Doxycycline hyclate (
Vibramycin, 
Acticlate, Morgidox) is a moderately priced drug used to treat many kinds of infections, like dental, skin, respiratory, and 
urinary tract infections. It also treats 
acne, 
Lyme disease, 
malaria, and certain sexually transmitted diseases. This drug is more popular than comparable drugs. It is available in multiple generic and brand versions. Generic 
doxycycline hyclate is covered by most Medicare and insurance plans, but manufacturer and pharmacy coupons can offset the cost.
