Minocycline is an antibiotic medication that works by halting the spread and growth of bacteria that cause acne, according to MedlinePlus. This drug is classified as a tetracycline antibiotic, and it is commonly sold under the brand names Dynacin, Minocin and Myrac.
Minocycline is a long-acting antibiotic that is synthesized from natural tetracycline. It is frequently utilized to treat acne vulgaris, and it is similar in efficacy to the antibiotic doxycycline. It is bacteriostatic, meaning that it stops the reproduction of bacteria rather than killing them, but according to Wikipedia, antibiotic-resistant strains of acne-causing bacteria are popping up in the United States and other parts of the world. For this reason, many acne patients are no longer able to rid themselves of acne using tetracycline antibiotics.
Minocycline can be taken orally, and it comes in pellet-filled capsules, tablets and regular capsules. It is most often prescribed for twice-daily consumption, but it may be taken up to four times per day. According to MedlinePlus, this drug should be taken one to two hours between meals on an empty stomach with a full glass of water. Side effects may include diarrhea, dizziness, vaginal or rectal itching, discoloration of the tongue, change in skin color and ringing in the ears.
