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?


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.
