1. WHAT PAMIDRONATE IS AND WHAT IT IS USED FOR
The name of your medicine is Pamidronate Disodium 3 mg/ ml, 6 mg/ ml or 9 mg/ ml Concentrate For Solution For Infusion which is to be given as a slow injection via a drip. Throughout the rest of the leaflet it will be referred to as Pamidronate.
The active ingredient in Pamidronate is called pamidronate disodium. This is one of a group of medicines called biphosphonates which can help to regulate the amount of calcium in the blood.
High blood calcium levels (hypercalcaemia) occur in a number of conditions, including some types of cancer. Often, hypercalcaemia is caused by the release of calcium from bones. Pamidronate sticks to bones and helps to reduce the release of calcium into the blood. If untreated, hypercalcaemia can cause symptoms such as nausea, tiredness and confusion.
Pamidronate is used to treat high blood calcium levels caused by some cancers. In some patients with cancer, it is also used to treat bone disease and to help relieve bone pain.
Pamidronate is also used to treat Paget’s disease.
