Different drugs have different strengths. Some drugs are more powerful and thus lower mg amounts can be used. Both Fosamax and Boniva are similarly effective for osteoporosis.
Boniva vs. Fosamax, comparable doses?
If once a month Boniva is 150 mg how can it be comparable to Fosamax, which is approximately 70mg a week,I believe.70 mg times 4 or 5 weeks = 280/350 mg?
