I was recently asked if a popular dewormer for humans can be used on animals. Apparently someone had written in a public blog that it can be used.
Of course being not a vet, I did not know the answer, so I asked our vet.
This evening, he showed me the book of drugs for animals from the British Small Animals Veterinary Association. Based on the main ingredient in this popular dewormer, it can be used on animals, but it has to be administered in low dosage over a period of 5-10 days and not given at one go (as in the case with humans). Despite that, there are still contraindications which suggest that this dewormer might not be very suitable for animals. Like it or not, humans and animals are biologically different, hence, our medicines should not be shared.
I have also heard animal rescuers advising other rescuers what medication to self-administer on sick pets.
There are risks in self-prescribing when we are not vets. We might not know the correct dosage and proper way of administering these drugs. Sometimes the presence of just one ingredient could make a whole world of difference to the overall effect of the drug.
A case in point was this lady who had administered Ivermectin on her kittens, but had used a disastrously high dosage. Her kittens died.
Please do not self-prescribe medicine to the animals under your care unless you are a vet or have informed pharmaceutical knowledge on the medication.
Always consult your vet for a proper diagnosis and proper medication. That's what they are there for!
