NHS Talking Therapies - Self-referral route for anxiety and depression in England.
Mind - UK charity guides to conditions, treatments and legal rights.
Samaritans - Free 24-hour listening support on 116 123.

Report an error or outdated claim.

Antidepressants, anti-anxiety medicines and mood stabilisers are prescribed by a GP or psychiatrist after assessment. Trials show antidepressants help more people than placebo in moderate to severe depression, with smaller or uncertain benefit in mild depression. Effects usually take weeks, and side effects often appear first.

Things worth understanding

Medication and talking therapy are often used together, not as rivals.
Stopping suddenly can cause discontinuation symptoms; changes are planned with the prescriber.
Side effects vary by medicine and by person and should be reported, not endured in silence.
Websites that sell or recommend specific medicines without assessment are not a safe route.

This lesson explains how these medicines are studied. It does not recommend any medicine or dose; those decisions belong with a prescriber who knows your history.

If you or someone else cannot stay safe, call 999. Samaritans: 116 123, free, 24 hours.
