Side effects

There’s stigma around taking medication for depression. However, recently-developed antidepressants don’t have the severe side effects they had years ago. They won’t alter your mood or make you feel high. They aren’t tranquilisers and don’t cause addiction.

How you feel when you stop taking antidepressants

It’s difficult to know how you might feel when you stop taking antidepressants.

Antidepressants don’t cure depression or anxiety, they ease the symptoms.

For some people, when they stop taking antidepressants their mood gradually worsens and they need to take medication for longer. For others, the feelings of depression or anxiety will have passed and they continue to feel better.

How you feel will depend on things like what’s caused your depression or anxiety and whether other treatments have helped.

How to stop taking antidepressants

You shouldn’t suddenly stop taking antidepressants. They can cause withdrawal symptoms, including:
