On Monday night of last week I began taking amoxicillin as part of treatment for a tooth implant operation I was having done the next morning (last Tuesday). I took 2 amoxicillin capsules a day, each day until the next week, Tuesday the 13th. Everything was going fine, I felt zero side effects and was exercising and going to school regularly. That Tuesday night I took a capsule before going to bed and noticed red dots popping up on my arms and stomach area. Since then I have discontinued taking the antibiotic.
I have done some research online and am thinking it is either an amoxicillin rash or an allergic reaction to the amoxicillin. The thing that puzzles me is that it took place 8 days after taking the amoxicillin, and not immediately after taking one capsule.
The rash grew a lot over that first night and was not itchy right away, but after a day or two it became mildly itchy. I have been taking benadryl since Wednesday night. It seems now that the color is fading and the dots have merged or grouped together. It seemed to start on my torso and arms and spread as far as my upper legs and neck. I do have a bit of redness on my face, and some dots on my lower legs (calves) but not as much as in the middle portion of my body.
If it was indeed an allergic reaction would I have broke out in rash/hives right after taking a capsule or would it have been delayed like the 8 days in between?
