Levomilnacipran

pronounced as (lee'' voe mil na' si pran)

IMPORTANT WARNING:

A small number of children, teenagers, and young adults (up to 24 years of age) who took antidepressants ('mood elevators') such as levomilnacipran during clinical studies became suicidal (thinking about harming or killing oneself or planning or trying to do so). Children, teenagers, and young adults who take antidepressants to treat depression or other mental illnesses may be more likely to become suicidal than children, teenagers, and young adults who do not take antidepressants to treat these conditions. This risk should be considered and compared with the potential benefit in the treatment of depression, in deciding whether a child or teenager should take an antidepressant. Children younger than 18 years of age should not normally take levomilnacipran, but in some cases, a doctor may decide that levomilnacipran is the best medication to treat a child's condition.

You should know that your mental health may change in unexpected ways when you take levomilnacipran or other antidepressants even if you are an adult over 24 years of age. You may become suicidal, especially at the beginning of your treatment and any time that your dose is increased or decreased. You, your family, or your caregiver should call your doctor right away if you experience any of the following symptoms: new or worsening depression; thinking about harming or killing yourself, or planning or trying to do so; extreme worry; agitation; panic attacks; difficulty falling asleep or staying asleep; aggressive behavior; irritability; acting without thinking; severe restlessness; and frenzied abnormal excitement. Be sure that your family or caregiver knows which symptoms may be serious so they can call the doctor if you are unable to seek treatment on your own.

Your healthcare provider will want to see you often while you are taking levomilnacipran, especially at the beginning of your treatment. Be sure to keep all appointments for office visits with your doctor.

Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with levomilnacipran and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.

No matter what your age, before you take an antidepressant, you, your parent, or your caregiver should talk to your doctor about the risks and benefits of treating your condition with an antidepressant or with other treatments. You should also talk about the risks and benefits of not treating your condition. You should know that having depression or another mental illness greatly increases the risk that you will become suicidal. This risk is higher if you or anyone in your family has or has ever had bipolar disorder (mood that changes from depressed to abnormally excited) or mania (frenzied, abnormally excited mood) or has thought about or attempted suicide. Talk to your doctor about your condition, symptoms, and personal and family medical history. You and your doctor will decide what type of treatment is right for you.

Why is this medication prescribed?

Levomilnacipran is used to treat depression. Levomilnacipran is in a class of medications called selective serotonin and norepinephrine reuptake inhibitors (SNRIs). It works by increasing the amount of serotonin and norepinephrine, natural substances in the brain that helps maintain mental balance.

How should this medicine be used?

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.

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 drink or have ever drunk large amounts of alcohol or use or have ever used street drugs or have ever overused prescription medications.

  • tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. If you become pregnant while taking levomilnacipran, call your doctor.
  • avoid use of alcoholic beverages while you are taking levomilnacipran.
  • you should know that levomilnacipran may make you drowsy and may affect your judgment, thinking, and movements. 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 and pulse (heart rate) should be checked before starting treatment and 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.

What should I know about storage and disposal of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from light, excess heat and moisture (not in the bathroom).

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
