Antidepressants

• A small increase in the risk of suicidal thoughts at treatment initiation

• Explain toxicity in overdose.

• Explain that antidepressants take 2-4 weeks to work

• Aim to continue for at least 6 months after symptom cessation (to reduce relapse)

• If stopping antidepressants, wean down gradually over 4 weeks to reduce the risk of discontinuation symptoms (such as dizziness, nausea, paraesthesia, anxiety, diarrhoea, flu-like symptoms, and headache).

Choice of antidepressants

1st episode: SSRI sertraline, paroxetine

Recurrent episode: select an antidepressant that has previously elicited a good response
