Remeron/Zisprin (generic name: mirtazapine) is a tetracyclic antidepressant (TeCA) that can be prescribed to address symptoms of Major Depressive Disorder (MDD).
This medication influences alpha 2 receptors in nerve cells, leading to the release of serotonin and norepinephrine neurotransmitters. Increased levels of these neurotransmitters aid in alleviating depression and related symptoms like sadness, low mood, loss of interest in activities and decreased appetite.
It can also be prescribed off-label for other behavior conditions such as panic disorder, post-traumatic stress disorder, obsessive-compulsive disorder, generalized anxiety disorder, and social anxiety disorder. Other symptoms for which it can be useful include insomnia, headaches, fibromyalgia and migraines.
Dosage
Doctors will prescribe the required dosage and dosing regime. Do not change the dose or stop taking the tablets without first consulting with the prescribing doctor or another qualified healthcare professional.
Remeron or Zisprin comes in varied strengths in tablet form. It can be taken with or without food. Since mirtazapine has a sedative effect, it is best to take it in the evening just before going to sleep.
