What is it and how is it used?

Kinzalkomb is a combination of two active substances, telmisartan and hydrochlorothiazide in one tablet. Both of these substances help to control high blood pressure.

  • Telmisartan belongs to a group of medicines called angiotensin II receptor antagonists. Angiotensin-II is a substance produced in your body which causes your blood vessels to narrow thus increasing your blood pressure. Telmisartan blocks the effect of angiotensin II so that the blood vessels relax, and your blood pressure is lowered.
  • Hydrochlorothiazide belongs to a group of medicines called thiazide diuretics, which cause your urine output to increase, leading to a lowering of your blood pressure.

High blood pressure, if not treated, can damage blood vessels in several organs, which could lead sometimes to heart attack, heart or kidney failure, stroke, or blindness. There are usually no symptoms of high blood pressure before damage occurs. Thus it is important to regularly measure blood pressure to verify if it is within the normal range.

Kinzalkomb is used to treat high blood pressure (essential hypertension) in patients whose blood pressure is not controlled enough when either telmisartan or hydrochlorothiazide is used alone.

What do you have to consider before using it?

Do not take Kinzalkomb

  • if you are allergic (hypersensitive) to telmisartan or any other ingredients included in Kinzalkomb tablets (see "Further information" for a list of other ingredients).
  • if you are allergic (hypersensitive) to hydrochlorothiazide or to any other sulfonamide-derived medicines.
  • if you are more than 3 months pregnant. (It is also better to avoid Kinzalkomb in early pregnancy ? see pregnancy section.)
  • if you have severe liver problems such as cholestasis or biliary obstruction (problems with drainage of the bile from the gall bladder) or any other severe liver disease.
  • if you have severe kidney disease.
  • if your doctor determines that you have low potassium levels or high calcium levels in your blood that do not get better with treatment.

If any of the above applies to you, tell your doctor or pharmacist before taking Kinzalkomb.

Take special care with Kinzalkomb

Please tell your doctor if you are suffering or have ever suffered from any of the following conditions or illnesses:

  • Low blood pressure (hypotension), likely to occur if you are dehydrated (excessive loss of body water) or have salt deficiency due to diuretic therapy (water tablets), low-salt diet, diarrhoea, vomiting, or haemodialysis.
  • Kidney disease or kidney transplant.
  • Renal artery stenosis (narrowing of the blood vessels to one or both kidneys).
  • Liver disease.
  • Heart trouble.
  • Diabetes.
  • Gout.
  • Raised aldosterone levels (water and salt retention in the body along with imbalance of various blood minerals).
  • Lupus erythematosus (also called ?lupus? or ?SLE?) a disease where the body?s immune system attacks the body.

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

Treatment with hydrochlorothiazide may cause electrolyte imbalance in your body. Typical symptoms of fluid or electrolyte imbalance include dry mouth, weakness, lethargy, drowsiness, restlessness, muscle pain or cramps, nausea (feeling sick), vomiting, tired muscles, and an abnormally fast heart rate (faster than 100 beats per minute). If you experience any of these you should tell your doctor.

You should also tell your doctor, 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.

In case of surgery or anaesthetics, you should tell your doctor that you are taking Kinzalkomb.

The use of Kinzalkomb in children and adolescents up to the age of 18 years is not recommended.

As with all other angiotensin II receptor antagonists, telmisartan may be less effective in lowering the blood pressure in black patients.

Taking other medicines:

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription. Your doctor may need to change the dose of these other medications or take other precautions. In some cases you may have to stop taking one of the medicines. This applies especially to the medicines listed below taken at the same time with Kinzalkomb:

  • Lithium containing medicines to treat some types of depression.
  • Medicines associated with low blood potassium (hypokalaemia) such as other diuretics, ('water tablets'), laxatives (e.g. castor oil), corticosteroids (e.g. prednisone), ACTH (a hormone),

amphotericin (an antifungal medicine), carbenoxolone (used to treat mouth ulcers), penicillin G sodium (an antibiotic), and salicylic acid and derivatives.

  • Potassium-sparing diuretics, potassium supplements, salt substitutes containing potassium, ACE inhibitors that may increase blood potassium levels.
  • Heart medicines (e.g. digoxin) or medicines to control the rhythm of your heart (e.g. quinidine, disopyramide).
  • Medicines used for mental disorders (e.g. thioridazine, chlorpromazine, levomepromazine).
  • Other medicines used to treat high blood pressure, steroids, painkillers, medicines to treat cancer, gout, or arthritis, and vitamin D supplements.

Kinzalkomb may increase the blood pressure lowering effect of other medicines and you should consult with your doctor if you need to adjust the dose of your other medicine while taking Kinzalkomb.

As with other blood pressure lowering medicines, the effect of Kinzalkomb may be reduced when you take NSAIDs (non steroidal anti-inflammatory medicines, e.g. aspirin or ibuprofen).

Taking Kinzalkomb with food and drink

You can take Kinzalkomb 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 Kinzalkomb before you become pregnant or as soon as you know you are pregnant and will advise you to take another medicine instead of Kinzalkomb. Kinzalkomb 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. Kinzalkomb 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

No information is available on the effect of Kinzalkomb on the ability to drive or operate machinery. Some people feel dizzy or tired when they are treated for high blood pressure. If you feel dizzy or tired, do not drive or operate machinery.

Important information about some of the ingredients of Kinzalkomb

Kinzalkomb contains milk sugar (lactose) and sorbitol.
If you are intolerant to some sugars, consult your doctor before taking Kinzalkomb.
