Antidepressants Alongside Therapy: What the Evidence Shows

Where the combination outperforms

For severe depression, combination therapy shows better outcomes than either treatment alone in multiple randomised trials. For treatment-resistant depression, adding therapy to medication (or vice versa) is a standard next step. For depression with anxiety, combination often addresses both dimensions more effectively. For preventing relapse after recovery, therapy skills built during acute treatment continue helping after medication is stopped.

How they work together

The two treatments work through different mechanisms. Medication addresses biological aspects — restoring the neurochemical foundation for functioning. Therapy addresses psychological aspects — thought patterns, behavioural habits, relationship patterns, meaning-making. When both are addressed together, effects can be additive or synergistic. Some evidence suggests medication can make therapy more effective by improving the concentration and energy needed to engage.

Practical considerations

Access is often the limiting factor — GP-managed medication is more accessible than psychology in many parts of Australia. Cost matters — Medicare-rebated therapy through the MHTP covers up to 10 sessions per year, which may not be enough for some situations. Timing matters — starting both simultaneously versus one after the other has different clinical logic. Discuss what fits your situation with your GP.
