In reply to F I N I S H = SRI Withdrawal Symptoms, posted by Sunnely on July 11, 2000, at 21:26:02
Thanks for this Sunnely - Are SRI's the same as SSRI's?? I'm taking an SSRI & this information is certainly important. Can't say that I'm looking forward to it if it applies to SSRI's. (Nobody mentioned this! I thought initial side effects were crummy enough. Oy well... :-(
I agree with Noa about the folder. It would be good to have a handy reference place for this.

> A MNEMONIC FOR SRI WITHDRAWAL SYMPTOMS (not all symptoms may be present):
>
> F = Flu-like symptoms (lethargy, fatigue, headache, achiness, sweating)
>
> I = Insomnia (with vivid dreams or nightmares)
>
> N = Nausea (sometimes vomiting)
>
> I = Imbalance (dizziness, vertigo, lightheadedness)
>
> S = Sensory disturbances ("burning," "tingling," "electric-like" or "shock-like" sensations)
>
> H = Hyperarousal (anxiety, irritability, agitation, aggression, mania, jerkiness)
>
> OTHER FEATURES:
>
> 1) Onset = Usually begin between 2 and 5 days after the last dose of medication; in some cases, even before the medicine is totally discontinued. (Note: Withdrawal symptoms from Effexor can occur even after missing a single dose.)
>
> 2) Withdrawal symptoms occur more quickly than recurrence of depression.
>
> 3) Duration = Withdrawal symptoms can last up to several weeks; typically mitigated by reintroducing the withdrawn antidepressant.
>
> 4) Cause = Unclear. Hypothesis: Patients on long-term serotonin-boosting antidepressants have "down-regulation" (decreased number) of postsynaptic serotonin receptors. When medication is stopped abruptly, less serotonin is present in a "down-regulated" state ----> withdrawal symptoms.
>
> 5) Most common with shorter acting antidepressants (practically all SRIs except Prozac; Effexor, most rapid and severe), those without active metabolites (daughter compounds), and when treatment has lasted at least a month.
>
> 6) May occur if a patient is switched from an antidepressant that boosts serotonin to one that does not have this action. For example: Paxil ----> Wellbutrin.
>
> 7) May be hard to separate from infectious causes. (No fever or elevated white cell count with SRI withdrawal, however.)
