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
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).
It is important to tell your doctor before taking 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.
Tell your doctor if you are taking potassium supplements, potassium-containing salt substitutes, potassium-sparing medicines, or other medicines that may increase serum potassium (e.g., trimethoprim-containing medicines), as the combination with Cozaar Comp is not advisable.
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 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:
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.

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
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.

3. How to take COZAAR COMP
