A family member was prescribed Levsin for chronic GI pain. I was informed that the drug referred to as Levsin was not manufactored anymore. I received the brand name Hyomax SL because the generic Hyoscyamine was no longer available.
Please respond: Is Levsin still available? What is the difference in Levsin and Hyomax? Is the generic Hyoscyamine still available?
There doesn't appear to be a simple answer to your question. Although Levsin and hyoscyamine are still listed in most drug guides, they don't seem to have been available for a couple of years now.
The best explanation I've found was in response to another question we had about Levsin/Hyoscyamine/Hyomax. Here's a link to it: Levsin/Hyoscyamine/Hyomax The second answer by an RN named Brenda explains why hyoscyamine is not available. If you'll read through all the answers, you'll find other interesting information as well.
When I checked the FDA's site, I found that none of the three have FDA approval, so I'm not sure why Hyomax is available and the others aren't. Perhaps your pharmacist can tell you more about that.
