How to take tetracycline after a tick bite? - in detail
After a tick attachment, begin a tetracycline‑type antibiotic promptly if prophylaxis is indicated. The usual agent is doxycycline, administered at a dose of 200 mg once daily for 21 days. Initiate treatment within 72 hours of the bite; delayed start reduces protective effect.
Take the tablet with a full glass of water. Remain upright for at least 30 minutes to lessen esophageal irritation. Do not consume dairy products, antacids, or calcium‑rich supplements within two hours of the dose, as they impair absorption.
If a single‑dose regimen is prescribed (200 mg taken once), ensure the medication is taken on an empty stomach, preferably in the morning. For the extended 21‑day course, maintain consistent timing each day to sustain therapeutic levels.
Monitor for adverse reactions: gastrointestinal upset, photosensitivity, or rash. Report severe nausea, vomiting, or signs of an allergic response immediately. Routine blood tests are not required for short courses, but liver function should be assessed in patients with pre‑existing hepatic disease.
Complete the full prescribed duration, even if symptoms subside early. Discontinue only under medical guidance. If a rash or fever develops after starting therapy, seek evaluation to rule out early Lyme disease or drug reaction.
