If you are taking topiramate, just a warning. Make sure you get your medication from the same generic manufacturer every time you fill your prescription.
I have been on topiramate for about 6 months. I recently moved, and there are no Rite-Aids in my new area so I changed to CVS. Well, the CVS had a different generic supplier of topiramate. I had been getting one made by Camber, but this one was made by Glenmark Generics.
This very quickly became a big problem. At first I thought I was just feeling a placebo effect because I knew the pills were different. But within about 10 days it was obvious to me that there was a real problem going on. I was having all kinds of head pressure and light sensitivity issues, though thankfully no MAV reoccurrance. It felt very similar to when I was initially ramping up back when I was about at 75mg. I talked with a pharmacist and he said that the generics can differ in dosage from the brand name as much as 20%. So if the Camber is high by 20% and the Glenmark is low by 20%, the difference between the two could be as much as 40%!!! So switching from one to the other could be effectively like going from 120mg to 80mg overnight. I don’t think it was that dramatic–it felt more like I went from 100mg to about 80mg, but it still felt like something was wrong.
Calling around to several pharmacies in the area I was able to find one that carried the Camber generic. It cost me a fortune to chuck my half-used Glenmark pills and replace them with Camber pills out of pocket (insurance won’t cover them because they say I can’t get a new prescription for at least another week still) but at least I’m back on the medication that was helping me. I’m a bit bummed that something as small as changing the generic brand of topiramate set me off that much. Considering I was practically 100% I thought maybe I could even come off of the topiramate entirely, but obviously that isn’t the case at all, which is discouraging. But the main point I wanted to get out there to others is, make sure you are consistent with what generic form of topiramate you use, as going from one brand to another can mess you up. And don’t assume that just because you use one pharmacy all the time that they will always have the same generic brand. Some pharmacies change the kind that they use randomly. So check with your pharmacist and find out how they go about ordering their generics so that you know exactly what you will be getting before hand.
