Differential Diagnosis for Drug-Induced Seizures in WW
Single Most Likely Diagnosis
- Cefepime: Cefepime is a fourth-generation cephalosporin antibiotic known to cause seizures, particularly in patients with renal impairment or when administered in high doses. Its neurotoxicity can lead to seizures, making it a prime suspect in this case.
Other Likely Diagnoses
- Levothyroxine: Although less common, high doses of levothyroxine can lead to seizures, especially if thyroid hormone levels become excessively elevated. This could be a consideration if WW's thyroid hormone levels are not well-controlled.
- Tirzepatide: While less commonly associated with seizures compared to cefepime, tirzepatide, a glucagon-like peptide-1 (GLP-1) receptor agonist, has been reported to have neurological side effects. However, its association with seizures is not as well-documented as with cefepime.
Do Not Miss Diagnoses
- Metoprolol: Beta-blocker overdose can lead to seizures, although this is more commonly seen with intentional overdoses rather than therapeutic doses. It's crucial to consider metoprolol, especially if there's any suspicion of overdose or significant drug interaction that could elevate its levels.
- Acetaminophen: While acetaminophen toxicity is more commonly associated with liver failure, in rare cases, especially with severe overdose, it can lead to seizures. Given the potential for acetaminophen to be taken in overdose quantities, either intentionally or unintentionally, it's a diagnosis that should not be missed.
Rare Diagnoses
- None of the listed medications are commonly associated with seizures as a rare side effect without other predisposing factors (e.g., overdose, renal impairment). However, it's essential to monitor all medications for unexpected side effects, especially in hospitalized patients with complex medical regimens.
