Product Information


Doxycycline hyclate is the active ingredient of Doxycept. It contains 100mg of the broad-spectum antibiotic belonging to the tetracycline family. It is an effective treatment for a wide variety of bacterial infections caused gram-positive and gram-negative bacteria such as chlamydias, mycoplasmas, rickettsiae, staphylococci, bacteroides species, peptococcus species, propionibacterium species, even protozoan parasites and more.


This drug is used in treating infections of the respiratory and urinary tracts, in treating acne vulgaris and acne rosacea, pneumonia and many others. This drug may also be used in the treatment of malaria and prophylaxis for some types of malaria, anthrax and leptospirosis. It is the drug of choice in for Rocky Mountain spotted fever.


Doxycycline binds to the 30S subunit of the bacterial ribosome, preventing addition of amino acids to the growing peptide, thus leading to protein synthesis inhibition. By inhibiting protein synthesis, this slows bacterial growth thus allowing the body’s immune system to fight the bacterial infection.


Doxycept should only be used in the treatment of infections caused by susceptible bacteria. It will not work in treating viral infections. Misuse of antibiotics can cause a decrease in effectiveness.
