Suicidality and Antidepressant Drugs Antidepressants
increased the risk of suicidal thinking and behavior in children, teens, and young
adults. Depression and certain other psychiatric disorders are themselves associated
with increases in the risk of suicide. Patients of all ages who are started on antidepressant
therapy or when the dose is changed should be monitored appropriately and observed
closely for clinical worsening, suicidality, or unusual changes in behavior such
as becoming agitated, irritable, hostile, aggressive, impulsive, or restless. Should
these occur, report them to a doctor right away. PRISTIQ is not approved for use
in children under 18.
Do not take PRISTIQ if you are allergic to desvenlafaxine, venlafaxine, or any of
the ingredients in PRISTIQ. Do not take PRISTIQ if you currently take, or have taken
within the last 14 days, any medicine known as an MAOI (including intravenous methylene
blue or the antibiotic linezolid).
While the goal of taking PRISTIQ (desvenlafaxine) is to feel better, it’s important to know that
everyone responds differently to medication. And when it comes to antidepressants,
there are side effects. Many people shy away from—or stop taking—antidepressants
due to side effects. It can take time to find the right medication for you. You
and your doctor can determine if the benefits of treatment outweigh the burden of
side effects. Always discuss any side effects you are experiencing with your doctor.
What are the most common side effects of PRISTIQ?
In clinical studies, the most common side effects with PRISTIQ 50 mg were:
Nausea
Dizziness
Sweating
Constipation
Decreased appetite
These are not all the possible side effects of PRISTIQ 50 mg. For a complete list of side effects, please see Section 6 of the full Prescribing Information.
If you’re concerned about side effects, talk to your doctor.
How often do people stop treatment due to side effects?
It may be helpful to know that in clinical studies with PRISTIQ, people given PRISTIQ
and people given placebo (sugar pill) both reported experiencing side effects. A
small percentage (4.1%) of people stopped taking PRISTIQ 50 mg due to side effects;
a similar percentage (3.8%) of people given placebo also stopped due to side effects.
The most common side effects leading to discontinuation were nausea, dizziness, headache, and vomiting.
Will I gain weight with PRISTIQ?
While people react differently to PRISTIQ, in 8 and 12-week studies there was no clinical difference in weight gain between people
who took PRISTIQ 50 mg and those who took placebo (sugar pill). Longer term effect on weight has not been adequately studied.
Will PRISTIQ affect my sex drive?
While people react differently to PRISTIQ, in clinical studies there was a low occurrence
of sexual side effects in men and women taking PRISTIQ 50 mg, similar to those who
took placebo (sugar pill).
Sexual side effects include decreased sex drive, as well as delayed orgasm and ejaculation.
Side effects may increase with higher doses.
What if I want to stop taking PRISTIQ?
Stopping an antidepressant medicine, especially suddenly, can cause side effects called discontinuation symptoms. Your health care professional may want to reduce your dose slowly to help avoid these side effects. Some of these side effects may include:
