OLSAR CH 20/12.5MG TABLET belongs to the class of medicines called ‘Anti-hypertensive’, primarily used to treat hypertension (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 disease, irregular heartbeat, and other complications.

OLSAR CH 20/12.5MG TABLET is a combination of two medicines: Olmesartan and Chlorthalidone. Olmesartan is an angiotensin receptor blocker (ARB) that 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. On the other hand, Chlorthalidone is a diuretic or water pill that removes extra water and certain electrolytes from the body. Together it lowers fluid overload and blood pressure and improves blood flow.

Take OLSAR CH 20/12.5MG TABLET as prescribed by your doctor. Your doctor will advise you on how often you take your tablets based on your medical condition. Sometimes, you may experience headaches, nausea, dizziness, and cold extremes. Most of these side effects of OLSAR CH 20/12.5MG 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. Stopping OLSAR CH 20/12.5MG TABLET abruptly may cause changes in your blood pressure and heart rhythm, cause chest pain, or a heart attack. Your doctor will gradually lower your dose over time to help prevent these symptoms. If you are pregnant or breastfeeding, it is advised to inform your doctor before using OLSAR CH 20/12.5MG TABLET . If you are suffering from kidney, liver, or heart disease or are diabetic, please inform your doctor before taking OLSAR CH 20/12.5MG TABLET . Do not use the OLSAR CH 20/12.5MG TABLET if you cannot urinate, are dehydrated, have low blood pressure (hypotension), or have a cardiogenic shock (sudden stopping of blood flow to the heart). Reducing the amount of table salt (sodium chloride) in your food often relieves the swelling of the body. Please inform your doctor if you are using any prescription and non-prescription medications you are taking, including vitamins and herbal supplements.

OLSAR CH 20/12.5MG TABLET is a combination of two drugs, namely, Olmesartan (blood pressure-lowering agent) and Chlorthalidone (diuretic), primarily used to treat hypertension (high blood pressure). Olmesartan is an angiotensin receptor blocker (ARB) that lower increased blood pressure by blocking a naturally occurring substance known as angiotensin II (that tightens your blood vessels). It allows these constricted blood vessels to relax and therefore helps lower high blood pressure. This allows the blood to flow more smoothly and the heart to pump more efficiently. On the other hand, Chlorthalidone, a diuretic, works by increasing the amount of urine passed out from the kidneys and lowering blood pressure. Together it lowers the overall raised blood pressure and reduces the risk of having a heart attack, stroke, or kidney problems. OLSAR CH 20/12.5MG TABLET is generally used when a single medicine is ineffective in controlling blood pressure.

• Dizziness
• Nausea
• Bradycardia (slow heart rate)
• Cold extremes
• Headache
• Hypotension (low blood pressure)

OLSAR CH 20/12.5MG TABLET should not be given to people allergic to OLSAR CH 20/12.5MG TABLET or any of its ingredients. Let your doctor know if you have low blood pressure (less than 90 mm of Hg) or have had a heart attack, kidney disease, or liver disease. OLSAR CH 20/12.5MG TABLET is contraindicated in people with low blood pressure (hypotension), cardiogenic shock (sudden stopping of blood flow to the heart), and aortic stenosis (heart valve problem). Please inform your doctor before surgery if you are taking OLSAR CH 20/12.5MG TABLET as it needs to be stopped because it might lower the blood pressure further if taken along with local anaesthesia. Pregnant women should discontinue OLSAR CH 20/12.5MG TABLET because it can cause injury and death to the developing fetus. Tell your doctor if you are on low sodium (table salt) diet. Cases of electrolyte imbalance have been observed (like low levels of sodium, potassium, or magnesium in your blood). So your doctor might advise monitoring blood pressure, kidney function test, and electrolytes. Please do not stop taking OLSAR CH 20/12.5MG TABLET on your own, as it may lead to the recurrence of symptoms or worsen the condition.

Drug-Drug Interactions: OLSAR CH 20/12.5MG TABLET may interact with other high blood pressure-lowering pills (enalapril, captopril, lisinopril, ramipril, benazepril, diltiazem, verapamil, amiloride, metoprolol, hydrochlorothiazide, simvastatin, atorvastatin, azilsartan), medicine to treat erectile dysfunction (sildenafil), antibiotics (clarithromycin, erythromycin, rifampicin), antifungal (itraconazole, ketoconazole), anti-epilepsy medications (carbamazepine, phenytoin, phenobarbital, primidone), medicines used to treat asthma (salbutamol, formoterol),  anti-HIV drugs (ritonavir), immune-suppressing drugs (cyclosporine, tacrolimus), and pain killers (ibuprofen, naproxen, diclofenac, aspirin).

Drug-Food Interactions: OLSAR CH 20/12.5MG TABLET severely interacts with grapefruit, grapefruit juices, and St. John’s wort (a plant used to treat depression). Hence it should not be taken with OLSAR CH 20/12.5MG TABLET .

Drug-Disease Interactions: OLSAR CH 20/12.5MG TABLET may interact with disease conditions including low blood pressure (hypotension), heart valve problem (stenosis), cardiogenic shock (when the heart fails to pump required blood to the body), coronary heart disease, liver disease, renal impairment, or heart failure.

Hypertension: The blood exerts increased pressure on the walls of blood vessels leading to hypertension. High blood pressure is expressed as systolic/diastolic pressure. Systolic pressure is the pressure in the arteries when the heart beats or pumps out blood. Diastolic pressure is the pressure in the arteries between the heartbeats. Blood pressure is measured in millimetres of mercury (mmHg) by a blood pressure monitor called a sphygmomanometer. Some of the symptoms are headache, dizziness, nosebleeds, altered vision, chest pain, weakness, and shortness of breath. However, most of the time, the signs and symptoms of hypertension are none.
