How to take doxycycline if bitten by a tick? - in detail
A tick bite can introduce bacteria that cause Lyme disease; prompt antibiotic therapy reduces infection risk. The standard prophylactic regimen involves a single oral dose of doxycycline taken within 72 hours of removal, provided the tick was attached for at least 36 hours, the bite occurred in an area where Lyme disease is endemic, and the patient is an adult or a child weighing at least 15 kg.
The recommended dose is 200 mg (one 100 mg tablet taken twice). Swallow the tablets whole with at least 8 oz of water. Remain upright for 30 minutes to prevent esophageal irritation. Food does not markedly affect absorption, but dairy products, calcium supplements, and antacids should be avoided for two hours before and after dosing because they bind the drug and lower bioavailability.
Contraindications include known hypersensitivity to tetracyclines, pregnancy, breastfeeding, and children under eight years of age. Severe liver impairment also warrants avoidance. If any of these conditions apply, alternative antibiotics such as amoxicillin must be considered.
Common adverse effects are mild gastrointestinal discomfort, nausea, and photosensitivity. To lessen irritation, take the medication with a full glass of water and stay upright. Sun protection (clothing, sunscreen) reduces the risk of skin reactions.
After the dose, observe for signs of infection—expanding erythema, fever, chills, fatigue, or joint pain. If symptoms appear, seek medical evaluation for possible full-course therapy. Documentation of the tick’s identification, attachment time, and geographic location assists clinicians in assessing ongoing risk.
