Only one study in 2001 tested this hypothesis at one hospital in New York.

For the study, the bullseye rash was the diagnostic criteria to determine if doxy prevented LD. The study actually showed that people bitten by nymphs were more likely to develop a bullseye rash and therefore diagnosed with LD in comparison with those bitten by an adult tick. None of those bitten by adult ticks developed a bullseye rash.

The Bullseye is a poor indicator of LD.

Only 50% with LD got any kind of rash and only 9% developed a bullseye.

Two pills used at the time of tick bite by a nymph prevented people from getting the bullseye – so they were not diagnosed as having LD and were excluded from the study.

So, will 2 pills of doxy prevent Lyme?

No.
