Ajay asked...

I was diagnosed with Osteoporosis some 18 months ago. I was consulting a Rheumatologist privately and he prescribed me once a week Fosamax tablet 70mg. That is what my GP gave me as well.

Now past one year I have to change my GP because we moved house. My current GP gives me Alderonic acid 70mg. My question is, is there is any difference between the two?

The Answer

Fosamax is a branded formulation of alendronic acid.  They contain identical strength of alendronic acid in the form of sodium alendronate trihydrate. They both share identical side effect profiles with the most common side effects being musculoskeletal (bone, muscle or joint) pain which is sometimes severe.

I hope this is of some assistance to you.
