actually, SSRIs do appeare to addictive: i’ve had users tell me they’d like to stop taking them, but the physical neurological withdrawal symptoms were so unpleasant that they just keep taking them to avoid the withdrawal symptoms ...
This happens occasionally but it’s a very easy problem to solve. Those SSRIs with shorter half-lives are more likely to cause discontinuation symptoms. The solution is to substitute a longer half-life SSRI to get the patient off the shorter half-life drug. Prozac’s half life is in the range of 36 -48 hours. If your friends are having trouble discontinuing their SSRIs, tell them to see their doctor and have him/her prescribe two weeks worth of Prozac then stop it. The Prozac will taper itself out of the system more slowly due to its extended half life. They won’t have any discontinuation symptoms.
