Give half pill of Iverhart?

Species: Dog
Breed: Chinese Crested (Hai
Age: 2-5 years
I purchased Iverhart Plus heartworm pills for dogs up to 25 pounds. Since my two dogs only weigh 8.5 pounds each, wouldn't it be OK to cut the pill in half and give each dog a 1/2 pill each month?




Online vet, Dr. Marie

Dr. Marie replied:

We don't usually recommend splitting up heartworm medication. If the medication is not meant to be split in half, then you don't know if the medicine is evenly divided amongst the whole pill. You may find that one half of the pill has 90% of the medicine in it and the other half has only 10%. It really is best to use the full pill as prescribed.
