Baby’s First Medications: “Eyes and Thighs”

Soon after birth, usually in the delivery room, we will ask your permission to give your baby their first medication. Read more to learn about why we recommend these treatments for all babies.

Topic: Postpartum

There are two treatments we give babies right after they are born:

  1. Erythromycin Eye Ointment
  2. Vitamin K injection

You might hear health care professionals call this “eyes and thighs.” Erythromycin is an ointment that gets spread in the eyes. Vitamin K is a one-time shot that goes in the thigh.

Hence, eyes and thighs.

What does erythromycin eye ointment do?

Infections in babies can become serious quickly. That is because their immune systems are not very well developed. Some infections can cause eye damage and blindness, and erythromycin can treat those infections. It gives the baby a way to avoid unhelpful bacteria.

How does Vitamin K help?

Vitamin K is a vitamin, one that infants don’t have a lot of when they are born. It is helpful in creating blood clots, and without it babies are at risk of bleeding. This bleeding might not occur in the hospital, and could occur weeks later. One injection of vitamin K can remind the body how to clot blood and it’s important for baby to get that boost!
