What is olmesartan, and what is it used for?
Olmesartan is a prescription medicine used to treat high blood pressure (hypertension). By lowering blood pressure, it helps reduce the risk of blood-pressure–related complications such as stroke and heart problems.
How does olmesartan work?
Olmesartan blocks the angiotensin II type 1 (AT1) receptor. That relaxes blood vessels and helps lower blood pressure.
What side effects do people commonly report?
Common side effects can include dizziness and fatigue. Like other medicines in the same drug class, it can also affect kidney function and potassium levels, so clinicians often monitor lab results after starting or changing the dose.
What should patients watch for?
Patients are generally advised to seek medical advice promptly if they have symptoms that may signal low blood pressure (such as fainting), dehydration, or kidney problems (such as reduced urination). Because olmesartan can change potassium levels, it is important not to start potassium supplements or salt substitutes without clinician guidance.
