Doxycycline is a broad-spectrum tetracycline antibiotic. As such, it is used in situations when a disease has been identified, but it is impossible to indentify its causative agent, as one and the same disease can be caused by hundreds of different bacteria (e.g., pneumonia). Doxycycline is prescribed for treating bacteria infections, including urinary tract infections, acne, gonorrhea, periodontitis, staphylococcus, rosacea, and others. Doxycycline's ability to suppress chlamydia growth is especially important with the growing number of such patients. It is important not to confuse bacterial infections with viral infections (e.g., flu, cold, etc.), for which Doxycycline will not work.
Doxycycline acts by penetrating into cells and inhibiting protein synthesis, which kills bacteria. Doxycycline comes in a variety of forms: capsules, tablets, suspension, syrup, and powder for injections. Doctor prescribes Doxycycline dosage depending on the particular infection. It is usually well tolerated and has no serious side effects.
