Stalevo (Carbidopa / Entacapone / Entacapone) – Patient Information (Australia)

Stalevo is a combination medicine used to help manage symptoms of Parkinson’s disease. It combines carbidopa with entacapone (present in the product as described in the Stalevo formulation). The medicine works by increasing and prolonging dopamine activity in the brain, helping improve mobility and “wearing-off” symptoms.

This page provides general information about how Stalevo works, how it is typically used, important safety considerations, and practical tips for day-to-day use in Australia. Always follow the instructions provided by your doctor or pharmacist.

Key product information

Note: In Australia, medicine brand names, strengths, and formulation details can vary. Ask your pharmacist to confirm the exact strength you have been supplied.

How Stalevo works (mechanism of action)

Parkinson’s disease is characterised by reduced dopamine activity. Dopamine helps control movement and coordination. Stalevo helps by increasing the availability and duration of dopamine-related effects.

• Carbidopa helps prevent levodopa from being broken down before it reaches the brain. This supports a stronger and more consistent effect on Parkinson’s symptoms.
• Entacapone belongs to a class of medicines called COMT (catechol-O-methyltransferase) inhibitors. Entacapone works by blocking an enzyme that breaks down dopamine (and dopamine precursors) in the body. As a result, dopamine activity lasts longer, reducing “wearing-off” and improving the steadiness of symptom control.

Together, these actions can improve mobility and help maintain symptom relief between doses.

Pharmacokinetics (how the body handles the medicine)

Pharmacokinetics describes how a medicine is absorbed, distributed, metabolised, and eliminated. While individual response varies, the main practical points are:

• Absorption: Stalevo is taken by mouth and is absorbed through the gastrointestinal tract.
• Onset: Symptom improvement is commonly noticed after taking the medicine, though timing varies by person.
• Duration: Entacapone helps extend the effect of dopamine-related therapy, often used to reduce fluctuations.
• Metabolism: Components are metabolised primarily in the liver through multiple pathways.
• Elimination: Metabolites are eliminated mainly through bile and urine.

Some people may experience a delayed or reduced effect when taken with certain foods (see “Food interactions”). Your clinician may adjust dose timing to improve consistency.

What Stalevo is typically used for

Stalevo is used to treat Parkinson’s disease. It is most often used when people experience:

• Wearing-off—symptoms return before the next scheduled dose.
• Fluctuations in mobility (e.g., periods of “on” time and “off” time).

The goal is to provide steadier symptom control and reduce periods of reduced mobility.

Typical timing and dosing approach

Dosing must be individualised. Your pharmacist may provide instructions on how many tablets to take and exactly when to take them. The following information is general guidance.

How it’s usually taken

• Regular schedule: Stalevo is typically taken at set times during the day. Many people take it multiple times daily to maintain symptom control.
• Consistency matters: Taking doses at similar times each day can help stabilise effect.
• Do not change frequency: If your symptoms change, contact your healthcare professional rather than adjusting on your own.

Missed dose

• If you miss a dose, take it when you remember unless it is close to your next dose.
• Do not take a double dose to make up for a missed tablet.
• If you’re unsure, ask your pharmacist for personalised advice.

Important: Stopping or rapidly changing Parkinson’s medicines can worsen symptoms. Seek guidance before making changes.

Food interactions and taking with meals

Some people notice differences in how well the medicine works depending on meals. Food—especially high-protein meals—may affect how dopamine-related medicines are absorbed and utilised.

• High-protein meals: Protein can compete with the transport of certain Parkinson’s medicines. This may reduce effectiveness in some people.
• Timing strategy: Some clinicians recommend taking doses with lighter meals or timing protein intake later in the day. This should be discussed with your healthcare team.
• Nausea: If nausea occurs, taking the dose with a small snack may help (unless your clinician advises otherwise).

For consistent results, aim to follow your usual routine around meals when starting or adjusting Stalevo. If your mobility becomes unpredictable, talk to your pharmacist or doctor.

Alcohol interactions

Alcohol can worsen Parkinson’s symptoms, increase drowsiness, and may affect blood pressure regulation. Entacapone and carbidopa may also cause dizziness or light-headedness in some people. Combining with alcohol may increase these risks.

• Avoid or minimise alcohol where possible.
• If you choose to drink, do so cautiously and monitor for dizziness, falls, or worsening motor symptoms.

Medicine interactions (including common drug classes)

Stalevo can interact with other medicines. Always tell your pharmacist about all medicines you take, including: over-the-counter products, herbal supplements, vitamins, and occasional medicines.

Examples of interactions to discuss

• Antidepressants (especially MAO inhibitors): Some antidepressants can interact with Parkinson’s medicines. Your doctor will advise which combinations are safe.
• Iron supplements: Iron can reduce absorption of some Parkinson’s medicines. Spacing doses may be required.
• Antipsychotic medicines: Some antipsychotics may affect Parkinson’s symptoms or interact with dopamine-related therapies.
• Blood pressure medicines: Parkinson’s medicines may contribute to low blood pressure; combining with antihypertensives may increase dizziness.
• Other medicines that affect the central nervous system: Sleepiness or impairment may be increased with sedatives.
• Antidiarrhoeals or constipation treatments: Gastrointestinal changes may influence symptoms and absorption patterns.

If you start a new medicine (including antibiotics, anti-nausea medicines, or supplements), check whether it may interact with Stalevo.

Indications (when Stalevo is recommended)

In general, Stalevo is indicated for people with Parkinson’s disease who need:

• Levodopa-related symptom management with a more sustained effect.
• Reduction of “wearing-off” between doses, improving mobility and daily function.

Your healthcare team may select Stalevo when it’s expected to improve fluctuation patterns or extend the time you feel “on”.

Safety profile: side effects and warnings

Like all medicines, Stalevo can cause side effects. Not everyone experiences them. Side effects may depend on dose, other medications, and individual health factors.

Common side effects

• Dyskinesia (involuntary movements), especially if the dose is high or therapy is recently adjusted
• Nausea or stomach discomfort
• Diarrhoea (more commonly associated with entacapone-containing medicines)
• Low blood pressure (light-headedness, dizziness when standing)
• Headache
• Urine colour changes—may appear darker (usually benign)

Less common but important risks

• Falling: Dizziness or blood pressure changes may increase fall risk.
• Hallucinations or confusion: Particularly in older adults or in sensitive individuals.
• Sleepiness: Some people may feel unusually drowsy; rarely, sudden sleep onset may occur.
• Worsening of psychiatric symptoms: Mood changes may occur in some people.
• Liver problems: Rarely, serious liver issues can occur. Symptoms might include unusual fatigue, loss of appetite, dark urine, or yellowing of skin/eyes.

Seek urgent help if you experience

• Severe allergic reaction (swelling of face/lips, trouble breathing)
• Chest pain, severe shortness of breath
• Signs of severe dehydration from persistent diarrhoea/vomiting
• Confusion or agitation that is rapidly worsening

Practical use tips (getting the best results)

• Use a reminder system: Tablet times can be critical for steady symptom control. Consider alarms or a medication organiser.
• Track “on/off” times: Keeping a brief daily log can help your clinician fine-tune dosing. Note mobility, tremor, falls, dyskinesia, nausea, and sleepiness.
• Manage diarrhoea early: If diarrhoea occurs, stay hydrated and contact your pharmacist for advice. Do not ignore persistent symptoms.
• Stand up slowly: To reduce dizziness, move slowly when getting up, especially in the morning or after sitting.
• Be cautious with driving or machinery: If you feel drowsy or dizzy, avoid driving and seek medical advice.
• Keep consistent with meals: Sudden changes in meal timing or protein intake may affect symptom control.

Alternative options

Your healthcare team may suggest different strategies depending on your symptoms, fluctuations, and side effect profile. Alternatives can include:

• Other COMT inhibitors (for extending levodopa effect in appropriate patients)
• Other Parkinson’s medications that target dopamine receptors or dopamine metabolism through different mechanisms
• Adjusting levodopa dose or timing rather than adding or changing combinations
• Non-pharmacological supports such as physiotherapy and occupational therapy to improve mobility and balance

The best choice depends on your “wearing-off” pattern, symptom severity, tolerability, and overall health. Discuss options with your pharmacist or neurologist.

Market and legal context in Australia

Medicines in Australia are regulated through the TGA (Therapeutic Goods Administration). Access to Parkinson’s medicines like Stalevo is provided through Australia’s established medicines supply and clinical governance systems. Your clinician determines which medicine is suitable for you based on diagnosis and individual factors.

Supply can vary due to manufacturing schedules and logistics. Your pharmacist can help confirm availability and, if needed, suggest equivalent options (such as switching strengths or temporary alternatives).

Important: Always check the package label and any patient information provided with your specific product.

Recent guidance and best-practice considerations

Australian clinicians commonly review Parkinson’s therapy using a balance of:

• Symptom control (mobility, tremor, stiffness)
• Fluctuation management (reducing “off” time and wearing-off)
• Side effects (dyskinesia, hallucinations, blood pressure changes, gastrointestinal issues)
• Medication timing and nutrition factors (particularly protein distribution)

If you experience significant fluctuations, falls, hallucinations, or persistent diarrhoea, your treatment plan may need review. Guidance may also include advice on monitoring and dose adjustment to minimise adverse effects while maintaining function.
