However, if stomach upset occurs, give it with a small amount of food. Erytas 125mg Tablet is usually given four times a day. Since the dose depends upon the type of infection, its severity, and your child’s age and body weight, make sure to stick to the dose, time, and way prescribed by the doctor.

Ensure that your child completes the full prescribed course of the medicine as stopping it abruptly may worsen your child’s condition or increase the risk of reinfection.
