# HYDROCHLOROTHIAZIDE 12.5 MG + LOSARTAN POTASSIUM 50 MG ## SHORT DESCRIPTION **Hydrochlorothiazide 12.5 mg + Losartan Potassium 50 mg** is a combination medicine used primarily to treat **high blood pressure (hypertension)**. It combines an angiotensin II receptor blocker (ARB), **losartan**, with a thiazide diuretic, **hydrochlorothiazide**. The combination lowers blood pressure through two complementary mechanisms: losartan relaxes blood vessels by blocking angiotensin II, while hydrochlorothiazide helps the body eliminate excess sodium and water through urine. --- ## KEY BENEFITS * Helps lower **high blood pressure**. * Combines two complementary blood-pressure-lowering medicines in one tablet. * Helps relax and widen blood vessels. * Helps remove excess sodium and fluid from the body. * May provide better blood-pressure control when one medicine alone is insufficient. * Convenient **once-daily treatment** for many patients. * Long-term blood-pressure control can help reduce the risk of cardiovascular complications such as stroke and heart disease. --- ## USES / INDICATIONS Hydrochlorothiazide + Losartan may be prescribed for: ### Hypertension * Treatment of **high blood pressure**. * Patients whose blood pressure is not adequately controlled with losartan or another antihypertensive alone. * Patients who require combination therapy for better blood-pressure control. ### Cardiovascular Risk Management Controlling hypertension may help reduce the long-term risk of: * Stroke * Heart attack * Heart failure * Kidney complications associated with uncontrolled hypertension > This medicine is intended for blood-pressure control and is **not a treatment for an immediate hypertensive emergency**. --- ## HOW IT WORKS ### Losartan Potassium Losartan is an **angiotensin II receptor blocker (ARB)**. Angiotensin II normally causes blood vessels to constrict and promotes sodium and water retention. Losartan blocks the **AT1 receptor**, reducing these effects. This results in: * Relaxation of blood vessels * Reduced blood pressure * Reduced aldosterone activity * Reduced sodium and fluid retention ### Hydrochlorothiazide Hydrochlorothiazide is a **thiazide diuretic**. It increases the excretion of: * Sodium * Chloride * Water This reduces excess fluid volume and contributes to lower blood pressure. ### Combined Effect **Losartan → relaxes blood vessels** **Hydrochlorothiazide → removes excess sodium and water** Together, these effects can provide stronger blood-pressure reduction than either component alone in appropriate patients. --- ## DOSAGE & ADMINISTRATION * Take Hydrochlorothiazide 12.5 mg + Losartan 50 mg **exactly as prescribed**. * It is commonly taken **once daily**. * Take the tablet at approximately the same time every day. * It can generally be taken **with or without food**. * Because hydrochlorothiazide increases urine production, taking it earlier in the day may help reduce nighttime urination. * Swallow with water. ### Dose Adjustment The appropriate dose depends on: * Blood-pressure response * Kidney function * Electrolyte levels * Previous antihypertensive treatment * Other medicines being used Your doctor may adjust the dose or use the individual components separately if necessary. ### Monitoring Your healthcare professional may monitor: * Blood pressure * Kidney function * Potassium * Sodium * Other electrolytes ### Missed Dose Take the missed dose when remembered unless it is nearly time for the next dose. **Do not take two doses together.** --- ## SIDE EFFECTS ### Common Side Effects Possible side effects include: * Dizziness * Headache * Fatigue * Increased urination * Low blood pressure * Mild gastrointestinal discomfort ### Hydrochlorothiazide-Related Effects Hydrochlorothiazide may cause changes in electrolyte levels, including: * Low sodium * Low potassium * Increased calcium * Increased uric acid * Changes in blood glucose ### Losartan-Related Effects Losartan may cause: * Dizziness * Fatigue * Low blood pressure * Increased potassium levels * Changes in kidney function ### Serious Side Effects Seek medical attention for: * Severe dizziness or fainting * Significant weakness * Irregular heartbeat * Severe dehydration * Swelling of the face, lips, tongue, or throat * Difficulty breathing * Significant reduction in urine output --- ## PRECAUTIONS & WARNINGS ### Pregnancy **Losartan should not be used during pregnancy**, particularly during the second and third trimesters, because medicines that act on the renin-angiotensin system can cause serious fetal harm. If pregnancy occurs, contact your healthcare professional promptly. ### Kidney Disease Tell your doctor if you have kidney disease. Kidney function should be assessed and monitored when appropriate. ### Liver Disease Patients with significant liver impairment may require special consideration and dose adjustment. ### Electrolyte Imbalance Hydrochlorothiazide can alter sodium, potassium, and other electrolyte levels. Seek medical advice if you develop: * Severe weakness * Muscle cramps * Confusion * Abnormal heartbeat ### Dehydration Excessive fluid loss from vomiting, diarrhea, sweating, or inadequate fluid intake can cause low blood pressure and kidney problems. ### Diabetes Hydrochlorothiazide may affect blood glucose levels. Patients with diabetes may require closer monitoring. ### Gout Hydrochlorothiazide can increase **uric acid levels** and may worsen gout in susceptible individuals. ### Sun Sensitivity Hydrochlorothiazide can increase sensitivity to sunlight and may increase the risk of certain skin cancers with long-term exposure. Use appropriate sun protection and discuss unusual or persistent skin lesions with your healthcare professional. --- ## DRUG INTERACTIONS ### Potassium Supplements and Potassium-Sparing Medicines Losartan can increase potassium levels. Use caution with: * Potassium supplements * Potassium-containing salt substitutes * Spironolactone * Amiloride * Triamterene These combinations may cause **hyperkalemia**. ### NSAIDs Medicines such as: * Ibuprofen * Naproxen * Diclofenac may reduce the blood-pressure-lowering effect and increase the risk of kidney problems, particularly in dehydrated patients or those with existing kidney disease. ### Lithium Losartan and hydrochlorothiazide can increase **lithium concentrations**, potentially causing lithium toxicity. ### Other Blood Pressure Medicines Combining this medicine with other antihypertensive medicines may cause excessive blood-pressure reduction. ### Diabetes Medicines Hydrochlorothiazide may affect blood glucose control and may alter the requirements for certain diabetes medicines. ### Other Diuretics Combining diuretics may increase fluid and electrolyte loss. ### Corticosteroids Certain corticosteroids may increase the risk of **low potassium** when used with hydrochlorothiazide. Always inform your doctor or pharmacist about all prescription medicines, OTC medicines, vitamins, and herbal supplements you take. --- ## STORAGE INFORMATION * Store according to the **manufacturer's instructions**. * Keep tablets in their original packaging. * Protect from excessive heat, moisture, and direct sunlight. * Keep the container tightly closed. * Keep out of reach of children and pets. * Do not use after the expiry date. * Do not use tablets if the packaging is damaged or the tablets appear abnormal. --- ## PRESCRIPTION STATUS **Hydrochlorothiazide 12.5 mg + Losartan Potassium 50 mg is generally a prescription medicine.** Blood pressure, kidney function, and electrolyte levels may need monitoring during treatment. --- ## GENUINE MEDICINE ASSURANCE When purchasing Hydrochlorothiazide 12.5 mg + Losartan Potassium 50 mg, ensure that: * The medicine comes in **original, sealed manufacturer packaging**. * Both active ingredients and strengths are clearly stated. * The manufacturer's information is present. * The **batch/lot number and expiry date** are visible. * Packaging shows no signs of tampering. * Tablets have the appearance described by the manufacturer. * The medicine is purchased from a **licensed pharmacy or authorized medicine supplier**. * The product matches the prescribed strength and formulation.
