Suggest Treatment For Itchy Bumps On Stomach

I'm taking oxy elite pro for weight loss and on day 2, I pill a day for the first three days then two every day for four weeks. This morning I woke up with about 5 bumps on my stomach, almost looks lime a bug bit, it itches a little. I put some hydrocortizon on it. I really don't want to stop taking the medicine because I think it will help.
