A drug or natural substance used to alleviate depression.
All antidepressants have side effects, but different people respond quite differently to the same antidepressant. Side effects such as insomnia, nausea, dizziness may go away after a few weeks, while others like sexual problems may not.
With drug based anti depressants you might start to feel better within 1 to 3 weeks of starting an antidepressant, but it can take 6 to 8 weeks to feel the full effect. One particular antidepressant may not work for you and you may need a different type you may need to talk to a doctor about trying a lower dose or switching to a different antidepressant.
Some antidepressants increase the amount of serotonin; a neurotransmitter or brain chemical. Combining these antidepressants with other medicines or illegal drugs that also increase serotonin can cause a serious reaction called serotonin syndrome or serotonin toxicity.
