If Your Child Gets a Double Dose of Medicine: What Parents Should Do

Quick Answer: What To Do If Your Child Gets a Double Dose of Medicine

If your child accidentally receives an extra dose of medicine, contact Poison Control at 1-800-222-1222 (US) right away for guidance, even if your child seems fine. You can also contact your child's pediatrician or pharmacist, but Poison Control is available 24 hours a day.

• Have the medication bottle, dose, time given, and your child's age and weight ready.
• Ask for guidance before giving the next scheduled dose.
• If your child has trouble breathing, has a seizure, collapses, or cannot be awakened, call 911 immediately.

The safest next step depends on the specific medicine, amount taken, and your child's individual circumstances.

Long Answer: Accidental Extra Doses Explained

Children may need medicine for many reasons. Sometimes it's occasional. Your child has a high fever and refuses to eat or drink. To keep them comfortable and prevent dehydration, doctors often recommend ibuprofen or acetaminophen. 

Sometimes they require an occasional antibiotic when kids catch those unavoidable childhood bugs like strep throat. Other children may have a chronic condition that needs daily medication.

While the general advice is to give kids the least amount of medicine for the shortest time needed, giving medicine to children is inevitable and will likely happen to every family at some point! During illnesses such as fevers, colds, or allergies, children may need medication multiple times a day. 

Unfortunately, dosing errors do happen. In our household, both parents work in the medical field, and it still occurred to us! Two caregivers might give the same medication without realizing it, a dose could be repeated after vomiting, or the timing between doses might be off.

One common dosing mistake is accidentally taking a double dose. An accidental double dose of medicine in children can be frightening for parents. It's happened to me (with cetirizine), and immediate panic sets in! 

The main point is that parents should always consult a healthcare professional if a dosing mistake occurs. This includes accidental double doses.

In many cases, the situation might not be dangerous, but a pediatrician, pharmacist, or Poison Control specialist should determine the safest next step. My advice is not to panic, but also don't try to handle it alone! 

Why Accidental Double Doses Happen

Medication errors at home are common and can occur in any family. All caregivers make mistakes sometimes. 

Situations that may lead to a double dose include:

• Two caregivers giving the same medication unknowingly
• Forgetting when the last dose was given (hello, sleep deprivation!)
• Giving medicine early because it doesn't work or symptoms return
• Repeating a dose after vomiting or spitting out medicine, without realizing that most of the dose was actually absorbed
• Confusing medications that look or sound similar 
• Accidentally giving a combination product that contains an ingredient you've already given (like acetaminophen in a cough or cold medicine) 

What To Do If Your Child Gets a Double Dose of Medicine

If you believe or suspect your child received an extra dose of medication, the safest course of action is to contact a medical professional for guidance.

You can call:

• Your child’s pediatrician
• A pharmacist
• Poison Control (1-800-222-1222 in the United States)

Poison Control specialists are available 24 hours a day, even when the doctor's office or pharmacy is closed, and they specialize in toxicology (the study of the harmful effects of chemicals or substances in the body). 

Before calling a medical professional, have the following info handy: 

• Name and strength of the medication
• Total amount given
• Time each dose was given
• Your child’s age and weight
• Other medications your child takes or health conditions they have

What to expect after calling Poison Control or your doctor:

When your medical professional has all the information about the double-dose situation, they can give you advice.

Depending on the drug in question and your child, this advice may include: 

• Peace of mind if there's nothing to worry about!
• Monitoring at home (they may give you a list of things to watch for) 
• Advice to come to the doctor or emergency room for a professional assessment
• Advice to call emergency services 
• Next steps: they may tell you to hold the next dose, continue on with regular dosing, etc. 

When To Seek Emergency Medical Care

In some situations, parents should avoid wasting time calling a doctor, pharmacist, or poison control and instead seek emergency care immediately.

Call 911 or go to the nearest emergency department if your child develops symptoms such as:

• Trouble breathing
• Severe vomiting
• Seizures
• Extreme sleepiness or difficulty waking
• Confusion or unusual behavior
• Loss of consciousness

These symptoms might signal a serious reaction or overdose and need urgent medical care. If possible, bring the medication with you. 

Why Professional Guidance Is Important

Unfortunately, there is no single rule for when your child accidentally takes a double dose of medication. Different medications vary greatly in their safety margins and side effects. The danger of a double dose depends on several factors, including:

• The medication involved
• The amount given
• The time between doses
• The child’s age and weight
• Whether other medicines were also taken
• Your child's individual health history and other medical conditions

Because of these variables, a healthcare professional should always assess the situation before deciding whether it's safe to continue monitoring at home and whether your child should receive the next dose as scheduled. 

In many cases, healthcare providers may suggest observation, but a trained medical professional should make that decision.

Medicines That Often Prompt Parent Questions

Acetaminophen

Acetaminophen is often used for fever and pain. Taking too much can cause liver damage, especially if large doses are repeated. A single double dose might not be a concern, but you should seek medical advice.

Ibuprofen

Ibuprofen is generally safe when used correctly, but it may cause stomach irritation or other symptoms if taken in high doses. Contact your provider for medical advice. 

Antihistamines

Medications like diphenhydramine can cause drowsiness, agitation, or other symptoms if taken in large amounts. Contact your doctor, pharmacist, or poison control for guidance. 

Prescription Medications

Prescription medications may have different dosing limits and should always be reviewed by a healthcare professional in case of accidental double doses. Call your pediatrician, pharmacy, or poison control center.

How To Prevent Medication Dosing Mistakes

While mistakes can happen to even the best parents, here are some tips to help prevent accidental double doses of medication in your child. 

• Don't rely on memory; maintain a written log of all doses. There's a saying in the medical field: if you didn't document it, it didn't happen! 
• Make sure all parents and caregivers know about their responsibilities. If multiple adults are giving medicine, communicate that well and use a written log to document each dose.
• Always measure liquid doses with an oral syringe or dosing cup from the pharmacy. Don't use teaspoons or estimate the amounts.
• Keep medicine in its original container.
• Set phone timer reminders for dosing schedules.
• Avoid combination products with multiple ingredients, especially cough-and-cold medicines.
