Azithromycin
"After reviewing all these reviews I was mega mega nervous taking this. Caught chlamydia and had to take the single dose of 4 tablets. Was expecting sickness, diarrhoea, vomiting and pretty bad stomach pains. Had some cereal in the morning then 2 hours later took the tablets with some water and waited for the onset of horridness. I'm writing this because reading these reviews can be misleading as people are way more likely to want to vent if they have a bad experience, which is what terrified me. Besides a very small amount of diarrhoea which wasn't uncomfortable whatsoever and a few painless stomach growls, I haven't had any other side-effects whatsoever. Take these reviews with a pinch of salt!"
