Quick question! I was taking 50 mg of topamax and I need to go up to 75, my psych told me that it doesn''t come in 75mg tablets, and told me to take one 50mg tablet and split half of another one. I got my prescription told and I asked the pharmacist if I could split them and she said yes, However, when I took my medicine today, I noticed that the 50mg tablet does not have a score mark, and I always thought that you could only split them if the pill has the score mark. I tried to splitting it anyway with a pill cutter but it came out kind of uneven. I was wondering if any of you guys split your pills like that and it's okay? Does the topamax still effective? Thanks!
