What is a tetracycline and how is it used?
assistant
Tetracyclines are broad-spectrum antibiotics that are used to treat bacterial infections. They work by inhibiting protein synthesis in bacteria, which eventually kills them. Tetracyclines can be taken orally or by injection. Common side effects of tetracyclines include nausea, vomiting, diarrhea, stomach pain, and headache. Long-term use of tetracyclines may cause tooth discoloration and other problems with bone health.
