DESVENLAFAXINE SUSTAINED RELEASE - ORAL
COMMON BRAND NAME(S): Pristiq
WARNING: Antidepressant medications are used to treat a variety of conditions, including depression and other mental/mood disorders. These medications can help prevent suicidal thoughts/attempts and provide other important benefits. However, studies have shown that a small number of people (especially people younger than 25) who take antidepressants for any condition may experience worsening depression, other mental/mood symptoms, or suicidal thoughts/attempts. Therefore, it is very important to talk with the doctor about the risks and benefits of antidepressant medication (especially for people younger than 25), even if treatment is not for a mental/mood condition.
Tell the doctor immediately if you notice worsening depression/other psychiatric conditions, unusual behavior changes (including possible suicidal thoughts/attempts), or other mental/mood changes (including new/worsening anxiety, panic attacks, trouble sleeping, irritability, hostile/angry feelings, impulsive actions, severe restlessness, very rapid speech). Be especially watchful for these symptoms when a new antidepressant is started or when the dose is changed.
USES: Desvenlafaxine is an antidepressant (serotonin-norepinephrine reuptake inhibitor type-SNRI) used in the treatment of depression. It works by restoring the balance of natural substances (neurotransmitters such as serotonin and norepinephrine) in the brain. Desvenlafaxine may improve your mood, feelings of well-being, and energy level.
OTHER USES: This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.
Venlafaxine is very similar to desvenlafaxine. Venlafaxine has been used to treat anxiety and panic attacks.
HOW TO USE: Read the Medication Guide provided by your pharmacist before you start using desvenlafaxine and each time you get a refill. If you have any questions, consult your doctor or pharmacist.
Take this medication with or without food, usually once daily or as directed by your doctor. Dosage is based on your medical condition and response to treatment.
Do not crush, chew, or dissolve this medication in water. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.
To reduce your risk of side effects, your doctor may direct you to start taking this drug at a low dose and slowly increase your dose. Follow your doctor's instructions carefully. Do not take more or less medication or take it more frequently than prescribed. Your condition will not improve any faster, and your risk of side effects will increase. Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time each day.
It is important to continue taking this medication even if you feel well. Do not stop taking this medication without consulting your doctor. If you suddenly stop this drug, especially if it has been used for an extended time or in high doses, you may experience symptoms (withdrawal reactions) such as mood swings, headache, tiredness, sleep changes, and brief feelings similar to mild electric shock. To prevent these symptoms while you are stopping treatment with this drug, your doctor may reduce your dose slowly. Consult your doctor or pharmacist for more details, and report any withdrawal reactions immediately.
If you are switching from another antidepressant to desvenlafaxine, your doctor should slowly reduce the dose of your old antidepressant to prevent withdrawal reactions from the other antidepressant. Ask your doctor or pharmacist for more details.
It may take several weeks to feel the full benefit of this medication. Tell your doctor if your condition persists or worsens.
