Strattera (Atomoxetine) — Patient Guide (Australia)

Strattera® contains atomoxetine, a medicine used to treat attention deficit/hyperactivity disorder (ADHD). This guide explains how Strattera works, how it’s taken, food and alcohol considerations, possible side effects, and practical tips to help you use the medicine safely and effectively in Australia.

Note: Individual needs vary. Always follow the instructions provided by your healthcare professional and the product information for your specific brand and dose.

Quick overview

• Medicine: Strattera (atomoxetine)
• Common use: ADHD in children, adolescents, and adults
• How it works: Selectively increases noradrenaline (norepinephrine) activity in the brain
• Form: Capsules in different strengths (brand presentation may vary)
• Onset: Some benefits may appear within 1–2 weeks; full effects may take several weeks
• Key precautions: Liver injury risk (rare), mood changes, suicidal thoughts in some people under 25, blood pressure/heart rate changes, sedation and fatigue

Basic product information

Strattera (atomoxetine) is an ADHD medicine that is taken by mouth. Unlike some ADHD medicines that are stimulants, atomoxetine is a non-stimulant option.

What is ADHD and how Strattera helps

ADHD is a neurodevelopmental condition that can involve ongoing difficulties with attention, impulsivity, and/or hyperactivity. Treatment may help improve everyday functioning, such as:

• Focusing on tasks and reducing distractibility
• Improving organisation and follow-through
• Reducing impulsive behaviour
• Managing restlessness and agitation

Strattera is designed to target core symptoms rather than only providing short-term calming effects.

Mechanism of action (how it works)

Atomoxetine works primarily by affecting noradrenaline (norepinephrine) signalling in the brain and spinal cord. It acts as a selective inhibitor of the norepinephrine transporter, increasing the amount of noradrenaline available in the synaptic cleft.

This helps improve the balance of neurotransmitters involved in attention, impulse control, and executive functioning. Importantly, atomoxetine is not a stimulant and does not produce the typical stimulant “rush” associated with some other ADHD medicines.

Pharmacokinetics (how the body processes it)

Understanding pharmacokinetics can help explain why timing and consistent use matter.

• Absorption: Atomoxetine is absorbed after oral dosing. Food may influence how quickly it reaches peak levels for some people.
• Peak concentration (Tmax): The time to reach maximum concentration varies, often occurring within a few hours after a dose.
• Metabolism: Atomoxetine is mainly metabolised in the liver by CYP2D6. People who have slower or faster CYP2D6 metabolism may experience different exposure and effects.
• Elimination: Metabolites are cleared primarily via the kidneys. The overall clearance supports once-daily (or split) dosing schedules.
• Steady state: With regular dosing, atomoxetine concentrations gradually stabilise. It can take days to weeks for the full effect to be apparent.

Practical implication: Consistent daily dosing is important. If doses are missed repeatedly, symptom control may be less predictable.

Typical use and who it’s for

Strattera is used for ADHD symptoms in:

• Children (generally school-age and older, as determined by local prescribing guidance)
• Adolescents
• Adults

It may be considered when:

• A non-stimulant option is preferred
• Stimulant medicines are not suitable or are not well tolerated
• Longer-term, steady symptom control is desired
• There is a need to avoid stimulant-related side effects in some individuals

When to take it: timing and how long it takes to work

Strattera is usually taken once daily or split into two doses depending on the total daily dose and your response.

Starting and ramp-up

• Many people begin at a lower dose and gradually increase to help reduce side effects.
• Do not change the dose yourself.

Onset of benefit

• Early changes: Some people notice improvements within 1–2 weeks.
• Full benefit: May take several weeks (often up to 6–12 weeks in clinical practice) for optimal symptom control.

Time of day

The best time depends on your side effects and sleep. In general:

• If Strattera makes you feel sleepy or fatigued, consider taking it earlier in the day.
• If it feels activating, your clinician may recommend morning dosing (or dividing the dose).

Food interactions and swallowing tips

Strattera can be taken with or without food. However, food may affect the speed at which atomoxetine reaches its peak blood level.

• For consistency, take Strattera the same way each day (either always with food or always without) unless your clinician advises otherwise.
• Swallow capsules whole with water. Do not open or chew unless specifically directed by the product instructions.

Gastrointestinal effects: Some people experience nausea, stomach upset, or reduced appetite. Taking the dose with a light meal may help.

Alcohol and medicine interactions

Alcohol

It’s best to be cautious with alcohol. While there is no single “safe” amount that applies to everyone, alcohol may:

• Worsen dizziness, drowsiness, or impaired concentration
• Increase mood and sleep disturbances
• Make side effects feel stronger

If you plan to drink alcohol, consider how you respond to atomoxetine on typical days and avoid heavy drinking.

Common medicine interactions

Atomoxetine is metabolised by CYP2D6. Medicines that inhibit or strongly affect CYP2D6 can increase atomoxetine levels and side effects.

Important interaction categories include:

• CYP2D6 inhibitors (may raise atomoxetine exposure). Examples can include some antidepressants and certain other medicines—your pharmacist can check your specific list.
• Other ADHD medicines: combining therapies should be supervised by a clinician.
• Blood pressure and heart-rate medicines: atomoxetine can influence cardiovascular parameters, so monitoring may be needed.
• Medicines that affect mood: if you’re taking antidepressants or other psychiatric medicines, ensure your clinician knows the full list.
• Drugs affecting clotting or bleeding: while not a direct common interaction, discuss any medicines that increase bleeding risk (e.g., some antiplatelet/anticoagulant therapies).

Always tell your healthcare professional about:

• Prescription medicines
• Over-the-counter medicines
• Herbal products (e.g., St John’s wort)
• Supplements

Indications (what Strattera is used for)

In Australia, Strattera is indicated for the treatment of ADHD in:

• Children and adolescents
• Adults

It may be used as part of a broader care plan that may include behavioural strategies, educational support, and counselling.

Dosing: typical approach and practical guidance

Dose selection is individualised based on body weight (for children and adolescents), response, and tolerability.

General dosing principles

• Start low, go slow: many patients begin with a lower dose to improve tolerability.
• Titrate to effect: the dose may be increased gradually over time.
• Consider metabolism: CYP2D6 differences and interacting medicines can affect exposure.
• Long-term use: ADHD medicines are often continued while benefits outweigh risks.

Typical adult dosing pattern (overview)

Adults often start on a standard initial dose, then may be increased to a target daily dose depending on response. Your clinician will specify your exact dose schedule.

Typical child/adolescent dosing pattern (overview)

For children and adolescents, dosing is commonly based on body weight and adjusted gradually. Your clinician will calculate a target range for your child’s situation.

Taking missed doses

• If you miss a dose, take it as soon as you remember unless it’s close to the next dose.
• Do not take double to make up for a missed dose.
• If you’re unsure, contact your pharmacist or clinician for advice.

Stopping Strattera

Do not stop suddenly without medical advice. Your clinician can guide how to taper if needed and monitor for symptom changes.

Important: This page provides general educational information. For your exact dose and regimen, follow the dosing instructions provided to you.

Safety profile: side effects and when to seek help

Like all medicines, Strattera can cause side effects. Many are mild and improve over time, but some require urgent medical attention.

Common side effects

• Nausea or stomach upset
• Reduced appetite
• Dry mouth
• Sleep changes (insomnia or sleepiness)
• Fatigue or tiredness
• Dizziness
• Headache
• Increased heart rate or blood pressure (usually mild, but monitored)
• Mood changes in some people (e.g., irritability)

Less common but important risks

• Suicidal thoughts (warning in some age groups): any new or worsening depression, unusual behaviour changes, or thoughts of self-harm should be treated seriously and promptly assessed.
• Liver injury (rare): watch for signs such as jaundice (yellow skin/eyes), dark urine, severe fatigue, itching, or upper abdominal pain.
• Allergic reactions: rash, swelling, trouble breathing.
• Cardiovascular effects: fainting, chest pain, significant palpitations, or persistent fast heart rate.
• Blood vessel/skin effects (rare): severe or persistent skin reactions should be evaluated urgently.
• Urinary retention (rare): difficulty urinating or inability to urinate.
• Mania/hypomania (risk in people with bipolar disorder): watch for elevated mood, decreased need for sleep, racing thoughts, or risky behaviour.

When to seek urgent medical help

Get urgent assistance if you or your child experiences:

• Thoughts of self-harm, suicidal thoughts, or sudden severe mood changes
• Signs of liver problems (yellowing of eyes/skin, dark urine)
• Severe allergic reactions (swelling of face/lips, difficulty breathing)
• Chest pain, fainting, severe palpitations, or shortness of breath
• Severe skin rash or blistering

For Australia, in emergencies call 000. If you need immediate psychiatric support, you can also contact Lifeline 13 11 14 or 1800RESPECT as appropriate.

Practical use tips for better results

• Be consistent: take Strattera at the same time each day to maintain steady effects.
• Give it time: benefits often build gradually. Avoid stopping early if you don’t feel immediate effects—unless side effects are severe.
• Track symptoms: consider a brief daily note of attention, impulsivity, sleep, and appetite to discuss progress with your clinician.
• Manage nausea: taking with food and drinking water may help. Report persistent nausea.
• Support appetite: monitor weight and growth in children and adolescents; smaller, nutrient-dense meals may help if appetite drops.
• Sleep hygiene: if insomnia occurs, avoid caffeine late in the day and discuss dosing time changes with your healthcare professional.
• Check blood pressure and heart rate: your clinician may monitor these periodically, especially during dose changes.
• Don’t mix medications casually: talk to your pharmacist before adding new prescriptions, over-the-counter products, or supplements.

Alternative options for ADHD (non-Strattera choices)

There are several ADHD treatment options. The “best” approach depends on symptom profile, age, medical history, side effect preferences, and response to previous treatments.

Non-stimulant alternatives

• Guanfacine (selected formulations, depending on local availability and age group)
• Clonidine (off-label considerations may apply in some cases—discuss with clinician)

Stimulant options

• Methylphenidate (various preparations)
• Lisdexamfetamine (where indicated)
• Dexamfetamine and other stimulant medicines

Behavioural and supportive strategies

• Structured routines, timers, and planners
• School-based adjustments and behavioural therapy
• Coaching for organisational skills
• Parent training and behaviour management programs

Many people benefit from combining medication with skills-based support.
