“Generic Prozac costs $4 at Wal-Mart, but it’s one of the drugs Obama wants to eliminate.”
Often it is only the time-release formula that is effective and the generic is frequently not yet available, as is the case with Seroquel XR.
Many of the generic drugs made by Sun and Intas are made only in the XR form, although they don’t have XR in the name. I don’t know about the two above, but it is the case with Effexor which I take.
