Rat Bite Treatment: What to Expect from a Doctor

Rat bites carry infection risk (rat-bite fever, leptospirosis, tetanus, cellulitis). Prompt medical care is essential.

Standard Clinical Steps

1. Assessment: Examine wound depth, location, neurovascular status, signs of infection (redness, swelling, pus, lymphangitis).
2. Irrigation & Cleaning: Copious saline flush; debride devitalized tissue if needed.
3. Wound Management:
   • Superficial: Leave open or approximate with steri-strips.
   • Deep/complex: May require delayed primary closure or loose approximation to allow drainage.
4. Antibiotic Prophylaxis: Typically amoxicillin-clavulanate (Augmentin) 875/125 mg BID × 3–5 days for puncture/deep wounds. Alternatives for penicillin allergy: doxycycline + metronidazole.
5. Tetanus Update: Booster if >5 years since last dose (or >10 years for clean minor wounds). Tetanus immune globulin if immunization incomplete/unknown.
6. Rabies Assessment: Rare from rodents, but evaluate per local epidemiology.
7. Follow-Up: Recheck in 48–72 hrs for infection signs. Complete antibiotic course.

Red Flags Requiring Urgent Care

• Spreading redness, fever, chills
• Joint pain/rash (rat-bite fever: Streptobacillus moniliformis)
• Inability to move digit/limb
• Immunocompromised patient

Report bites to local health department if required by jurisdiction.
