Didronel

Generic name: Etidronate
Drug class: Bisphosphonates

Usage of Didronel

Didronel is a bisphosphonate medicine that alters bone formation and breakdown in the body. This can slow bone loss and may help prevent bone fractures.

Didronel is used to treat Paget's disease of bone.

Didronel is also used to treat conditions of irregular bone growth due to total hip replacement or spinal cord injury.

Stop using this medicine and call your doctor at once if you have:

severe pain in your joints, bones, or muscles;

jaw pain, numbness, or swelling;

low calcium levels - muscle spasms or contractions, numbness or tingly feeling (around your mouth, or in your fingers and toes).

Common Didronel side effects may include:

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Before taking Didronel

You should not take Didronel if you are allergic to etidronate, or if you have a condition called osteomalacia (softening of the bones).

To make sure this medicine is safe for you, tell your doctor if you have:

kidney disease;

low levels of calcium in your blood;

a dental problem (you may need a dental exam before you begin taking Didronel); or

if you have had a recent bone fracture.

In rare cases, this medicine may cause bone loss (osteonecrosis) in the jaw. Symptoms include jaw pain or numbness, red or swollen gums, loose teeth, or slow healing after dental work. The longer you use Didronel, the more likely you are to develop this condition.

Osteonecrosis of the jaw may be more likely if you have cancer or received chemotherapy, radiation, or steroids. Other risk factors include blood clotting disorders, anemia (low red blood cells), and a pre existing dental problem.
