I was on Fosamax and then Actonel (both alendronic acid) for years, started taking them daily, then weekly, then once a month. It was a pita waiting for the thirty minutes of no eating / drinking after taking them.
I mentioned this to my GP, and he said I can get a six monthly injection called Prolia (denosumab)) if I wanted to change over to it. I have been on it for a year now, and I can have a heartstarter coffee as soon as I get out of bed in the morning.
