Doxycycline is typically prescribed at 100 mg twice daily for adults for pharyngitis caused by susceptible bacteria. Children’s dosages vary significantly depending on weight and age; always follow your doctor’s instructions precisely. Treatment duration usually lasts 7-10 days. Failure to complete the full course may lead to treatment failure and potential antibiotic resistance.
Side Effects
Common side effects include nausea, vomiting, diarrhea, and abdominal discomfort. Less frequent, but more serious, side effects can involve esophageal irritation (avoid taking the medication before bed), increased sun sensitivity (use sunscreen), and yeast infections (especially in women). Allergic reactions, though rare, can be severe and require immediate medical attention. Report any unusual symptoms to your doctor immediately.
Precautions
Doxycycline should be avoided during pregnancy and breastfeeding. It can negatively impact bone growth in children. Individuals with a history of liver or kidney disease need to discuss its use with their doctor. Concurrent use with certain medications, such as antacids or dairy products, can reduce its effectiveness. Avoid taking doxycycline with alcohol. Finally, always inform your doctor about all medications you currently take, including over-the-counter drugs and supplements, to prevent harmful interactions.
Drug Interactions
Important Note: Doxycycline interacts with several medications, such as warfarin (a blood thinner), antacids containing calcium, magnesium, or aluminum, and certain antibiotics. This list is not exhaustive; consult your doctor or pharmacist for a complete list. Taking doxycycline with these medications may reduce its absorption or cause other harmful interactions.
