Boomie started having seizures last week.   My vet started him on Gabapentin.   I’m not sure how effective it is, because he still has lots of little “spells” but at least the grand mal seizures have stopped for now.  Anyway, I am noticing that for the past few days, since he’s been on this drug, he has also been drinking more, and peeing more.   I couldn’t find anything that says this is a typical side effect of Gabapentin, so I thought I would check to see if anyone else has had this same experience.  If it’s not the drug, is there something else going on that might be causing both the drinking/peeing and the seizures?

The only thing I can think of is to check his blood sugar.  Diabetes can cause thirst/excess urination.  If that turns out ok, then maybe the vet can try phenobarbital instead of gabapentin.  I think most dogs that have siezures take phenobarb, unless it doesn't work, then they"ll try something else (like the gabapentin.)  Hope it's nothing serious.

Wouldn't you know it, my vet won't be in till Friday.  I guess I can ask the relief vet tomorrow (or the Doctor du Jour as I like to say).

He's getting the capsules.

The seizures started last week.  (Booomie is about 12 1/2) He did have a basic, non-fasting blood test on Friday.  It showed one liver value that was slightly high, but everything else was normal.  He had been on Metacam for over 3 years, and Tramadol for over one year, but we have stopped the Metacam and cut back on the Tramadol for now.   He has not had steroids.

This morning Boomie's excessive thirst and urination seem to be subsiding.  He is also having fewer seizures.  Most importantly, he is acting like his normal self.   I don't know why my vet didn't want to use those other drugs, unless she felt they might leave him too sedated or something.  I will be in contact with her soon.  Thanks.
