Summary
Doxycycline is used to treat bacterial infections, which include respiratory tract infections, skin infections, and sexually transmitted infections. It also helps prevent malaria and treat acne, which is a skin condition causing pimples.
Doxycycline works by stopping bacteria from growing, which helps your body fight infections. It blocks the production of proteins that bacteria need to multiply, which is like stopping a factory from making products by cutting off its supply of raw materials.
For adults, the usual starting dose of doxycycline is 100 mg taken once or twice daily, depending on the condition. For children over 8 years old, the dose is based on body weight. It's taken by mouth with a full glass of water, usually on an empty stomach.
Common side effects of doxycycline include nausea, diarrhea, and increased sensitivity to sunlight, which means you can get sunburned more easily. These effects are usually mild and may go away on their own.
Doxycycline should not be used if you're allergic to it or other tetracycline antibiotics. It's not recommended for children under 8 years old or pregnant and breastfeeding women due to risks to teeth and bone development. Avoid excessive sun exposure and use sunscreen.
