Atomoxetine Capsules contain atomoxetine and are used to treat attention-deficit and hyperactivity disorder (ADHD). It is used

• in children over six years of age
• in young people
• in adults.

It is used only as a part of the total treatment of the disease which also requires treatments which do not involve medicines, such as counselling and behavioural therapy.

It is not for use as a treatment for ADHD in children under 6 years of age as it is not known if the drug works or is safe in these people.

In adults, Atomoxetine is used to treat ADHD when the symptoms are very troublesome and affect your work or social life and when you have had symptoms of the disease as a child.

Atomoxetine increases the amount of noradrenaline in the brain. This is a chemical that is produced naturally, and increases attention and decreases impulsiveness and hyperactivity in patients with ADHD. This medicine has been prescribed to help control the symptoms of ADHD. This medicine is not a stimulant and is therefore not addictive. It may take a few weeks after you start the medicine for your symptoms to fully improve.

Children and young people with ADHD find it:

• hard to sit still and
• hard to concentrate.

It is not their fault that they cannot do these things. Many children and young people struggle to do these things. However, with ADHD this can cause problems with everyday life. Children and young people with ADHD may have difficulty learning and doing homework. They find it hard to behave well at home, at school or in other places. ADHD does not affect the intelligence of a child or young person.

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

• work
• relationships
• low self esteem
• education.

• are allergic to atomoxetine or any of the other ingredients of this medicine (listed in section 6)
• took a medicine known as a monoamine oxidase inhibitor (MAOI), for example phenelzine, in the last two weeks. An MAOI is sometimes used for depression and other mental-health problems; taking Atomoxetine with an MAOI could cause serious side effects or be life-threatening. You also need to wait at least 14 days after you stop taking Atomoxetine before you take an MAOI
• have an eye disease called narrow-angle glaucoma (increased pressure in your eye)
• have serious problems with your heart which may be affected by an increase in heart rate and/or blood pressure, as this may be an effect of Atomoxetine
• have serious problems with the blood vessels in your brain - such as a stroke, swelling and weakening of part of a blood vessel (aneurysm) or narrow or blocked blood vessels
• have a tumour of your adrenal gland (phaeochromocytoma).

Do not take Atomoxetine if any of the above applies to you. If you are not sure, talk to your doctor or pharmacist before you take Atomoxetine. This is because Atomoxetine can make these problems worse.

Both adult and children should be aware of the following warnings and precautions. Talk to your doctor or pharmacist before taking Atomoxetine if you have:

• thoughts about killing yourself or trying to kill yourself
• problems with your heart (including heart defects) or an increased heartbeat. Atomoxetine can increase your heart rate (pulse). Sudden death has been reported in patients with heart defects
• high blood pressure. Atomoxetine can increase blood pressure
• low blood pressure. Atomoxetine can cause dizziness or fainting in people with low blood pressure
• problems with sudden changes in your blood pressure or your heart rate
• cardiovascular disease or past medical history of stroke
• liver problems. You may need a lower dose
• psychotic symptoms including hallucinations (hearing voices or seeing things which are not there), believing things that are not true or being suspicious
• mania (feeling elated or over-excited, which causes unusual behaviour) and agitation
• aggressive feelings
• unfriendly and angry (hostility) feelings
• a history of epilepsy or have had seizures for any other reason. Atomoxetine might lead to an increase in seizure frequency
• different moods than usual (mood swings) or feel very unhappy
• hard-to-control, repeated twitching of any parts of the body or you repeat sounds and words.

Serotonin syndrome

Serotonin syndrome is a potentially life-threatening condition which may occur when taking Atomoxetine in combination with some other medicines (see section 2 “Other medicines and Atomoxetine”). Signs and symptoms of serotonin syndrome may include a combination of the following: confusion, restlessness, incoordination and rigidity, hallucinations, coma, fast heart beat, increased body temperature, fast changes in blood pressure, sweating, flushing, tremor, overactive reflexes, nausea, vomiting, and diarrhoea. Contact a doctor or go to your nearest emergency department immediately if you think serotonin syndrome is happening to you.

Treatment with Atomoxetine may make you feel aggressive, hostile or violent; or aggravate these symptoms if they were present before treatment. It may also cause you to have unusual changes in behaviour or mood (including physical assault, threatening behaviour and thoughts of harming others). If you or your family and/or friends notice any of these reactions, talk to your doctor or pharmacist right away.

Tell your doctor or pharmacist if any of the above applies to you before starting treatment. This is because Atomoxetine can make these problems worse. Your doctor will want to monitor how the medicine affects you.

These checks are to decide if Atomoxetine is the correct medicine for you.

Your doctor will measure your

• blood pressure and your heart rate (pulse) before and during the time you take Atomoxetine
• your height and weight if you are a child or teenager during the time you take Atomoxetine.

Your doctor will talk to you about:

• any other medicines you are taking
• whether there is any family history of sudden unexplained death
• any other medical problems (such as heart problems) you or your family may have.

It is important that you provide as much information as you can. This will help your doctor decide if Atomoxetine is the correct medicine for you. Your doctor may decide that other medical tests are needed before you start taking this medicine.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes non-prescription medicines. Your doctor will decide if you can take Atomoxetine with your other medicines and in some cases your doctor may need to adjust your dose or increase your dose much more slowly.

Do not take Atomoxetine with medicines called MAOIs (monoamine oxidase inhibitors) used for depression. See section 2 “Do not take Atomoxetine”.

If you are taking other medicines, Atomoxetine may affect how well they work or may cause side effects. If you are taking any of the following medicines, check with your doctor or pharmacist before taking Atomoxetine:

• medicines that increase blood pressure or are used to control blood pressure
• medicines such as antidepressants, for example imipramine, venlafaxine, mirtazapine, fluoxetine and paroxetine
• some cough and cold remedies which contain medicines that can affect blood pressure. It is important to check with your pharmacist when you get any of these products
• some medicines used to treat mental health conditions
• medicines that are known to increase the risk of seizures
• some medicines that cause Atomoxetine to stay in the body for longer than normal (such as quinidine and terbinafine)
• salbutamol (a medicine to treat asthma) when taken by mouth or injected may make you feel as if your heart is racing, but this will not make your asthma worse.

Atomoxetine may affect or be affected by other medicines. These include:

• some antidepressants, opioids as tramadol, and medicines used to treat migraine called triptans. These medicines may interact with Atomoxetine and can lead to serotonin syndrome, a potentially life-threatening condition. (See section 2, Warnings and Precautions, Serotonin Syndrome).

The medicines below may lead to an increased risk of an abnormal rhythm of the heart when taken with Atomoxetine:

• medicines used to control the rhythm of the heart
• medicines which change the concentration of salts in the blood
• medicines for malaria prevention and treatment
• some antibiotic medicines (such as erythromycin and moxifloxacin).

If you are not sure about whether any medicines you are taking are included in the list above, ask your doctor or pharmacist before taking Atomoxetine.

It is not known if this medicine can affect an unborn baby or pass into breast milk.

• This medicine should not be used during pregnancy, unless your doctor has advised you to do so.
• You should either avoid taking this medicine if you are breastfeeding or discontinue breastfeeding.

If you are:

• pregnant or breastfeeding
• thinking that you may be pregnant or are planning to have a baby
• planning to breastfeed your baby

ask your doctor or pharmacist for advice before taking this medicine.

You may feel tired, sleepy or dizzy after taking Atomoxetine. You should be careful if you are driving a car or operating machinery until you know how Atomoxetine affects you. If you feel tired, sleepy or dizzy you should not drive or operate machinery.

Do not open Atomoxetine capsules because the contents of the capsule can irritate the eye. If the contents of the capsules come into contact with the eye, the affected eye should be flushed immediately with water, and medical advice obtained. Hands and any other part of the body that may have come into contact with the capsule contents should also be washed as soon as possible.

If you are a child or teenager (6 years or older):

Your doctor will tell you how much Atomoxetine you should take and will calculate this according to your weight. He/she will normally start you on a lower dose before increasing the amount of Atomoxetine you need to take according to your body weight.

• Body weight up to 70 kg: a starting total daily dose of 0.5 mg per kg of body weight for a minimum of 7 days. Your doctor may then decide to increase this to the usual maintenance dose of about 1.2 mg per kg of body weight daily.
• Body weight over 70 kg: a starting total daily dose of 40 mg for a minimum of 7 days. Your doctor may then decide to increase this to the usual maintenance dose of 80 mg daily. The maximum daily dose your doctor will prescribe is 100 mg.

Adults

• Atomoxetine should be started at a total daily dose of 40 mg for a minimum of 7 days. Your doctor may then decide to increase this to the usual maintenance dose of 80 mg-100 mg daily. The maximum daily dose your doctor will prescribe is 100 mg.

If you have problems with your liver your doctor may prescribe a lower dose.

If you take more Atomoxetine than you should contact your doctor or the nearest hospital casualty department immediately and tell them how many capsules you have taken. The most commonly reported symptoms accompanying overdoses are gastrointestinal symptoms, sleepiness, dizziness, tremor, and abnormal behaviour. Very rarely, serotonin syndrome has also been reported, a potentially life-threatening condition. (See section 2, Warnings and precautions, Serotonin Syndrome).

If you miss a dose, you should take it as soon as possible, but you should not take more than your total daily dose in any 24-hour period. Do not take a double dose to make up for a forgotten dose.

If you stop taking Atomoxetine there are usually no side effects but your ADHD symptoms may return. You should talk to your doctor first before you stop treatment.

Your doctor will do some tests

• before you start - to make sure that Atomoxetine is safe and will be of benefit
• after you start - they will be done at least every 6 months, but possibly more often.

They will also be done when the dose is changed. These tests will include:

• measuring height and weight in children and young people
• measuring blood pressure and heart rate
• checking whether you have any problems or if side effects have got worse while taking Atomoxetine.

Atomoxetine does not need to be taken for ever. If you take Atomoxetine for more than a year, your doctor will review your treatment, to see if the medicine is still needed.
