Aldactone (Spironolactone)

Spironolactone has caused tumors in laboratory animals. Talk to your doctor about the risks and benefits of using this medication for your condition.

Spironolactone is used to treat certain patients with hyperaldosteronism (the body produces too much aldosterone, a naturally occurring hormone); low potassium levels; heart failure; and in patients with edema (fluid retention) caused by various conditions, including liver, or kidney disease. It is also used alone or with other medications to treat high blood pressure. Spironolactone is in a class of medications called aldosterone receptor antagonists. It causes the kidneys to eliminate unneeded water and sodium from the body into the urine but reduces the loss of potassium from the body. High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.

Spironolactone comes as a tablet and suspension (liquid; Carospir) to take by mouth. It usually is taken once or twice a day. Take spironolactone suspension consistently either with food or without food each time. Take spironolactone at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take spironolactone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Shake the oral suspension well before each use to mix the medication evenly. Your doctor may start you on a low dose of spironolactone and gradually increase your dose. Spironolactone tablets and suspension release the medication differently in your body and cannot be substituted for one another. Only take the spironolactone product prescribed by your doctor and do not switch to a different spironolactone product unless your doctor says that you should. Spironolactone controls high blood pressure, edema, heart failure, and hyperaldosteronism but does not cure these conditions. It may take about 2 weeks or longer before the full effect of spironolactone occurs. Continue to take spironolactone even if you feel well. Do not stop taking spironolactone without talking to your doctor.

Keep this medicine in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.

Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your body's response to spironolactone. Before having any laboratory test, tell your doctor and the laboratory personnel that you are taking spironolactone. Do not let anyone else take your medicine. Ask your pharmacist any questions you have about refilling your prescription. It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
