Strattera basics
Strattera contains the active ingredient atomoxetine.
Strattera is a brand-name medication that’s also available as the generic drug atomoxetine.

Strattera is used to treat ADHD in adults and children ages 6 years and older.
ADHD is a mental health condition that causes impulsive behaviors and excessive hyperactivity. Both children and adults can have ADHD. It may cause symptoms such as trouble sitting still, difficulty focusing on tasks, and changes in energy levels. Symptoms differ based on aspects of ADHD you experience, such as difficulty focusing, hyperactivity, or impulsivity.
How does Strattera work for ADHD?
How a drug works is referred to as its mechanism of action. Strattera’s mechanism of action for treating ADHD isn’t fully understood. However, it’s thought that the drug increases the level of a neurotransmitter called norepinephrine in your brain. It’s thought this action may ease symptoms of ADHD.

What might help
If you have mild symptoms of an allergic reaction, such as a mild rash, call your doctor right away. They may suggest a treatment to manage your symptoms and can determine whether you should keep taking Strattera.

Your doctor will recommend the dosage of Strattera that’s right for you. Below are commonly used dosages, but always take the dosage your doctor prescribes.
Form and strengths
Strattera is available as an oral capsule in the following strengths:
- 10 milligrams (mg)
- 18 mg
- 25 mg
- 40 mg
- 60 mg
- 80 mg
- 100 mg
Recommended dosages
In adults and children weighing more than 70 kilograms (kg), or about 154 pounds, the recommended starting Strattera dosage is 40 mg taken once per day in the morning. After at least 3 days, your doctor may increase your dosage to 80 mg, taken either once daily in the morning or split into 40 mg taken twice daily.
For children who weigh 70 kg or less, the recommended starting dose is 0.5 mg per kg body weight (mg/kg) taken once per day. After at least 3 days, your child’s doctor may increase the dose to 1.2 to 1.4 mg/kg per day. This may be given as one daily dose, or split evenly into two doses.
For example, in a child weighing 30 kg (about 66 pounds), the starting dose may be 15 mg. Since Strattera doesn’t come in a 15-mg strength, the doctor will round down to 10 mg or up to 18 mg for your child’s starting dose.

Pregnancy and breastfeeding

Boxed warning
Strattera has a boxed warning. A boxed warning is the most serious warning from the Food and Drug Administration (FDA) about drug effects that may be dangerous.
Risk of suicidal thoughts in children: In short-term studies, Strattera increased the risk of suicidal thoughts (also called suicidal ideations) in children. It doesn’t appear that this risk applies to adults taking Strattera. This side effect was very rare in studies, and no suicides were observed. It’s important to note that mental health conditions, such as depression, often occur with ADHD, and these conditions can raise the risk of suicidal thoughts. Strattera is not approved for treating depression and should not be used in place of approved treatments for depression.
In studies, this risk was only noted during the first month of treatment. When your child first begins treatment with Strattera, closely monitor their behaviors and mood. Immediately report new or unusual behaviors, such as excessive agitation or irritability, to your child’s doctor.
Other warnings
Strattera can sometimes cause harmful effects in people who have certain conditions. This is known as a drug-condition interaction. Other factors may also affect whether Strattera is a good treatment option for you.
Talk with your doctor about your health history before you take Strattera. Be sure to tell them if any of the following factors apply to you:
- heart or blood vessel condition, such as arrhythmia, high blood pressure, or cardiomyopathy
- liver condition, such as cirrhosis
- mental health condition, such as depression or bipolar disorder
- narrow angle glaucoma
- pheochromocytoma
- urinary retention
- previous allergic reaction to Strattera
- pregnancy
- breastfeeding

What should I know about Strattera vs. Adderall?
Strattera and Adderall (amphetamine/dextroamphetamine) are both prescribed to treat ADHD in adults and certain children. Unlike Adderall, Strattera is not a stimulant. And Strattera is only available as immediate-release capsules. On the other hand, Adderall is available in both immediate-release tablets and as an extended-release capsule called Adderall XR. “Extended-release” means the drug is slowly released from the capsule into your body over time, allowing for once-daily dosing.
Your doctor or pharmacist can answer questions you have about how Strattera and Adderall compare.
Is Strattera similar to Qelbree?
Strattera and Qelbree (viloxazine) are both prescribed to treat ADHD in adults and certain children. They belong to the same medication class, called selective norepinephrine reuptake inhibitors. And neither Strattera nor Qelbree are stimulants or controlled substances.
However, both medications have a boxed warning, although it varies slightly. Strattera has a boxed warning about the risk of suicidal thoughts in children. Qelbree, on the other hand, has a boxed warning for the risk of suicidal thoughts and behaviors in both adults and children.

How does Strattera compare with Wellbutrin?
Strattera and Wellbutrin are medications approved for different uses. Strattera is approved to treat ADHD in adults and certain children. Wellbutrin, on the other hand, is approved to treat depression and seasonal affective disorder.
However, Wellbutrin is sometimes prescribed off-label to treat ADHD in adults. “Off-label” use refers to prescribing a medication for a condition other than its FDA-approved uses.
Talk with your doctor or pharmacist if you’d like to learn more about Strattera or Wellbutrin, including off-label uses.
Is Strattera a controlled substance?
No, Strattera is not a controlled substances. This is one way Strattera is different from certain other ADHD treatments, such as Adderall (amphetamine/dextroamphetamine) and Ritalin (methylphenidate).
A controlled substance is a drug regulated by the Drug Enforcement Administration (DEA) to help prevent misuse. Controlled substances have varying potential for misuse as well as psychological and physical dependence. “Misuse” refers to using a medication in a way other than how it’s prescribed, such as to feel high. Continually misusing a medication can lead to substance use disorder (also called drug abuse).
Notably, Strattera did not cause withdrawal in studies. And it appears not to have addiction or misuse potential.
