I was just prescribed Cipro for a high PSA..hoping its just a prostate infection. 500mg for the next 60 days. I am also taking a 7 day Caribbean cruise. Sun and Fun a much needed vacation, I am a sun worshiper and a light drinker... however I do let myself go when on vacation. I know i will have to minimize sun exposure but I not sure how the alcohol will effect me with the drug? Any advice? I know eliminating cancer as a possible cause of high PSA is the goal here and what id important.
