Imidazoline decongestants are a topical vasoconstrictor (constricts blood vessels). When a bottle of eye drops are chewed, it can result in severe poisoning in pets – even death, when untreated. Clinical signs of vomiting, lethargy, depression or agitation, ataxia, hypotension, and a life-threatening low heart rate can be seen. Immediate veterinary attention should be seen. When in doubt, contact your veterinarian or Pet Poison Helpline for life-saving advice to find out if these common eye drops are poisonous to your pet.
