1. What is Telmabax and what is it used for
Telmabax belongs to a group of medicines called angiotensin II receptor antagonists.
Angiotensin II is a substance produced by the body that causes blood vessels to constrict, leading to an increase in blood pressure. Telmabax blocks the action of angiotensin II, causing blood vessels to relax and blood pressure to decrease.
Telmabax is usedto treat essential hypertension (high blood pressure) in adults. The term "essential" means that high blood pressure is not caused by another disease.
Untreated high blood pressure can cause damage to blood vessels in various organs, which can lead to heart attack, heart failure, or kidney disease, stroke, or vision loss. Most often, before the above complications occur, no symptoms of high blood pressure are observed. Therefore, blood pressure should be regularly monitored.
Telmabax is also usedto reduce the frequency of cardiovascular events (such as heart attack or stroke) in patients at risk, i.e., those with reduced blood flow to the heart or legs, those who have had a stroke, or those with diabetes.
Your doctor will inform you if you are at risk of these events.
2. Important information before taking Telmabax
When not to take Telmabax
PL/H/0698/002-003/IA/020
- after the third month of pregnancy (you should also avoid taking Telmabax in early pregnancy - see section "Pregnancy");
If any of the above situations apply to you, you should inform your doctor or pharmacist before starting to take Telmabax.
Warnings and precautions
You should inform your doctor if you have or have had any of the following conditions or diseases:
- kidney disease or kidney transplant;
- renal artery stenosis (narrowing of the blood vessels supplying one or both kidneys);
- liver disease;
- heart problems;
- increased aldosterone levels (water and salt retention in the body, accompanied by disturbances in the balance of various minerals);
- low blood pressure (hypotension), which is more likely if you are dehydrated (excessive water loss from the body) or have a low salt level due to the use of diuretics, a low-salt diet, diarrhea, or vomiting;
- high potassium levels in the blood;
- diabetes.
Before starting to take Telmabax, you should discuss this with your doctor or pharmacist:
- angiotensin-converting enzyme (ACE) inhibitor (e.g., enalapril, lisinopril, ramipril), especially if you have kidney problems related to diabetes.
- aliskiren. Your doctor may monitor your kidney function, blood pressure, and electrolyte levels (e.g., potassium) in your blood at regular intervals. See also the information under the heading "When not to take Telmabax" and "Warnings and precautions".
You should inform your doctor if you suspect or plan to become pregnant. It is not recommended to take Telmabax in early pregnancy, and you must not take it after the third month of pregnancy, as it may seriously harm your baby (see section "Pregnancy").
In the event of planned surgery or anesthesia, you should inform your doctor that you are taking Telmabax.
Telmabax may be less effective in lowering blood pressure in black patients.
If you experience stomach pain, nausea, vomiting, or diarrhea after taking Telmabax, you should discuss this with your doctor. Your doctor will decide on further treatment. You should not stop taking Telmabax on your own.

Telmabax is not recommended for use in children and adolescents under 18 years of age.
PL/H/0698/002-003/IA/020
Other medicines and Telmabax
You should tell your doctor or pharmacist about all the medicines you are taking or have recently taken, as well as any medicines you plan to take.
Your doctor may decide to change the dose of these medicines or take other precautions. In some cases, it may be necessary to stop taking one of the medicines. This is especially true for the following medicines taken with Telmabax:
- medicines containing lithium, used to treat certain types of depression;
- medicines that can increase potassium levels in the blood, such as potassium-sparing diuretics, ACE inhibitors, angiotensin II receptor antagonists, non-steroidal anti-inflammatory drugs (NSAIDs, e.g., acetylsalicylic acid or ibuprofen), heparin, immunosuppressive agents (e.g., cyclosporine or tacrolimus), and the antibiotic trimethoprim;
- diuretics, especially when taken in high doses with Telmabax, as they can lead to significant water loss and low blood pressure (hypotension);
- digoxin.
The effect of Telmabax may be reduced when taken with NSAIDs (non-steroidal anti-inflammatory drugs, e.g., acetylsalicylic acid or ibuprofen) or corticosteroids.
Telmabax may enhance the blood pressure-lowering effect of other medicines used to treat high blood pressure or medicines that can cause a decrease in blood pressure (e.g., baclofen, amifostine). Additionally, low blood pressure can be further decreased by: alcohol, barbiturates, narcotics, or antidepressants. The symptom is dizziness when standing up. If you need to adjust the dose of another medicine you are taking while taking Telmabax, you should consult your doctor.
Pregnancy and breastfeeding
Pregnancy
You should inform your doctor if you suspect or plan to become pregnant. Usually, your doctor will advise you to stop taking Telmabax before planned pregnancy or as soon as you become pregnant and will prescribe another medicine instead of Telmabax. It is not recommended to take Telmabax in early pregnancy, and you must not take it after the third month of pregnancy, as it may seriously harm your baby.
Breastfeeding
You should tell your doctor if you are breastfeeding or plan to breastfeed. Telmabax is not recommended during breastfeeding. Your doctor may choose another treatment during breastfeeding, especially in the period of breastfeeding newborns and premature babies.
Driving and using machines
Some patients taking Telmabax may experience dizziness or fatigue. If you experience dizziness or fatigue, you should not drive or operate machinery.
Telmabax contains sorbitol
If you have intolerance to some sugars, you should consult your doctor before taking the medicine.
Telmabax contains sodium
The medicine contains less than 1 mmol (23 mg) of sodium per tablet, which means that the medicine is considered "sodium-free".

3. How to take Telmabax
This medicine should always be taken exactly as your doctor has told you. If you are not sure, you should ask your doctor or pharmacist.
Usually, the recommended dose of Telmabax is one tablet per day. You should take one tablet daily at the same time.
Telmabax can be taken with or without food. The tablets should be swallowed with water or another non-alcoholic liquid. It is important to take Telmabax every day, unless your doctor tells you to stop. If you feel that the effect of Telmabax is too strong or too weak, you should consult your doctor or pharmacist.
In the treatment of high blood pressure, the usual dose of Telmabax is 40 mg once daily for most patients, which provides blood pressure control for more than 24 hours. Your doctor may prescribe a lower dose of 20 mg once daily or a higher dose of 80 mg once daily. Telmabax can also be given in combination with a diuretic, such as hydrochlorothiazide, which enhances the blood pressure-lowering effect of Telmabax.
To reduce the frequency of cardiovascular events, the usual dose of Telmabax is 80 mg once daily. At the beginning of treatment, you should frequently monitor your blood pressure.
In patients with liver problems, the usual dose should not exceed 40 mg once daily.
Taking a higher dose of Telmabax than recommended
If you accidentally take too many tablets, you should immediately contact your doctor or pharmacist or the nearest hospital emergency department.
Missing a dose of Telmabax
You should not worry if you forget to take a dose. You should take it as soon as you remember, and then continue taking the medicine as scheduled. If you do not take a tablet during the day, you should take your usual dose the next day. You should nottake a double dose to make up for a missed dose.
