10 mg, 18 mg, 25 mg, 40 mg, 60 mg, 80 mg and 100 mg hard capsules 

What Atomoxetine Orion is and what it is used for

What is it used for

Atomoxetine Orion contains atomoxetine and is used to treat attention deficit hyperactivity disorder ( ADHD ). It uses:

  • in children from 6 years of age
  • in adolescents
  • in adults.

It is used only as part of a complete treatment program of the disease which also includes treatment that does not involve drugs, such as talk and behavioral therapy.

The drug is not for the treatment of ADHD in children under 6 years because it is not known if the treatment works or is safe for these people.

In adults, this drug is used to treat ADHD when the symptoms are very bothersome and affect your job or social life and when you had symptoms of the disease as a child.

How does it work

This drug increases the amount of norepinephrine in the brain. Noradrenaline is a naturally occurring neurotransmitter that increases attention span and reduces impulsivity and hyperactivity in patients with ADHD . This medicine helps control ADHD symptoms. This drug is not a central stimulant and is therefore not addictive.

It may take a few weeks after you start taking the medicine before the medicine reaches full effect.

About ADHD 
Children and adolescents with ADHD experience that it is:

  • difficult to sit still and
  • difficult to concentrate.

It is not their fault that they can not do this. Many children and adolescents have difficulty with these things, but with ADHD , this can create problems in everyday life. Children and adolescents with ADHD may have difficulty learning and doing homework. They find it difficult to behave at home, at school or in other places. ADHD does not affect the intelligence of children and adolescents.

Adults with ADHD have difficulties with the same things that children experience as difficult, but this can mean that they have problems with:

  • work
  • relationships
  • low self-esteem
  • training

Atomoxetine contained in Atomoxetine Orion may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.

  • is allergic to atomoxetine or any of the other ingredients of this medicine (listed in section 6).
  • during the last 14 days has taken a drug belonging to the group of monoamine oxidase inhibitors ( MAOIs ), e.g. feeling. MAO inhibitors are used, among other things, to treat depression and other mental problems. Concomitant use of Atomoxetine Orion and an MAOI may cause serious side effects or be life-threatening. At least 14 days must have passed after stopping treatment with this medicine before you can start taking an MAOI .
  • have an eye disease called glaucoma with a narrow ventricular angle (increased pressure inside the eye).
  • have severe heart problems, which may be affected by an increase in heart rate and / or blood pressure , as it may be an effect of Atomoxetine Orion.

  • has a tumor in the adrenal gland ( pheochromocytoma ).

Do not take Atomoxetine Orion if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking this medicine. This is because this medicine may make these problems worse.
