1. What is Atamax and what is it used for

What it is used for

Atamax contains atomoxetine and is used in the treatment of attention deficit hyperactivity disorder (ADHD). It is used:

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

It is used only as part of the complete treatment of the disease, which also requires non-drug treatments, such as counseling or behavioral therapy.

It is not used to treat ADHD in children under 6 years of age, as it is not known whether the drug works or is safe in this population.

In adults, this medication is used to treat ADHD when symptoms are very problematic and affect work or social life, and when symptoms of the disease were present in childhood.

How it works

This medication increases the amount of noradrenaline in the brain. This is a naturally produced chemical that increases attention and decreases impulsivity and hyperactivity in patients with ADHD. This medication has been prescribed to help control the symptoms of ADHD. This medication is not a stimulant and therefore does not cause addiction.

It may take a few weeks from the start of treatment with the medication until the symptoms improve completely.

About ADHD

Children and adolescents with ADHD find:

• difficulty sitting still
• difficulty concentrating

It's not their fault that they can't do these things. Many children and adolescents find this difficult. However, for patients with ADHD, this can cause problems in daily life. Children and adolescents with ADHD may have difficulty learning and doing homework. They have difficulty behaving well at home, at school, or in other places. ADHD does not affect a child's or adolescent's intelligence.

Adults with ADHD find it difficult to do all the things that children also find difficult, however, this can mean that they have problems with:

• work
• relationships
• low self-esteem
• education

2. What you need to know before taking Atamax

Do not takeAtamax:

• if you are allergic to atomoxetine or any of the other components of this medication (listed in section 6).
• if you have taken a medication called monoamine oxidase inhibitors (MAOIs) in the last two weeks, for example, phenelzine. MAOIs are sometimes used for depression and other mental disorders; taking Atamax with an MAOI could cause serious or life-threatening side effects. You should also wait at least 14 days after stopping this medication before taking an MAOI.
• if you have a eye disease called narrow-angle glaucoma (increased pressure in your eye).
• if you have serious heart problems that may worsen with an increase in heart rate and/or blood pressure, as this may be an effect of Atamax.
• if you have serious problems with the blood vessels in your brain, such as a stroke, inflammation, and weakening of part of a blood vessel (aneurysm) or narrowed or blocked blood vessels.
• if you have a tumor in your adrenal gland (pheochromocytoma).

Do not take Atamax if any of the above cases apply to you. If you are not sure, consult your doctor or pharmacist before taking this medication. The reason is that this medication may make these problems worse.

Warnings and precautions

Both adults and children should be aware of the following warnings and precautions. Consult your doctor or pharmacist before starting to take Atamax if you have:

• Serotonin syndrome

Serotonin syndrome is a potentially life-threatening situation that can occur when taking Atamax in combination with other medications (see section 2 "Other medications and Atamax"). The signs and symptoms of serotonin syndrome may include a combination of the following: confusion, restlessness, lack of coordination and stiffness, hallucinations, coma, rapid heartbeat, increased body temperature, rapid changes in blood pressure, sweating, flushing, tremors, hyperactive reflexes, nausea, vomiting, and diarrhea. Contact a doctor or go immediately to the emergency department of the nearest hospital if you think you are experiencing serotonin syndrome.

• Treatment with Atamax may make you feel aggressive, hostile, or violent; or worsen these symptoms if they were present before treatment. It may also cause unusual changes in your behavior or mood (including physical aggression, threatening behavior, and thoughts of harming others). If you or your family and/or friends notice any of these reactions, talk to your doctor or pharmacist immediately.
• suicidal thoughts or attempted suicide.
• heart problems (including heart defects) or an increased heart rate. Atamax may increase your heart rate (pulse). There have been reports of sudden death in patients with heart defects.
• high blood pressure. Atamax may increase your blood pressure.
• low blood pressure. Atamax may cause dizziness or fainting in people with low blood pressure.
• problems with sudden changes in your blood pressure or heart rate.
• cardiovascular disease or a history of having suffered a stroke (cerebrovascular accident).
• liver problems. You may need a lower dose.
• psychotic symptoms, including hallucinations (hearing voices or seeing unreal things), believing things that are not true, or being suspicious.
• mania (feeling elated or overexcited, which causes unusual behavior) and agitation.
• aggression.
• feeling of dislike and anger (hostility).
• history of epilepsy or if you have had seizures for any other reason. Atamax may cause an increase in the frequency of seizures.
• mood changes or feelings of unhappiness.
• repeated spasms of difficult-to-control parts of the body or repetition of sounds and words.

Consult your doctor or pharmacist if you have any of the symptoms mentioned above before starting treatment. The reason is that Atamax may make these problems worse. Your doctor will want to monitor how the medication affects you.
