I have been on diazepam recently and it didn't do anything for me. (Maybe due to the fact that I have been on Klonolpin aka Paxam aka Clonazepam for a number of years). Different countries have different names for for the same meds.

You could always google diazepam and fluoxetine to see what side affects are listed.
But you really wont know how it will affect you until you have tried it. Our bodies seem to process medications differently. What dosage a person can take will vary from person from person.

Hope this helped.
