There are important pieces of information to know about Pristiq (Desvenlafaxine), including the following prescription facts:
- Pristiq (Desvenlafaxine) is often used for depression and mood disorders, but is also prescribed for anxiety disorders, such as attention deficit hyperactivity disorder, chronic neuropathic pain, and obsessive-compulsive disorder.
- If you notice improvements in your condition, you should not stop taking the medication before speaking with a physician.
- The normal dose of Pristiq (Desvenlafaxine) is 50 mg daily. Higher doses including amounts of up to 400 mg a day have been prescribed but are not common.

There are few regulations that apply to Pristiq (Desvenlafaxine). The drug is not listed on the DEA’s controlled substance list. Many people have argued, however, that this lack of regulation is responsible for some people misusing Pristiq (Desvenlafaxine). It is important to understand, however, that the medication can show up as false positives during substance use tests.
Desvenlafaxine is a synthetic SSRI containing venlafaxine. While venlafaxine is used in popular products like Effexor, desvenlafaxine is most commonly used in Pristiq.
Like other SSRIs, medical researchers are still trying to determine exactly how Pristiq (Desvenlafaxine) works. Most physicians, however, believe that medication works by blocking serotonin from being reabsorbed into a person’s brain. Preventing reabsorption in this manner is important because after the process occurs, serotonin stops being helpful at helping to control a person’s mood. It is important to note that it is yet to be definitively determined that this is how SSRIs work.
The approximate half-life of Pristiq (Desvenlafaxine) is 11 hours. This means that a person who takes 50 mg of the drug is expected to have 50% or 25 mg 11 hours after ingesting 50 mg. 11 hours after the drug was reduced to 50%, the remains of Pristiq (Desvenlafaxine) would be reduced to 12.5 mg. This division continues until traces of the drug in a person’s system are not noticeable. A drug’s half-life is slightly extended if a person is a long-term user of Pristiq (Desvenlafaxine), but after a week has elapsed the drug should become unrecognizable in a person’s system.
There are a variety of factors that determine how a person is affected by withdrawal from Pristiq (Desvenlafaxine) which include the following:
- Age. The length of time that it takes Pristiq (Desvenlafaxine) to be cleansed from a person’s system tends to increase among older individuals. Younger people are able to eliminate traces of the medication in their system much faster.
- Body Mass. The greater a person’s body mass, the quicker that they can excrete Pristiq (Desvenlafaxine) through their system.
- Dosage. People who take larger doses of Pristiq (Desvenlafaxine) can, sometimes, take longer to eliminate traces of the drug in their system versus people who take smaller doses.
It should be noted that there are many other physiology factors that influence the exact speed and manner in which a person’s body is cleansed from the medication.
Drug testing has become popular among companies in a variety of different industries. As a result, workers are often curious about how Pristiq (Desvenlafaxine) will remain in their system and how the drug might impact a drug test. Unfortunately, there are no exact answers to how long Pristiq (Desvenlafaxine) will remain in a person’s system. The only thing of which is sure is, if a person takes 10 mg of the medication, traces of the drug will not be in their system after a week.
