My daughter is 31 and too was taking topamax when she had her VP shunt. Got that revised abt 1 1/2 yrs to a VA shunt. I myself weaned her off the topamax because it didn't do any good anyway. Talk to your doc abt that. Took her to the ER 4 days ago. Had a ct scan done cause of sharp pains, gagging, eyes not focused but shunt is working good. They recommended I get another neurosurgeon to follow up ev other month. She had a UTI (which she has had since birth but flares up 1x a yr), gave her antibiotics, Hydrocodone for pain in her head. I don't know what other disabilities he has but my daughter has no bowel or bladder control. I give her Immodium to not have "accidents" and if she doesn't go for a cpl of days it gives her headaches too. Gonna try another way to regulate her. Good luck. We learn after yrs of this to do our own remedies sometimes at home. Cause what works for one might not work for another. Docs and neurosurgeons have a standard way of doing things. We learn to work around that to make our kids comfortable.
