Doxycycline is a daily antimalarial prophylaxis. In fewer syllables: it helps prevent malaria. It is my third line of defense after killing every mosquito I meet and mosquito nets.
It has a multitude of other uses. For example, my skin will be clear of acne, and there is almost no chance I will be harmed by anthrax nor the bubonic plague. Regardless of its other uses, I use it to prevent malaria, so I’m glad it exists and I am happy take a daily dose.
Worth noting, however, is that it must be taken after eating a reasonable meal. “A good bed of food” was the description given by my local coordinator.
…which I learned after I found out what ‘doxy’ looks like on the inside of a toilet bowl.
