The first time was a 60 pill bottle of 150mg Wellbutrin (bupropion) and the second was a 15 pill bottle of 5mg Abilify (aripiprazole). We did what normal adults do in the 21st century: we googled canine drug overdoses before actually calling a veterinarian so that we wouldn't sound silly.
There isn't that much information available for human overdoses, let alone for dog overdoses. This became apparent when I called an emergency veterinarian and they basically said that they had no idea.
I turned to my go-to source for medical papers, the NIH's PubMed site (http://www.ncbi.nlm.nih.gov/pubmed).
The first time was the Wellbutrin
- 9g overdose in adult female - non-fatal, but with complications
- 23g overdose in adult male - fatal
Assume a woman weighs 150lb (68kg), and you get a non-fatal dose at 0.13g/kg.
Assume a man weights 190lb (86kg), and you get a fatal dose at 0.27g/kg.
So in the case of Seamus, a 75lb (34kg) "puppy:"
7 pills * 150mg = 1050mg = 1.05g
He could have had, at most (0.03g/kg). So all in all, it was going to probably be OK. As I was multiplying this out, my sister-in-law found six pills under the dresser, and we relaxed a lot more.
As I write this, I realize that the woman probably has the exact same prescription I do.
A week later, he got the bottle of Abilify, and I found a report of a 2.5 year old kid taking 195mg.
15 pills * 5mg = 75mg
I didn't even do further math, as he took about 2.5 times less than a child he is probably about twice the size of.
