Husband on amox generic for seven days for sinus infection...took last pill 7 days ago. as of last night, has fever 103.3. felt better after starting amox. does he need a different type of antiobiotic? time for er?

Typically : Typically sinus infections are treated for a minimum of ten days. If he is still having fever after 7 days then the antibiotics were not sufficient to cover his infection or the treatment was not long enough. He needs to be reevaluated. He should follow up with his primary care provider, if he is unable, an urgent care is a good choice. Good luck.
