Product Overview

Aldactone-A Tablets 25mg is a Japanese-manufactured spironolactone medication known for its high quality and effectiveness. As a potassium-sparing diuretic, it helps eliminate excess fluids from the body without causing potassium loss, thereby lowering high blood pressure and reducing swelling (edema). This trusted treatment is commonly used for hypertension, edema associated with congestive heart failure, liver cirrhosis, or kidney disorders, and for managing certain hormonal imbalances.

Many doctors also prescribe spironolactone to address issues like hormonal acne or polycystic ovary syndrome (PCOS) due to its hormone-regulating benefits. With Aldactone-A 25mg, you can benefit from Japan’s rigorous pharmaceutical standards, ensuring safety and reliability in every tablet.

Dosage Guidelines

Always follow your physician’s dosage instructions for Aldactone-A 25mg. A typical adult dose ranges from 50 mg to 100 mg per day, which corresponds to 2–4 tablets of 25 mg taken in one or two divided doses. Your doctor may start you on a lower dose (such as 25 mg daily) and adjust gradually based on your response and condition. It's recommended to take this medication in the morning or early afternoon, as taking it late in the evening could cause frequent urination at night and disrupt sleep. Swallow the tablets with water; you may take them with or after a meal if it suits your stomach. Do not change your dosage or stop taking Aldactone-A without consulting your healthcare provider. For guidance on missed doses, see the FAQ section below.

Possible Side Effects

Like all medications, Aldactone-A 25mg may cause side effects in some users. Common side effects include dizziness or lightheadedness (especially when standing up) due to lowered blood pressure, increased urination, mild nausea or stomach upset, and headaches. Because spironolactone affects hormone levels, some people may experience breast tenderness or enlargement (gynecomastia in males), and women might notice changes in their menstrual cycle or breast discomfort. Other possible effects include reduced libido or erectile dysfunction in men, or changes in body hair growth patterns. This medication can also raise potassium levels; while it is designed to spare potassium, in some cases potassium might build up in the body (hyperkalemia). Signs of high potassium can include muscle weakness, tingling sensations, or an irregular heartbeat – if you suspect these, contact your doctor. It’s advisable to have periodic blood tests to monitor electrolytes and kidney function during long-term use.

Serious adverse reactions are rare but possible. Stop taking the medication and seek medical attention immediately if you experience severe symptoms such as an allergic reaction (e.g., rash, itching, swelling of the face or throat, difficulty breathing), severe skin rashes or blistering, or greatly reduced urination. Most side effects are reversible and will resolve after adjusting the dose or discontinuing the drug under medical supervision. Always inform your healthcare provider about any side effects you experience so they can provide proper guidance.

FAQ

Q: What should I do if I miss a dose?
A: If you forget to take a scheduled dose, take it as soon as you remember on the same day. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take two doses at once to make up for a missed dose. Taking your medication consistently at the same time each day is important for it to work properly, so consider setting a reminder if needed.

Q: What is the difference between Aldactone-A 25mg and 50mg?
A: The primary difference is the strength of each tablet – Aldactone-A 25mg contains 25 milligrams of spironolactone per pill, whereas Aldactone-A 50mg contains 50 milligrams. Both are the same medication from the same manufacturer and have identical effects; the choice depends on the dose your doctor has prescribed. The 25mg tablets are often used when a lower dose is needed or for starting therapy, as they allow finer dose adjustments (you can take multiple 25mg tablets to reach a higher dose if necessary). The 50mg tablets are convenient for higher daily dosages because they reduce the number of pills you need to take. Always follow your healthcare provider’s guidance on which strength is right for you. We offer both strengths to accommodate different needs, and both are made to the same high quality standards in Japan.
