Losartan Potassium
Losartan (COZAAR) 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 the blood vessel walls, causing them to narrow. This results in an increase in blood pressure. Losartan prevents angiotensin II from binding to these receptors, causing the blood vessels to widen and thereby lowering the blood pressure. Losartan slows the progression of kidney disease in patients with high blood pressure and type 2 diabetes.
COZAAR is used
Before taking COZAAR, tell your doctor, pharmacist, or nurse.
Inform your doctor if you are planning to become pregnant. Your doctor will normally advise you to stop taking COZAAR before you become pregnant or as soon as you know you are pregnant and will advise you to take another medicine instead of COZAAR. You must not take COZAAR if you are more than 3 months pregnant, as it may seriously harm your baby (see section "Pregnancy").
It is important to tell your doctor before taking COZAAR:
If you take COZAAR and experience stomach pain, nausea, vomiting, or diarrhoea, you should consult your doctor. Your doctor will decide whether you should continue to take COZAAR.
Do not take COZAAR without consulting your doctor.
COZAAR has been studied in children. For more information, please contact your doctor.
COZAAR is not recommended for children with kidney or liver disease, as there is limited experience with COZAAR in these patient groups. COZAAR is not recommended for use in children under 6 years of age, as the efficacy has not been established in this age group.
Tell your doctor or pharmacist about all the medicines you are taking or have recently taken, and those you plan to take.
Tell your doctor about any supplements containing potassium, salt substitutes containing potassium, or potassium-sparing diuretics (such as amiloride, triamterene, spironolactone), or other medicines that may increase potassium levels in your blood (e.g., heparin, trimethoprim-containing medicines), as these should not be taken with COZAAR.
When taking COZAAR, be particularly careful when taking other blood pressure lowering medicines, as they may cause a further decrease in blood pressure.
Your doctor may need to change your dose and take other precautions:
In patients with kidney disease, taking these medicines together may lead to worsening of kidney function.
Do not take medicines containing lithium in combination with losartan without close monitoring by your doctor.
Special precautions (e.g., blood tests) may be necessary.
COZAAR can be taken with or without food.
You should avoid drinking grapefruit juice while taking COZAAR.
Inform your doctor if you are planning to become pregnant. Your doctor will normally advise you to stop taking COZAAR before you become pregnant or as soon as you know you are pregnant and will advise you to take another medicine instead of COZAAR. Do not take COZAAR if you are more than 3 months pregnant, as it may seriously harm your baby.
Inform your doctor if you are breast-feeding or plan to breast-feed. COZAAR is not recommended for use during breast-feeding, especially in newborns or preterm infants. Your doctor may prescribe another medicine for you.
Before taking this medicine, consult your doctor or pharmacist.
No studies on the effects on the ability to drive and use machines have been performed.
It is unlikely that COZAAR will affect your ability to drive or use machines. However, as with many other medicines used to treat high blood pressure, losartan may cause dizziness or tiredness in some people.
If you experience dizziness or tiredness, you should consult your doctor before performing tasks that require alertness.
COZAAR 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.
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 determine the appropriate dose of COZAAR, depending on your condition and any other medicines you are taking. It is important to continue taking COZAAR for as long as your doctor prescribes it to maintain control of your blood pressure.
Adult patients with high blood pressure
Treatment usually starts with 50 mg losartan (one COZAAR 50 mg tablet) once daily. The maximum effect on blood pressure usually occurs within 3-6 weeks of starting treatment. For some patients, a dose of 100 mg losartan (two COZAAR 50 mg tablets or one COZAAR 100 mg tablet) once daily may be required.
Children under 6 years of age
COZAAR is not recommended for children under 6 years of age, as the efficacy has not been established in this age group.
Children from 6 to 18 years of age
The recommended starting dose for patients weighing between 20 kg and 50 kg is 0.7 mg losartan per kg body weight per day (up to 25 mg COZAAR), given once daily. Your doctor may increase the dose if blood pressure is not controlled.
Your doctor may prescribe a lower dose, especially when starting treatment in certain patients, such as those taking high doses of diuretics, patients with liver disease, or patients over 75 years of age. Do not take losartan if you have severe liver disease (see section "Do not take COZAAR").
Swallow the tablets with a glass of water. Try to take your daily dose at the same time each day. It is important to continue taking COZAAR unless your doctor tells you to stop.
If you have taken too many tablets, contact your doctor or pharmacist immediately. Symptoms of overdose include low blood pressure, fast heart rate, and possibly slow heart rate.
If you miss a dose, take the next dose at the usual time. Do not take a double dose to make up for a forgotten tablet. If you have any further questions on the use of this medicine, ask your doctor, pharmacist, or nurse.
