Vitamins come in a variety of forms (gummies, chewable tablets, capsules) and are appealing to children as some of them are flavoured to taste like candy. Large, one-time ingestions of multivitamins are generally not a problem unless they contain iron, which can cause toxicity in smaller amounts. Vitamin A can be concerning, but usually requires a very large ingestion to result in toxicity.

Poisoning Risk

Low, unless vitamins contain iron.

Expected Symptoms

  • Possible upset stomach (discomfort, nausea, isolated episode of vomiting or diarrhea.
  • Stomach symptoms may be more severe if iron ingested.
