I was prescribed Doxycycline for malaria prevention in Tanzania.. After two days I had severe chest pain when breathing (especially deeply) and swallowing water- the full glass with the tablet was hell & then food. I lost my appetite completely, felt nauseous when I forced myself to eat meals and thought I was about to have a heart attack. I've been off the drug for 4 days and have stomach pain, nausea, no appetite, very dry sore skin and insomnia (which is more likely due to jetlag)! My parents both developed a hive-like sore rash all over their bodies after the first day of taking the doxycycline. It is shocking that these 'severe side effects' are so common, especially when finding an ER in central Serengeti is difficult..
