Minocin (Minocycline Hydrochloride)

(mi noe sye' kleen)

Minocycline is used to treat infections caused by bacteria including pneumonia and other respiratory tract infections; certain infections of the skin, eye, lymphatic, intestinal, genital, and urinary systems; and certain other infections that are spread by ticks, lice, mites, and infected animals. It is also used along with other medications to treat acne. Minocycline is also used to treat plague and tuleramia (serious infections that may be spread on purpose as part of a bioterror attack). It can also be used in patients who cannot be treated with penicillin to treat certain types of food poisoning, and anthrax (a serious infection that may be spread on purpose as part of a bioterror attack). It can also be used to eliminate bacteria from your nose and throat that may cause meningitis (swelling of tissues around the brain) in others, even though you may not have an infection. Minocycline extended-release tablet (Solodyn) is only used to treat acne. Minocycline is in a class of medications called tetracycline antibiotics. It works to treat infections by preventing the growth and spread of bacteria. It works to treat acne by killing the bacteria that infects pores and decreasing a certain natural oily substance that causes acne. Antibiotics such as minocycline will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.

Minocycline comes as a regular capsule, a pellet-filled capsule, and an extended-release tablet (Solodyn) to take by mouth. The capsule and pellet-filled capsule is usually taken twice a day (every 12 hours) or four times a day (every 6 hours). The extended-release tablet is usually taken once a day to treat acne. Minocycline can be taken with or without food. Drink a full glass of water with each dose. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take minocycline exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Swallow the pellet-filled capsules and extended-release tablets whole; do not split, chew, or crush them.
