I just added 10 mgs of Prozac to my Serzone. I dropped from 500 to 400 when I started the Prozac. It has helped incredibly with the sedation thing, AND it seems to have lifted that last bit of fog that I couldn't shake.
Does anyone know of successes/interactions for this combo?

> Modafinil (Provigil), a central nervous system stimulant which is FDA-approved for narcolepsy, induces the cytochrome P450 enzyme 3A4 (CYP3A4). Nefazodone (Serzone) is mainly dependent on this enzyme for its metabolism. The combination of Provigil and Serzone could lead to increased metabolism of Serzone (rapid formation of daughter compounds) ---- > decreased in Serzone blood level ---- > loss of Serzone effectiveness. Incidentally, one of Serzone's daughter compounds called mCPP (meta-chlorophenylpiperazine) is known to induce anxiety (anxiogenic). Theoretically, the rapid formation of mCPP could lead to anxiety and, this could become even more problematic if you belong to the 7-10% of Caucasian population who are genetically deficient of the cytochrome P450 enzyme that mainly metabolizes mCPP, CYP2D6. Provigil, being a psychostimulant itself, could further complicate this problem (i.e., anxiety, activation, insomnia).
