Tetracycline is an antibiotic used to treat various bacterial infections. It is effective against acne, urinary tract infections, respiratory infections, skin infections, Lyme disease, and some sexually transmitted infections like chlamydia. It can also treat stomach ulcers caused by H. pylori bacteria.
Tetracycline works by stopping bacteria from making proteins, which they need to grow and multiply. This slows down the infection and allows the immune system to kill the bacteria.
For adults, the usual dose of Tetracycline is 250 mg to 500 mg every 6 hours. For children above 8 years, the dose is based on body weight, usually 25-50 mg per kg daily divided into smaller doses. It should be taken on an empty stomach, either one hour before or two hours after meals, with a full glass of water.
Common side effects of Tetracycline include nausea, vomiting, diarrhea, stomach pain, and skin sensitivity to sunlight. Rare but serious side effects include severe allergic reactions, liver damage, or teeth discoloration in children.
Tetracycline should not be used by children under 8 years, pregnant or breastfeeding women, and people with liver or kidney disease. It can cause permanent tooth discoloration in young children and harm a baby's teeth and bones if used during pregnancy. Always inform your doctor about other medicines you take as Tetracycline can interact with certain medications.
