Follow-up Treatment for Strep Throat
A person who has strep throat remains contagious until he/she has been on antibiotics for 13 days. Do not return to school, daycare, or work until the fever is gone and you have been taking the antibiotic for at least 24 hours.
If fever does not go away within 2 or 3 days, or if you don't seem to be getting better or are feeling worse, contact your doctor. A small percentage (about 5 percent) of strep throat cases are caused by bacteria that are resistant to the first antibiotic. If you're not improving, a different antibiotic may be necessary.
To help prevent the spread of strep throat, do not share eating utensils, dishes, drinking glasses, or towels. Wash utensils in hot, soapy water after each use.
Once your child has been on antibiotics for a few days, replace his or her toothbrush with a new one. Strep bacteria can survive on the toothbrush and re-infect the child after the course of antibiotics is complete.
