Melissa, a three year old, has a history or recurrent ear infections. It’s the weekend, it’s one o’clock in the morning and Melissa is irritable, tugging at her right ear and has a slight temperature. This has been the prelude to a spike of 103 F temperature, crying and piercing screams due to her painful ear infections. Her mother has left over liquid antibiotic medication that the child’s pediatrician prescribed six weeks ago for her ear infections. Her mother thinks it over, “Should I give the baby the antibiotic. Is it safe to do so?”
