The symptoms are treated as necessary:

• Take acetaminophen (Tylenol) or ibuprofen (Motrin) by mouth for fever and discomfort as the doctor recommends.
• Increase fluid intake, especially cold milk products. Gargle with cool water or try eating popsicles. Avoid hot beverages and citrus fruits.
• Eat a non-irritating diet. (Cold milk products, including ice cream, are often the best choices during herpangina infection. Fruit juices are too acidic and tend to irritate the mouth sores.) Avoid spicy, fried, or hot foods.
• Use topical anesthetics for the mouth (these may contain benzocaine or xylocaine and are usually not required).

The illness normally clears up within a week.

Dehydration is the most common complication, but it can be treated by your doctor.

Call your health care provider if:

• Fever, sore throat, or mouth sores last for more than 5 days
• Your child is having trouble drinking liquids or looks dehydrated
• Fever becomes very high or does not go away
