Mirtazapine is an antidepressant. The way this medication works is still not fully understood. It is thought to positively affect communication between nerve cells in the central nervous system and/or restore chemical balance in the brain.
Mirtazapine is used to treat major depressive disorder.
Mirtazapine may also be used for purposes not listed in this medication guide.
Mirtazapine is the generic form of the brand-name antidepressant Remeron, which is used to treat depression and other ailments.
In some patients, depression may be associated with abnormal levels of neurotransmitters, the brain chemicals that nerve cells use to communicate with each other.
Remeron (mirtazapine), which belongs to a class of drugs known as tetracyclic antidepressants, can treat depression by moderating the levels of neurotransmitters in the brain.
Antidepressants such as mirtazapine are also prescribed “off-label” to treat other conditions, such as post-traumatic stress disorder (PTSD), obsessive-compulsive disorder(OCD), and other anxiety disorders.
The drug has also been prescribed as an appetite stimulant. (One of its most common side effects is weight gain.)
Mirtazapine was approved by the Food and Drug Administration (FDA) for use as an antidepressant in 1996. Its patent expired in 2004 and generic versions are now available.
