Calcium Acetate is a phosphate binder that works by holding onto phosphate from the diet so that it can pass out of the body. It is primarily indicated for patients with end-stage renal failure to prevent hyperphosphataemia. This active ingredient is found in several trusted generic formulations. Our platform ensures reliable access to high-quality medications containing Calcium Acetate for your ongoing treatment needs.
Calcium acetate belongs to a group of medicines known as phosphate binders. Its main role is to attach to the phosphate that comes from food, turning it into a substance that the body can’t absorb. By doing this, calcium acetate helps keep blood phosphate levels within a normal range. It is the active ingredient in products such as Phoslo and several other formulations available across the UK.
In the United Kingdom, calcium acetate is most commonly found in the brand-name product Phoslo. Phoslo is supplied as oral tablets and is marketed as a phosphate-binding therapy. Generic versions of calcium acetate may also be dispensed by community pharmacies, often in similar tablet strengths. The medication is typically offered in single-ingredient form, though some preparations combine calcium acetate with other binders to provide a broader range of phosphate-binding options. Availability can vary between NHS formularies and private prescriptions, so patients may encounter different pack sizes or brand names depending on their local pharmacy.
Calcium acetate is used to manage conditions where excess phosphate in the blood is a concern. The most common situations include:
By reducing the amount of phosphate that enters the bloodstream, calcium acetate supports overall mineral balance and can help protect bones and blood vessels from the damage that high phosphate levels may cause.
When calcium acetate is taken with meals, it binds to the phosphate present in the food. The resulting complex is too large for the intestinal wall to absorb, so it passes out of the body in the stool. Because the phosphate is not taken up, blood levels stay lower than they would be without the medication. The binding effect begins shortly after the tablet is swallowed and continues while the meal is being digested, providing a relatively quick reduction in phosphate absorption.
These reactions are generally short-lived and do not require medical attention unless they persist.
If any of these occur, seek emergency care without delay.
Calcium acetate can affect the absorption of certain medicines and nutrients:
Avoid drinking large amounts of milk or calcium-rich beverages at the same time as your calcium acetate tablet unless advised otherwise. For a full list of possible interactions, refer to the specific product information for Phoslo or consult the medication’s detailed leaflet.
Store calcium acetate tablets in a dry place away from direct sunlight and at room temperature. Keep them out of reach of children. Most phosphate-binding therapy is intended for short-term use during dialysis cycles, but the exact duration depends on individual health needs and the specific product prescribed. Always follow the instructions printed on your medication pack and remember that other calcium acetate products may have different strengths or dosing schedules. For detailed usage, dosing, and administration guidance, refer to the information supplied with your particular medication.
Hyperphosphataemia: An unusually high level of phosphate in the blood, often seen in kidney disease. Phosphate binder: A medication that attaches to dietary phosphate, preventing its absorption.
