periactin (cyproheptadine) question: msg#00651

Subject: periactin (cyproheptadine) question
Periactin (cyproheptadine) did wonders for my guy's appetite  He's
been on it since the beginning of October.

However, it seems to be losing its effect.

Originally, what happened was, although the vet said 1/2 tablet, that
made him very hyper, and I went down to 1/16 tablet twice a day.  That
worked well.  When he occasionally had his weight drop, I'd give him
1/8 tablet once, which made him just slightly hyper and ravenous.

Even then, if I went to 1/8 tablet twice in a row, he'd get very
sleepy.  I am puzzled as to how this happens with the hyperness, but
there is it.

Lately, the 1/16 tablet is not enough to perk up his appetite, he just
either nibbles, or goes hours without any interest in food.  1/8
tablet once did almost nothing, and twice in a row made him sleep
almost all the time, he really coulld hardly keep his eyes open.

Anyone had this happen and have any suggestions?  I think I read
awhile ago that someone posted that Periactin had stopped working for
her cat and her vet said to discontinue it for awhile and then restart
it.  If that's the case, does it need to be tapered off to avoid
withdrawal symptoms, and how long does it need to be discontinued>

I left a message on Wednesday for the vet who prescribed it, but
haven't heard back from her.

Thanks a lot.
