It happened to me several times, bites from my cats or feral cats. My hand got swollen, tight, very warm and reddish, not to mention the pain that at times could be unbearable.
I never used any medication on me because my very personal opinion is that my body has to fight on its own. Generally after 5-7 days everything is alright.
So depending on how he feels and what he thinks about it, he can have some antibiotic or just nothing.
Whatever he chooses to do, best of luck!
