    What is the difference between ER and SR on a prescription>

    August 18, 2008

    I was taking Hyoscyamine ER .375 CAP(substituted for Levsinex), which really worked for me, and my Pharmacy said it was no longer available. They gave me Hyomax SR .375 TAB, which they say is the exactly the same thing, however my stomach says otherwise. I tried to find out the difference between ER & SR and cannot find an explanation. Is it just different becasue one is a Capsule and one is a Tablet. Does anyone know what other generic or brand name drug for Hyoscyamine is a capsule as well? 

     

    Thank you

    ER stands  for extended release; SR stands for sustained release - they seem to be referring to the same thing. You do hear from time to time about people responding  differently to generics or different forms of the drug but why? I don't know.

     

    According to RxList this drug also goes under the brand names Levbid, Levsinex, Spacol T/S, Symax Duotab, Symax-SR. Have you tried any of those?

    so Hyoscyamine and levbid are OFF the MARKET and cannot be purchased anymore.  According to my pharmacist the difference is the inactive ingredients, which he didn't have (CVS).  He said I would have to contact each manufacurer, get the list of active and inactive ingredients and compare to figure out why Hyomax is making me sick where Hyoscyamine was a wonder drug for me.  HOW FRUSTRATING!  If this is becuase of the FDA (from another post), who can I contact to complain (I'm sure everyone on this drug would agree!
