SPIROLAC-12.5

# Spironolactone 12.5 mg ## Short Description **Spironolactone 12.5 mg** is a prescription **potassium-sparing diuretic and aldosterone antagonist**. It helps the body remove excess sodium and water while reducing potassium loss. Depending on the patient's condition, it may be used for **heart failure, fluid retention (edema), hypertension, and certain conditions associated with excess aldosterone**. ## Key Benefits * Helps reduce **excess fluid retention and swelling (edema)**. * Helps lower blood pressure in appropriate patients. * Helps reduce the effects of excessive **aldosterone**. * Helps prevent potassium loss associated with some diuretic treatments. * May improve outcomes in selected patients with **heart failure with reduced ejection fraction (HFrEF)**. * Can be used as part of combination treatment when prescribed by a healthcare professional. ## Uses / Indications Spironolactone 12.5 mg may be prescribed for: * **Heart failure**, particularly selected patients with reduced ejection fraction * **Edema** associated with heart, liver, or kidney conditions * **Hypertension**, usually as an additional treatment * **Primary hyperaldosteronism** * Other conditions involving excessive aldosterone, when medically appropriate The 12.5 mg strength may be used as a starting or lower dose in certain patients, depending on kidney function, potassium levels, age, and the indication. ## How It Works Spironolactone blocks the action of **aldosterone** at mineralocorticoid receptors in the kidneys. This causes the kidneys to: * Excrete more **sodium and water** * Retain more **potassium** * Reduce fluid accumulation * Reduce blood pressure in some patients Because it retains potassium, spironolactone can cause **high blood potassium (hyperkalemia)**, which is one of its most important safety considerations. ## Dosage & Administration * Take **Spironolactone 12.5 mg exactly as prescribed**. * The dose and frequency depend on the medical condition and your response to treatment. * It may be taken **with or without food**, but take it consistently in relation to meals. * It may be taken once daily or according to the schedule prescribed by your doctor. * Because it has a diuretic effect, taking it earlier in the day may help reduce nighttime urination. * Do not change the dose or stop treatment without medical advice. * If you miss a dose, take it when remembered unless it is nearly time for the next dose. **Do not double the dose.** Your healthcare professional may monitor **serum potassium and kidney function** before and during treatment. ## Side Effects ### Common Side Effects Possible side effects include: * Increased urination * Dizziness * Headache * Nausea * Stomach discomfort * Fatigue * Breast tenderness * **Breast enlargement in males (gynecomastia)** * Menstrual changes or irregular periods ### Serious Side Effects Seek medical attention if you experience: * Muscle weakness * Severe fatigue * Numbness or tingling * Slow or irregular heartbeat * Fainting * Severe dizziness * Reduced urine output * Severe dehydration * Signs of a serious allergic reaction These symptoms can sometimes indicate **high potassium levels or kidney problems**. ## Precautions & Warnings ### Hyperkalemia Spironolactone can significantly increase potassium levels. The risk is higher in people with kidney impairment or those taking other medicines that increase potassium. Do not routinely use **potassium supplements or potassium-containing salt substitutes** unless specifically recommended by your healthcare professional. ### Kidney Function Tell your doctor if you have kidney disease or reduced kidney function. Spironolactone may require dose adjustment or may not be appropriate in some patients. ### Blood Pressure Spironolactone can lower blood pressure. Dizziness or fainting may occur, particularly when starting treatment or when combined with other antihypertensive medicines. ### Hormonal Effects Because spironolactone has anti-androgenic effects, it may cause: * Breast tenderness or enlargement * Menstrual irregularities * Changes in sexual function Tell your healthcare professional if these effects become troublesome. ### Pregnancy Spironolactone is generally **not recommended during pregnancy for routine hypertension or edema**, and its anti-androgenic effects raise particular concerns for a developing male fetus. Discuss pregnancy or plans for pregnancy with your doctor before using it. ## Drug Interactions Spironolactone can interact with several medicines, including: * **ACE inhibitors** such as enalapril or lisinopril — increased risk of hyperkalemia. * **ARBs** such as losartan or valsartan — increased risk of hyperkalemia. * **Potassium supplements and potassium-containing salt substitutes** — may cause dangerously high potassium. * **Potassium-sparing diuretics** such as amiloride or triamterene — increased risk of hyperkalemia. * **NSAIDs** such as ibuprofen or naproxen — may increase the risk of kidney problems and reduce diuretic effects. * **Lithium** — spironolactone may increase lithium toxicity risk. * **Digoxin** — spironolactone can affect digoxin levels and interpretation of some laboratory tests. * **Trimethoprim-containing medicines**, particularly trimethoprim-sulfamethoxazole — may substantially increase the risk of hyperkalemia. * Certain medicines that affect kidney function or potassium balance may also require caution. 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 recommended conditions, generally at **room temperature**. * Keep tablets in their original packaging. * Protect from excessive heat, moisture, and direct sunlight. * Keep the medicine tightly closed when not in use. * Keep out of reach and sight of children. * Do not use after the expiry date. * Dispose of unused medicine according to local pharmacy or healthcare guidance. ## Prescription Status **Spironolactone 12.5 mg is generally a prescription medicine.** It should be used under medical supervision, particularly because treatment may require monitoring of **potassium levels, kidney function, and blood pressure**. ## Genuine Medicine Assurance When purchasing Spironolactone 12.5 mg, obtain it from a **licensed pharmacy or authorized medicine supplier**. Before using the medicine, check: * Manufacturer name * Active ingredient and strength * Batch/lot number * Manufacturing and expiry dates * Packaging and seal integrity * Product registration or authorization information where applicable Avoid medicines from unknown or unverified sources, particularly products with damaged packaging or missing batch information. # Frequently Asked Questions (FAQs) ### 1.

Is Spironolactone a diuretic? Yes. Spironolactone is a **potassium-sparing diuretic**. Unlike many other diuretics, it helps the body retain potassium while promoting sodium and water excretion. ### 3. How does Spironolactone 12.5 mg work? It blocks **aldosterone receptors**, causing increased sodium and water excretion while reducing potassium loss. ### 4. Why is Spironolactone called a potassium-sparing diuretic? It promotes fluid removal without causing the same degree of potassium loss as many other diuretics. However, this means potassium can sometimes become **too high**. ### 5. Can Spironolactone 12.5 mg lower blood pressure? Yes. Spironolactone can lower blood pressure and is sometimes used as an additional treatment for hypertension. ### 6. Is Spironolactone 12.5 mg used for heart failure? Yes.
