Here, I think most people who take CTX do so orally. Some get IV but seems less common. If I were going to bother getting something in IV form I think I'd rather it be RTX, since that is the only way to get it and it is now preferred over CTX. But the CTX in oral form worked well for me, cleared up the worst of my Wegs issues, and I was able to get used to the side effects so they didn't bother me. It was easy, affordable, and dosages could be regulated any time.
