MicardisPlus 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.
MicardisPlus 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.
Do not take MicardisPlus
- if you are allergic (hypersensitive) to telmisartan or any other ingredients included in MicardisPlus 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 MicardisPlus 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 MicardisPlus.
Take special care with MicardisPlus
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.
- 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. MicardisPlus 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 MicardisPlus.
The use of MicardisPlus 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 MicardisPlus:
- 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.
MicardisPlus 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 MicardisPlus.
As with other blood pressure lowering medicines, the effect of MicardisPlus may be reduced when you take NSAIDs (non steroidal anti-inflammatory medicines, e.g. aspirin or ibuprofen).
Taking MicardisPlus with food and drink
You can take MicardisPlus 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 MicardisPlus before you become pregnant or as soon as you know you are pregnant and will advise you to take another medicine instead of MicardisPlus. MicardisPlus 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. MicardisPlus 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 MicardisPlus 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.

MicardisPlus is a medicine that contains two active substances, telmisartan and hydrochlorothiazide. It is available as oval tablets (red and white: 40 mg or 80 mg telmisartan and 12.5 mg hydrochlorothiazide; yellow and white: 80 mg telmisartan and 25 mg hydrochlorothiazide).
MicardisPlus is used in patients who have essential hypertension (high blood pressure) that is not adequately controlled by telmisartan alone. ‘Essential’ means that the hypertension has no obvious cause. MicardisPlus is not recommended for use in patients below 18 years of age, because of a lack of information on safety and effectiveness in this age group.
The medicine can only be obtained with a prescription.
MicardisPlus is taken by mouth once a day with liquid, with or without food. The dose of MicardisPlus to be used depends on the dose of telmisartan that the patient was taking before: patients who were receiving 40 mg telmisartan should take the 40/12.5 mg tablets, and patients who were receiving 80 mg telmisartan should take the 80/12.5 mg tablets. The 80/25 mg tablets are used in patients whose blood pressure is not controlled using the 80/12.5 mg tablets or who have been stabilised using the two active substances taken separately before switching to MicardisPlus.
MicardisPlus contains two active substances, telmisartan and hydrochlorothiazide. Telmisartan is an ‘angiotensin II receptor antagonist’, which means that it blocks the action of a hormone in the body called angiotensin II. Angiotensin II is a powerful vasoconstrictor (a substance that narrows blood vessels). By blocking the receptors to which angiotensin II normally attaches, telmisartan stops the hormone having an effect, allowing the blood vessels to widen. Hydrochlorothiazide is a diuretic, which is another type of treatment for hypertension. It works by increasing urine output, reducing the amount of fluid in the blood and reducing the blood pressure. The combination of the two active substances has an additive effect, reducing the blood pressure more than either medicine alone. By lowering the blood pressure, the risks associated with high blood pressure, such as having a stroke, are reduced.
MicardisPlus has been studied in five main studies involving a total of 2,985 patients with mild to moderate hypertension. In four of these studies, MicardisPlus was compared with placebo (a dummy treatment) and with telmisartan taken alone in a total of 2,272 patients. The fifth study compared the effects of remaining on the 80/12.5 mg tablet with switching to the 80/25 mg tablet in 713 patients who had not responded to the 80/12.5 mg tablet. In all studies, the main measure of effectiveness was the reduction in diastolic blood pressure (the blood pressure measured between two heartbeats).
MicardisPlus was more effective at reducing diastolic blood pressure than telmisartan taken alone and than placebo. In patients who were not controlled on the 80/12.5 mg tablet, switching to the 80/25 mg tablet was more effective in reducing diastolic blood pressure than remaining on the lower dose.
The most common side effect with MicardisPlus (seen in between 1 and 10 patients in 100) is dizziness. For the full list of all side effects reported with MicardisPlus, see the Package Leaflet. MicardisPlus should not be used in people who may be hypersensitive (allergic) to telmisartan, hydrochlorothiazide, sulfonamides or any of the other ingredients (including sorbitol). It must not be used in women who are more than three months pregnant. Its use during the first three months of pregnancy is not recommended. MicardisPlus must also not be used in people who have severe liver, kidney or bile problems, blood potassium levels that are too low, or blood calcium levels that are too high.
Care must be taken when using MicardisPlus with other medicines that have an effect on blood potassium levels. The full list of these medicines is given in the Package Leaflet.
The Committee for Medicinal Products for Human Use (CHMP) decided that MicardisPlus’s benefits are greater than its risks for the treatment of essential hypertension in patients whose blood pressure is not adequately controlled on telmisartan alone. The Committee recommended that MicardisPlus be given marketing authorisation.
The European Commission granted a marketing authorisation valid throughout the European Union for MicardisPlus to Boehringer Ingelheim International GmbH on 19 April 2002. The marketing authorisation was renewed on 19 April 2007.
