A single prophylactic 200mg dose of Doxycyline prevents Lyme disease
Had to take doxycycline for 2 weeks after a tick bite. Man does that stuff destroy your digestive system. 7 years ago was on a date, just casually walking down the street. Coughed a couple times for no particular reason but my doxycycline lined stomach didn’t like that and boom projectile vomiting. Luckily he thought it was funny/ felt bad for me.
