Venlor 150 mg: Everything You Need to Know
Venlor 150 mg is a prescription antidepressant that contains Venlafaxine (SNRI), used primarily to treat Major depressive disorder and several anxiety-related disorders.
Venlafaxine works by increasing the levels of serotonin and norepinephrine in the brain—two neurotransmitters involved in mood regulation, emotional stability, and stress response. Because it affects brain chemistry, it should always be used under medical supervision.

Venlor contains venlafaxine, an antidepressant belonging to the SNRI class.
The 150 mg dose is considered a moderate to higher therapeutic dose and is often used when lower doses are not sufficient to manage symptoms effectively.
