Summary
Tetracycline is used to treat bacterial infections, which include respiratory tract infections, acne, and urinary tract infections. It helps clear these infections by stopping the growth of bacteria. Your doctor might also prescribe it for other infections based on your specific health needs.
Tetracycline works by inhibiting bacterial growth, which means it stops bacteria from making proteins they need to grow and multiply. This allows your body's immune system to clear the infection more effectively.
The usual adult dose of tetracycline is 250 mg to 500 mg every 6 hours. For children over 8 years old, the dose is based on body weight. It's taken orally on an empty stomach with a full glass of water, usually two to four times daily.
Common side effects of tetracycline include nausea, vomiting, and diarrhea, which are unwanted reactions to the medication. These effects are usually mild and occur in a small percentage of people taking the drug.
Tetracycline should not be used by pregnant women or children under 8 years old due to risks like permanent tooth discoloration. It can also increase sensitivity to sunlight, so use sunscreen. Avoid if you have severe liver or kidney disease.
