Side effects of Allocate/Claritin for treatment of capsular contracture?

This past week I went for a consult with a new surgeon for capsulectomy. He put me on Allocate to see if it was treatable that way and told me to lay on my chest as much as possible or give compression to capsulated breast when possible. Since starting Allocate/Claritin I have had some additional pain/cramping and wonder if this is normal reaction to this medicine. Dr said it would generally take a month to see any result in treatment
