Children at highest risk for seizure activity after ingestion are those who have swallowed which substances?

Children who have ingested drugs and insecticides are indeed at the highest risk for seizure activity. This is largely due to the neurotoxic effects that many of these substances can have on the central nervous system. Certain drugs, especially those not intended for pediatric use, can have a direct impact on brain activity, leading to seizures. Additionally, insecticides often contain potent neurotoxins that disrupt normal neuronal function and can lead to seizure activity upon ingestion.

The other categories mentioned, while they can potentially cause adverse effects, typically do not have the same immediate and severe impact on the neurological system that drugs and insecticides do. For instance, household cleaners and food allergens may lead to other health issues but are less likely to cause seizures directly. Vitamins and supplements, although overdoses can lead to toxicity, are generally not associated with seizures at typical dosages of common products. Similarly, over-the-counter medications and antibiotics may cause side effects, but they usually do not present the same level of risk for seizures when compared to drugs and insecticides.
