Strattera (Generic Atomoxetine)
Actual product appearance may differ slightly.
Studies have shown that children and teenagers with attention-deficit hyperactivity disorder (ADHD; more difficulty focusing, controlling actions, and remaining still or quiet than other people who are the same age) who take atomoxetine are more likely to think about killing themselves than children and teenagers with ADHD who do not take atomoxetine.
While your child is taking atomoxetine, you should watch his or her behavior very carefully, especially at the beginning of treatment and any time his or her dose is increased or decreased. Your child may develop serious symptoms very suddenly, so it is important to pay attention to his or her behavior every day. Ask other people who spend a lot of time with your child, such as brothers, sisters, and teachers to tell you if they notice changes in your child’s behavior. Call your child’s doctor right away if your child experiences any of these symptoms: acting more subdued or withdrawn than usual; feeling helpless, hopeless, or worthless; new or worsening depression; thinking or talking about harming or killing him- or herself or planning or trying to do so; extreme worry; agitation; panic attacks; difficulty falling asleep or staying asleep; irritability; aggressive or violent behavior; acting without thinking; extreme increase in activity or talking; frenzied, abnormal excitement; or any other sudden or unusual changes in behavior.
Your child’s doctor will want to see your child often while he or she is taking atomoxetine, especially at the beginning of his or her treatment. Your child’s doctor may also want to speak with you or your child by telephone from time to time. Be sure that your child keeps all appointments for office visits or telephone conversations with his or her doctor.
Your doctor or pharmacist will give you the manufacturer’s patient information sheet (Medication Guide) when you begin treatment with atomoxetine 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) or the manufacturer’s website to obtain the Medication Guide.
Talk to your doctor about the risks of giving atomoxetine to your child, of using other treatments for your child’s condition, and of not treating your child’s condition.
Why is this medication prescribed?
Atomoxetine is used as part of a total treatment program to increase the ability to pay attention and decrease impulsiveness and hyperactivity in children and adults with ADHD. Atomoxetine is in a class of medications called selective norepinephrine reuptake inhibitors. It works by increasing the levels of norepinephrine, a natural substance in the brain that is needed to control behavior.
How should this medicine be used?
Atomoxetine comes as a capsule to take by mouth. It is usually taken either once a day in the morning, or twice a day in the morning and late afternoon or early evening. Atomoxetine may be taken with or without food. Take atomoxetine 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 atomoxetine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow atomoxetine capsules whole; do not open, chew, or crush them. If a capsule is accidentally broken or opened, wash away the loose powder with water right away. Try not to touch the powder and be especially careful not to get the powder in your eyes. If you do get powder in your eyes, rinse them with water right away and call your doctor.
Your doctor will probably start you on a low dose of atomoxetine and increase your dose after at least 3 days. Your doctor may increase your dose again after 2–4 weeks. You may notice improvement in your symptoms during the first week of your treatment, but it may take up to one month for you to feel the full benefit of atomoxetine.
Atomoxetine may help to control the symptoms of ADHD but will not cure the condition. Continue to take atomoxetine even if you feel well. Do not stop taking atomoxetine without talking to your doctor.

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
