Cautions
Caution in hepatic and renal impairment
Elderly patients are at increased risk for comorbidities related to anticholinergic effects; may be potentially inappropriate in this population (Beers criteria)
Effects of ethanol and other sedative drugs may be potentiated when used concurrently
Benzyl alcohol, which is associated with the fatal toxicity, gasping syndrome in neonates; use caution
Some products may contain phenylalanine
Pregnancy & Lactation
Pregnancy category: B
Lactation: Excreted in breast milk; avoid (AAP Committee states compatible with nursing)
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
