Doxycycline is a common antibiotic often used for the treatment of various infections, such as bacterial infections, anthrax, malaria, and acne. The medication is part of a class of drugs called tetracyclines, and works by decreasing bacteria's ability to make protein (which bacteria need in order to live). Doxycycline is available in capsule, tablet, or injection form. It is usually taken once or twice a day.

 

You should take your doxycycline dose at the same time each day to maintain an even level of the medicine in your system. Seek medical attention immediately if you happen to overdose on doxycycline. Symptoms of a doxycycline overdose can include nausea, diarrhea, and loss of appetite. You should talk with your healthcare provider before taking doxycycline if you are pregnant or breastfeeding. You should also let your healthcare provider know (prior to taking doxycycline) if you have liver disease or failure, as well as any allergies.
