Common side effects of TRINTELLIX

You may experience side effects with TRINTELLIX. The most common side effects in short-term studies were nausea, constipation, and vomiting.

Nausea was mild or moderate, and its frequency was related to the dose. Nausea generally occurred in the first week, and became less frequent over time. Nausea may continue in some people. Generally, nausea lasted for about two weeks.

Suicidal Thoughts and Actions and Antidepressant Drugs

TRINTELLIX and some other antidepressant medications carry a Boxed Warning due to risk for suicidal thoughts and actions. Specifically, you should know:

  • TRINTELLIX and other antidepressants may increase suicidal thoughts and actions in some people 24 years of age and younger.
  • TRINTELLIX is not for use in children under 18.
  • Patients taking TRINTELLIX should call their doctor or get emergency help right away if they have new or sudden changes in mood, behavior, thoughts or feelings, or symptoms that are new, worse or worry them; or if they develop suicidal thoughts or actions.

So you're wondering about weight gain?

TRINTELLIX did not have significant impact on weight in short-term studies and during a 6-month phase of a long-term study of patients who responded to TRINTELLIX when compared to patients taking a sugar pill.

Some reports of weight gain have been received since product approval.

Can TRINTELLIX cause antidepressant sexual side effects?

As with other antidepressants, TRINTELLIX can be associated with sexual side effects during treatment. In 6- to 8-week clinical studies, up to 5% of Major Depressive Disorder (MDD) patients taking TRINTELLIX voluntarily reported sexual side effects. When proactively assessed in MDD patients with normal sexual functioning in seven studies using a self-rated questionnaire, reports of sexual side effects from doses of TRINTELLIX 5 mg, 10 mg, 20 mg were 16%, 20%, 29% in men (N=212) respectively and 22%, 23% and 34% in females (N=226) respectively, compared to placebo rates of 14% in males (N=162) and 20% in females (N=135).

Voluntary reports of sexual side effects with antidepressants are known to be underreported in part because patients may be reluctant to discuss them. A self-rated questionnaire designed to identify sexual side effects was used in TRINTELLIX clinical trials to determine how many people actually experienced sexual side effects with TRINTELLIX.

Can changing to TRINTELLIX from certain antidepressants help improve their sexual side effects? 

In an 8-week clinical study, patients whose depression improved on sertraline (ZOLOFT®), citalopram (CELEXA®), or paroxetine (PAXIL®) but who were experiencing sexual side effects from their treatment were switched to either TRINTELLIX or escitalopram (LEXAPRO®).

Results from this study showed:

  • Patients switched to TRINTELLIX showed greater improvement in antidepressant sexual side effects compared to those who switched to escitalopram (LEXAPRO®)*
  • Patients switched to TRINTELLIX or escitalopram (LEXAPRO®) also maintained improvement in depression from their previous antidepressant therapy

*Based on an average change from the overall score on a standardized sexual functioning questionnaire

Suicidal Thoughts & Actions

TRINTELLIX and other antidepressants may increase suicidal thoughts and actions in some people 24 years of age and younger, especially within the first few months of treatment or when the dose is changed. TRINTELLIX is not for use in children under 18. Depression or other mental illnesses are the most important causes of suicidal thoughts or actions. Pay close attention to any changes, especially new or sudden changes in mood, behavior, thoughts, or feelings. Call your doctor or get emergency help right away if you have symptoms such as suicidal thoughts or actions, impulsivity, aggressive or violent actions, depression, anxiety or panic attacks, agitation, restlessness, anger, irritability, trouble sleeping, an increase in activity or talking, or other unusual changes in behavior or mood; especially if they are new, worse, or worry you.

What should I tell my doctor before taking TRINTELLIX?

Before taking TRINTELLIX, tell your doctor:

  • about all your medical and other health conditions

Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements, since TRINTELLIX and some medicines may cause serious side effects (or may not work as well) when taken together. Especially tell your doctor if you take: medicines for migraine headache called triptans; tricyclic antidepressants; fentanyl; lithium; tramadol; tryptophan; buspirone; St. John’s Wort; medicines that can affect blood clotting such as aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), warfarin; and diuretics.

Call your doctor if you have eye pain, changes in your vision, or swelling or redness in or around the eye.
  • Low levels of salt (sodium) in your blood: Low sodium levels in your blood that may be serious and may cause death can happen during treatment with TRINTELLIX. Elderly people and people who take certain medicines may be at a greater risk for developing low sodium levels in your blood.
