Doxycycline
Summary
Doxycycline is an antibiotic used to treat a variety of bacterial infections. It's commonly used for conditions like acne, Lyme disease, and chlamydia. It's also used for inflammatory rosacea, a skin condition causing redness and pimples on the face. Additionally, it's used to prevent malaria in travelers.
Doxycycline works by inhibiting the protein synthesis of bacteria, which prevents them from growing and spreading in the body. This allows your immune system to eliminate the infection more effectively.
Doxycycline is taken orally, usually once a day. It should be taken with plenty of fluids to avoid irritation of the esophagus. The dosage depends on the type of infection being treated, and it's important to take it exactly as prescribed by your doctor.
Common side effects of Doxycycline include nausea, vomiting, diarrhea, and increased sensitivity to sunlight. Rare but serious side effects include liver toxicity, allergic reactions, and irritation of the esophagus.
Doxycycline should not be used by children under 8, pregnant women (unless necessary), and people with severe liver disease. It can cause tooth discoloration in children. It's also important to avoid taking it with dairy products as they can interfere with its absorption. If you experience symptoms like headaches or blurred vision, stop taking the medication and contact your doctor immediately.
