  • Aldactone
  • What is Aldactone

    Aldactone (spironolactone) is a prescription diuretic used to remove the excess fluid caused by congestive heart failure, cirrhosis of the liver, and kidney disease. It also can be used in combination with other drugs to treat elevated blood pressure, and for treating diuretic-induced low potassium.

  • How does aldactone work

    Aldactone works by blocking the actions of a hormone in the body called aldosterone. Aldosterone is a hormone that causes the body to retain water. By blocking it, Aldactone increases the amount of salt and water the kidneys remove from the blood. This extra salt and water is passed out through urine. By increasing the amount of water removed from the blood, Aldactone causes a decrease in blood volume. Because of this effect, the medication can lower blood pressure and also help with water retention.

  • Aldactone dosage

    For fluid retention in conditions such as congestive heart failure, cirrhosis of the liver, or kidney disorders, the usual starting dosage is 100 mg daily either in a single dose or divided into smaller doses. In some cases, your doctor may have you take a daily dose as low as 25 mg or as high as 200 mg.

    When potassium loss can't be treated with a potassium supplement, your doctor may have you start with a daily dosage between 25 and 100 mg of Aldactone.

    For essential hypertension the usual starting dosage is 50 to 100 mg daily in a single dose or divided into smaller doses.

  • How does diamox work

    An increase in pressure within your eye can lead to damage to the optic nerve at the back of your eye. When this occurs it is called glaucoma. Glaucoma can lead to a loss of vision if it is not treated. Treatment with Diamox helps to reduce eye pressure, and this helps to prevent further eye damage. Diamox works by blocking the action of an enzyme called carbonic anhydrase. Blocking this enzyme reduces the amount of fluid (called aqueous humour) that you make in the front part of your eye, and this helps to lower the pressure within your eye.

    Glaucoma: the recommended dose range for Diamox is 250 mg-1000mg/day.

My review is solely on the side effects I've been experiencing since I began taking Aldactone, 1 week ago. I was prescribed 50 mg, once a day, Spiro for adult acne by my derm. I cannot vouch to whether or not it is helping my acne. As of yet I don't see improvement, however I understand that part takes time. The side effects currently have me at the edge of withdrawing taking this medicine entirely. My side effects have been foggy brained, shakiness, fatigued, spaced out, restlessness, lots of thirst, frequent urinating, unusual heart beat and headaches. I have noticed that if I drink coffee these symptoms are WORSE. Hoping to have some of these side effects lessen or I will have to throw in my towel on Aldactone.


The increase in hair shedding is a normal, Temporary, side effect of Aldactone (spironolactone). As your hormones adjust the shedding will stop. I have been taking aldactone at 25mg daily for about 1 year, and my skin is now completely oil free, and I have noticed a dramatic decrease in the amount of break outs that I get.


I have been recently diagnosed with the disease called BIH which occurs mostly in women and very young children and currently taking Diamox with annoying side effects such as pins and needles in feet, hands and lips which can last up to 2 hours at a time and be painful. I wake every night with interrupted sleep with a headache or temperature! I have been turned off a lot of food but mainly fizzy drinks.

The dose of acetazolamide for prophylaxis is 125-250 mg twice a day starting 24 hours before ascent, and discontinuing after the second or third night at the maximum altitude (or with descent if that occurs earlier). Sustained release acetazolamide, 500 mg, is also available and may be taken once per day instead of the shorter acting form, though side effects will be more prominent with this dose.
