Q: What is Pristiq used for?

Pristiq is used to treat major depressive disorder .

Q: How does Pristiq work?

Mechanism of Action Pristiq belongs to a class of medications called serotonin-norepinephrine reuptake inhibitors (SNRIs). It works by affecting the balance of two natural chemicals in the brain called serotonin and norepinephrine. These chemicals are neurotransmitters, which act as messengers between nerve cells. They are known to play a significant role in regulating mood, emotions, and mental health. In many people with depression, these chemicals may not be functioning correctly or may be in short supply. Pristiq works by: Blocking reuptake: After serotonin and norepinephrine are released by a nerve cell, they are normally reabsorbed by that same cell. Pristiq blocks this reabsorption process. Increasing availability: By preventing reabsorption, the medication allows more of these chemicals to remain in the space between nerve cells (the synapse). Improving communication: With more serotonin and norepinephrine available, communication between nerve cells is enhanced, which helps to stabilize mood and relieve symptoms of depression.

It can be taken with or without food. Consistency For the best results, take this medication at the same time every day. You may notice the empty shell of the tablet in your stool; this is normal and does not mean the medication was not absorbed. Missed Dose If you miss a dose, take it as soon as you remember. If it is almost time for your next scheduled dose, skip the missed dose and continue with your regular schedule. Do not take two doses at the same time to make up for a missed one.

Q: Is Pristiq safe during pregnancy and breastfeeding?

Pregnancy The use of Pristiq during pregnancy requires a careful discussion with a healthcare provider to weigh the benefits of treatment against potential risks to the fetus. If you are pregnant or planning to become pregnant, consult your doctor before starting or stopping this medication. Research indicates that infants exposed to SNRIs like Pristiq during the third trimester may experience complications at birth that require hospitalization, respiratory support, or tube feeding. Reported symptoms in newborns include: Breathing problems Seizures Tremors or jitteriness Feeding difficulties Low blood sugar Muscle stiffness or limpness Constant crying There is also a potential risk of persistent pulmonary hypertension of the newborn (PPHN), a serious lung condition. However, untreated depression during pregnancy also carries risks for both the parent and the baby. Healthcare providers may suggest enrolling in a pregnancy registry to monitor the health of those taking antidepressants while pregnant. Breastfeeding Pristiq passes into breast milk. Because the effects on a nursing infant are not fully known, it is important to discuss breastfeeding with a healthcare provider. They can help determine if the benefits of breastfeeding outweigh the potential risks of the infant being exposed to the medication.

Q: What forms and strengths does Pristiq come in?

Pristiq is supplied as an extended-release tablet for oral use. This medication is designed to be swallowed whole. The tablets should not be crushed, chewed, dissolved, or divided, as these actions can interfere with the controlled release of the medicine into the body.

Q: What is the FDA approval status of Pristiq?

It is a serotonin and norepinephrine reuptake inhibitor (SNRI) that was first approved for use in 2008. Boxed Warning The FDA has issued its most serious safety notification, a boxed warning, for Pristiq. This warning highlights that antidepressants may increase the risk of suicidal thinking and behavior in children, adolescents, and young adults up to age 24. Healthcare providers are advised to monitor patients of all ages closely for clinical worsening or the emergence of suicidal tendencies, especially during the initial months of treatment or following dosage adjustments. Usage Restrictions Pristiq is not FDA-approved for use in pediatric patients. The safety and effectiveness of the medication in children and adolescents have not been established. Additionally, while it is not a controlled substance, it must be dispensed with a Medication Guide that informs patients of potential risks.
