Dog bite and its treatment does not require any form of dietary restriction. But personally avoid alcohol and beverages containing alcohol while on any medication as it may interact with drugs as alcohol is also a drug.
When ever bitten by any animal which has propensity to transmit rabies
like Dog etc, do clean the wound with plenty of water and clean with soap and later apply betadine
and leave the wound open. Rabies requires anti rabies injections as per WHO schedule, vaccinated at Day0.3.14.21.28 and booster if required at 6 months along with shot of Inj Tetanus toxoid
.Do take care...wish you a speedy recovery!
