Olmezest 40 contains Olmesartan (40mg). It belongs to the Angiotensin receptor blocker / ACE inhibitor class of medicines.
Olmezest 40 Tablet is used in the treatment of high blood pressure.
Olmezest 40 Tablet is an angiotensin receptor blocker (ARB). It relaxes blood vessel by blocking the action of a chemical that usually makes blood vessels tighter. This lowers the blood pressure, allowing the blood to flow more smoothly to different organs and the heart to pump more efficiently.
Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. Olmezest 40 Tablet may be taken with or without food, but it is better to take it at a fixed time.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
Take it as soon as you remember. If your next dose is almost due, skip the one you missed — never take two doses together to catch up.
An overdose of this medicine can cause a severe fall in blood pressure, with dizziness, fainting and a fast or slow pulse. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.
Most side effects of Olmezest are mild and settle as the body adjusts. Reported side effects include:
Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

Stand up slowly for the first few days — dizziness on rising is common when you start or your dose goes up. Stop and seek urgent care if your lips, tongue, face or throat swell, or you have difficulty breathing. A persistent dry, tickly cough can be caused by the ACE inhibitor group; tell your doctor rather than stopping on your own, as an alternative exists. Your doctor will check your kidney function and potassium after starting and after any dose change. Do not use salt substitutes containing potassium without asking your doctor.
Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Must not be used in pregnancy — it can seriously harm the developing baby. Not for people with narrowing of both kidney arteries, or a history of swelling of the face and throat caused by this group of medicines.
Anti-inflammatory painkillers reduce the effect and can harm the kidneys when combined. Potassium supplements, potassium-sparing water tablets and salt substitutes can push potassium too high. Lithium levels rise when taken with these medicines.
Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
