The Food and Drug Administration (FDA) have approved Trintellix to treat major depressive disorder (MDD), or depression.

Trintellix works differently to standard antidepressants. It belongs to a class that doctors call atypical, miscellaneous, or multimodal antidepressants. Whereas other antidepressants affect one mechanism within the brain, Trintellix works in several ways in the brain.

Researchers are not sure exactly how Trintellix works. They believe it may block the brain’s reuptake of the neurotransmitter serotonin, which is a hormone involved in mood and motivation. However, it works differently to selective serotonin reuptake inhibitors (SSRIs).

There is currently no generic version of Trintellix available.

Like other antidepressants, Trintellix has some potential side effects and warnings.


Uses

Doctors prescribe Trintellix primarily to treat depression, a mental health condition that causes persistent feelings of sadness, feelings of hopelessness, and a loss of interest in usual activities.

Some doctors may prescribe Trintellix off label to treat other conditions. Off label use means that doctors prescribe a particular drug to treat a condition that was not the manufacturer’s intended use for the drug. Some additional uses for Trintellix include:

How to take Trintellix

Trintellix is available in immediate-release tablet form in the following dosages:

  • 5 milligrams (mg)
  • 10 mg
  • 15 mg
  • 20 mg

The package insert for Trintellix recommends that a person starts treatment at 10 mg and moves up to 20 mg after a few weeks. A doctor may prescribe a 5 mg dose to people who cannot tolerate higher doses well.

A doctor will determine the appropriate dose based on:

  • age
  • current medications
  • medical conditions
  • the severity of the condition

People should take Trintellix at the same time each day and avoid missing a dose. They can take the medication with or without food.

Like most antidepressants, it will take a few weeks before a person starts to notice any effects from taking Trintellix.

People can stop taking Trintellix abruptly, but a person should speak with their healthcare provider before stopping taking the drug. However, stopping abruptly when taking higher doses can cause:


Moderate side effects

Common side effects of Trintellix include nausea, constipation, and vomiting.

Like all drugs, Trintellix can cause side effects that range from mild to severe. Some people do not experience adverse side effects.

The most common side effects of Trintellix, which occur in at least 5% of people who take the drug, are:

Mild to moderate side effects of Trintellix include:

Severe side effects

Trintellix can also cause severe side effects. When deciding on the best treatments, a person can work with their healthcare provider to determine the risks of treating depression versus not treating it.

Severe side effects of Trintellix include the following:


Increased suicidal thoughts or actions

In the first few months of taking Trintellix, there are risks of increased suicidal thoughts or actions. The FDA advise people to pay close attention to how they are feeling and talk to their healthcare provider about any new or sudden changes in their mood, behavior, thoughts, or feelings.


Serotonin syndrome

Serotonin syndrome is a potentially life-threatening condition that can occur when a person takes Trintellix with other medication. The symptoms of serotonin syndrome include:

  • agitation
  • hallucinations
  • poor muscle control or twitching
  • a rapid heartbeat
  • sweating or fever
  • nausea and diarrhea

Bleeding or bruising

Trintellix can increase a person’s risk of abnormal bleeding or bruising, especially if a person takes it with the blood thinner warfarin, a nonsteroidal anti-inflammatory drug (NSAID) or Aspirin.

Hypomania

Trintellix can cause manic episodes. Symptoms include:

  • greatly increased energy
  • excessive happiness or irritability
  • talking and thinking very fast
  • risky behavior

Visual problems

Some people are at risk of eye problems linked with Trintellix. People may experience eye pain, changes in vision, and swelling or redness around the eye.

Low sodium levels

Trintellix can lead to low levels of salt (sodium) in the blood, which can cause the following symptoms:

  • headache
  • difficulty concentrating
  • confusion
  • weakness
  • unsteadiness on the feet

In severe cases, it can cause hallucinations, fainting, coma, and can be fatal without treatment.


Drug interactions

Trintellix may cause interactions with other medications that a person may be taking.

One of the most common drug interaction issues involves taking Trintellix while using monoamine oxidase inhibitors (MAOIs), which are another form of antidepressant. Using an MAOI medication with Trintellix may cause problems, such as:

People should not take a MAOI within 21 days of stopping Trintellix, and wait for 14 days after taking an MAOI before starting Trintellix.

A person should avoid taking medications that increase serotonin levels in the body. Some examples to avoid include:

A person should also avoid taking blood thinners as they can increase the risk of stomach bleeding. Some examples include warfarin and Aspirin.

Some medications can increase the effectiveness of Trintellix, which means a person can take lower doses of Trintellix. Examples of these medicines include:

Other medications may cause Trintellix to become less effective. A doctor may need to prescribe higher doses of Trintellix if a person is taking one of the following drugs:

  • phenobarbital
  • carbamazepine
  • rifampin
  • primidone
  • phenytoin

A person should also inform their doctor about any vitamins or supplements they are taking before they start taking Trintellix. Some vitamins or supplements may interact with Trintellix.

A person should discuss their medical history and medications, including supplements, with their doctor before starting Trintellix. They should also let their doctor know they are taking Trintellix to help avoid issues from drug interactions.

Cost

Trintellix is available only as a prescription. People with insurance will likely have to pay a slightly higher premium for brand name medications, such as Trintellix. Those without insurance may be able to find coupons or other price reductions to help cover the cost.

A healthcare provider may be able to suggest alternative treatments with the same levels of effectiveness and lower costs.
