Calcium Acetate

Calcium acetate is used to control high blood levels of phosphorus in people with kidney disease who are on dialysis (medical treatment to clean the blood when the kidneys are not working properly). Calcium acetate is in a class of medications called phosphate binders. It binds phosphorus that you get from foods in your diet and prevents it from being absorbed into your blood stream.

🔔 How should this medicine be used?

Calcium acetate comes as a capsule, tablet, and a solution (liquid) to take by mouth. It is usually taken along with each meal (e.g., 3 times a day if you eat 3 meals a day) as directed by your doctor. Take calcium acetate at around the same times 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 calcium acetate exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

If you are using the solution, do not use a household spoon to measure your dose. Use the dosing cup that comes with the medication to measure your dose. Ask your pharmacist if you have any question about how much medication you should take or how to use the dosing cup.

Your doctor will probably adjust your dose based on your phosphorus blood levels, not more often than once every 2 to 3 weeks.

Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient.

🔔 What special precautions should I follow?

Before taking calcium acetate,

• tell your doctor and pharmacist if you are allergic to calcium acetate, any other medications, or any of the ingredients in calcium acetate preparations. Ask your pharmacist for a list of the ingredients.
• tell your doctor and pharmacist what other prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: digoxin (Lanoxin). Take a fluoroquinolone antibiotic such as ciprofloxacin (Cipro), gemifloxacin (Factive), levofloxacin, or moxifloxacin (Avelox) at least 2 hours before or 6 hours after taking calcium acetate. Also, take levothyroxine (Euthyrox, Synthroid, Tirosint) at least 4 hours before or 4 hours after taking calcium acetate. Take a tetracycline antibiotic such as demeclocycline, doxycycline (Monodox, Oracea, Vibramcyin), minocycline (Dynacin, Minocin, Solodyn), or tetracycline (Achromycin V, in Pylera) at least 1 hour before taking calcium acetate. Your doctor may need to change the doses of your medications or monitor you carefully for side effects. Many other medications may also interact with calcium acetate, so be sure to tell your doctor about all the medications you are taking, even those that do not appear on this list.
• tell your doctor if you are taking calcium supplements or calcium antacids (Tums). Do not take supplements or antacids containing calcium while taking calcium acetate.
• tell your doctor if you have high levels of calcium in the blood. Your doctor will probably tell you not to take calcium acetate.
• tell your doctor if you have or have ever had any other medical conditions.
• tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking calcium acetate, call your doctor.

🔔 What should I know about storage and disposal of this medication?

Keep this medication 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.

🔔 What other information should I know?
