Your doctor may need to change the doses of your medications or monitor you carefully for side effects. Many other medications may also interact with levomilnacipran, so be sure to tell your doctor about all the medications you are taking, even those that do not appear on this list.
- tell your doctor what herbal products and nutritional supplements you are taking, especially St. John’s wort and tryptophan.
- tell your doctor if you have or have ever had high blood pressure, urinary retention or problems urinating, low salt (sodium) levels in your blood, seizures, or kidney or heart disease.

- avoid the use of alcoholic beverages while you are taking levomilnacipran.
- you should know that levomilnacipran may make you drowsy. Do not drive a car or operate machinery until you know how this medication affects you.
- you should know that levomilnacipran may cause high blood pressure. Your blood pressure should be checked regularly while you are receiving levomilnacipran.
- you should know that levomilnacipran may cause angle-closure glaucoma (a condition where the fluid is suddenly blocked and unable to flow out of the eye causing a quick, severe increase in eye pressure which may lead to a loss of vision). Talk to your doctor about having an eye examination before you start taking this medication. If you have nausea, eye pain, changes in vision, such as seeing colored rings around lights, and swelling or redness in or around the eye, call your doctor or get emergency medical treatment right away.
Levomilnacipran comes as an extended-release (long-acting) capsule to take by mouth. It is usually taken once daily with or without food. Take levomilnacipran at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take levomilnacipran exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the capsules whole; do not open, chew, or crush them.
Your doctor may start you on a low dose of levomilnacipran and gradually increase your dose, not more than once every 2 days.
Levomilnacipran controls depression but does not cure it. It may take several weeks or longer before you feel the full benefit of levomilnacipran. Continue to take levomilnacipran even if you feel well. Do not stop taking levomilnacipran without talking to your doctor. Your doctor will probably decrease your dose gradually. If you suddenly stop taking levomilnacipran, you may experience withdrawal symptoms such as mood changes, agitation, irritability, dizziness, ringing in the ears, shock-like sensations, anxiety, confusion, tiredness, difficulty falling asleep or staying asleep, numbness or tingling in the arms, legs, hands, or feet, headache, increased sweating, seizures, or nausea. Tell your doctor if you experience any of these symptoms when your dose of levomilnacipran is decreased.
Keep all appointments with your doctor and the laboratory.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
