Read all of this leaflet carefully before you start taking this medicine because it contains important information for you.
Contents of the pack and other information
Telmisartan/Hydrochlorothiazide Viatris is a combination of two active substances, telmisartan and hydrochlorothiazide in one tablet. Both active substances help to control high blood pressure.
Telmisartan blocks the effect of angiotensin II, so that the blood vessels relax and your blood pressure is reduced.
High blood pressure, if left untreated, can damage the blood vessels of various organs, which in some cases can lead to a heart attack, heart failure or kidney failure, stroke or blindness. Usually, there are no symptoms of high blood pressure before damage occurs. Therefore, it is important to regularly check your blood pressure to ensure it is within the normal range.
Telmisartan/Hydrochlorothiazide is used to treat 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 with telmisartan and hydrochlorothiazide separately.
Do not take Telmisartan/Hydrochlorothiazide Viatris
If any of the above applies to you, tell your doctor or pharmacist before taking Telmisartan/Hydrochlorothiazide.
Warnings and precautions
Consult your doctor before starting to take Telmisartan/Hydrochlorothiazide if you suffer from or have suffered from any of the following disorders or diseases:
Consult your doctor before starting to take telmisartan/hydrochlorothiazide:
Your doctor may need to check your kidney function, blood pressure, and blood electrolyte levels (e.g., potassium) at regular intervals.
See also the information under the heading "Do not take Telmisartan/Hydrochlorothiazide Viatris".
Tell your doctor if you experience abdominal pain, nausea, vomiting, or diarrhea after taking telmisartan. Your doctor will decide whether to continue treatment. Do not stop taking telmisartan on your own.
If you are pregnant, think you may be pregnant, or are planning to become pregnant, tell your doctor. Telmisartan/Hydrochlorothiazide is not recommended during pregnancy (first 3 months) and should not be taken after the third month of pregnancy 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, somnolence, restlessness, pain or muscle cramps, nausea, vomiting, muscle fatigue, and an abnormally fast heart rate (more than 100 beats per minute). If you experience any of these symptoms, tell your doctor.
You should also tell your doctor if you experience increased sensitivity of the skin to the sun with symptoms of sunburn (such as redness, itching, swelling, blistering) that appear more quickly than usual.
If you are going to have surgery (including dental surgery) or anesthesia, tell your doctor that you are taking Telmisartan/Hydrochlorothiazide.
Telmisartan/Hydrochlorothiazide may be less effective in reducing blood pressure in black patients.
Children and adolescents
Telmisartan/Hydrochlorothiazide is not recommended for use in children and adolescents up to 18 years of age.
Other medicines and Telmisartan/Hydrochlorothiazide Viatris
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. Your doctor may need to change the dose of those other medicines or take other precautions. In some cases, it may be necessary to stop taking some of these medicines, especially if you are taking any of the following medicines with Telmisartan/Hydrochlorothiazide:
Telmisartan/Hydrochlorothiazide may increase the ability of other medicines to lower blood pressure or of medicines that may potentially lower blood pressure (e.g., baclofen, amifostine).
Additionally, the decrease in blood pressure may be enhanced by alcohol, barbiturates, narcotics, or antidepressants. You may notice this effect as dizziness when standing up. You should tell your doctor about the need to adjust the dose of your other medicines while taking Telmisartan/Hydrochlorothiazide.
The effect of Telmisartan/Hydrochlorothiazide may be reduced when taking NSAIDs (non-steroidal anti-inflammatory drugs, e.g., aspirin or ibuprofen).
You can take Telmisartan/Hydrochlorothiazide with or without food.
Avoid drinking alcohol until you have talked to your doctor. Alcohol may further lower your blood pressure and/or increase the risk of feeling dizzy or weak.
Pregnancy and breastfeeding
Pregnancy
Tell your doctor if you are pregnant, think you may be pregnant, or are planning to become pregnant. Your doctor will normally advise you to stop taking Telmisartan/Hydrochlorothiazide before you become pregnant or as soon as you find out you are pregnant, and will recommend that you take another blood pressure medicine instead. Telmisartan/Hydrochlorothiazide is not recommended during pregnancy and should not be taken after the third month of pregnancy as it may cause serious harm to your baby.
Breastfeeding
Tell your doctor if you are about to start or are already breastfeeding, as Telmisartan/Hydrochlorothiazide is not recommended for use during breastfeeding. Your doctor may decide to give you a different treatment that is more suitable if you want to breastfeed.
Driving and using machines
Some patients feel dizzy or tired when taking Telmisartan/Hydrochlorothiazide. If you feel dizzy or tired, do not drive or use machines.
Follow exactly the instructions of administration of this medicine given to you by your doctor. If you are not sure, ask your doctor or pharmacist again.
The recommended dose of Telmisartan/Hydrochlorothiazide is one tablet per day. Try to take one tablet each day at the same time. You can take Telmisartan/Hydrochlorothiazide with or without food. The 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 to stop.
If your liver is not working properly, the usual dose should not exceed 40 mg/12.5 mg once a day.
If you take more Telmisartan/Hydrochlorothiazide Viatris than you should
If you accidentally take too many tablets, you may experience symptoms such as low blood pressure and fast heart rate. Slow heart rate, dizziness, vomiting, and reduced kidney function including kidney failure have also been reported. Due to the hydrochlorothiazide component, you may also experience very low blood pressure and low potassium levels in the blood, which can lead to nausea, somnolence, and muscle cramps and/or irregular heartbeats associated with concomitant use of medicines such as digitalis or certain antiarrhythmic treatments. Contact your doctor or pharmacist or the nearest hospital emergency department immediately.
In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicology Information Service, telephone 91 562 04 20, indicating the medicine and the amount taken.
If you forget to take Telmisartan/Hydrochlorothiazide Viatris
If you forget to take your medicine, do not worry. Take the dose as soon as you remember and continue as before. If you do not take your tablet one day, take your normal dose the next day. Do not take a double dose to make up for forgotten doses.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
