yes, but it's most likely because the medicine still needs time to fight the infection. Keep an eye on the fever, if it gets to high take him to the ER. I wouldn't give him any other medicine unless you talk to your doctor because you don't know how they will react to each other an dyou don't want him to have a bad reaction.
Other than that, just keep an eye on the fever, if it continues for more than a day or two, call the dr. back so he can see him again, and maybe get a different medication.
