Drug Class and Mechanism
Tetracycline is a tetracycline antibiotic. It works by slowing the growth of sensitive bacteria by interfering with the production of proteins needed by the bacteria to grow. Slowing the bacteria's growth allows the body's defense mechanisms to destroy them.
If you miss a dose of Tetracycline and are using it regularly, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Store Tetracycline between 68 and 77 degrees F (20 and 25 degrees C). Brief storage at temperatures between 59 and 86 degrees F (15 and 30 degrees C) is permitted. Store away from heat, moisture, and light. Do not store in the bathroom. Keep Tetracycline out of the reach of children and away from pets.
