Precautions & Cautions
Before engaging in activities that require your full attention, such as driving, wait until you understand how this medication affects you.
To minimize the risk of side effects, do not abruptly stop taking this medication without first consulting your doctor. If you need to discontinue use, your doctor will provide guidance on how to gradually stop taking it.
As directed by your doctor, regularly have your blood work and other laboratory tests checked. Additionally, monitor your blood pressure and heart rate as instructed by your doctor.
While taking this medication, it is recommended that you avoid consuming alcohol. Before using marijuana, cannabis, or any prescription or over-the-counter drugs that may cause drowsiness, consult with your doctor.
Be aware that this medication may increase the risk of bleeding, which can be life-threatening in some cases. Discuss this risk with your doctor.
Certain individuals may have a higher risk of developing eye problems while taking this medication. Your doctor may recommend an eye exam to assess your risk. If you experience eye pain, changes in vision, or swelling and redness in or around the eye, contact your doctor immediately.
This medication can cause low sodium levels, which can be life-threatening and lead to seizures, loss of consciousness, breathing difficulties, or death.
If you are 65 years or older, use this medication with caution, as you may be more susceptible to side effects.
If you are pregnant, plan to become pregnant, or are breastfeeding, inform your doctor. You and your doctor will need to discuss the benefits and risks of taking this medication. Taking this medication during the third trimester of pregnancy may increase the risk of bleeding after delivery and potentially cause health problems in the newborn. If you are breastfeeding, you and your doctor will need to discuss any potential risks to your baby.
Overdose Information
Overdose Symptoms:
- Tachycardia
- Hypertension
- Somnolence
- Nausea
- Vomiting
- Dizziness
- Seizures
- Serotonin syndrome
What to Do:
Seek immediate medical attention or call Poison Control at 1-800-222-1222. Management should include general supportive measures, monitoring of vital signs, and cardiac and respiratory function. There is no specific antidote for levomilnacipran overdose. Activated charcoal may be considered. Due to the large volume of distribution, forced diuresis, dialysis, hemoperfusion, and exchange transfusion are unlikely to be beneficial.
Drug Interactions
Contraindicated Interactions
- Monoamine Oxidase Inhibitors (MAOIs) (e.g., phenelzine, tranylcypromine, selegiline, isocarboxazid)
- Linezolid
- Intravenous Methylene Blue
Major Interactions
- Serotonergic drugs (e.g., SSRIs, other SNRIs, triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, buspirone, St. John's Wort) - increased risk of serotonin syndrome
- Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin, ritonavir) - increased levomilnacipran exposure
- Drugs that increase blood pressure or heart rate (e.g., other SNRIs, stimulants, decongestants) - additive effects
- Anticoagulants/Antiplatelets (e.g., warfarin, aspirin, NSAIDs) - increased risk of bleeding
Moderate Interactions
- Moderate CYP3A4 inhibitors (e.g., erythromycin, diltiazem, verapamil) - increased levomilnacipran exposure
- Alcohol - may enhance CNS effects
Minor Interactions
- Not available
Monitoring
Baseline Monitoring
Rationale: SNRIs can cause dose-dependent increases in BP and HR.
Timing: Prior to initiation and periodically during treatment.
Rationale: Assess baseline depressive symptoms and risk of suicidality.
Timing: Prior to initiation.
Rationale: Risk of hyponatremia, especially in elderly or volume-depleted patients.
Timing: Consider in at-risk patients prior to initiation.
Routine Monitoring
Frequency: Regularly, especially during dose titration and periodically thereafter.
Target: Maintain within normal limits or patient's baseline.
Action Threshold: Significant or sustained increases (e.g., >10-15 mmHg systolic or diastolic, or >10-15 bpm HR) may warrant dose reduction or discontinuation.
Frequency: Frequently during initial therapy (first few months) and dose changes, then periodically.
Target: Improvement in depressive symptoms without emergence of adverse psychiatric events.
Action Threshold: Worsening depression, emergence of suicidal thoughts, or signs of mania/hypomania require immediate assessment and intervention.
Frequency: Periodically, especially in elderly, volume-depleted, or those on diuretics.
Target: 135-145 mEq/L
Action Threshold: Hyponatremia (<135 mEq/L) requires investigation and potential discontinuation.
Symptom Monitoring
- Worsening depression
- Suicidal thoughts or behavior (especially in young adults)
- Unusual changes in behavior (e.g., agitation, irritability, aggression, panic attacks, insomnia, impulsivity, akathisia, hypomania, mania)
- Signs of serotonin syndrome (e.g., agitation, hallucinations, delirium, coma, tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia, tremor, rigidity, myoclonus, hyperreflexia, incoordination, GI symptoms)
- Signs of hyponatremia (e.g., headache, difficulty concentrating, memory impairment, confusion, weakness, unsteadiness, falls, severe and more acute symptoms include hallucinations, syncope, seizure, coma, respiratory arrest)
- New or worsening hypertension
- Urinary hesitation or retention
- Visual disturbances (e.g., blurred vision, eye pain, halos around lights) - risk of angle-closure glaucoma
Special Patient Groups
Pregnancy
Use during pregnancy should be avoided unless the potential benefit justifies the potential risk to the fetus. Neonates exposed to SNRIs late in the third trimester have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding. These complications can arise immediately upon delivery.
Trimester-Specific Risks:
Lactation
Levomilnacipran is excreted into human milk. Due to the potential for serious adverse reactions in breastfed infants, including agitation, irritability, and poor feeding, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Pediatric Use
Safety and effectiveness have not been established in pediatric patients. Fetzima is not approved for use in pediatric patients. Antidepressants carry a Black Box Warning for increased risk of suicidality in children, adolescents, and young adults.
Geriatric Use
No overall differences in safety or effectiveness were observed between geriatric and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Elderly patients may be at increased risk for hyponatremia and falls. Dose adjustments may be necessary for elderly patients with renal impairment.
Clinical Information
Clinical Pearls
- Levomilnacipran has a higher norepinephrine reuptake inhibition ratio compared to serotonin, which may differentiate its side effect profile and efficacy from other SNRIs.
- Always titrate the dose gradually to minimize side effects, especially blood pressure and heart rate increases.
- Monitor blood pressure and heart rate regularly, particularly in patients with pre-existing cardiovascular conditions.
- Counsel patients on the Black Box Warning regarding suicidality, especially young adults, and the importance of reporting any worsening mood or behavioral changes.
- Be vigilant for signs of serotonin syndrome, especially when co-administered with other serotonergic agents.
- Discontinuation syndrome can occur if the drug is stopped abruptly; taper the dose gradually over at least 1-2 weeks.
- The capsule shell may be excreted in the stool, which is normal and does not mean the medication was not absorbed.
Alternative Therapies
- Other SNRIs (e.g., Venlafaxine, Desvenlafaxine, Duloxetine)
- SSRIs (e.g., Fluoxetine, Sertraline, Paroxetine, Citalopram, Escitalopram)
- Atypical antidepressants (e.g., Bupropion, Mirtazapine, Vortioxetine, Vilazodone)
- Tricyclic Antidepressants (TCAs)
- MAOIs (reserved for refractory cases)
