This is terrible advice. Yes, antibiotics will clear up your rash, etc, but telling people to get a supply of antibiotics and just take them whenever is irresponsible.
The over-prescription of antibiotics is already a huge issue, we don't need people taking them when they don't need to (like if you get bit but have no rash or symptoms).
The overuse of antibiotics just leads to more antibiotic resistant diseases.

Agree.
DO NOT LISTEN TO PEARLYBAKERBEST. He is NOT a doctor, and he does not know what he is talking about.
