Olmezest H 40 Tablet belongs to a group of medications called 'anti-hypertensives' primarily used to treat high blood pressure (hypertension). High blood pressure is a chronic condition in which the blood's force against the artery wall is high. As a result, it increases the risk of heart-related diseases like heart attack, heart failure, stroke, irregular heartbeat, and other complications.

Olmezest H 40 Tablet is a combination of two medicines: Olmesartan medoximil and Hydrochlorothiazide. Olmesartan medoximil is an angiotensin receptor blocker (ARB) that blocks the hormone angiotensin, thereby relaxing and widening the narrowed blood vessels. This allows the blood to flow more smoothly in the blood vessels, and the heart can pump more efficiently. On the other hand, Hydrochlorothiazide is a diuretic or water pill that works by removing extra water/fluid and certain electrolyte overload from the body. Together, Olmezest H 40 Tablet lowers blood pressure and fluid overload.

You can take Olmezest H 40 Tablet with food or without food with a glass of water. Do not chew, bite, or break it. Your doctor will advise you on how often you take your tablets based on your medical condition. In some cases, you may experience nausea, upset stomach, dehydration, headache, diarrhoea, electrolyte imbalance, dizziness, and decreased blood pressure. Most of these side effects of Olmezest H 40 Tablet do not require medical attention and gradually resolve over time. However, if the side effects are persistent, reach out to your doctor.

Try not to stop taking this medicine of your own. Let your doctor know about this, as it may cause a rise in blood pressure and increase heart disease and stroke risk. Inform your doctor if you are suffering from kidney, liver, or heart disease or are diabetic. If you are pregnant or breastfeeding, do not take Olmezest H 40 Tablet as it is a category D pregnancy drug and may harm the baby. Do not use Olmezest H 40 Tablet if you cannot urinate, are dehydrated, have low blood pressure (hypotension), and have or have had cardiogenic shock (sudden stopping of blood flow to the heart). Please tell your doctor if you are taking any other medicines or are allergic to this medicine.

Olmezest H 40 Tablet is primarily used to treat high blood pressure. Olmezest H 40 Tablet is a combination of two medicines: Olmesartan and Hydrochlorothiazide. Olmesartan medoximil is a prodrug and breaks down into active form, i.e., olmesartan once absorbed in the GIT (Gastrointestinal tract). It is an angiotensin receptor blocker (ARB) that blocks the hormone angiotensin and relaxes blood vessels. This allows the blood to flow more smoothly in the blood vessels, and the heart can pump more efficiently. Hydrochlorothiazide (diuretic or water pill); removes extra water and certain electrolytes from the body. Together, both lower fluid overload, and blood pressure, improve blood flow and reduce the future risk of a heart attack.

Hypertension: It is a chronic condition when blood pressure is too high. This condition can lead to hardened arteries (blood vessels), decreasing the blood and oxygen flow to the heart. Blood pressure is the measurement of the force our heart uses to pump blood to all body parts. Raised blood pressure can cause chest pain (angina) and heart attack (when blood supply to the heart is blocked). Additionally, high blood pressure also causes brain damage (stroke) and kidney failure. High blood pressure can be diagnosed with the help of a blood pressure monitor or sphygmomanometer. Systolic pressure is the pressure when the heart pumps blood out. On the other hand, diastolic pressure is the pressure when your heart is at the resting stage between heartbeats. If your blood pressure is 140/90 mm of Hg, it means the systolic pressure is 140 mm of Hg, and diastolic pressure is 90 mm of Hg. Ideal blood pressure should be between 90/60 mm of Hg and 120/80 mm of Hg.
