85 year old MIL prescribed. My hubby just called concerned that his mother started a prescription for Fosamax (aledronate) two weeks ago. Since then her right leg has started hurting and he saw her stumble. He recalled that my own mom had a very bad reaction to Fosamax, was hospitalized and was taken off it after only two weeks. I see no reason to put these senior seniors on this medication at this stage of life. I will go to her next appointment.
