Frequently asked questions

How long do antidepressants take to work?

Some effects appear in 1–2 weeks, but full benefit usually takes 4–6 weeks. Keep taking them and stay in touch with your doctor.

Can I stop antidepressants once I feel better?

Not suddenly — stopping should be gradual and doctor-guided, and treatment often continues a while after recovery to prevent relapse.
