Olmesar A is a combination medication containing Amlodipine (5 mg) and Olmesartan (20 mg). It is commonly prescribed to manage high blood pressure (hypertension).

• How it works: Amlodipine is a calcium channel blocker that helps relax blood vessels, making it easier for your heart to pump blood. Olmesartan is an angiotensin receptor blocker (ARB) that also helps widen blood vessels and reduce blood pressure.

• Use: Taking Olmesar A helps lower your blood pressure, reducing the risk of heart attacks, strokes, and kidney problems.

• Regarding your headache: Headaches can sometimes be a symptom of high blood pressure or a side effect of medication. Since you have been taking Olmesar A for three years, it’s important to monitor your blood pressure regularly. If your headaches persist or worsen, you should consult your doctor to check if your blood pressure is well controlled or if any adjustments to your treatment are needed.

Remember, never stop or change your medication without medical advice. If you experience severe headaches, dizziness, or other concerning symptoms, seek medical attention promptly.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
