What symptoms can occur due to a Dilantin (Phenytoin) overdose?

A Phenytoin (Dilantin) overdose can lead to a variety of symptoms due to its effects on the central nervous system and cardiovascular system. The correct choice indicates symptoms such as supraventricular tachycardia (SVT), coma, and confusion, which are notable manifestations of toxicity associated with this medication.

Phenytoin is primarily used as an anticonvulsant, and in overdose situations, it can disrupt normal brain function. The presence of SVT suggests a risk of tachyarrhythmias that can occur with elevated serum levels of the drug. Additionally, confusion and coma signify the potential for severe neurotoxicity as Phenytoin can impair cognitive function and consciousness sharply at high doses.

Understanding the pharmacological profile of Phenytoin is crucial in recognizing such overdose symptoms to deliver appropriate interventions in a critical care setting.
