Serotonin syndrome is a rare but serious side effect
Pristiq (desvenlafaxine) is a prescription drug used to treat major depressive disorder in adults. While Pristiq can cause mild to serious side effects, these are usually rare. Serious side effects that have been reported with Pristiq include serotonin syndrome, a rare but dangerous condition caused by a buildup of serotonin in the body.
Serotonin syndrome occurs when there is too much serotonin in the brain. This can be caused by taking Pristiq with other medications that increase serotonin levels. Certain medications that increase serotonin include buspirone (Buspar®), fentanyl (Abstral®, Duragesic®), lithium (Eskalith®, Lithobid®), tryptophan, and St. John's wort. It is important to share an up-to-date medication list with your prescriber and pharmacist before starting Pristiq to identify potential drug interactions.
The symptoms of serotonin syndrome can vary and may include a fast heart rate, sweating, muscle stiffness, spasms, fever, and seizures. It is important to seek medical attention immediately if you think you are experiencing serotonin syndrome, as it can be life-threatening. Additionally, stopping or lowering your dose of Pristiq suddenly can lead to withdrawal symptoms, so it is important to consult your healthcare provider before making any changes to your medication.
While muscle pain is a reported side effect of Pristiq, it is not specifically listed as a symptom of serotonin syndrome. However, muscle soreness and stiffness have been anecdotally reported by some individuals taking Pristiq. It is always important to consult your healthcare provider if you experience any concerning side effects, as they can provide guidance and recommendations specific to your situation.

Pristiq may cause sexual side effects and ED
Pristiq (desvenlafaxine) is a selective serotonin and norepinephrine reuptake inhibitor (SNRI) that is used to treat major depressive disorder (MDD) in adults. While it has been shown to have a low potential for causing sexual dysfunction, there are still some risks and side effects associated with its use that patients should be aware of.
Sexual dysfunction is a common concern for patients treated with antidepressants, and Pristiq is no exception. However, clinical studies have shown that the rates of sexual dysfunction among patients taking Pristiq are comparable to those taking a placebo. Specifically, in a phase 4 study, patients taking Pristiq 50 mg/day or 100 mg/day showed similar rates of sexual dysfunction to those taking a placebo at both baseline and week 8.
Despite these reassuring findings, it is important to recognize that sexual side effects can still occur in some individuals taking Pristiq. These side effects can include problems such as decreased libido, erectile dysfunction, and anorgasmia. While these issues may resolve on their own as the body adjusts to the medication, they can sometimes persist or become more severe.
If you are experiencing sexual side effects while taking Pristiq, it is important to consult your healthcare provider. They may recommend adjusting your dosage or trying a different antidepressant. Do not stop taking Pristiq or lower your dose without first speaking to your doctor, as this can lead to uncomfortable withdrawal symptoms.
In addition to sexual side effects, Pristiq may also cause other side effects such as insomnia or drowsiness, nausea, increased sweating, dry mouth, decreased appetite, and muscle pain. More serious side effects may include serotonin syndrome, suicidal thoughts or behaviors, and high blood pressure. It is important to be aware of these potential side effects and to seek medical advice if you experience any concerning symptoms.
