Is mirtazapine a strong antidepressant?

Mirtazapine is considered to be a moderately strong antidepressant medication. It is a type of antidepressant known as a noradrenergic and specific serotonergic antidepressant (NaSSA) that works by increasing the levels of certain neurotransmitters in the brain, such as norepinephrine and serotonin.

Mirtazapine is often prescribed for the treatment of major depressive disorder and has been found to be effective in reducing symptoms of depression in many patients. However, like all antidepressant medications, its effectiveness can vary from person to person and it may take several weeks for its full therapeutic effects to be felt.

It is important to note that mirtazapine can also have side effects, including drowsiness, weight gain, and increased appetite. It is important to discuss any questions or concerns you have about mirtazapine or any other medication with a qualified healthcare provider.


There are various forms of drugs available, such as tablets or liquids, and each may have a separate patient information leaflet (PIL) for different doses. It is important to refer to the PIL for the specific form and dose of the drug that you have been prescribed.
