Can Use Of Famotidine Cause Increase In Blood Glucose Levels?

Can my use of famotadine cause increase in nlood glucose levels? Type II diabetic with three years of a1c levels being no greater than 6 - on antihypertensives andimdur for vasodilation but have been steady on thee for years. The only new factors in the equation have been the addition of pepcid and occasional .5 mg of alprazolam at bedtime due to some spinal stenosis causing new pain. I'm 67, good energy, brain at least mimics its previously good intellectual function. Concerned - ate bowl of plain oatmeal and slice of cantaloup at 11 am, nothing since, just tested with out-of-date strips and was 287!!!!! Testing a rare occasion, have gone by a1c levels. Help??? (and I have a couple of good physicians but it's 6 pm on Sunday...
