Indications

Risonet belongs to a group of medicines called bisphosphonates. It works by altering the natural cycle of bone formation and breakdown in the body, slowing bone loss while increasing bone mass, which may help prevent fractures. It is a prescription medicine used to prevent and treat osteoporosis in postmenopausal women, to increase bone mass in men with osteoporosis, to prevent and treat osteoporosis caused by long-term treatment with steroid medicines such as prednisone in both men and women, and to treat Paget's disease of bone in men and women.

⚠️ Always consult a registered physician before taking any medicine.

Pharmacology

Bones are living tissue that your body constantly breaks down and rebuilds. If you have osteoporosis, bone is broken down faster than it is replaced, so bone loss occurs gradually and your bones become thinner and more fragile. This is especially common in women after menopause (change of life). Many people with osteoporosis have no symptoms and may not even know they have it. However, osteoporosis makes fractures (broken bones) more likely, particularly in the spine, hips and wrists.

Risedronate binds to hydroxyapatite crystals in bone and works as an antiresorptive agent. At the cellular level, it inhibits osteoclasts. These osteoclasts continue to attach normally to the bone surface, but show reduced active resorption.

Pregnancy & Breastfeeding

Risedronate Sodium is intended only for postmenopausal women, so it should not be used during pregnancy. If you happen to take it while pregnant, stop right away and let your doctor know. The same applies during breastfeeding: since this medicine is meant only for postmenopausal women, breastfeeding mothers should not take it. Should it be taken by accident while breastfeeding, stop immediately and consult your doctor.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.
