Remeron (mirtazapine) is a tetracyclic antidepressant. It affects chemicals in the brain that may become unbalanced and cause depression. It is thought to increase the activity of norepinephrine and serotonin which help elevate mood.
Remeron is used to treat major depressive disorder.
Remeron may also be used for other purposes not listed in this medication guide.
You should not take Remeron if you are allergic to mirtazapine or if you are also taking tryptophan (sometimes called L-tryptophan). Do not use Remeron if you have used an MAO inhibitor within the past 14 days. Serious, life-threatening side effects can occur if you take Remeron before the MAO inhibitor has cleared from your body.
You may have thoughts about suicide when you first start taking an antidepressant, especially if you are younger than 24 years old. Your doctor will need to check you at regular visits for at least the first 12 weeks of treatment.
