After lavaging the stomach, give activated charcoal if the patient is alert. Provide oxygen via a mask if the animal is dyspneic. Then start diuresis at 1.5 times maintenance. 4MP is a noncompetitive inhibitor of alcohol dehydrogenase, decreasing the metabolism of methanol. 4MP is for use in dogs only.
Ethanol competes with alcohol dehydrogenase to prevent the formation of the toxic metabolites.
The biggest problem to overcome is the metabolic acidosis. Watch for signs of overhydration like chemosis, increased lung sounds or increased central venous pressure. Prognosis depends on the severity of toxicity. It is considered fair to good for animals that are still pretty alert. It is considered poor for cases with coma or convulsions.
