What is OLmesar H 40 Tablet?

OLmesar H 40 Tablet is a prescription blood pressure medicine that combines olmesartan medoxomil and hydrochlorothiazide in one tablet. Each OLmesar H 40 Tablet contains olmesartan medoxomil 40 mg and hydrochlorothiazide 12.5 mg. It belongs to the ARB plus thiazide diuretic class and is used to help lower high blood pressure (hypertension), which can reduce the risk of stroke and other heart-related problems when taken as prescribed.

How it works: Olmesartan blocks a hormone signal that tightens blood vessels, so the vessels relax and blood can flow more easily. Hydrochlorothiazide helps your body remove extra salt and water through urine, which lowers blood volume and helps this tablet reduce blood pressure.

Why choose OLmesar H 40 Tablet?

OLmesar H 40 Tablet is the higher-strength version of this combination, with olmesartan 40 mg plus hydrochlorothiazide 12.5 mg in each tablet. Because of the 40 mg olmesartan dose, it is usually chosen for patients whose blood pressure needs stronger control or who are moving up from a lower dose after a doctor’s review. It is not meant for self-adjusting treatment, since the right strength depends on your blood pressure response, kidney function, and other medicines.

Uses of OLmesar H 40 Tablet

  • Treatment of high blood pressure (hypertension)
  • May help reduce risk of stroke and heart complications from uncontrolled blood pressure
  • Used when a single medicine is not enough to control blood pressure
  • May be prescribed when a doctor wants the combined effect of an ARB and a diuretic

How to take OLmesar H 40 Tablet

  • Swallow the tablet whole with a glass of water; do not crush, chew, or split unless your doctor or pharmacist tells you to.
  • Take OLmesar H 40 Tablet at the same time each day to help you remember your dose.
  • Because it contains hydrochlorothiazide, many people take it in the morning to avoid waking up at night to urinate.
  • You may take it with or without food.
  • Rise slowly from sitting or lying positions, especially when you first start this tablet, because it can lower blood pressure and cause dizziness.
  • Keep drinking fluids as advised by your doctor, especially in hot weather or if you sweat a lot.

OLmesar H 40 Tablet dosage

Each OLmesar H 40 Tablet provides olmesartan medoxomil 40 mg and hydrochlorothiazide 12.5 mg per tablet. The usual frequency is once daily, but the exact dose, timing, and whether this is the right strength for you must be decided by your doctor. Do not take more than one tablet in 24 hours unless your prescriber specifically instructs you to do so.

Do not change your dose or stop the medicine without speaking to your doctor.
