PRESITON 50 MG

# SPIRONOLACTONE 50 MG ## SHORT DESCRIPTION **Spironolactone 50 mg** is a prescription medicine known as a **potassium-sparing diuretic** and **aldosterone antagonist**. It helps the body remove excess sodium and water while reducing potassium loss. It is commonly used for **high blood pressure, fluid retention (edema), heart failure, hyperaldosteronism**, and certain conditions associated with excess androgen activity, depending on the patient's medical condition and local treatment guidelines. --- ## KEY BENEFITS * Helps reduce **excess fluid retention and swelling**. * Helps lower **blood pressure** in appropriate patients. * Supports treatment of certain types of **heart failure**. * Helps reduce potassium loss associated with aldosterone activity. * Can be used to treat **hyperaldosteronism**. * Has anti-androgen effects and may be prescribed for certain hormone-related conditions under specialist supervision. --- ## USES / INDICATIONS Spironolactone 50 mg may be prescribed for: 1. **Hypertension (high blood pressure)** 2. **Edema/fluid retention**, including that associated with heart failure, liver disease, or certain kidney conditions 3. **Heart failure with reduced ejection fraction**, when clinically appropriate 4. **Primary hyperaldosteronism** 5. Certain cases of **low potassium levels** when other measures are inadequate 6. Certain hormone-related conditions where its anti-androgen effects are clinically useful The approved uses and dosing vary according to the country, formulation, and patient's condition. --- ## HOW IT WORKS Spironolactone blocks the action of **aldosterone**, a hormone that normally causes the kidneys to retain sodium and water while excreting potassium. By blocking aldosterone, spironolactone: * Increases sodium and water excretion. * Helps reduce fluid accumulation. * Lowers blood volume and can help reduce blood pressure. * Reduces potassium loss compared with many other diuretics. * Produces anti-androgen effects by interfering with androgen activity. Because it can increase potassium levels, **potassium and kidney function monitoring** may be necessary. --- ## DOSAGE & ADMINISTRATION ### Typical Adult Use The appropriate dose depends on the condition being treated, kidney function, potassium level, age, and response to treatment. A **50 mg tablet** may be taken once daily or divided into doses depending on the prescribed regimen. * Take exactly as prescribed. * Take at approximately the same time each day. * It can generally be taken with or without food, but taking it consistently in relation to meals may help maintain predictable absorption. * Because it is a diuretic, taking it earlier in the day may reduce nighttime urination when appropriate. ### Missed Dose Take the missed dose when remembered unless it is close to the next scheduled dose. **Do not take two doses together.** ### Monitoring Your healthcare professional may monitor: * Blood potassium * Kidney function * Blood pressure * Fluid balance * Other electrolytes Do not change the dose based on your potassium level without medical advice. --- ## SIDE EFFECTS ### Common Side Effects Possible side effects include: * Increased urination * Dizziness * Headache * Nausea * Vomiting * Diarrhea or stomach discomfort * Fatigue * Breast tenderness ### Hormonal Side Effects Because spironolactone has anti-androgenic effects, it can cause: * **Breast enlargement (gynecomastia)** in some men * Breast tenderness * Menstrual irregularities * Changes in libido * Erectile or sexual difficulties ### Serious Side Effects Seek medical attention for: * Severe muscle weakness * Abnormal heartbeat or palpitations * Severe dizziness or fainting * Significant reduction in urination * Confusion or severe weakness * Signs of a serious allergic reaction These can sometimes indicate **high potassium levels or significant kidney problems**. --- ## PRECAUTIONS & WARNINGS ### Hyperkalemia The most important concern with spironolactone is **high blood potassium (hyperkalemia)**. Risk is increased in people with: * Kidney impairment * Diabetes with kidney involvement * Heart failure * High baseline potassium * Certain interacting medicines Symptoms of severe hyperkalemia can include weakness, abnormal heartbeat, or potentially life-threatening cardiac disturbances. ### Kidney Disease Spironolactone may not be appropriate in significant kidney impairment. Kidney function should be assessed before and during treatment when clinically indicated. ### Potassium Supplements Do not take potassium supplements or potassium-containing salt substitutes unless specifically recommended by your healthcare professional. ### Dehydration and Low Blood Pressure Excessive fluid loss can cause: * Dizziness * Low blood pressure * Weakness * Dehydration Seek medical advice if significant vomiting, diarrhea, or dehydration occurs. ### Pregnancy Spironolactone is generally **not recommended during pregnancy** unless specifically determined to be necessary by a healthcare professional. Its anti-androgenic effects may pose potential concerns for a developing male fetus. ### Breastfeeding Spironolactone and its metabolites can enter breast milk. Discuss treatment with your healthcare professional if you are breastfeeding. ### Menstrual and Hormonal Effects Women may experience irregular periods or breast tenderness. Men may develop gynecomastia with longer-term treatment. --- ## DRUG INTERACTIONS ### ACE Inhibitors and ARBs Medicines such as: * Enalapril * Lisinopril * Ramipril * Losartan * Valsartan can increase potassium levels when combined with spironolactone. ### Potassium Supplements Potassium supplements and potassium-containing salt substitutes may significantly increase the risk of hyperkalemia. ### Other Potassium-Sparing Diuretics Combining spironolactone with medicines such as **amiloride or triamterene** can substantially increase potassium levels. ### NSAIDs Medicines such as: * Ibuprofen * Naproxen * Diclofenac may reduce the diuretic effect of spironolactone and can increase the risk of kidney problems and hyperkalemia in susceptible patients. ### Digoxin Spironolactone can affect digoxin handling and may interfere with some laboratory measurements of digoxin. Monitoring may be necessary. ### Lithium Diuretics can increase lithium concentrations and potentially increase the risk of lithium toxicity. ### Certain Antibiotics and Other Medicines Some medicines, including **trimethoprim-containing products**, can increase the risk of hyperkalemia when combined with spironolactone. Always inform your healthcare professional about all prescription medicines, OTC products, vitamins, and herbal supplements you use. --- ## STORAGE INFORMATION * Store according to the manufacturer's instructions. * Keep at room temperature unless the product label states otherwise. * Protect from excessive heat, moisture, and direct sunlight. * Keep tablets in their original packaging. * Keep out of reach and sight of children. * Do not use after the expiry date. * Do not use tablets if the packaging is damaged or shows signs of deterioration. --- ## PRESCRIPTION STATUS **Prescription-only medicine.** Spironolactone should be used under medical supervision because it can cause **high potassium levels, changes in kidney function, low blood pressure, and clinically significant drug interactions**. --- ## GENUINE MEDICINE ASSURANCE When purchasing **Spironolactone 50 mg**, obtain it from a **licensed pharmacy or authorized medicine supplier**.
