Jeszel, my 6 year old, has been on Gabapentin for over a year now, which has helped her scratching and other SM symptoms. She started at 100mg every 8 hours (300mg per day), but still had symptoms. My neurologist has her up to 600mg per day for the past 6 months, but recently said that we can increase it to 900mg per day as she is still having a scratch episode 1-3 times per day. He said that it can be divided up per day any way I wish. I tried adding in a diuretic, prilosec and tagament, but none of these improved her situation or had a side effect.
I was giving Jeszel 200mg of Gabapentin every 8 hours, but she still had symptoms, so I'm currently giving her 100mg every 4 hours as I feared that it did not last in her system long enough. There was a little improvement. I do this by using pill pockets and a auto timer feeder that opens in the middle of the night or while I'm at work, etc. Jeszel actually found the pill timer feeder fun and makes sure to sleep near it in my bedroom so that she does not miss it opening at 3am.
As she is still scratching at her head and neck every day, my neurologist said to up her to 300mg every 8 hours, but I worry that it will wear off before the next dosage. I'm considering giving her 200mg every 6 hours instead, which he said is fine as well. 300mg capsules do cost the same as the 100mg capsules, so it would be 1/3 cheaper.
Any experience with how long the Gabapentin dosage lasts in your dogs and whether every 6 or 8 hours matters?
I really would appreciate any feedback. Thanks!
