Product Overview

Aldactone-A Tablets 50mg is the higher-strength version of Japan’s renowned spironolactone diuretic, offering the same trusted quality and therapeutic effects as the 25mg formulation but with 50 milligrams of active ingredient per tablet. This potassium-sparing diuretic helps your body eliminate excess water and salt while retaining potassium, which aids in lowering high blood pressure and reducing swelling (edema) due to conditions like congestive heart failure, liver cirrhosis, or kidney disease.

Aldactone-A 50mg is often used when moderate to higher doses of spironolactone are required for managing hypertension or edema, and its higher per-tablet dose means you can achieve the needed dosage with fewer pills. It is also utilized in treating specific hormonal issues: doctors may prescribe spironolactone for hormonal acne, polycystic ovary syndrome (PCOS), and other androgen-related conditions because of its hormone-regulating properties. Each Aldactone-A 50mg tablet is made in Japan to the highest pharmaceutical standards, ensuring you receive a safe, effective, and authentic medication with every dose.

Dosage Guidelines

Always take Aldactone-A 50mg exactly as prescribed by your physician. In general, the typical adult dosage ranges from 50 mg to 100 mg per day, which equates to 1–2 tablets of the 50mg strength daily. Depending on your condition, your doctor may have you take the full dose once a day or split it into two doses (morning and afternoon). If a lower dose adjustment is needed, note that Aldactone-A 50mg tablets are scored and can be split into two 25mg halves—only do this if directed by your doctor. Avoid taking your dose late in the evening, since this medication increases urination and could disturb your sleep at night. It’s best to take it in the morning (and if divided, by late afternoon for the second dose). Swallow the tablet with water; you may take it with food to reduce any stomach upset. Do not change your dosing schedule or discontinue use without consulting your healthcare provider. If you have any questions about how to take this medicine, please check with your doctor or pharmacist. For information on what to do if you miss a dose, see the FAQ section below.

Possible Side Effects

As with the 25mg strength, Aldactone-A 50mg can cause side effects in some individuals. The types of side effects are the same as those for spironolactone in general, though higher doses might increase the likelihood or intensity of certain effects. Common side effects include dizziness or light-headedness (especially upon standing) due to lowered blood pressure, increased frequency of urination, mild nausea or stomach upset, and occasional headaches. Because spironolactone influences hormone levels, there can be hormonal side effects: men might experience gynecomastia (swollen or tender breast tissue) or reduced libido, and women might experience breast tenderness, changes in body hair growth, or menstrual irregularities (such as missed periods). These effects are usually dose-dependent and reversible. Also, since this medication is potassium-sparing, it can lead to elevated potassium levels (hyperkalemia) in some cases. Symptoms of high potassium include muscle weakness, numbness or tingling, or an irregular heartbeat. It’s important to have periodic blood tests to monitor your potassium and kidney function, especially when taking higher doses. If you notice signs of hyperkalemia or any severe side effects, contact your doctor promptly.

Serious adverse reactions are rare but can occur. Stop taking Aldactone-A and seek medical care immediately if you experience symptoms of an allergic reaction (such as rash, itching, swelling of the face/lips, or difficulty breathing), severe skin reactions (like widespread rash with blisters), or a significant decrease in urination. Most side effects subside once the dose is adjusted or the medication is stopped under medical advice. Always report any unexpected reactions to your healthcare provider for guidance.

FAQ

Q: What should I do if I miss a dose?
A: If you forget to take a dose, take it as soon as you remember that day. If it’s nearly time for your next scheduled dose, skip the missed dose and continue with your regular schedule. Do not double up on doses to compensate for a missed one. Staying consistent with your dosing is important, so if you have trouble remembering, consider setting an alarm or reminder.

Q: What is the difference between Aldactone-A 25mg and 50mg?
A: Aldactone-A 50mg and 25mg are the same medication in different strengths. The 50mg tablet contains twice as much spironolactone as the 25mg tablet. They are medically equivalent in terms of what they do; the choice of strength depends on the dosage you need as directed by your doctor. Some treatments start with 25mg to allow gradual dose adjustments, while 50mg is used when a higher dose is required, reducing the number of tablets you need to take. Both strengths are manufactured by Pfizer in Japan to the same high-quality standards and have identical effects, with the only difference being the amount of active ingredient per pill. Always follow your physician’s guidance on which strength to use. We carry both options to meet different dosing needs.
