Uses For levomilnacipran
Levomilnacipran is used to treat depression. It belongs to a group of medicines known as serotonin and norepinephrine reuptake inhibitors (SNRIs). These medicines are thought to work by increasing the activity of chemicals called serotonin and norepinephrine in the brain.
Levomilnacipran is available only with your doctor's prescription.
Before Using levomilnacipran
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For levomilnacipran, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to levomilnacipran or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Levomilnacipran is not approved for use in children. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of levomilnacipran in the elderly. However, elderly patients are more likely to have age-related kidney problems, which may require an adjustment in the dose for patients receiving levomilnacipran.

Precautions While Using levomilnacipran
It is very important that your doctor check your progress at regular visits to make sure levomilnacipran is working properly.
Do not take levomilnacipran with a monoamine oxidase (MAO) inhibitor (eg, isocarboxazid [Marplan®], phenelzine [Nardil®], selegiline [Eldepryl®], tranylcypromine [Parnate®]). Do not start taking levomilnacipran during the 2 weeks after you stop a MAO inhibitor. Wait 1 week after stopping levomilnacipran before you start taking a MAO inhibitor. If you take them together or do not wait the proper amount of time, you may develop confusion, agitation, restlessness, stomach or intestinal symptoms, a sudden high body temperature, an extremely high blood pressure, or severe convulsions.
Levomilnacipran may cause some teenagers and young adults to be agitated, irritable, or display other abnormal behaviors. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed. Some people may have trouble sleeping, get upset easily, have a big increase in energy, or start to act reckless. If you or your caregiver notice any of these unwanted effects, tell your doctor right away. Let the doctor know if you or anyone in your family has bipolar disorder (manic-depressive) or has tried to commit suicide.
Levomilnacipran may cause a serious condition called serotonin syndrome if taken together with some medicines. Do not use levomilnacipran with buspirone (Buspar®), fentanyl (Abstral®, Duragesic®), linezolid (Zyvox®), lithium (Eskalith®, Lithobid®), methylene blue injection, tryptophan, St. John's wort, amphetamines, or some pain or migraine medicines (eg, rizatriptan, sumatriptan, tramadol, Frova®, Imitrex®, Maxalt®, Relpax®, Ultram®, Zomig®). Check with your doctor first before taking any other medicines with levomilnacipran.
Levomilnacipran may increase your risk for bleeding problems. Make sure your doctor knows if you are also taking other medicines that thin the blood, such as aspirin, nonsteroidal antiinflammatory agents, also called NSAIDs (eg, diclofenac, ibuprofen, naproxen, Advil®, Aleve®, Celebrex®, Voltaren®), or warfarin (Coumadin®, Jantoven®).
Do not stop taking levomilnacipran without checking first with your doctor. Your doctor may want you to gradually reduce the amount you are taking before stopping it completely to decrease the chance of withdrawal effects. Some examples of withdrawal effects include agitation, breathing problems, chest pain, confusion, diarrhea, dizziness or lightheadedness, fast heartbeat, headaches, increased sweating, muscle pain, nausea, restlessness, runny nose, trouble sleeping, trembling or shaking, unusual tiredness or weakness, vision changes, or vomiting.
Levomilnacipran may cause hyponatremia (low sodium in the blood). This is more common in elderly patients, those who are taking diuretic medicines, or those who have less fluid in the body due to severe diarrhea or vomiting. Check with your doctor right away if you have confusion, a headache, memory problems, trouble concentrating, weakness, or feel unsteady when standing.
Levomilnacipran may cause some people to become dizzy, drowsy, or less alert than they are normally. Make sure you know how you react to levomilnacipran before you drive, use machines, or do anything else that could be dangerous if you are not alert.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
