This NHS content is written for people in England. Medicine names, availability, prescribing and services may differ in other countries.

Who can take simeticone

Most adults and children, including newborn babies, can take simeticone.

Who may not be able to take simeticone

Simeticone is not suitable for some people. To make sure it's safe for you or your child, tell a pharmacist or doctor if you (or your child):

  • have ever had an allergic reaction to simeticone or any ingredients it is combined with
  • are having treatment for a thyroid problem

Simeticone often comes combined with other ingredients. It's important to read the leaflet that comes with the medicine, or the information printed on the box or bottle, to make sure the medicine is suitable for you or your child.

If you're not sure, ask a doctor or a pharmacist for advice.
