This drug contains the active ingredient tetracycline hydrochloride, which belongs to a group of antibiotics called the
tetracyclines. Tetracycline is prescribed to treat infections caindicated by bacteria.
Tetracycline works by interfering with the ability of bacteria to produce proteins that are essential to them. Without
these proteins the bacteria cannot grow, multiply and increase in numbers. Tetracycline therefore stops the spread of the
infection and the remaining bacteria are killed by the immune system or eventually die.
Tetracycline is a broad spectrum antibiotic that is active against a wide variety of bacteria. However, some strains of
bacteria have developed resistance to this antibiotic, which has reduced its effectiveness for treating some types of
Tetracycline is still prescribed to treat infections caindicated by chlamydia (eg the chest infection psittacosis,

Tetracycline is prescribed to treat acne, due to its activity against the bacteria on the skin that cause
acne (Propionebacterium acnes). Tetracycline is prescribed to treat flare-ups of chronic bronchitis, due to its
activity against the bacteria usually responsible, Haemophilus influenzae.
Tetracycline is also prescribed to treat other rarer infections, such as those caindicated by a group of micro-organisms
called rickettsiae (eg Q fever, Rocky mountain spotted fever) and those caindicated by Brucella bacteria (brucellosis).
To make sure the bacteria causing an infection are susceptible to tetracycline your doctor may take a tissue sample, for
example a swab from the infected area, or a urine or blood sample.
This belongs to the group of drugs known as antibiotics.
Tetracycline is prescribed to treat various types of bacterial infections by killing or stopping the growth of the
bacteria. Tetracycline is particularly useful for treating skin conditions, such as acne.
