I took Dilantin for about 15 years. After that I was told if taken for 10 years I would get Osteoporosis. And I did. I had to take vitamin D3 pills every day for 2 years before I was okay again.

I have taken Dilantin since I was 7 ... never stopped me! but I do now have osteoarthritis, and peripheral neuopathy.

Yes, i have taken Dilantin and i did have the experience. But it seems like Dilantin isn't the only drug that can give you that experience. A lot of factors are involved such as how your type of seizures affects you and your body. And how does the medication treat you.
