Pack contents and additional information

1. What Telmisartán/Hidroclorotiazida Alter is and what it is used for

Telmisartán/Hidroclorotiazida Alter is a combination of two active substances, telmisartan and hydrochlorothiazide, in one tablet. Both active substances help control high blood pressure.

• Telmisartan belongs to a group of medicines known as angiotensin II receptor antagonists. Angiotensin II is a substance produced in your body that causes your blood vessels to narrow, thereby increasing your blood pressure. Telmisartan blocks the effect of angiotensin II, allowing blood vessels to relax and thus lowering your blood pressure.
• Hydrochlorothiazide belongs to a group of medicines known as thiazide diuretics, which increase your urine output, resulting in a reduction of your blood pressure.

If left untreated, high blood pressure can damage blood vessels in various organs, sometimes leading to heart attack, heart or kidney failure, stroke, or blindness. High blood pressure usually causes no symptoms before such damage occurs. Therefore, it is important to have your blood pressure checked regularly to ensure it remains within the normal range.

Telmisartán/Hidroclorotiazida Alter is used for the treatment of high blood pressure (essential hypertension) in adults whose blood pressure is not adequately controlled with telmisartan/hydrochlorothiazide 80 mg/12.5 mg, or in patients who have previously been stabilized on telmisartan and hydrochlorothiazide given separately.

2. What you need to know before taking Telmisartan/Hydrochlorothiazide Alter

Do not take Telmisartan/Hydrochlorothiazide Alter

• if you are allergic to telmisartan, hydrochlorothiazide, or to other sulfonamide-derived medicines, or to any of the other ingredients of this medicine (listed in section 6)
• if you are more than 3 months pregnant. (In any case, it is better to avoid taking this medicine also during early pregnancy – see section Pregnancy)
• if you have severe liver problems such as cholestasis or biliary obstruction (problems with bile drainage from the liver and gallbladder), or any other serious liver disease
• if you have severe kidney disease
• if your doctor has determined that you have low potassium levels or high calcium levels in blood that do not improve with treatment
• if you have diabetes or kidney failure and are being treated with a blood pressure-lowering medicine containing aliskiren.

If any of the above apply to you, inform your doctor or pharmacist before using Telmisartan/Hydrochlorothiazide Alter.

Warnings and precautions

Talk to your doctor before taking this medicine if you have or have had any of the following conditions or diseases:

• If you have had skin cancer or if you develop an unexpected skin lesion during treatment. Treatment with hydrochlorothiazide, particularly long-term use at high doses, may increase the risk of certain types of non-melanoma skin cancer and lip cancer. Protect your skin from exposure to sunlight and UV rays while taking Telmisartan/Hydrochlorothiazide Alter.
• Low blood pressure (hypotension), which may occur if you are dehydrated (excessive loss of body water) or have salt deficiency due to treatment with diuretics, a low-sodium 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 problems.
• Diabetes.
• Gout.
• Elevated levels of aldosterone (water and salt retention in the body along with imbalance of several blood minerals).
• Systemic lupus erythematosus (also called “lupus” or “SLE”), a disease in which the body’s immune system attacks the body itself.
• The active ingredient hydrochlorothiazide may cause a rare reaction leading to vision loss and eye pain. These symptoms may indicate fluid accumulation in the vascular layer of the eye (choroidal effusion) or increased eye pressure and may appear from hours to weeks after taking telmisartan/hydrochlorothiazide. If untreated, this may lead to permanent vision impairment.

Consult your doctor before taking this medicine:

• if you are taking any of the following medicines used to treat high blood pressure (hypertension):
  • an angiotensin-converting enzyme inhibitor (ACE inhibitor) (e.g. enalapril, lisinopril, ramipril), particularly if you have kidney problems related to diabetes
  • aliskiren

Your doctor may monitor your kidney function, blood pressure, and blood electrolyte levels (e.g. potassium) at regular intervals. See also information under the heading “Do not take Telmisartan/Hydrochlorothiazide Alter”.

• if you are taking digoxin.
• if you have previously experienced breathing or lung problems (such as inflammation or fluid in the lungs) after taking hydrochlorothiazide. If you develop shortness of breath or severe difficulty breathing after taking Telmisartan/Hydrochlorothiazide Alter, seek medical attention immediately.

Talk to your doctor if you experience abdominal pain, nausea, vomiting, or diarrhoea after taking Telmisartan/Hydrochlorothiazide Alter. Your doctor will decide whether to continue treatment. Do not stop taking Telmisartan/Hydrochlorothiazide Alter as monotherapy.

If you are pregnant, suspect you may be pregnant, or plan to become pregnant, inform your doctor. Use of telmisartan/hydrochlorothiazide is not recommended during early pregnancy (first 3 months) and must not be used from the third month of pregnancy onwards, as it may cause serious harm to your baby – see section Pregnancy.

Treatment with hydrochlorothiazide may cause an electrolyte imbalance in your body. Typical symptoms of fluid or electrolyte imbalance include dry mouth, weakness, lethargy, drowsiness, restlessness, muscle pain or cramps, nausea, vomiting, muscle fatigue, and abnormally rapid heartbeat (more than 100 beats per minute). If you experience any of these symptoms, inform your doctor.

You should also inform your doctor if you develop increased skin sensitivity to sunlight with symptoms of sunburn (such as redness, itching, swelling, or blistering) appearing more quickly than usual.

If you are scheduled for surgery or anaesthesia, inform your doctor that you are taking telmisartan/hydrochlorothiazide.

Telmisartan/hydrochlorothiazide may be less effective in lowering blood pressure in black patients.

Children and adolescents

Use of telmisartan/hydrochlorothiazide is not recommended in children and adolescents under 18 years of age.

Taking Telmisartan/Hydrochlorothiazide Alter with other medicines

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines. Your doctor may need to adjust the dose of these other medicines or take other precautions. In some cases, you may need to stop taking one of these medicines, especially if you are using any of the following together with telmisartan/hydrochlorothiazide:

• Medicines containing lithium used to treat certain types of depression.
• Medicines associated with low potassium levels in blood (hypokalaemia), such as other diuretics, laxatives (e.g. castor oil), corticosteroids (e.g. prednisone), ACTH (adrenocorticotropic hormone), amphotericin (an antifungal medicine), carbenoxolone (used to treat mouth ulcers), sodium penicillin G (an antibiotic), and acetylsalicylic acid and its derivatives.
• Medicines that may increase potassium levels in blood, such as potassium-sparing diuretics, potassium supplements, potassium-containing salt substitutes, ACE inhibitors that may raise potassium levels, cyclosporine (an immunosuppressant), and other medicines such as sodium heparin (an anticoagulant).
• Medicines affected by changes in blood potassium levels, such as heart medicines (e.g. digoxin) or medicines to control your heart rhythm (e.g. quinidine, disopyramide, amiodarone, sotalol), medicines used for mental disorders (e.g. thioridazine, chlorpromazine, levomepromazine), and other medicines such as certain antibiotics (e.g. sparfloxacin, pentamidine) or certain medicines to treat allergic reactions (e.g. terfenadine).
• Medicines for the treatment of diabetes (insulins or oral agents such as metformin).
• Cholestyramine and colestipol, medicines used to reduce blood fat levels.
• Medicines to increase blood pressure, such as noradrenaline.
• Muscle relaxants, such as tubocurarine.
• Calcium and/or vitamin D supplements.
• Other medicines used to treat high blood pressure, corticosteroids, painkillers (such as non-steroidal anti-inflammatory drugs [NSAIDs]), medicines for cancer, gout, or arthritis.
• If you are taking an angiotensin-converting enzyme inhibitor (ACE inhibitor) or aliskiren (see also information under the headings “Do not take Telmisartan/Hydrochlorothiazide Alter” and “Warnings and precautions”).
• Digoxin.

Telmisartan/hydrochlorothiazide may enhance the blood pressure-lowering effect of other medicines or of medicines that may potentially lower blood pressure (e.g. baclofen, amifostine).

Additionally, the reduction in blood pressure may be worsened by alcohol, barbiturates, narcotics, or antidepressants. You may notice this effect as dizziness upon standing. Inform your doctor, as dose adjustments of your other medicines may be needed while taking telmisartan/hydrochlorothiazide.

The effect of telmisartan/hydrochlorothiazide may be reduced when used with NSAIDs (non-steroidal anti-inflammatory drugs, e.g. aspirin or ibuprofen).

Taking Telmisartan/Hydrochlorothiazide Alter with food and alcohol

You may take this medicine with or without food.

Avoid alcohol until you have spoken with your doctor. Alcohol may further lower your blood pressure and/or increase the risk of dizziness or weakness.

Pregnancy and breast-feeding

If you are pregnant, breast-feeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.

Pregnancy

Inform your doctor if you are pregnant, suspect you may be pregnant, or plan to become pregnant. Your doctor will usually advise you to stop taking telmisartan/hydrochlorothiazide before becoming pregnant or as soon as pregnancy is confirmed, and will recommend an alternative antihypertensive medicine. Telmisartan/hydrochlorothiazide is not recommended during pregnancy and must not be used from the third month of pregnancy onwards, as it may cause serious harm to your baby when used from that time.

Breast-feeding

Inform your doctor if you are planning to start or are currently breast-feeding, as telmisartan/hydrochlorothiazide is not recommended for women during this period. Your doctor may decide to prescribe a more suitable treatment if you wish to breast-feed.

Driving and using machines

Some patients feel dizzy or tired when taking telmisartan/hydrochlorothiazide. If you feel dizzy or tired, do not drive or operate machinery.

Telmisartan/Hydrochlorothiazide Alter contains sorbitol

This medicine contains 42.948 mg of sorbitol per tablet, equivalent to 56.51 mg/g.

3. How to take Telmisartan/Hydrochlorothiazide Alter

Follow exactly the instructions for use of this medicine given by your doctor. If in doubt, consult your doctor or pharmacist again.

The recommended dose is one tablet daily. Try to take the tablet at the same time each day. You may take telmisartan/hydrochlorothiazide with or without food. Tablets should be swallowed with a little water or other non-alcoholic drink. It is important that you take telmisartan/hydrochlorothiazide every day until your doctor tells you otherwise.
