How Olmezest CH 40 Tablet works
Olmesartan prevents angiotensin II from tightening the blood vessels, so they stay relaxed and open. Chlorthalidone makes the kidneys remove extra salt and water, reducing the volume of fluid the heart has to move. The two actions together lower blood pressure.

Frequently asked questions
Is Olmezest CH 40 a prescription medicine?
Yes. It should be taken only on a doctor's prescription, because the dose and the combination need to suit your blood pressure and health conditions.
Can I stop taking Olmezest CH 40 once my blood pressure is normal?
No. Normal readings usually mean the medicine is working. Stopping suddenly can let the pressure climb again, so speak to your doctor before making changes.
What should I do if I miss a dose?
Take it as soon as you remember. If it is almost time for the next dose, skip the missed one and carry on as usual. Do not take a double dose.
Is it safe in pregnancy?
No. Olmesartan-containing medicines can harm an unborn baby, so inform your doctor immediately if you are or may become pregnant.
Why might I get muscle cramps on this tablet?
Chlorthalidone can lower body potassium or sodium, which may lead to cramps. Let your doctor know so that blood levels can be checked.
