If you’ve recently been prescribed Telmisartan 40mg, you might be curious about how it works and what you should expect in the first few weeks. Telmisartan is a widely used treatment for high blood pressure (hypertension) in the UK, and it plays a key role in preventing strokes, heart attacks and kidney problems.
What Is Telmisartan?
Telmisartan is part of a class of medicines called angiotensin II receptor blockers (ARBs). It works by blocking the action of a hormone that narrows blood vessels. This allows your blood vessels to relax and widen, making it easier for blood to flow through and reducing your blood pressure.
ARBs like Telmisartan are often used as alternatives to ACE inhibitors, especially in patients who experience a persistent dry cough on those medicines. Telmisartan is considered to be effective and generally well-tolerated.
How to take Telmisartan
Most people start with 40mg once a day, ideally at the same time each day. It can be taken with or without food. Some individuals may require a higher dose (up to 80mg) if their blood pressure is not adequately controlled after a few weeks.
It’s important to keep taking Telmisartan even if you feel fine. High blood pressure often has no symptoms, so you might not notice a difference day-to-day.
Common side effects
Like all medicines, Telmisartan can cause side effects, although not everyone gets them. Some people may experience:
- Dizziness or light-headedness, especially when standing up
- Headache
- Back pain
- Fatigue
- Nausea
Rare side effects may include changes in kidney function or increased potassium levels. Routine blood tests may be requested to monitor these effects.
Lifestyle tips while on Telmisartan
- Stay hydrated, but avoid excessive salt intake
- Eat a heart-healthy diet, rich in fruit, vegetables and wholegrains
- Maintain a healthy weight and stay physically active
- Avoid alcohol or non-prescription medications that can interfere with blood pressure control
- Quit smoking if applicable, as it greatly increases cardiovascular risk
Monitoring progress
It may take a few weeks for Telmisartan to have its full effect. During this time, your doctor may check your blood pressure, kidney function and potassium levels. Let your GP know if you experience any side effects or if your blood pressure remains high.
Final thoughts
Starting Telmisartan is a positive step towards better heart health. Be patient as your body adjusts, and always consult your GP or pharmacist if you’re unsure about anything. With the right support and a healthy routine, Telmisartan can help keep your blood pressure under control and significantly reduce long-term health risks.
