Call Poison Control at 1-800-222-1222 if you gave your child a double dose of Motrin (ibuprofen). The risk is real but generally lower than a double dose of Tylenol, since ibuprofen mainly affects the kidneys and stomach rather than the liver, and the margin before serious toxicity is wider. Still, don't guess. Let Poison Control confirm based on your child's weight and the amount given.

Where Ibuprofen Fits Between Amoxicillin and Tylenol
If you've read our other double-dose guides today, a pattern is emerging: "double dose" means something different for every drug. Amoxicillin has a wide safety margin. Acetaminophen (Tylenol) has a narrow one, with liver injury that can take a day or more to show up. Ibuprofen sits in its own place: a wider margin than acetaminophen, but a genuinely different organ at risk.
A review of NSAID risk in pediatric medicine puts real numbers on this. Symptoms of severe ibuprofen toxicity are uncommon in children below 100 mg per kilogram ingested over the course of treatment. Ingestion above 400 mg per kilogram is associated with a much higher risk of severe or life-threatening effects. That's a wider range than the acetaminophen threshold covered in our Tylenol guide, but it's still a real threshold, which is why the call still matters. This is a different situation from not being sure whether a dose was given at all, or from deciding whether to redose after your child threw up: here, you already know two doses went in.
Is This a True Double Dose, or a Concentration Mix-Up?
Before anything else, check the bottle.
Ibuprofen for infants comes as concentrated drops: 50 mg per 1.25 mL. Ibuprofen for children comes as a suspension: 100 mg per 5 mL. Do the math and the infant drops are twice as strong per milliliter. According to the ISMP-affiliated National Poison Control resource, giving the infant drops using a children's-suspension amount delivers double the intended dose, and the two bottles are commonly stocked side by side with packaging that can look similar.
If your double dose happened because the wrong bottle got used, that's a different math problem than giving the same product twice in a row. Tell Poison Control which product was involved. They'll calculate accordingly.
| Product | Concentration | What it means |
|---|---|---|
| Infant ibuprofen drops | 50 mg per 1.25 mL | Twice as concentrated per mL as children's suspension |
| Children's ibuprofen suspension | 100 mg per 5 mL | Standard concentration for ages 2-11 |
What Ibuprofen Actually Affects
Fever medicines get lumped together, but they don't cause the same kind of harm. Acetaminophen's risk is to the liver. Ibuprofen's risk is mainly to the kidneys, plus the stomach.
According to the same pediatric NSAID review, the main concern with ibuprofen overdose is acute kidney injury, which happens through reduced blood flow to the kidneys and a reaction called acute interstitial nephritis. Gastrointestinal bleeding and low platelet counts are additional risks at higher doses. The FDA label lists stomach-bleeding warning signs specifically: feeling faint, vomiting blood, black or bloody stools, or stomach pain that doesn't improve.
This is why the Tylenol and Motrin guides don't just swap the drug name. What to watch for is genuinely different.
What to Watch For
| Symptom | Possible concern | What to do |
|---|---|---|
| No symptoms at all | Common, especially for smaller overages | Still call Poison Control to confirm, then watch |
| Stomach pain, nausea | GI irritation | Mention it on the call; watch for worsening |
| Vomiting blood, black or bloody stools | Possible stomach bleeding | Call Poison Control or your doctor right away |
| Little or no urination, unusual swelling | Possible kidney effect | Call your doctor promptly |
| Severe drowsiness, difficulty breathing | Medical emergency | Call 911 |
Steps to Take Right Now
- Call Poison Control at 1-800-222-1222. Have the bottle in hand.
- Check which product was used. Infant drops or children's suspension? This single detail changes the calculation.
- Note the timing and amount. When was each dose given, and how much?
- Skip the next scheduled dose unless told otherwise. Don't stack another dose on top while waiting for guidance.
- Watch for the specific warning signs above over the next day, particularly stomach or urination changes, not just how your child seems in general.
If the mix-up happened around a fever medicine other than ibuprofen, see our Tylenol double-dose guide instead, since the risk and the response are different. And if this happened alongside an antibiotic rather than a fever reducer, our amoxicillin double-dose guide and the general missed antibiotic dose for a child cover that territory. Ibuprofen comes up in other timing questions too, like our guide on ibuprofen and alcohol for the adult version of spacing questions.
How Pillo Helps Prevent This
A double dose usually comes down to one thing: no shared, reliable record of what was already given, especially on a sick day when a child is getting fever medicine from more than one caregiver, or when two different concentrations of the same drug are sitting in the same medicine cabinet. Pillo's persistent alarm marks a dose as taken the moment you log it, so checking the app before the next round shows you whether that dose already happened, instead of relying on memory during a stressful day.
Download Pillo on Google Play to keep a clear log of every dose given, especially when more than one fever medicine or concentration is in play.
Frequently Asked Questions
Is a double dose of Motrin dangerous for a child?
It can be, though the margin is generally wider than for acetaminophen. A review of pediatric NSAID risk notes severe toxicity is uncommon below 100 mg per kilogram, with higher risk above 400 mg per kilogram. Call Poison Control at 1-800-222-1222 so they can calculate your child's actual risk using their weight and the amount given.
What are the symptoms of too much ibuprofen in a child?
Watch for stomach pain, vomiting (especially if it looks bloody), black or tarry stools, reduced urination, or unusual swelling. These point to the two main risks: stomach bleeding and kidney effects. Severe drowsiness or trouble breathing means calling 911.
Is ibuprofen more or less dangerous than Tylenol for a double dose?
Ibuprofen generally has a wider margin before serious toxicity than acetaminophen does, and it affects different organs (kidneys and stomach rather than liver). That doesn't make a double dose harmless; it means the specific warning signs and the urgency differ. See our Tylenol double-dose guide for that comparison.
Could this have been a concentration mix-up instead of a true double dose?
It's worth checking first. Infant ibuprofen drops (50 mg per 1.25 mL) are twice as concentrated as children's suspension (100 mg per 5 mL). Using the infant drops at a children's-suspension amount effectively doubles the dose. Tell Poison Control which product was used so they can calculate the actual amount.
Should I give the next scheduled dose on time after a double dose?
Don't decide this yourself. Skip the next dose unless Poison Control or your pediatrician tells you otherwise. Stacking another dose on top while your child's body is still processing the excess isn't the move.
My child seems fine. Do I still need to call?
Yes. Many double doses don't cause visible symptoms, but that's not something to assume in advance, especially with the stomach and kidney risks specific to ibuprofen. Call Poison Control to confirm rather than waiting to see how your child does.
