Introduction

Antidepressants can cause unpleasant side effects. Signs and symptoms such as nausea, weight gain or sleep problems can be common initially. For many people, these improve within weeks of starting an antidepressant. In some cases, however, antidepressants cause side effects that don't go away.

Talk to your doctor or mental health professional about any side effects you're having. For some antidepressants, monitoring blood levels may help determine the range of effectiveness and to what extent dosage can be adjusted to help reduce side effects. Rarely, antidepressants can cause serious side effects that need to be treated right away.

If side effects seem intolerable, you may be tempted to stop taking an antidepressant or to reduce your dose on your own. Don't do it. Your symptoms may return, and stopping your antidepressant suddenly may cause withdrawal-like symptoms. Talk with your doctor to help identify the best options for your specific needs.
