Strattera (Atomoxetine) – Patient Guide (Australia)

Strattera is a medicine used to treat attention-related symptoms in certain people, particularly Attention-Deficit/Hyperactivity Disorder (ADHD). This guide explains what atomoxetine does, how it works, how to take it safely, what to expect, and important interactions and safety information. It is written to be patient-friendly and for general information only.

Key Product Information

How Strattera Works (Mechanism of Action)

Atomoxetine affects brain chemicals that help regulate attention and impulse control. It is a selective norepinephrine reuptake inhibitor:

• Increases norepinephrine activity by blocking its reuptake into nerve cells.
• Norepinephrine is involved in focus, alertness, and behavioural regulation.
• Because it targets norepinephrine signalling, atomoxetine can help reduce symptoms of ADHD such as inattention, distractibility, and impulsivity.

Strattera is not a stimulant. Many people notice different onset and effects compared with stimulant medicines.

Pharmacokinetics (How Your Body Handles It)

Pharmacokinetics describes how the body absorbs, distributes, metabolises, and eliminates a medicine.

• Absorption: Atomoxetine is absorbed after oral dosing. Peak blood levels typically occur within several hours (commonly around 1–2 hours, depending on the person and formulation).
• Distribution: It distributes through the body and reaches the brain where it can affect neurotransmission.
• Metabolism: Atomoxetine is primarily metabolised by the liver enzyme CYP2D6.
• Elimination: Metabolites are excreted mainly via the urine.
• Half-life: The time for the body to eliminate half of the drug can vary widely among individuals. People who are “poor metabolisers” of CYP2D6 may have higher levels for longer.

Why CYP2D6 matters: Some medicines can inhibit or affect CYP2D6, which may increase atomoxetine levels and side effects.

What Strattera Is Used For (Indications)

In Australia, atomoxetine is used to treat ADHD. It may be considered when:

• Symptoms of inattention, hyperactivity, and impulsivity significantly affect daily functioning.
• A non-stimulant option is preferred or more suitable for the individual.
• Stimulant medicines may not be appropriate due to tolerability, risk factors, or other clinical considerations.

ADHD treatment plans are usually personalised and may include behavioural strategies and educational support alongside medication.

When and How to Take Strattera (Timing and Administration)

Strattera is taken by mouth, usually once daily or twice daily depending on the prescribed regimen and age.

Typical timing

• Once-daily dosing: Often taken in the morning to reduce the chance of sleep disturbance, though your clinician may recommend evening dosing in some circumstances.
• Twice-daily dosing: Doses are usually spaced morning and late afternoon/evening.

Consistency matters

• Try to take it at the same time(s) each day.
• If you miss a dose, follow the instructions provided by your prescriber and medicine label. Avoid taking extra doses to “catch up” unless advised.

How soon you may notice effects

Atomoxetine may take longer than some stimulant medicines. Some people notice early changes, but it often takes several weeks to achieve the full benefit. Plan for a gradual assessment of response.

Dosing Information (General Guidance)

Dose varies by age, body weight, and response/tolerability. Below is general information commonly used to describe initial and maintenance dosing approaches.

• Children and adolescents: Dose is typically started at a lower level and increased gradually to reduce side effects and improve tolerability.
• Adults: Similar stepwise titration may be used, tailored to clinical response.
• CYP2D6 poor metabolisers: May experience higher drug levels for longer and may need dose adjustments.
• Liver impairment: May require adjustments; atomoxetine is generally used cautiously in liver disease.

Important: Always use the dose that appears on your medicine label and follow the schedule given by your healthcare professional. The exact starting dose and maximum dose depend on individual factors.

Food Interactions and Administration With Meals

Atomoxetine can be taken with or without food. However, food may affect absorption for some people.

• If you experience stomach upset, consider taking it with food.
• Try to remain consistent with your routine (e.g., always with breakfast or always on an empty stomach) unless advised otherwise.

Tip: If you have nausea, taking atomoxetine with a light meal may help. If nausea persists, speak with your clinician.

Alcohol and Medicine Interactions

Alcohol

• There is no universal rule that alcohol must be avoided, but alcohol may worsen side effects such as dizziness, drowsiness, mood changes, or impaired concentration.
• If you choose to drink alcohol, do so cautiously and in moderation, and be alert to how you feel.

Interactions with other medicines

Because atomoxetine is metabolised mainly by CYP2D6, medicines that inhibit this enzyme can raise atomoxetine concentrations.

Tell your healthcare professional about all medicines you take, including:

• Prescription medicines
• Over-the-counter products (e.g., cough/cold medicines)
• Herbal supplements (e.g., some preparations may affect CYP enzymes)
• Any recreational substances

Notable interaction categories may include:

• CYP2D6 inhibitors (examples include some antidepressants and antipsychotics): may increase atomoxetine exposure and side effects.
• Medicines affecting blood pressure or heart rate: atomoxetine can influence heart rate and blood pressure in some people.
• Medications affecting mood or anxiety: because ADHD symptoms and mental health can overlap, your treatment plan should consider mood changes.
• Medicines that prolong the QT interval (in some cases): some ADHD medicines can be relevant to heart rhythm risk—your clinician will consider your individual risk factors.

If you are unsure whether a medicine might interact, ask your pharmacist. This is especially important if you take medications for depression, anxiety, migraine, or infections.

Safety Profile: Common, Serious, and When to Seek Help

Like all medicines, atomoxetine can cause side effects. Many people experience mild effects early, which may improve as the body adjusts. However, some symptoms require prompt medical attention.

Common side effects

• Stomach-related: nausea, abdominal discomfort, reduced appetite
• Sleep changes: sleep disturbance (insomnia) or sleepiness
• Headache
• Dizziness
• Dry mouth
• Mood or behaviour changes in some individuals (monitor closely)

Less common but important effects

• Increases in heart rate and blood pressure (your clinician may monitor these)
• Allergic reactions (e.g., swelling, rash, breathing difficulties)
• Sexual side effects can occur with norepinephrine-targeting medicines (varies by individual)
• Liver problems (rare, but important)

Seek urgent medical help if you develop

• Signs of serious allergic reaction: swelling of face/lips, trouble breathing, widespread rash
• Symptoms suggestive of liver injury: yellowing of the skin/eyes, dark urine, severe fatigue, upper right abdominal pain, persistent vomiting
• Severe or persistent fainting or chest pain
• New or worsening thoughts of self-harm or severe agitation (urgent assessment is needed)
• Seizures or severe neurological symptoms

Monitoring during treatment

Your healthcare team may check:

• Blood pressure and pulse periodically
• Weight and appetite, especially in children and adolescents
• Sleep patterns and daytime functioning
• Emotional wellbeing and behaviour changes

Practical Use Tips for Better Results

• Give it time: Atomoxetine benefits may build gradually. Don’t judge effectiveness after only a few days.
• Use a routine: Tie the dose to a consistent daily habit (breakfast or morning routine) to improve adherence.
• Track symptoms: Many people find it helpful to note attention, impulsivity, school/work performance, and sleep to discuss progress with their clinician.
• Manage appetite: If appetite drops, plan nutrient-dense meals and speak to your clinician if weight loss occurs.
• Watch sleep: If you feel wired or can’t sleep, avoid late dosing (unless your clinician recommends otherwise) and discuss timing changes.
• Be cautious with driving: If dizziness or drowsiness occurs, avoid driving or operating machinery until you know how you respond.

What to Do If You Miss a Dose

If you miss a dose, the best action depends on your schedule and how close it is to the next dose. In general:

• Do not double up unless your clinician or pharmacist instructs you to.
• Follow the guidance on your medicine label or the advice from your pharmacy.

If you’re uncertain, contact a pharmacist for advice specific to your regimen.

Alternative Options for ADHD

ADHD management is individual. Options may include medication, behavioural interventions, school or workplace support, and therapy. Alternatives to atomoxetine may include:

Non-medicinal/supportive approaches

• Behavioural strategies and parent/teacher training
• Coaching and organisational skills support
• School accommodations and structured routines
• Psychological therapies targeting coping skills and self-regulation

Medication alternatives

• Stimulant medicines (commonly used in ADHD): often have faster onset but may be unsuitable for some people due to side effects or risk factors.
• Other non-stimulant options: some people may be suitable for different non-stimulant medication strategies depending on local availability and clinical criteria.

Your healthcare professional can help compare benefits, onset, side effects, and long-term considerations to decide what’s best for you.
