Accidental ingestion/Ingestion accident.
(eg. description of the frequency and severity of the symptoms
On September 12, 2018, the dog took about 3 licks of this product that was on a plate. About an hour later, the dog developed head shaking and then about 45 minutes later, the dog developed tremors. The owner then contacted the Animal Product Safety Service (APSS). The APSS veterinarian stated that methomyl is a carbamate that is rapidly absorbed after ingestion, but does not accumulate in the tissues. The APSS veterinarian also stated that it does not "age" on the receptors like organophosphates (OP's) do, so signs are often short-lived. The APSS veterinarian continued by stating that signs occur within minutes after ingestion, and include salivation, lacrimation, urination, diarrhea, dyspnea and emesis (SLUDDE) signs, bradycardia, ataxia, weakness, tremors, seizures, and possibly death. The APSS veterinarian recommended the owner take the dog to a veterinarian, have the veterinarian call for information, have the veterinarian provide a physical examination, and to manage tremors (if seizuring on arrival, start with an anticonvulsant for the seizures). Soon after, the regular veterinarian contacted the APSS to continue the case. The APSS veterinarian recommended the regular veterinarian provide atropine cholinergic toxicity (If needed for bradycardia. Atropine sulfate (0.1 - 0.2 milligrams per kilogram (mg/kg) for dogs) is given to control muscarinic signs. Give 1/4 of the initial dose intravenously (IV) and the rest intramuscularly (IM) or subcutaneously (SQ). The dose can be repeated as needed, but do not over-atropinize the animal. The primary goal of atropine use is to control bradycardia and bronchial secretions.), monitor at the veterinary facility, monitor heart rate, provide symptomatic care, provide supportive care, and to call back with questions. Soon after, the owner contacted the APSS with an update. The owner stated that the dog was no longer doing any head shaking or tremoring. The APSS veterinarian stated that methomyl toxicity can be severe (sometimes even fatal within 30 min), but no long term effects are expected and the duration of signs is relatively short lived.
Moderate
On September 14, 2018, an APSS assistant called to follow up on the case. The owner stated the dog had an isolated event of diarrhea on September 13, 2018, but no other signs developed. This was off label use, this product should not be anywhere pets may have access to.
