What is Telmisartan?
Telmisartan is a prescription medicine used to treat high blood pressure (hypertension). It belongs to a group of medicines called angiotensin II receptor blockers (ARBs).
High blood pressure is a common condition where the force of blood against the walls of your arteries remains too high. Over time, this increased pressure can damage blood vessels and increase the risk of serious health problems such as heart attack, stroke, kidney disease and heart failure.
Telmisartan works by relaxing and widening your blood vessels. This allows blood to flow more easily through your body and reduces the workload on your heart.
Because high blood pressure often causes no noticeable symptoms, treatment is important to protect your heart, brain and kidneys from long term damage.
What is it used for?
Telmisartan is used to treat:
- High blood pressure (hypertension)
- To reduce the risk of heart attack, stroke or cardiovascular death in high risk adults
Lowering blood pressure helps reduce the risk of long term complications such as:
- Heart disease
- Stroke
- Kidney damage
- Circulation problems
Telmisartan may also be prescribed for people who have a higher risk of cardiovascular events due to conditions such as diabetes, previous heart disease or vascular disease.
By controlling blood pressure and improving blood vessel function, Telmisartan helps protect your cardiovascular system.
How does the product work?
Telmisartan works by blocking the effects of angiotensin II, a hormone that narrows blood vessels.
Angiotensin II normally causes:
- Blood vessels to tighten
- Increased blood pressure
- Increased strain on the heart
Telmisartan blocks angiotensin II from attaching to its receptors in the blood vessels. This causes the blood vessels to relax and widen.
As a result, Telmisartan:
- Lowers blood pressure
- Improves blood flow
- Reduces strain on the heart
- Helps protect the kidneys
Because it specifically targets the angiotensin receptor system, Telmisartan lowers blood pressure without affecting heart rate.
Who should not use the product?
You should not use Telmisartan if:
- You are allergic to telmisartan or any of its ingredients
- You are more than three months pregnant
- You have severe liver disease
- You have bile duct obstruction
- You have diabetes or kidney impairment and are taking aliskiren
Telmisartan should be used with caution if you:
- Have kidney disease
- Have liver problems
- Have severe dehydration
- Have low blood pressure
- Are taking other blood pressure medicines
Always inform your doctor about your full medical history and medications.
Pregnancy and breastfeeding
Telmisartan must not be used during pregnancy, particularly after the first trimester, as it may harm an unborn baby.
If you become pregnant while taking Telmisartan, stop taking the medication and contact your doctor immediately.
Telmisartan is generally not recommended while breastfeeding. Alternative treatments may be considered.
How to use and dosage
Always take Telmisartan exactly as prescribed.
The usual dose is:
- One tablet once daily
It should be taken:
- At the same time each day
- With water
- With or without food
Your doctor may adjust the dose depending on your blood pressure response.
Because high blood pressure often has no symptoms, it is important to continue taking Telmisartan even if you feel well.
Do not stop taking Telmisartan without medical advice.
Possible side effects
Like all medicines, Telmisartan may cause side effects, although not everyone experiences them.
Common side effects include:
- Dizziness
- Low blood pressure
- Back pain
- Diarrhoea
- Fatigue
Less common side effects may include:
- Kidney function changes
- High potassium levels

Important safety information
Before starting Telmisartan, tell your doctor if you:
- Have kidney disease
- Have liver problems
- Have heart disease
- Are on a low salt diet
- Take potassium supplements
- Take diuretics (water tablets)
Telmisartan can increase potassium levels in the blood, particularly when combined with certain medications.
Regular monitoring may be recommended during long term treatment.
Lifestyle measures such as reducing salt intake, maintaining a healthy weight and exercising regularly can also help control blood pressure.
When to seek medical help
Seek urgent medical attention if you experience:
- Severe dizziness or fainting
- Swelling of the face, lips or throat
- Difficulty breathing
- Chest pain
Contact your doctor if:
- Your blood pressure remains high
- You experience persistent dizziness
- You notice unusual swelling or weakness
- You experience significant side effects
If you are unsure whether your symptoms are related to your blood pressure medication, you can book a secure video consultation with a licensed doctor via Transtoyou for personalised advice. If symptoms are severe or sudden, seek urgent medical care immediately.

Telmisartan is used for:
- Treatment of essential high blood pressure (hypertension) in adults
- Reduction of cardiovascular events such as heart attack or stroke in adults at high risk of cardiovascular disease
High blood pressure often causes no symptoms but can damage blood vessels and organs such as the heart, brain and kidneys if left untreated. Lowering blood pressure helps reduce the risk of these complications.
