Hello,
This is Dr. Klarida Papaqako answering your question.
Puncture cat scratches are wounds very prone to get infected because of the bacteria's that they inoculate to the place of the wound. So in general it's recommend the use of antibiotic to prevent systemic illness.
--If I was your caring doctor, and the scratch was a cat bite I would recommend to take amoxicillin-
clavulanate 875 mg orally every 12 hours for 3-5 days.
--If it was a scratch with the cat nails, I would look at the scratch, keep it as clean as possible, and if it gathers puss on it, or if lymphonodes in the area around the scratch gets bigger, I would go and see a doctor if you have other symptoms as
fever or systemic problems.
In both cases consider taking
Ibuprofen 400mg after food as needed for the pain.
Also, you may need the
Tetanus shot if you have not done it in the next 5 years, and the
Rabies shot if the scratch was with the cat teeth.
Hope the information helps,
Take care.
