What is osteoporosis?

Osteoporosis is a disease in which bones become weaker and more likely to break. And what’s worse, you may not even feel it happening.

How do your bones get weaker? Your bones are living tissue. They constantly renew themselves with cells that build bone and cells that take away bone. With osteoporosis, your bones lose density, making them weaker and more likely to fracture.

ACTONEL is for the treatment of postmenopausal osteoporosis.
Your doctor may also prescribe ACTONEL to help prevent postmenopausal osteoporosis.

Important Safety Information for
ACTONEL^® (risedronate sodium) tablets

You should not take Actonel if you are allergic to any of the ingredients, if you have low blood calcium (hypocalcemia), have kidneys that work poorly, or cannot stand or sit upright for 30 minutes.

Stop taking Actonel and tell your doctor right away if you experience difficult or painful swallowing, chest pain, or severe or continuing heartburn, as these may be signs of serious upper digestive problems. Follow dosing instructions carefully to lower the chance of these events occurring.

Side effects may include stomach pain, upset stomach, or back, muscle, bone or joint pain, sometimes severe. Contact your doctor for medical advice about side effects, or if you have questions about Actonel. Promptly tell your doctor if you develop dental problems, as serious jawbone problems have been reported rarely.
