Pristiq (desvenlafaxine) is an antidepressant approved by the Food & Drug Administration (FDA) to treat major depressive disorder (MDD) in adults 18 and older. Many antidepressants are covered by insurance companies, but not all do so when generic versions are available. Here’s what to know about generic Pristiq, how it compares to the brand-name version, and how to save.
Is there a generic for Pristiq?
Yes, the generic for Pristiq is desvenlafaxine, which is the active ingredient in Pristiq. The generic was approved for use by the FDA in 2008.
Is desvenlafaxine the same as Pristiq?
In terms of active ingredients, desvenlafaxine and Pristiq are identical, per Erika Gray, Pharm.D., cofounder of Toolbox Genomics. In fact, it’s an FDA requirement, she adds, that the manufacturer of any generic drug prove their product is biologically the same as the brand-name version.
However, there may still be differences between generic desvenlafaxine and Pristiq. Generic medications may differ in size or color from brand-name versions and may contain different inactive ingredients, such as fillers and dyes, which may affect a person’s response to the drug.
“As a pharmacist, I regularly have people tell me that the generic medication does not work as well as the brand medication despite [them] having identical active ingredients,” Dr. Gray says. “From my experience, I have found that some people are more sensitive to the differences in the inactive ingredients, which leads them to believe the generic medication is less effective.”
Finally, generic medications are almost always cheaper than brand-name medications (though there are some exceptions). This means they are often categorized as preferred drugs by insurance companies, which would rather cover a cheaper drug than a more expensive one when the active ingredients are identical, and the medications have the same effects on consumers.
Pristiq vs. desvenlafaxine side effects
Unless you are sensitive to one of the inactive ingredients in desvenlafaxine or Pristiq, you can expect the side effects to be the same between both drugs.
Common side effects of Pristiq and desvenlafaxine include:
- Nausea
- Dizziness
- Sleep disturbances
- Sweating
- Constipation
- Drowsiness or fatigue
- Loss of appetite
- Anxiety
- Sexual dysfunction
Rare but serious side effects include:
- Angle‑closure glaucoma
- Hyponatremia (low sodium in the bloodstream)
- Worsening depression or mania
- Suicidal thoughts or behaviors
- Seizures
- Blood pressure changes
- Severe allergic reaction
According to Zishan Khan, MD, psychiatrist and regional medical director with Mindpath Health, it’s important to know these serious side effects are a possibility, but keep in mind they occur more often in people with specific, known risk factors. For example, you have a higher risk of developing angle‑closure glaucoma if you have a personal or family history of glaucoma, he explains. Desvenlafaxine is usually tolerated well, but some people are more prone to side effects, including:
- People who are sensitive to serotonergic or noradrenergic medications in general
- People taking higher doses
- Older adults, who are more vulnerable to blood pressure changes, falls, and electrolyte disturbances
- People with pre‑existing hypertension or cardiovascular disease
- People taking multiple serotonergic medications (because of the risk of serotonin syndrome)
- People with bipolar spectrum illness, who are more prone to mood switching into hypomania or mania
Finally, it’s important to note that Pristiq and desvenlafaxine include the same boxed warning (sometimes called a “black box warning”) as all other antidepressants regarding a potential risk for suicidal thoughts and behaviors. Dr. Khan notes some things to remember:
- The warning does not mean Pristiq “causes suicide,” but that in younger people there is a statistically increased rate of suicidal thinking and behavior compared with placebo in short‑term trials.
- The highest risk windows are the first few weeks of treatment and around dose changes, when energy may improve before mood and hopelessness fully lift.
- Families and patients should watch for new or worsening suicidal thoughts, agitation, irritability, or extreme behavioral changes, and contact their prescriber immediately if these emerge.
- For many patients, especially adults, the overall effect of effective antidepressant treatment is a reduction in suicidal risk over time, but early vigilance is crucial.
Pristiq vs. desvenlafaxine cost and coverage
Generic desvenlafaxine costs less than brand-name Pristiq. The average retail price of a 30-day supply of 100 milligram (mg) extended-release Pristiq tablets is around $543. In comparison, generic desvenlafaxine costs around $333 for the same supply and dose.
“Insurance companies prefer the generic option…because of the significant cost savings [to them],” Dr. Gray says. “In fact, they will often place brand-name Pristiq in a ‘higher tier,’ which may mean limited coverage, a higher copay, or the requirement of a prior authorization form.”
Is there a cheaper alternative to Pristiq?
If you can’t afford Pristiq or desvenlafaxine, there are several alternatives you may be able to take instead. You should always discuss this with your healthcare provider; they are the best person to help you choose a similarly effective drug that fits into your budget.
According to Dr. Khan, some of the more common alternatives to Pristiq include other SNRIs like venlafaxine ER (Effexor XR), duloxetine, and Fetzima. These are usually the closest pharmacologic substitutes, he explains, since they work similarly to one another and are widely prescribed for major depression and anxiety. Venlafaxine ER, in fact, is the active metabolite, or parent drug, of desvenlafaxine. When your body breaks down venlafaxine, it turns the drug into desvenlafaxine.
“[Venlafaxine XR] is chemically very similar, works well, and is often the most common substitute for desvenlafaxine,” Dr. Gray says.

It may also be an option to take a different class of antidepressants, per Dr. Khan, including SSRIs and atypical antidepressants. See the tables below for more information on how the costs of brand-name Pristiq and generic desvenlafaxine compare to popular alternatives.

The listed price without insurance references the price of brand-name drugs (unless otherwise specified). The listed SingleCare price references the price of generic drugs if available.
“From a cost and access standpoint, venlafaxine XR and duloxetine are often the closest substitutes to Pristiq because they are in the same SNRI class and widely available in generic form,” Dr. Khan says. “Many patients who respond well to Pristiq will also respond to one of these, though switching should always be done under medical supervision.”
