Precautions and Contraindications
If you are allergic to levomilnacipran or milnacipran, you should not use Fetzima. It is also not advisable if you have narrow-angle glaucoma. If Fetzima is mixed with a monoamine oxidase inhibitor (MAOI), it can cause a potentially life-threatening reaction. Do not take Fetzima within seven days before or 14 days after you have taken an MAOI, including the antibiotic linezolid or intravenous methylene blue. Levomilnacipran has also been found to enhance the effects of medication known to increase bleeding (such as ibuprofen, warfarin, and aspirin) and to increase the levels and effects of the following drugs:
Antibiotics including Biaxin (clarithromycin) and Zithromax (azithromycin) Antifungals such as Diflucan (fluconazole), Nizoral (ketoconazole), Sporanox (itraconazole) HIV medications including Norvir (ritonavir) and Crixivan (indinavir) Medication for mood, anxiety, psychotic or thought disorders, including tricyclic antidepressants, lithium, fentanyl, tryptophan, selective serotonin reuptake inhibitors (SSRIs), other serotonin norepinephrine reuptake inhibitors (SNRIs), buspirone, amphetamines, or antipsychotics Triptans used to treat migraine headaches Tramadol for moderate to severe pain Diuretics (water pills) Over-the-counter supplements such as tryptophan or St. John’s Wort
According to the manufacturer, you should also talk to your doctor if you are pregnant, nursing, or planning to become pregnant or to breastfeed, or have any of the following health conditions:
High blood pressureHeart problemsKidney problems (Fetzima can cause renal impairment in relatively low doses)Bleeding problems (the drug can increase your risk of bleeding and bruising)Trouble urinatingAlcohol use disorderLow sodium levels in your bloodMania or bipolar disorderSeizures or convulsions
If Fetzima doesn’t work with your health history and current medications, consider asking your doctor whether a different SNRI or another type of reuptake inhibitor would work for you. Some possible options may include:
Other SNRIs such as Cymbalta (duloxetine), or Pristiq (desvenlafaxine) Norepinephrine Reuptake Inhibitors (NRIs)
Dosage
Fetzima is often prescribed at a low dose (20 milligrams), which is gradually increased over two days to 40mg per day. According to the manufacturer, the recommended dose ranges from 40mg to 120mg, however it’s up to your doctor to determine the right dose for you. Always check your prescription and ask your doctor or pharmacist if you have any questions regarding dosage.
How to Take and Store
Take your prescription on the schedule and follow the exact dosage your doctor prescribed. The manufacturer recommends taking Fetzima daily, at the same time each day, with or without food. Swallow the capsule whole; don’t open and sprinkle in food, crush, or chew. It’s best to store Fetzima at room temperature (77°F) and to keep out of the reach of children. If you miss a dose, take the missed dose as soon as you remember. If it’s almost time for the next dose, skip the missed dose and take your next dose at the regular time. Don’t take two doses of Fetzima at the same time.

Warnings and Interactions
Fetzima is not recommended if you are pregnant or breastfeeding (it’s unknown if the drug passes through breastmilk), so you should contact your doctor immediately if you become pregnant while taking the drug. Fetzima can cause sleepiness or impact your ability to make decisions, think clearly, or react quickly. Do not drive or operate heavy machinery until you know how the drug affects you. Like all antidepressants, Fetzima has a black box warning of an increased risk of suicidal thoughts or actions in some children, teenagers, or young adults within the first few months of treatment. It’s also important to keep schedule visits with your healthcare provider to discuss any ongoing symptoms or side effects. Don’t try and stop the medication on your own. Although your first impulse when you experience intolerable side effects may be to stop taking your medication, it’s never a good idea to discontinue your antidepressant without first consulting with your doctor. Your depression may return or even become worse if you suddenly stop taking your antidepressant. In addition, you run the risk of experiencing what is known as discontinuation syndrome, which includes a set of unpleasant symptoms such as nausea, fatigue, headaches, strange neurological sensations, and muscle aches. Your doctor will be able to best advise you about methods to better cope with or eliminate side effects and whether it’s a good idea to switch to a different antidepressant that will present fewer problems for you.
