What it does
Trintellix is used to treat major depressive disorder (MDD) in adults.
Common side effects
Nausea, Constipation, Vomiting
Key warnings
Antidepressants may increase the risk of suicidal thoughts and behaviors in young adults.
How It Works
Trintellix affects the levels of certain chemicals in the brain. These chemicals, like serotonin, help regulate mood. By changing the balance of these chemicals, Trintellix can help improve symptoms of depression.
How to Take It
Take Trintellix once a day by mouth, with or without food. The usual starting dose is 10 mg per day. Your doctor may increase your dose to 20 mg per day, or decrease it to 5 mg per day, depending on how you respond to the medicine. If you are taking 15 mg or 20 mg per day, talk to your doctor before stopping, as they may want you to lower the dose to 10mg for a week before stopping completely.
Pregnancy & Breastfeeding
Tell your doctor if you are pregnant or plan to become pregnant. Taking Trintellix in the last 3 months of pregnancy may cause problems in the newborn. There is a pregnancy registry to monitor outcomes in women exposed to antidepressants during pregnancy. You can register by calling 1-844-405-6185.
Missed Dose
If you miss a dose, take it as soon as you remember. If it is close to the time for your next dose, skip the missed dose and take your next dose at the regular time.
Storage
Store Trintellix at room temperature, between 59°F and 86°F.

Report counts do not establish causation — a FAERS entry documents a temporal association, not proof that the drug produced the outcome. Widely prescribed medications naturally accumulate more reports than niche therapies, so raw totals must be interpreted alongside total exposure. Shortage status, recall history, and patent information further shape supply and switching decisions.
