What are tetracyclines?

Tetracyclines are a group of antibiotics that are effective against a wide range of bacteria. They are commonly used to treat infections such as acne, urinary tract infections, respiratory infections, and certain sexually transmitted diseases.

How do tetracyclines work?

Tetracyclines work by inhibiting the protein synthesis in bacteria. They do this by binding to the bacterial ribosome, which is the cellular machinery responsible for producing proteins. By interfering with protein synthesis, tetracyclines effectively stop the growth and spread of the bacteria in the body.

Common tetracyclines

Some common tetracyclines include:

Tetracycline
Doxycycline
Minocycline

How are tetracyclines used?

Tetracyclines are typically taken orally, either with or without food, as directed by a healthcare professional. They should be taken with a full glass of water to prevent irritation of the esophagus. It is important to finish the entire course of antibiotics, even if the symptoms improve before the medication is gone.

Possible side effects

Like all medications, tetracyclines can have potential side effects. Some common side effects include:

Nausea and vomiting
Diarrhea
Photosensitivity (sensitivity to sunlight)
Tooth discoloration (in children and developing fetuses when taken by pregnant women)
