About Etidronate & Calcium

This belongs to the group of medicines known as bisphosphonates.

It is a combination treatment containing two types of tablets, etidronate disodium and calcium carbonate.

This product is used to treat and prevent osteoporosis.

Osteoporosis is a bone disease which causes bones to become brittle and fragile, which can lead to fracture and breakage. During a lifetime, old bone is constantly replaced by new bone. After the age of about 30-35 years, bones begin to lose density because old bone is being lost faster than new bone can replace it.

Each plain white tablet contains etidronate disodium, which belongs to the group of medicines known as bisphosphonates. Bisphosphonates slow down the rate at which old, worn out bone is lost. New bone continues to be deposited which leads to an increase in bone mass.

Each pink-speckled tablet contains calcium carbonate. Calcium is needed to keep bones strong and healthy.

It is also sometimes known as: Didronel PMO. You may notice the use of any of these names on the packaging of your medicine.
