Mirtazapine is a prescription medication used to treat depression (also known as major depressive disorder).
Mirtazapine is prescribed to treat depression (major depressive disorder) in adults.
It is commonly prescribed in conjunction with other forms of treatment like psychotherapy (“talk therapy”).
Mirtazapine is classified as an atypical antidepressant. It works by increasing levels of serotonin and norepinephrine in the brain. Serotonin and norepinephrine are neurotransmitters that help regulate mood.
Mirtazapine is available as an oral tablet and an orally disintegrating tablet.
The dosage and frequency of use depend on the condition being treated, its severity, and how you respond to the medication.
Follow your healthcare provider's instructions regarding dosage and schedule. Do not exceed the prescribed dose or frequency of use without consulting your provider.
