What is Viibryd?
Viibryd (vilazodone) is an antidepressant in a group of drugs called selective serotonin reuptake inhibitors (SSRIs).
Viibryd is used to treat major depressive disorder (MDD).
Viibryd may also be used for purposes not listed in this medication guide.
Do not use Viibryd if you have used an MAO inhibitor in the past 14 days, such as isocarboxazid, linezolid, phenelzine, tranylcypromine, and others, or if you have had a methylene blue injection. A dangerous drug interaction could occur.
Some young people (children and adults ages 24 and younger) have thoughts about suicide when first taking an antidepressant. Stay alert to changes in your mood or symptoms. Report any new or worsening symptoms to your doctor.
Viibryd is not approved for use in children.
Before taking this medicine
Some medicines can interact with vilazodone and cause a serious condition called serotonin syndrome. Be sure your doctor knows about all other medicines you use, especially other anti-depressant, anti-anxiety, ADHD, or migraine medications. Ask your doctor before making any changes in how or when you take your medications.
To make sure Viibryd is safe for you, tell your doctor if you have:
liver or kidney disease;
a bleeding or blood clotting disorder;
seizures or epilepsy;
bipolar disorder (manic depression);
a history of drug abuse or suicidal thoughts;
if you drink alcohol; or
if you have been diagnosed with low sodium in your blood.
Some young people have thoughts about suicide when first taking an antidepressant. Your doctor should check your progress at regular visits. Your family or other caregivers should also be alert to changes in your mood or symptoms.
Taking an SSRI antidepressant during the third trimester of pregnancy may cause serious lung problems or other complications in the baby. However, you may have a relapse of depression if you stop taking your antidepressant. Tell your doctor right away if you become pregnant. Do not start or stop taking this medicine during pregnancy without your doctor's advice.
If you are pregnant, your name may be listed on a pregnancy registry to track the effects of vilazodone on the baby.
It is not known whether Viibryd passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
Do not give Viibryd to anyone under 18 years old without medical advice. Viibryd is not approved for use in children.
