A small number of children, teenagers, and young adults (up to 24 years of age) who took antidepressants (‘mood elevators’) such as nefazodone 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. However, there are also risks when depression is not treated in children and teenagers. Talk to your child’s doctor about these risks and whether your child should take an antidepressant. Children younger than 18 years of age should not normally take nefazodone, but in some cases, a doctor may decide that nefazodone 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 nefazodone 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 nefazodone, especially at the beginning of your treatment. Be sure to keep all appointments for office visits with your doctor.
The doctor or pharmacist will give you the manufacturer’s patient information sheet (Medication Guide) when you begin treatment with nefazodone. Read the information carefully and ask your doctor or pharmacist if you have any questions. You also can obtain the Medication Guide from the FDA website: http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm.
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.
Nefazodone may cause liver damage, which can be severe or life-threatening. Tell your doctor if you have or have ever had liver disease. If you experience any of the following symptoms, call your doctor immediately: nausea, vomiting, loss of appetite, extreme tiredness, lack of energy, yellowing of the skin or eyes, unusual bleeding or bruising, dark-colored urine, pain in the upper right part of the stomach, or flu-like symptoms.
Keep all appointments with your doctor and the laboratory. Your doctor may order certain tests to check your body’s response to nefazodone.
Why is this medication prescribed?
Nefazodone is used to treat depression. Nefazodone is in a class of medications called serotonin modulators. It works by increasing the amounts of certain natural substances in the brain that are needed to maintain mental balance.
How should this medicine be used?
Nefazodone comes as a tablet to take by mouth. It is usually taken two times a day with or without food. Take nefazodone 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 nefazodone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor may start you on a low dose of nefazodone and gradually increase your dose, not more than once every week.
It may take several weeks or longer for you to feel the full benefit of nefazodone. Continue to take nefazodone even if you feel well. Do not stop taking nefazodone without talking to your doctor. If your doctor tells you to stop taking nefazodone, your doctor will probably want to decrease your dose gradually.

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).
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.
