Split Dose Imatinib

Dear all,

I hope the following will be of interest to others in a similar position, but forgive the content, not everyone's cup of tea!

I have been on 600 mg of Imatinib since October 2005, and the problem side effect for me is Diarrhoea, sometimes explosive. I have to go to the toilet at least twice a day, and this is a minimum. Watching the diet is imperative, or I really pay for it. I suffered on 400 mg, and it got worse on 600 mg. I have discussed diet etc. with Consultants over time, but always felt that I would have to get on with it. Anyway, a small price to pay for otherwise good health but it does get me down.

I discussed it again at the Hammersmith on the 6th. Feb, and was advised to split dose to 300 mg morning & evening, or 400 mg & 200 mg. and see if things improve. Well 12 days on and I have seen a marked improvement. Early days, but encouraging. I also wonder whether less toilet visits will mean that Imatinib is in my system longer and therefore I may achieve a lower PCR? Hope so, as I seem to have reached my level of not quite a 2 log reduction.

No doubt others in a similar position will discuss dose splitting with their Consultant before trying it.

Best Wishes,

Phil.

my son started on 300mg and having never taken any regular medication struggled to cope with the tablets and nausea so we split his dose to 150mg after breakfast and 150mg after supper, this seems to suit him better but interesting to hear about your toilet habits as if he needs the toilet he needs to go straight away. Having taken 300mg for a year he increased to 400mg which again we split and he is now in remission having got a 3 log reduction

Hi Phil,
thanks for letting us know about the effects of splitting your dose. i am sure this will help others with this quite debilitating side effect. i do hope that this strategy continues to work and yes... i agree that it might have the effect of keeping your plasma levels higher with the knock-on effect of a lower pcr ;o) finger crossed.
best wishes,
Sandy ;o)

Thank god im not the only one with this problem,i go to the toilet at least 5 times aday(nice),and when you gotta go you really do need to go there and then.I take the 600mg altogether so i will think about splitting it.
take care,kathy

DX April 2007. After a few weeks of misery, I split my 400mg dose morning and evening after food and it helped a lot. Up to now, it has seemed to be working OK.
