Toxicity to pets
Imidazolines are chemicals often found in decongestant nose sprays and eye drops that reduce redness in the whites of the eyes. Imidazolines are very potent and even small amounts when ingested lead to gastrointestinal signs (e.g., drooling, vomiting), cardiovascular signs (e.g., low heart rate, low blood pressure), neurological signs (e.g., lethargy, stumbling, collapse) and death in companion animals.
