Doxycycline is a prescription-only medicine available as capsules, tablets and syrup.


Doxycycline is a prescription-only antibiotic that belongs to the class of drugs known as tetracycline antibiotics. Doxycycline kills or inhibits the growth of many infection-causing microorganisms. Thus, Doxycycline is widely prescribed to treat various infections and diseases like pneumonia, skin and eye infection, infection of the intestine, genital, and urinary systems.  Doxycycline is clinically proven to be an effective prophylaxis treatment for Malaria. Adults and children above 12 years of age can safely use Doxycycline for the prevention of Malaria.
