Treatment in Pregnancy & Postpartum

    • Psychological intervention wherever possible
    • Drugs must be used with extreme caution in pregnancy and in those mothers who are breast feeding
    • The risk of prescribing to pregnant women must be weighed against the risk of not prescribing i.e. in some pregnant women it may be safer to prescribe
