24/7 Emergency Care. Our patients are first.
It’s scary — and you don’t always know what it was.
The safest first step is simple: get the item away, don’t force vomiting, and get expert guidance fast.
Call 911 or go to the ER immediately if your child:
Has trouble breathing, severe wheezing, or can’t catch their breath
Collapses, has a seizure, or can’t be awakened
Is very drowsy, severely confused, or “just not acting right”
Has repeated vomiting, severe belly/chest pain, drooling, or trouble swallowing after an ingestion (especially concerning for foreign body like a battery)
Swallowed a button battery or a magnet (even if they look fine) — do not wait for symptoms
If your child is awake, breathing normally, and has mild/no symptoms:
Call Poison Help: 1-800-222-1222 for free, confidential, expert guidance (24/7). They’ll tell you exactly what to do next based on what was swallowed, how much, and your child’s age/weight.
Important: Don’t induce vomiting. “Ipecac” is not recommended.
What to do immediately (before you call)
Remove the substance/object from your child’s reach.
If there’s anything in the mouth, wipe/rinse it out.
Do not try to make your child vomit.
Call Poison Help (1-800-222-1222) — or 911 if severe symptoms are present.
Be ready to share: age/weight, what was swallowed, how much, when it happened, and symptoms. If you have the bottle/packaging, keep it nearby.
If it’s a burning/caustic product and your child is awake and able to swallow, Poison Control first-aid guidance may include a small amount of water or milk — but don’t improvise; follow Poison Control’s instructions.
Ingestions that are “ER now” even if your child looks okay
These situations can become dangerous fast, and symptoms may not show up right away:
Button batteries (including “coin” batteries) — can cause serious injury in a short time; urgent evaluation and imaging are often needed.
Magnets (especially more than one, or a magnet + metal) — can trap bowel tissue and cause severe internal injury.
Unknown substance or missing pills (you’re not sure what or how much was swallowed)
Strong household chemicals (drain cleaner, oven cleaner, concentrated cleaners)
What Post Oak ER can do for suspected ingestion (Houston)
If Poison Control advises emergency evaluation — or your child has red-flag symptoms — Post Oak ER can provide:
Rapid assessment and monitoring (airway, breathing, circulation)
On-site X-ray to locate swallowed foreign bodies when indicated (common for batteries/magnets)
IV treatments for dehydration, nausea/vomiting, and supportive care
Escalation of care if breathing or neurologic symptoms are present
Walk in 24/7 — no appointment needed.
Prevention that actually works
Store medicines and chemicals locked and out of reach
Keep products in original containers
Remind visitors to keep purses/bags (meds, gummies, vape liquids) out of reach
