**Core Concept**
Ipecac syrup is an emetic used to induce vomiting in the treatment of certain poisonings, but its use is limited due to potential complications and contraindications. The decision to use ipecac syrup involves weighing the benefits against the risks, particularly in pediatric patients.

**Why the Correct Answer is Right**
The primary contraindication to ipecac syrup use in pediatric patients is the risk of aspiration, which can lead to respiratory complications. In children under 1 year of age or with an altered level of consciousness, the gag reflex may be impaired, increasing the risk of aspiration. Additionally, ipecac syrup can cause gastric distension and potentially lead to rupture, particularly in children with pre-existing gastrointestinal conditions.

**Why Each Wrong Option is Incorrect**
**Option A:** Aspiration pneumonia is a potential complication of ipecac syrup use, but it is not the primary contraindication in pediatric patients.
**Option B:** While ipecac syrup can cause gastric irritation, this is not a contraindication in pediatric patients.
**Option C:** Ipecac syrup is not contraindicated in children with a history of seizure disorders; in fact, it may be used cautiously in such cases.

**Clinical Pearl / High-Yield Fact**
In pediatric patients, ipecac syrup should be used with caution and only in cases where the benefits outweigh the risks. The American Academy of Pediatrics (AAP) recommends against the routine use of ipecac syrup in children and instead advocates for supportive care and gastric decontamination.

**Correct Answer:** C.
