About Fetzima

Overview

Fetzima contains levomilnacipran, a serotonin and norepinephrine reuptake inhibitor (SNRI), in extended-release capsules. It is used to treat major depressive disorder in adults. Its exact antidepressant action is unknown, but it is thought to work by reducing the reuptake of serotonin and norepinephrine, increasing their availability in the central nervous system. Fetzima is not approved for fibromyalgia, and its safety and effectiveness for that condition have not been established.

What it treats

Major depressive disorder (MDD) in adults.

Safety information

Side effects

Common side effects include nausea, constipation, increased sweating, vomiting, a faster heartbeat, palpitations (feeling your heart racing or pounding), difficulty getting or keeping an erection, and ejaculation problems. Contact a doctor if you develop serious side effects, including allergic reactions, serotonin syndrome, increased blood pressure or heart rate, unusual bleeding, angle-closure glaucoma, difficulty starting urination or inability to urinate, mania or hypomania, seizures, or low blood sodium. Serotonin syndrome can occur with Fetzima alone, and the risk increases when it is taken with other medicines that affect serotonin. Seek urgent medical help for suicidal thoughts or behaviour; the label highlights this risk in adolescents and young adults. Sexual problems and symptoms after stopping treatment can also occur. Discuss these with your prescriber before changing or stopping treatment. Blood pressure should be monitored regularly during treatment. Taking Fetzima with NSAIDs, aspirin, other antiplatelet medicines, warfarin or other anticoagulants may increase the risk of bleeding.

A boxed warning is the strongest warning the US Food and Drug Administration requires on a medicine label. Text is taken from the official label, with internal section references removed.

When to call your doctor

- Seek immediate medical attention for thoughts of suicide or suicidal behavior. - Get urgent help if you have a seizure. - Seek urgent care if you cannot pass urine or have difficulty starting to urinate. - Get immediate medical attention for unusual bleeding. - Seek urgent care for a racing or pounding heartbeat.

If symptoms are severe or getting worse quickly, seek emergency care rather than waiting.

Before taking this medicine

Do not take Fetzima if you are allergic to levomilnacipran, milnacipran hydrochloride or any of its other ingredients. Do not take Fetzima with a monoamine oxidase inhibitor (MAOI) used to treat psychiatric disorders, or within 14 days of stopping one. Do not start a psychiatric MAOI within 7 days of stopping Fetzima. Do not start Fetzima while receiving linezolid or intravenous methylene blue. These combinations increase the risk of serotonin syndrome. Conditions and medicines requiring caution include: • High blood pressure or a raised heart rate. High blood pressure should be controlled before treatment, and blood pressure monitored regularly during treatment. • Other medicines that affect serotonin, which increase the risk of serotonin syndrome. This can also occur with Fetzima alone. • NSAIDs, aspirin, other antiplatelet medicines, warfarin or other anticoagulants, which may increase bleeding risk. • Untreated narrow angles in the eyes, because of the risk of angle-closure glaucoma. • Difficulty starting urination or inability to empty the bladder. • Bipolar disorder or a history of seizures. Screening for bipolar disorder is needed before treatment because mania or hypomania may occur. • Pregnancy, particularly use in the third trimester, which may increase the risk of breathing problems, unstable temperature, feeding difficulties, low muscle tone, tremor or irritability in the newborn. Fetzima may also cause low blood sodium and sexual dysfunction. Stopping treatment can cause discontinuation symptoms; discuss stopping with your prescriber.

Interactions

Tell your doctor if you take a medicine that strongly inhibits the enzyme CYP3A4, as this limits the dose of Fetzima they can prescribe.
