Interactions

Drug-Drug interaction

Concurrent use with MAO inhibitors used for psychiatric disorders may result in serious, potentially fatal reactions; wait at least 14 days following discontinuation of MAO inhibitor before initiation of levomilnacipran. Wait at least 7 days after discontinuing levomilnacipran before initiation of MAO inhibitorConcurrent use of serotonergic drugs (including triptans, lithium, buspirone, fentanyl, tricyclics and tramadol ) may ↑ the risk of serotinin syndrome, especially during initiation and dose adjustment; also ↑ risk of coronary vasoconstriction and hypertension.Concurrent use with methylene blue or linezolid is contraindicated due to risk of serotonin syndromeConcurrent use of NSAIDs, aspirin, warfarin or otherdrugs that affect coagulation may ↑ the risk of bleeding.Blood levels and risk of toxicity ↑ by concurrent use of CYP3A4 inhitors including ketoconazole, clarithromycin, ritonavir ; daily dose should not exceed 80 mgConcurrent use of other medications that may ↑ blood pressure may ↑ risk of hypertensionConcurrent use with alcohol may cause a rapid release of drug and should be avoidedConcurrent use with other CNS-active medications, especially other NSRIs Concurrent use with St. John's wort or tryptophan may ↑ the risk of serotinin syndrome; also ↑ risk of coronary vasoconstriction and hypertension.

Extended-release capsules: 20 mg, 40 mg, 80 mg, 120 mg

Nursing implications

Nursing assessment

  • Monitor blood pressure and heart rate before and periodically during therapy. Treat per-existing hypertension and cardiac disease prior to therapy. Sustained hypertension may require discontinuation of therapy.
  • Monitor closely for notable changes in behavior that could indicate the emergence or worsening of suicidal thoughts or behavior or depression.
  • Lab Test Considerations: May cause hyponatremia.

Potential Nursing Diagnoses

Ineffective coping (Indications)
Risk for suicide (Adverse Reactions)

Implementation

  • Oral: Administer daily without regard to food. Swallow capsule whole; do not open, crush, or chew.

Patient/Family Teaching

  • Instruct patient to take levomilnacipran as directed at the same time each day. Take missed doses as soon as possible unless time for next dose; do not double dose. Do not stop abruptly; must be decreased gradually. Abrupt discontinuation may cause dysphoric mood, irritability, agitation, dizziness, paresthesia, electric shock sensation, anxiety, confusion, headache, lethargy, emotional lability, insomnia, hypomania, tinnitus and seizures. Advise patient to read Medication Guide prior to therapy and with each Rx refill in case of changes.
  • May cause drowsiness and may affect ability to make decisions or react quickly. Caution patient to avoid driving or other activities requiring alertness until response to medication is known.
  • Advise patient, family, and caregivers to look for activation of mania/hypomania and suicidality, especially during early therapy or dose changes. Notify health care professional immediately if thoughts about suicide or dying, attempts to commit suicide; new or worse depression or anxiety; agitation or restlessness; panic attacks; insomnia; new or worse irritability; aggressiveness; acting on dangerous impulses, mania, or other changes in mood or behavior or if symptoms of serotonin syndrome occur.
  • Caution patient of the risk or serotonin syndrome (agitation, hallucinations, changes in mental status, muscle twitching, fast heartbeat, high or low blood pressure, sweating or fever, nausea or vomiting, diarrhea, muscle stiffness or tightness), especially when taking triptans, tramadol, tryptophan supplements and other serotonergic or antipsychotic agents.
  • Instruct patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to avoid concurrent use of Rx, OTC, and herbal products, especially NSAIDs, aspirin, and warfarin, without consulting health care professional; may increase bleeding.
  • Instruct patient to notify health care professional if signs of hyponatremia (headache, difficulty concentrating, memory impairment, confusion, weakness, unsteadiness) occur.
  • Advise patient to avoid taking alcohol during levomilnacipran therapy.
  • Instruct patient to notify health care professional if pregnancy is planned or suspected or if breast feeding.
  • Encourage patient to maintain routine follow-up visits with health care provider to determine effectiveness.

Evaluation/Desired Outcomes

  • Increased sense of well-being
    • Renewed interest in surroundings. Need for therapy should be periodically reassessed.

Report provides a overview on following product profiles: Lexapro (Escitalopram), Viibryd (Vilazodone), Effexor (Venlafaxine), Cymbalta (Duloxetine), Pristiq (Desvenlafaxine), Fetzima (Levomilnacipran), Savella (Milnacipran), Norepinephrine-Dopamine Reuptake Inhibitors, Noradrenaline and Specific Serotonergic Antidepressants, Monoamine Oxidase Inhibitors, Brintellix (Vortioxetine), Tricyclic Antidepressants, Abilify (Aripiprazole), Seroquel XR (Quetiapine).
Levomilnacipran SR resulted in significant improvement in cognitive measures of attention and information processing in a phase III trial conducted in patients with major depressive disorder; the drug was approved in late July by the Food and Drug Administration under the trade name Fetzima.
Our first quarter performance was highlighted by strong revenue growth from Namenda XR, Linzess, Bystolic, Viibryd/ Fetzima, LoLoestrin Fe, Saphris, Estrace Cream as well as continued growth within our generics business, powered by strong sales of the generic versions of Concerta, Intuniv and the recent launch of our generic version of OxyContin.
Several important products have gained approval so far this year including oral multiple sclerosis drug Tecfidera, type II diabetes drug Invokana, Liptruzet (cholesterol), Fetzima (major depressive disorder), Imbruvica (mantle cell lymphoma), Gazyva (chronic lymphocytic leukemia) and Sovaldi (HCV).
13, 2014 /PRNewswire/ -- Decision Resources Group finds that in the unipolar depression* market, the expanding use of two recently approved therapies-Lundbeck/Takeda Pharmaceutical's Brintellix (vortioxetine), Actavis (formerly Forest Laboratories)/Pierre Fabre's Fetzima (levomilnacipran ER)-together with the forecasted launch of Otsuka Pharmaceutical/Lundbeck's brexpiprazole in the major pharmaceutical markets (United States, France, Germany, Italy, Spain, United Kingdom and Japan) will offset a steep near-term decline in sales resulting from the loss of market exclusivity for the two key drugs prescribed for unipolar depression-duloxetine (Eli Lilly/Shionogi's Cymbalta/Xeristar, generics) and the atypical antipsychotic Abilify (Bristol-Myers Squibb/Otsuka Pharmaceutical's aripiprazole).
The launch of generic versions of two key therapies-duloxetine and Abilify-will not only result in a dramatic near-term drop in sales due to extensive and rapid uptake of generics but also create market access pressures for newer agents launching in these drug classes: Fetzima and brexpiprazole, respectively.
Fetzima (levomilnacipran) is an SNRI indicated for the treatment of MDD and is only available in the US.
Detailed information on Fetzima including product description, safety and efficacy profiles as well as a SWOT analysis.
However, responses from surveyed managed care organization directors suggest that newer-to-market agents Forest Laboratories/Pierre Fabre's Fetzima, Takeda/Lundbeck's Brintellix and Dainippon Sumitomo/Sunovion's Latuda are in danger of remaining excluded from Medicare prescription drug formularies in one year's time, likely due to the widespread availability of inexpensive generics and greater cost containment pressures on these plans compared with commercial plans.
A larger percentage of surveyed PCPs responded they have prescribed Brintellix versus the percentage that reported prescribing Fetzima, and almost all surveyed PCPs who are familiar with Brintellix but have not yet prescribed the drug expect to prescribe it in the next 12 months.
The launch of Brintellix and two other emerging antidepressants by 2022-Eli Lilly's edivoxetine and Forest Laboratories/Pierre Fabre's Fetzima-will be insufficient to counteract this decline;edivoxetine and Fetzima will together reach just under $1 billion in sales across the major markets by 2022.
