A small number of children, teenagers, and young adults (up to 24 years of age) who took antidepressants ('mood elevators') such as amoxapine 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, experts are not sure about how great this risk is and how much it should be considered in deciding whether a child or teenager should take an antidepressant. Children younger than 18 years of age should not normally take amoxapine, but in some cases, a doctor may decide that amoxapine 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 amoxapine or other antidepressants even if you are an adult over age 24. 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 when you are unable to seek treatment on your own.
Your healthcare provider will want to see you often while you are taking amoxapine, 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 amoxapine. 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: Web Site.
No matter 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 medicine prescribed?
Amoxapine is used to treat depression. Amoxapine is in a class of medications called tricyclic antidepressants (TCAs). 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?
Amoxapine comes as a tablet to take by mouth. It is usually taken one or more times a day. If you take amoxapine once a day, you should take it at bedtime. Try to take amoxapine at around the same time(s) 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 amoxapine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
It may take several weeks or longer for you to feel the full effect of amoxapine. Continue to take amoxapine even if you feel well. Do not stop taking amoxapine without talking to your doctor. Your doctor probably will want to decrease your dose gradually.
Are there OTHER USES for this medicine?
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
What SPECIAL PRECAUTIONS should I follow?

Your doctor will probably tell you not to take amoxapine. If you stop taking amoxapine, you should wait at least 14 days before you start to take an MAO inhibitor.
