I have been taking the big three for about 6 months with very few side effects until two weeks ago. About 5 hours after taking my meds, my mouth broke out in what looked like blood blisters and over the next day or so I noticed unusual bruising on my arms and legs. I called my doctor, but this was not a side effect he had seen before. He ordered blood work which showed an extremely low platelet count. He took me off of Rifampin and within a week everything was back to normal. He would like for me to try it again in 2 or 3 weeks and if I have another bad reaction to it he will look at alternatives. Has anyone else experienced this and if so, what worked for you as a replacement for Rifampin? Needless to say, I am disappointed after having done so well for 6 months. Thanks for any input!
