Zolendronate (Aclasta)

Aclasta (Reclast; Zoledronate) is a bisphosphonate medicine used to treat and prevent thinning of the bones (osteoporosis) and to treat a condition called Paget’s disease.

Taking Aclasta

Aclasta is given once a year by an intravenous (IV) infusion. Infusions take about 15 minutes and must be done at a specialized clinic by a nurse or doctor.
