Hello all! My 10 year old child is having typhoid. He was having very high fever for the last two days with red rashes on his skin. I took him to the doctor where he was tested as Salmonella typhi positive. Its all due to his unhealthy eating habits at school canteen I am sure but he wont listen. Now, I am interested to know about penicillin as an anti-biotic for him. Tell me its possible side-effects and usage? Thanks!
