More About Antidepressants:
What Is Pristiq?
Desvenlafaxine drug class is an SNRI antidepressant. Standing for serotonin and norepinephrine reuptake inhibitors, an SNRI medication increases feel-good chemicals in the brain by slowing the rate at which they are reabsorbed. Desvenlafaxine SNRI is considered to be safer than older generations of antidepressants, but how the body reacts to it varies between patients. Also known by its active ingredient, Desvenlafaxine, it has been FDA-approved for the treatment of major depressive disorder since 2008. While it has only one approved use, there are numerous off-label Desvenlafaxine uses such as for social anxiety disorders and panic attacks.
Is Desvenlafaxine A Controlled Substance?
Users may wonder if Desvenlafaxine is a controlled substance. The answer will depend on which definition of “controlled substance” is being used. The term is used by the Drug Enforcement Agency in an official capacity, referring to drugs that are on the DEA drug schedule. In this case, a controlled substance is one that has a high potential for abuse when weighted against its therapeutic applications and has special restrictions placed on it. The medication Desvenlafaxine is not considered to have a high abuse potential when compared to its benefits, and as a result, it is not a DEA controlled substance.
However, when the average person talks about controlled substances, what they typically mean is anything you need a prescription to access. Under this definition, Desvenlafaxine is a controlled substance.
Pristiq Generic And Brand Names
Pristiq is the original brand name of the drug Desvenlafaxine. It was created by Wyeth, which has since merged with Pfizer, the current manufacturer of the drug. It is currently the only manufacturer, though other versions of the medication are produced by other companies, such as Khedezla, made by Pernix Therapeutics.
Pristiq Generic Desvenlafaxine Succinate ER Versions Are Made by Numerous Pharmaceutical Companies, Including:
- Actavis Labs Fl
- Alembic Pharms Ltd
- Casi Pharms Inc
- Hikma
- Mylan
Pristiq generic versions have been available since 2015. It is important to note that while these formulations are all very similar to each other, there can be variations, especially when it comes to the inactive ingredients. This means side effects can vary depending on if the patient takes the brand names or a generic.
Pristiq Dosage Forms And Strengths
Take note that all drugs come with a unique, formulated design especially when a certain brand comes with different dosage strengths. Since Pristiq medication comes with three, all of these Pristiq dosage formulations have different designs.
| DOSE AND FORM | COLOR | SHAPE | IMPRINT |
| 100 mg tablet | Reddish-orange | Square pyramid | Debossed with “W” over “100” on the flat side |
| 50 mg tablet | Light pink | Square pyramid | Debossed with “W” over “50” on the flat side |
| 25 mg tablet | Tan | Square pyramid | Debossed with “W” over “25” on the flat side |
Desvenlafaxine is considered safe when it is used properly. The correct Pristiq dosage can vary between patients and conditions treated. Patients taking this drug should always abide by their doctor’s instructions to avoid dangerous side effects. When it is taken according to directions, it can help to alleviate symptoms of depression, address chronic pain, and prevent hot flashes.
What Is Pristiq Used For?
Although there are numerous Desvenlafaxine uses, there is only one FDA-approved application of the drug. This is the treatment of the major depressive disorder (MDD). It was the third-ever SNRI drug approved to treat depression.
Moreover, the one thing that is recommended is that Pristiq medication is taken at the same time each day. This ensures the amount of medication in the body remains more or less consistent, and there is less of a risk of accidental overdose. Additionally, for patients taking this drug, it is advised to never take it together with alcohol as this may lead to dangerous side effects.
Desvenlafaxine For Depression
According to numerous studies, the drug is highly effective in treating depression, even at lower doses. Because the SNRI class has fewer side effects and interactions than older antidepressant drugs, Desvenlafaxine is a fairly popular choice to use. However, that does not mean it is the right choice for all patients looking to treat their depression. Patients should examine all information on Desvenlafaxine use and contact a doctor before making a decision.
Desvenlafaxine For Anxiety
It is common for antidepressants to also be used in the treatment of generalized anxiety disorder and social anxiety. Limited studies have found that unlike some drugs in its class, anxiety treatment is not among the things Desvenlafaxine should be used for.
At best, it has been found to have roughly the same effect as a placebo when treating anxiety alone, though it can improve anxiety caused by depression. In some cases, it can actually increase the symptoms of anxiety disorders. As such, there is not considered to be a safe and effective Desvenlafaxine dosing for anxiety use at this time.
There isn’t a specific time of day when it is best to take Desvenlafaxine. The prescribing doctor can work with the patient to determine what time is best based on their habits, what is being treated, and when their symptoms tend to be the strongest.
Desvenlafaxine For OCD
Antidepressant drugs are frequently used to treat obsessive-compulsive disorder, also known as OCD. According to the study of medical doctors from Ohio, Desvenlafaxine’s effectiveness as a form of OCD treatment has yet to be studied. This means that its use might be effective at managing the condition, though there is also the possibility that it will have no impact or even make the disorder worse. If a patient’s doctor suggests the use of Desvenlafaxine for OCD treatment, they should ask about alternatives with a proven track record, such as for example Pristiq vs Effexor.
Desvenlafaxine For Menopause
While it is not among the Desvenlafaxine indications, the medication is used to treat some symptoms of menopause. It is considered to be an alternative to hormone therapy. Specifically, its use can reduce the occurrence of moderate to severe hot flashes and sleep disturbances associated with menopause. However, when compared with estrogen supplements, the effects are not nearly as strong, meaning that women who can have hormone therapy may be better off taking that route.
Pristiq Abuse And Addiction Overview
Medically speaking, physical Pristiq addiction is not possible. However, users can become psychologically dependent upon it, feeling as though life isn’t good enough without taking the medication. It is also possible to experience Pristiq withdrawal symptoms, especially if the medication is stopped suddenly or when it is taken with other substances such as alcohol. When this happens, considering resources such as rehab centers can help the patients have a safer recovery process.
According to a study of medical doctors from New York, Pristiq addiction and abuse is possible and this could lead to a fatal overdose. In the same study, it was reported that as of today, there are only two reported cases of Pristiq abuse. Further, these two cases will be elaborated on in this section.

Some Of The Physical ADR Include:

Patients may also consider other resources such as rehab centers for a safer recovery process.
Who Is Most At Risk Of Pristiq Abuse?
According to the study of medical doctors from Italy, patients with a history of alcohol and amineptine abuse are at risk of Pristiq abuse. Additionally, in this study, patients who administer the medication improperly make them become more prone to Pristiq abuse. In another study published in the New England Journal of Medicine, it was reported that patients with a history of major depression are also at risk of Pristiq abuse. Therefore, patients who are at risk of Pristiq abuse must contact or seek medical help in order to prevent dangerous health events.
Dangers Of Pristiq Addiction
Desvenlafaxine is a prescription medication that is used for the treatment of depression. This, being a prescription drug, means that only a doctor can tell the patient how to properly use the medication, in terms of the dose and frequency of use. Therefore, if a patient abuses and becomes addicted to this medication, there would be dangers to their health. According to the FDA, Pristiq addiction and abuse may cause Serotonin Syndrome and cardiovascular problems such as elevated blood pressure. If addiction is observed, immediately contact medical services in order to prevent other health dangers.
Recovering From Pristiq Addiction And Misuse

Moreover, this medication comes with off-label uses, and patients taking this drug must understand that this drug has abuse and addiction potential. Additionally, patients with alcohol abuse are more at risk of this addiction and this calls for considering resources for safer recovery.
If someone has abused the drug or is experiencing Pristiq addiction, help is needed. Drug rehab centers are possible resources that understand the unique aspects of antidepressant addiction and can help users end their dependence while still caring for their mental health.
