My mom has Osteoporosis and I would like to know what is the best medicines for her to take??

Hi mimo:  Welcome to the community and thanks for your question.  Your mom's Dr. would have to decide which is the best medication since he or she and your mom, are the only people who know her medical history.  Each of these meds have contraindications (not recommended for some) so it would be very hard to determine which is the best without knowing a patients history.

Here's a link from HealthCentral that lists most of the medications that are used with a detailed description on each.  This link doesn't mention Reclast, so here's a link for that which is a once yearly infused medication.

Good luck trying to decide which medication is the best for your mom.  If you mom is able, it's important for her to have an active role in deciding which treatment she uses.

If you have any other concerns, don't hesitate to post again.
