know that you are taking ‘Cozaar’-Comp. ‘Cozaar’-Comp can affect the results of some diagnostic tests.
In general, ‘Cozaar’-Comp can be taken with other drugs. You should tell your doctor about all drugs that you are taking or plan to take, including those obtained without a prescription. You should also tell your doctor if you are taking any of the following:
‘Cozaar’-Comp should be taken by mouth.
You must keep taking ‘Cozaar’-Comp every day and exactly as your doctor has told you. It is important that you take ‘Cozaar’-Comp for as long as your doctor prescribes, in order to keep your blood pressure controlled.
Usually patients will start combination therapy with losartan and hydrochlorothiazide with a dose of 50 mg losartan potassium and 12.5 mg hydrochlorothiazide daily. If your blood pressure is not controlled with this, your doctor will normally prescribe one tablet of ‘Cozaar’-Comp daily (100 mg losartan potassium and 25 mg hydrochlorothiazide).
If you are aged over 75 years you should check with your doctor before taking your tablets.
Try to take ‘Cozaar’-Comp daily as prescribed. However, if you miss a dose, just carry on with the next dose as normal. Do not take an extra tablet to make up.
