Is anyone taking Topiramate? My doctor just prescribed it for

Is anyone taking Topiramate? My doctor just prescribed it for me because he said it’s the perfect combo for me because I have anxiety and I need to lose weight. He did mention that it’s not its primary use. But when I looked it up online, it said the FDA has not approved it for weight loss. It’s most for migraines, bipolar disorder. Now I’m not sure what to do.
