Hives

Well I just started to take this pill and right when I started to take it I went tanning and then I broke out on my face just on the left side some red dots and they were itchy but they went away and then I broke out in hives after tanning again on my chest. My question I guess is should I call my doctor about this or not I mean it went away right away I have no abdomonal pain or anything else. I dont know if I should keep taking this for the trial 3 months and see how it goes but I do plan on being outside more and I am afraid if I do go out side I will break out. Please help me on what to do......
