Why is this medication prescribed?
Milnacipran is used to treat fibromyalgia (a long-lasting condition that may cause pain, muscle stiffness and tenderness, tiredness, and difficulty falling asleep or staying asleep). Milnacipran 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 that help stop the movement of pain signals in the brain.
How should this medicine be used?
Milnacipran comes as a tablet to be taken by mouth. It is usually taken two times a day. Milnacipran may be taken with or without food, but taking it with food will decrease the chance that milnacipran will upset your stomach. Take milnacipran at around the same times 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 milnacipran exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor will start you on a low dose of milnacipran and gradually increase your dose during the first week of treatment.
Milnacipran may help control the symptoms of fibromyalgia, but will not cure it. Do not stop taking milnacipran without talking to your doctor. If you suddenly stop taking milnacipran, you may experience withdrawal symptoms such as mood changes, irritability, agitation, dizziness, numbness or tingling in the hands or feet, anxiety, confusion, headache, tiredness, difficulty falling asleep or staying asleep, ringing in the ears, abnormal excitement, or seizures. Your doctor will probably decrease your dose gradually.

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 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
