propylene glycol poisoning in dogs

Dr. Hotchkiss says that what makes ethylene glycol such a dangerous and common form of poisoning is that the toxin’s sweet smell and taste appeals to an animal’s sweet tooth. Although less toxic than EG, ingestion of propylene glycol (PG) may be associated with a toxic syndrome similar to the acute phase of EG toxicosis. If cats or dogs ingest large amounts of propylene glycol, poisoning can occur.. Share this support centre article. DEG is less toxic than ethylene glycol in most species, but more toxic than propylene glycol. If the above wasn’t enough, polyethylene glycol also destroys the beneficial bacteria found on your dog’s skin and inside their stomachs.

Should a dog lick up some concentrated Propylene Glycol – even 1 to 1.5 teaspoons full – that can be enough to begin to cause issues. Antifreeze poisoning in dogs is a very serious matter. Dogs rely on these bacteria for a healthy immune system and a balanced pH level. Therefore, now the ethylene glycol has been replaced with propylene glycol. Yet because of its proven ability to cause a serious type of blood disease in some animals — Heinz body anemia — propylene glycol has been banned by the FDA for use in cat food. Toxicity and death may occur after drinking even a small amount. Fomepizole (Antizol-Vet®, 4-methylpyrazole) is the treatment of choice for ethylene glycol poisoning in dogs. When dogs or cats are exposed to a toxic dose of ethylene glycol, immediate treatment is necessary. Most intoxications are associated with ingestion of antifreeze, which is typically 95% EG. Prevention is key. Antifreeze poisoning is the most common poisoning of dogs and cats in the United States. 12 Almost all (98%) affected children died in a 1996 epidemic in Haiti. Long term outcomes may include kidney failure and brain damage. Dogs usually come into contact with antifreeze when it leaks from a car's engine onto the ground, when it is spilled onto the ground while being added to a car's engine, or when the container is left uncapped. It is given intravenously for 36 hours, and stops the metabolism of ethylene glycol into its damaging metabolites. Large doses and unusual circumstances are necessary for the development of propylene glycol toxicity. 13 Propylene glycol poisoning is marked initially by CNS depression and an elevated osmolal gap and, later, by an increased anion gap. Ethylene glycol is especially dangerous since it only takes about 3oz to poison a medium-sized dog. Many dog owners know that antifreeze is poisonous to dogs, but not all people understand how dangerous antifreeze poisoning can really be.Unfortunately, exposure to even a small amount of toxic antifreeze can quickly lead to death.

Propylene glycol (IUPAC name: propane-1,2-diol) is a viscous, colorless liquid, which is nearly odorless but possesses a faintly sweet taste.Its chemical formula is CH 3 CH(OH)CH 2 OH. Zinc, copper, and naphthalene poisoning are other types that will need to be ruled out. Automotive antifreeze kills 10, 000 of these pets every year. It is believed that background concentrations of ethylene glycol in air, soil, surface and groundwater do not lead to poisoning. Experts note that factors that affect the risk of poisoning when exposed to ethylene glycol include its dose, duration and nature of contact. Propylene glycol antifreeze products are more environmentally friendly, and in addition to being less likely to cause fatal poisoning, they don’t taste like candy the way ethylene glycol products do, so … The most toxic kind contains ethylene glycol, but some contain methanol or propylene glycol, which may not be as toxic but can still make your dog unwell.

Marketed as smoke-free substitutes for traditional cigarettes, they’re shaped like a long cigarette, battery operated, and filled with a replaceable cartridge of E-liquid that contains a mixture of ingredients such as nicotine, flavorings, glycerin and propylene glycol. There are a few differential diagnoses of chive poisoning in dogs. Propylene glycol is a controversial additive used to help preserve the moisture content in some commercial dog foods.. You may already recognize this chemical for its more everyday use — as the key component in newer automotive antifreeze.. It is a colorless, odorless, and sweet-tasting solution. Y1 - 2011/12. It has occasionally been substituted for propylene glycol in pharmaceutical preparations, resulting in the deaths of more than 100 persons in some incidents. Early symptoms include intoxication, vomiting and abdominal pain. AU - Claus, Melissa A.

Antifreeze poisoning in dogs is a very serious matter. 2 – 11 The most recent mass DEG poisoning occurred in India in 1998. Ethylene Glycol Poisoning in Dogs (In addition to being found in the car's engines to prevent freezing and overheating, it is used in hydraulic brake fluids.) Later symptoms may include a decreased level of consciousness, headache, and seizures. The oral LD 50 of PG in dogs is ~9 mL/kg. Over 10,000 dogs and cats are poisoned with automotive antifreeze each year. Ethanol is the treatment of choice for cats and is administered for up to 64 hours. Propylene glycol, although not entirely nontoxic, is considerably less toxic than ethylene glycol and has been reported to affect the central nervous system but not the kidneys. Until 1996, almost no data existed on the incidence of ethylene glycol (antifreeze) poisoning. Propylene glycol products are biodegradable, anti-corrosive, and recyclable. Propylene glycol is a commonly used solvent for oral, intravenous, and topical pharmaceutical preparations. Propylene glycol (PG) is one of the least toxic glycols.. Cats are particularly sensitive to PG and its use is no longer allowed in cat foods. These 95% commercial antifreeze preparations are diluted ~50% with water when used in vehicle cooling systems.

Antifreeze poisoning in dogs. The ingredient found in antifreeze that is poisonous to dogs and cats, is ethylene glycol, which make up 95 percent of the antifreeze. Propylene glycol toxicity is metabolized to compounds that are normal constituents of the citric acid cycle. Containing two alcohol groups, it is classed as a diol.It is miscible with a broad range of solvents, including water, acetone, and chloroform.In general, glycols are non-irritating and have very low volatility. Ingestion of ethylene glycol (EG) is a frequently encountered toxicity in dogs and cats. To the authors' knowledge, this is the first report of documented propylene glycol intoxication in a dog, as well as the first report to describe hemodialysis as treatment for propylene glycol intoxication in a dog. Some “pet-safe” antifreeze products contain propylene glycol, which is much safer than ethylene glycol if ingested. However, propylene glycol is considerably safer (less toxic) than its far more dangerous cousin — ethylene glycol. According to vetinfo.com, antifreeze poisoning in dogs and cats is the most common form of poisoning in the United States. A dog only needs to ingest 2 to 3 milliliters of ethylene glycol per pound of body weight to get a lethal dose of the toxin; cats only need to ingest 0.64 milliliters for the same effect. “Propylene glycol ingested at toxic doses can cause central nervous system depression and lactic acidosis, Brutlag says. Propylene glycol is an effective alternative to ethylene glycol and the FDA has recently labeled propylene glycol safe.

Many dog owners know that antifreeze is poisonous to dogs, but not all people understand how dangerous antifreeze poisoning can really be.Unfortunately, exposure to even a small amount of toxic antifreeze can quickly lead to death. Underlying renal insufficiency and hepatic dysfunction raise risk for toxicity. Ethylene glycol poisoning is common because antifreeze is widely used, it has a sweet taste and small lethal dose (only 3 to 4 teaspoons in dogs, 1 to 2 teaspoons in cats), and it is often stored and disposed of improperly. The dog made a full recovery. All animals are susceptible to ethylene glycol (EG) toxicity, but it is most common in dogs and cats.
