In reply to cont. Prozac after bad reaction WHAT FOR? & misc?, posted by Diane on November 7, 1999, at 12:20:51
There is the way most people respond to a medication, and the way each individual responds to a medication. The
two can be very different. There is a whole new branch of pharmacology emerging, "pharmacogenomics", because of
this. Some day there will be robust diagnotics utilized to predict who may have no response or a paradoxical
response to a drug. Until then, there's only trial and error. If your response doesn't make much sense to you,
don't worry, you're in good company. The best and the brightest have been scratching their heads for years over
just this issue. It is important to remember that because two things occur simultaneously does not necessarily
indicate causality. You might feel angry/hostile because the drug is making you feel sick, not because your
levels of serotonin have been boosted. The side effects may or may not be related to the drug's primary mechanism
of action.Reduced dose usually equals reduced efficacy, but not always. Some people need less of a drug to get a therapeutic
effect, and usually less of the drug means less severe side effects.The antidepressant response to elevated levels of monoamines (the mechanism of action of most antidepressants), is
complex. It is not entirely accurate to say one is antidepressed because they have boosted levels of serotonin.
Rather, changes in the level of serotonin in the synapse (in the case of Prozac, an increase due to inhibition of
reuptake) leads to changes in the pre and/or post-synaptic neurons that take time to develop. One is essentially
made LESS sensitive to serotonergic neurotransmission by Prozac. It is the induced changes in response that are
hypothesized to be the true markers of antidepressant effect, and it can take anywhere from a week to a couple months
before these changes are felt as an improvement in mood. It's safe to say that if you haven't responded after
six weeks or so, you should change doses or change medications.
