Antidepressant Discontinuation Syndromes: Common,
Under-Recognised and Not Always Benign
Antidepressants have varying potentials to cause
discontinuation syndromes. Symptoms begin within a few days of
stopping or reducing the dosage of the drug and are usually mild and
short-lived. However, in some patients, antidepressant
discontinuation symptoms can produce significant morbidity, be
incorrectly attributed to other causes, and lead to subsequent lack
of compliance with antidepressant therapy. The best approach to the
problem is prevention, which involves educating patients and
healthcare professionals about discontinuation symptoms and ensuring
that antidepressants are tapered before they are stopped. When
symptoms do occur, reassurance is usually sufficient; in some
patients, however, there may be a need for symptomatic treatment,
temporary reinstatement of the antidepressant (followed by careful
tapering), or a switch to fluoxetine (which has a low potential for
discontinuation symptoms). More research into this common and
clinically relevant syndrome is required so that evidence-based
recommendations can be developed.
