Dynacin is a prescription drug approved by the U.S. Food and Drug Administration (FDA) to treat infections. Dynacin is sometimes prescribed off-label to treat rheumatoid arthritis. Dynacin is also referred to by its drug name, minocycline. Minocycline is also sold under the brand name Minocin.
Dynacin is an antibiotic of the tetracycline class. Dynacin is also considered a disease-modifying anti-rheumatic drug (DMARD). The exact mechanism of Dynacin in treating rheumatoid arthritis is unknown. It is believed to work by lowering levels of certain proteins that promote inflammation that causes tissue damage.
