Telmisartan?

Telmisartan is an angiotensin II receptor blocker (ARB) used to treat high blood pressure (hypertension). It’s sold under brand names like Micardis and is available as a generic. It’s often used alone or with other antihypertensives.

How it works (very simply)
- Blocks the effects of angiotensin II on its type 1 receptor, which relaxes blood vessels and lowers blood pressure.

Typical dosing
- Hypertension: usually 40 mg once daily, may be increased to 80 mg once daily if needed.
- Can be taken with or without food.
- Max daily dose generally 80 mg.

Who shouldn’t take it
- Pregnancy: can harm an unborn baby; discontinue if you become pregnant.
- Caution in breastfeeding; discuss with a clinician.
- Severe liver impairment or significant kidney disease: use under medical supervision; dosing and safety may vary.
- Angioedema history with ACE inhibitors or ARBs requires a clinician’s guidance.

Common side effects
- Dizziness or lightheadedness (especially after starting or increasing the dose)
- Fatigue, back pain, or upper respiratory infections
- Hyperkalemia (high potassium) in some people
- Rare: angioedema (swelling of face, lips, tongue)

Serious but less common risks
- Severe hyperkalemia
- Kidney function impact (monitor creatinine/electrolytes if you have kidney disease)

Drug interactions and safety notes
- NSAIDs (e.g., ibuprofen) can reduce BP-lowering effects and affect kidney function; use caution.
- Drugs that raise potassium (potassium-sparing diuretics like spironolactone or potassium supplements) can increase risk of high potassium.
- Avoid combining with other ARBs or ACE inhibitors unless directed by a clinician.
- Check with your prescriber if you take lithium or have significant kidney disease.

Monitoring
- Blood pressure regularly.
- Periodic blood tests for kidney function and potassium levels, especially after starting or adjusting the dose or if you have kidney disease or take other meds that affect potassium.

If you’d like, tell me:
- Are you asking about a starting dose for you or someone else?
- Any other meds you’re taking (to check for interactions)?
- Any specific concern (side effects, pregnancy, kidney/liver issues)?

I can tailor the info to your situation.
