Tetracycline is used to treat various bacterial infections including dental infections, acne vulgaris, respiratory tract infections, urinary tract infections, chlamydia, and sexually transmitted infections. It is particularly effective for conditions caused by gram-positive and gram-negative bacteria, as well as certain atypical pathogens.
Tetracycline works by binding to the 30S ribosomal subunit in bacterial cells, which inhibits protein synthesis. This prevents bacteria from multiplying and spreading, allowing the body's immune system to eliminate the infection.
Tetracycline should not be taken with dairy products, antacids, or iron supplements as they reduce absorption. It is contraindicated during pregnancy and in children under 8 years old due to effects on bone and teeth development. Common side effects include photosensitivity, gastrointestinal upset, and possible yeast infections. Complete the full course of treatment as prescribed.
