Stella Marie ~ I've been on dilantin for 28 years, I have/had "neuorpathy" for several years now, in my feet and toes (tingling,pins & needles,numbness).
I recently mentioned this to my neurologist, he said that it WAS a side effect of dilantin long term use.
Burnt_Orange_2 ~ Dilantin does seem to lose some of its effectiveness but really, b/c of the long term use, keep in mind that over several years, your body chemestry changes and weight losses/gains, diet changes, AGE GAIN (that seems to be the biggest factor) etc can effect the effectiveness of the dilantin. Your Doctor should be informed of this so he can adjust your doseage.
