Pristiq (active ingredient: desvenlafaxine) is a prescription medication indicated for the following:

Major Depressive Disorder (MDD): Pristiq is used for the treatment of major depressive disorder, a condition characterized by persistent low mood, loss of interest or pleasure in activities, and other symptoms that interfere with daily life.
Generalized Anxiety Disorder (GAD): It is indicated for the treatment of generalized anxiety disorder, which involves excessive worry or anxiety that is difficult to control.

Pristiq belongs to a class of drugs known as serotonin-norepinephrine reuptake inhibitors (SNRIs), which work by increasing the levels of serotonin and norepinephrine, neurotransmitters in the brain that play a key role in regulating mood and anxiety levels.

Pristiq comes in tablet form and is taken orally with or without food as directed by a doctor, usually once a day. Do not crush, chew, or dissolve the tablets, as this can release all the drugs at once and increase the risk of side effects. Follow the doctor’s instructions carefully and do not increase the dose or use Pristiq more often or for longer than prescribed. Regular use of Pristiq is necessary to obtain the maximum benefit, and patients should take it at the same time each day to help them remember to take it.

The recommended dosage of Pristiq is 50 mg once daily, with or without food. The doses of 50-100 mg/day were shown to be effective, but there was no evidence that doses greater than 50 mg per day confer any additional benefit. Follow a doctor’s instructions carefully and do not increase the dose or use Pristiq more often or for longer than prescribed.
