Important Safety Information:

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. Tell all your health care providers, including your dentist, about all the medicines that you take. Contact your doctor for medical advice about side effects, or if you have questions about ACTONEL.
