I'm so sorry about Friday, Terri. Spencer takes 200mg of gabapentin twice a day and 100mg of tagamet three times a day. Tagamet comes in 200mg so I just cut all the pills in half. I really noticed a difference when I started the tagamet. Spencer was diagnosed with a moderate to severe Chiari malformation in February and was on gabapentin alone for the first month. I added the tagamet in mid-March and I've noticed such a difference in his level of scratching. Fortunately he's never yelped or exhibited pain, except when brushing him, but his scratching was terrible. He'd scrach seven to ten times a day and for up to two minutes at a time. Since the tagamet he's down to just the occasional scratch and they last only a few seconds. I know the dose of tagamet he takes is much higher than others on the board but since our neurologist recommended it I'm comfortable with it. Good luck to you and I hope she feels better real soon.
