Treatment

The vet will always try to remove the ingested poison from the body and alleviate the specific symptoms of poisoning.

There are different methods to remove the poison from the body:

1. ACTIVATED CHARCOAL: Activated charcoal can absorb toxins. If possible, it should be administered within 2 hours after ingestion of the poison, so that the toxin does not enter the bloodstream.
2. LAXATIVES: The vet may combine the administration of activated charcoal with a laxative.
3. VOMITING: The vet can also induce vomiting using medication to remove the toxin from the body. 

To alleviate the symptoms of mezereum poisoning, the affected skin areas can be rinsed with water and the vet can administer infusions. In addition, diuretic medication can be prescribed.
