Question about Zantac75?

Ok, i am not new to GERD but i am new to having to take Zantac on a daily basis.. at least lately anyways.. was just wondering if anyone knew if there were any long term effect of taking it on a daily basis. As well as i take Tegretol 400mg 2x a day to control non epileptic seizures. One website i went to had a comparison of zantac and taking prescription drugs and one of the drugs it was compated to was Depakote, now thats not tegretol but still.... and it said that theres a possiblilty of alteration in seizure control. I have been on Tegretol for about 6-7 yrs now. and have been completely seizure free for almost 4 yrs... so i was wondering if anyone had any info about this and taking them both daily... or if there were any known long term affects of Zantac... Yes i know we are not medically licensed (blah blah blah lol) but an opinion would be great! Thanks!
