  • Check your child from head to toe: under the arms, in and around the ears, inside the belly button, behind the knees, in the hair and around the waist
  • Tumble dry clothes on high heat for 10 minutes
  • Check the dog and the daypacks before they come inside
  • Skip oil of lemon eucalyptus and PMD repellents on children under 3

From check-in to care plan: your child's visit

Board-certified physicians lead the team at Urgent Care Center of Westmont, also known as Immediate Care Center of Westmont. A parent or legal guardian checks the child in and gives consent. A clinician then checks vital signs, asks what happened and examines your child, explaining each step.

If a test will change the plan, we may do a rapid strep test, a flu test, a urine test or an X-ray at the Cass Ave clinic. We then recommend treatment, which may include prescription medicine when appropriate, and tell you which changes to watch for at home. Ask for a school note if your child will miss class. The pediatric urgent care service page lists what we treat.

Common questions

My child twisted an ankle at a Darien, IL park. Do we need an X-ray?

Maybe. If your child cannot put weight on it, the pain sits right over the bone, or swelling is severe, have it checked. Go to 29 N Cass Ave, our only clinic with X-ray, which is straight up Cass Ave from Darien, IL.

Which tick repellent is safe for a young child?

The CDC recommends EPA-registered repellents with ingredients such as DEET or picaridin, and says not to use oil of lemon eucalyptus or PMD on children under 3. HealthyChildren.org advises putting repellent on your hands first, then on your child's face, avoiding the eyes and mouth.

How long after a tick bite should I watch my child?

HealthyChildren.org says to call if a fever or rash appears within 4 weeks of the bite. Mark the date on a calendar and check the spot every few days. Come in sooner if the bite looks red, warm and swollen.

Are you open on Sundays for Darien, IL kids?

Yes. Both Westmont, IL clinics are open Saturday and Sunday from 9 AM to 5 PM, and weekdays from 9 AM to 6 PM. Walk in, or check in online for the Cass Ave clinic.

Can the Jewel-Osco clinic check a sports injury?

It can see illness and many minor problems, but it has no X-ray. For a sports injury that might be a break, go to 29 N Cass Ave instead. For a fever, cough or sore throat, either clinic works.
