Hi Vinton, welcome... Here's a list of the most common side effects for Actonel from HealthSquare.
Abdominal pain, constipation, diarrhea, dizziness, flu symptoms, general aches and pain, headache, high blood pressure, indigestion, infection, joint pain, muscle pain, nausea, nerve pain.
Some people have some of these side effects and some don't, so it's really hard to say which you'll be. This drug stays in the system for some time, so if you have a reaction there is a possibility that it could last more than a few days.
Can you talk to others at your Drs office to see how they are doing? I'm sure you'll find that there are many different reactions, and maybe they could help you.
Good luck deciding on this.
