The clinical problem of whether to stop antidepressants when patients
develop mania is looked at in the light of existing practice and advic
e both in the UK and in the USA. It is concluded that practice is base
d more on an empirical than a scientific basis. The literature on the
subject is reviewed with especial reference to the questions of whethe
r antidepressants actually cause mania, whether they interfere with th
e treatment of mania, whether discontinuing them stops mania and wheth
er withdrawal of antidepressants causes mania. Finally a case notes st
udy conducted by one of the authors is summarized and recommendations
for further research are made.
