Olkem-40 CT Tablet belongs to the class of medicines called antihypertensives primarily used to treat high blood pressure. Hypertension or high blood pressure is a chronic condition in which the force exerted by the blood against the artery wall is high. As a result, it leads to heart diseases, irregular heartbeat, and other complications.

Olkem-40 CT Tablet is a combination of two medicines namely: Olmesartan medoxomil and Chlorthalidone. Olmesartan medoxomil is an angiotensin receptor blocker (ARB) which works by blocking the hormone angiotensin, thereby relaxing blood vessels. This allows the blood to flow more smoothly and the heart to pump more efficiently. Chlorthalidone is a diuretic or water pills that removes extra water and certain electrolytes from the body. Together it lowers fluid overload, blood pressure and improves blood flow.

You can take Olkem-40 CT Tablet with food or without food. It should be swallowed whole with a glass of water. Do not chew, bite, or break it. Your doctor will advise you how often you take your tablets based on your medical condition. In some cases, you may experience headache, nausea, or dizziness. Most of these side effects of Olkem-40 CT 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 can increase the risk of getting heart diseases and stroke. Inform your doctor if you are suffering from any kidney or liver or heart disease or are diabetic.

Olkem-40 CT Tablet is a combination medication, generally used when a single medicine is not effective in controlling blood pressure. Olkem-40 CT Tablet is used to treat hypertension, where Olmesartan medoxomil works by relaxing the blood vessels. On the other hand, Chlorthalidone being diuretic works by increasing the amount of urine that is passed out from the kidneys and hence lowering the blood pressure. Together it lowers the overall raised blood pressure and reduces the risk of having a heart attack, stroke, or kidney problems.
