How should remantadine be taken by an adult after a tick bite? - briefly

How should remantadine be taken by an adult after a tick bite? - in detail
When a tick bite raises concern for Lyme disease, an adult may be prescribed a 5‑day course of oral doxycycline (commonly referenced as remantadine) as prophylaxis. The regimen consists of 100 mg taken twice daily, with each dose spaced approximately 12 hours apart. Tablets should be swallowed whole with a full glass of water; taking the medication with food can reduce gastrointestinal discomfort, but high‑calcium foods or antacids should be avoided within two hours of dosing because they impair absorption.
The first dose should be administered as soon as possible after the bite, ideally within 72 hours, and no later than 72 hours from the time of exposure. Completion of the full 5‑day schedule is required; stopping early may compromise efficacy.
Monitoring includes observing for rash, severe nausea, vomiting, or signs of an allergic reaction. If any of these occur, discontinue the medication and seek medical evaluation. Renal or hepatic impairment may necessitate dose adjustment; consult a healthcare professional before initiating therapy in such cases.
Drug interactions to consider: concurrent use of isotretinoin, thiazide diuretics, or anticoagulants may increase the risk of adverse effects. Proton‑pump inhibitors and calcium supplements can lower doxycycline plasma levels and should be timed appropriately.
Pregnant or breastfeeding individuals should avoid this antibiotic; alternative prophylaxis must be discussed with a clinician. Ensure that the patient has no known hypersensitivity to tetracyclines before prescribing.
