Stalevo (Carbidopa / Entacapone / Levodopa) — Patient Information (Australia)

Stalevo is a combination medicine used to treat the symptoms of Parkinson’s disease. It contains three active ingredients: carbidopa, levodopa, and entacapone. Together, these medicines help reduce “off” periods (when Parkinson’s symptoms return) and improve mobility and quality of life.

This page explains what Stalevo is, how it works, how it’s taken, common interactions, safety considerations, and practical tips for day-to-day use. It also includes information relevant to people in Australia, including availability and typical regulatory considerations.

Key product information

Note: Strengths and dosing schedules can differ between available products. Always follow the dosing instructions provided with your medicine and your healthcare professional’s plan.

What Parkinson’s disease symptoms are treated?

Stalevo is used to help manage motor symptoms of Parkinson’s disease, including:

• Tremor
• Stiffness
• Slowness of movement (bradykinesia)
• Difficulty walking and reduced mobility
• “Wearing off” or off periods between levodopa doses

How Stalevo works (mechanism of action)

Stalevo combines three complementary actions:

• Levodopa enters the brain and is converted to dopamine, helping restore dopamine activity that is reduced in Parkinson’s disease.
• Carbidopa blocks the breakdown of levodopa in the body outside the brain. This means more levodopa reaches the brain and also reduces certain side effects related to peripheral levodopa.
• Entacapone inhibits catechol-O-methyltransferase (COMT), an enzyme that breaks down levodopa. By slowing levodopa breakdown, entacapone can help extend the effect of each levodopa dose and reduce fluctuations.

In simple terms: Stalevo helps your body use levodopa more effectively and for longer, improving symptom control throughout the day.

Pharmacokinetics (how the body processes the ingredients)

Pharmacokinetics describes how the medicine is absorbed, distributed, metabolised, and eliminated.

• Levodopa: Absorption can be affected by factors such as food (especially protein content). After reaching the bloodstream, levodopa is distributed throughout the body and converted to dopamine mainly in the brain.
• Carbidopa: Carbidopa helps reduce peripheral metabolism of levodopa, improving the amount of levodopa available to reach the brain.
• Entacapone: Entacapone is designed to reduce COMT-mediated breakdown of levodopa, prolonging levodopa’s effects.
• Metabolism & elimination: Both entacapone and its metabolites are cleared primarily through metabolism and then elimination via the biliary/faecal route (and to a lesser extent via the kidneys, depending on metabolite handling).

Practical implication: Because these ingredients influence how long levodopa works, timing matters. Consistent scheduling helps reduce “off” periods and improve predictability of symptom relief.

Typical use and when it’s taken

Stalevo is typically used in people with Parkinson’s disease who require regular levodopa therapy and may experience motor fluctuations (such as “off” periods). It may be used:

• To improve symptom control over the day
• To reduce wearing-off effects between doses
• As part of a broader Parkinson’s treatment plan (which may include other medicines)

Timing guidance (general)

Because Parkinson’s medicines are often tailored to an individual’s symptoms, dosing schedules vary. However, practical timing principles include:

• Take doses at consistent times to reduce fluctuations.
• Try to keep the interval between doses as recommended by your healthcare professional.
• If you miss a dose, follow the instructions provided with your medicine. If you are unsure, ask a healthcare professional.

How to take Stalevo

Follow the instructions on the dispensing label or as directed by your healthcare professional.

• Swallow tablets whole with water (unless instructed otherwise).
• Take at the times indicated on your medication plan.
• If you have swallowing difficulties, ask your pharmacist about formulation-specific options.

Do you need to take with food?

Many people experience better predictability when levodopa combinations are taken with consistent meal patterns. However, the key dietary factor is protein (see the food interaction section below).

Food interactions (especially protein)

Food can influence how much levodopa is absorbed. The most important dietary interaction relates to protein-rich meals.

Protein effects

• High-protein meals (meat, dairy, eggs, legumes, protein shakes) can reduce levodopa absorption in some people.
• This may make symptoms feel less controlled at certain times of day, particularly around large or high-protein meals.

Practical strategies

• Be consistent with meal timing and protein intake patterns.
• Some people benefit from taking doses away from the largest protein meal. Discuss a tailored plan with your healthcare professional or dietitian.
• Do not drastically change diet without medical advice.

Alcohol and medicine interactions

Because Parkinson’s disease and its treatment affect the nervous system, alcohol may increase risks such as dizziness and falls.

Alcohol

• Limit or avoid alcohol unless your healthcare professional advises otherwise.
• If you drink alcohol, monitor for increased sleepiness, light-headedness, or worsening balance.

Other important medicine interactions

Stalevo interacts with several medicine classes. Tell your healthcare professional or pharmacist about all medicines you take, including over-the-counter products and supplements.

• Non-selective MAO inhibitors (and some MAO-A inhibitors): may require careful avoidance or special timing due to risk of interactions.
• Antipsychotics that block dopamine receptors: some may worsen Parkinson’s symptoms.
• Antidepressants and certain mood-stabilising medicines: may require monitoring depending on the specific drug.
• Iron supplements: excessive iron can reduce effectiveness of some Parkinson medications if taken simultaneously.
• Antihypertensives: if you experience low blood pressure, combined effects may increase dizziness.
• Medicines causing sedation: may add to sleepiness or increase risk of drowsiness-related accidents.

Tip: Ask your pharmacist to check for interactions when starting, stopping, or changing any medicine.

Indications (who Stalevo is for)

Stalevo is indicated for the management of Parkinson’s disease, particularly in situations where:

• Levodopa therapy is needed
• There are motor fluctuations or “wearing off” periods
• A combination of carbidopa and entacapone with levodopa is appropriate

Not everyone with Parkinson’s disease will be suitable for Stalevo. Suitability depends on your symptom pattern, other medicines, medical history, kidney/liver function, and tolerance of side effects.

Dosing (general information)

Dose requirements vary based on age, symptom severity, current levodopa regimen, and response to treatment. Your healthcare professional will determine the most appropriate dose and schedule.

Starting and adjustments

• Dosing is often started at a lower dose and adjusted gradually.
• If switching from other levodopa/entacapone regimens, the dose may need careful calculation to maintain symptom control and minimise side effects.
• Do not change your dose or dosing schedule without medical guidance.

Missed dose guidance

• Take the missed dose only if it is close enough to the next scheduled dose to avoid doubling.
• If you are close to the next dose, skip the missed dose and continue your normal schedule.
• If you are unsure, contact a pharmacist or healthcare professional.

Because product strengths vary, always check the exact tablet strength on your packaging and confirm the timing with your medication plan.

Safety profile (what to watch for)

Like all medicines, Stalevo can cause side effects. Many are manageable, especially with gradual dose changes and careful monitoring. However, some symptoms require prompt medical attention.

Common side effects

• Nausea or indigestion
• Dizziness or light-headedness
• Dry mouth
• Loss of appetite
• Abnormal involuntary movements (dyskinesia), especially at higher doses
• Headache
• Diarrhoea (entacapone may contribute)
• Constipation or changes in bowel habits

Important and potentially serious risks

• Low blood pressure (orthostatic hypotension): Feeling faint when standing can increase fall risk.
• Hallucinations or confusion: more likely in older individuals or with high doses; report promptly.
• Sleepiness: Some people experience unusual drowsiness or sudden sleep onset—avoid driving if affected.
• Impulse control problems: Uncontrollable urges (e.g., gambling, compulsive shopping, binge eating, hypersexuality) have been reported with dopaminergic therapy. Seek advice if you notice changes in behaviour.
• Neuroleptic malignant syndrome–like symptoms (rare): severe muscle stiffness, fever, confusion—seek urgent help.
• Severe diarrhoea or dehydration: particularly important if diarrhoea is persistent, heavy, or leads to weakness.
• Dark urine: Entacapone can cause urine to look dark. This is usually harmless but let your clinician know if you also feel unwell.
• Liver problems (rare): Watch for yellowing of skin/eyes, severe fatigue, or unusual dark urine—contact a clinician promptly.

When to seek urgent medical help

Get urgent care if you develop:

• Chest pain, severe shortness of breath, or fainting
• Severe allergic reactions (swelling of face/lips, difficulty breathing)
• High fever with severe stiffness or marked confusion
• Black/tarry stools or vomiting blood
• Severe persistent diarrhoea or signs of dehydration

Practical use tips

Improve day-to-day symptom control

• Keep a symptom diary for the first few weeks: note timing of doses and when “on/off” episodes occur. This can help refine scheduling.
• Stay consistent with meal patterns, particularly around high-protein foods.
• If you experience wearing off before the next dose, report it—dose timing may be adjusted.

Reduce side effects and safety risks

• Stand up slowly to reduce dizziness from low blood pressure.
• Be careful with activities that require alertness if you feel drowsy.
• If nausea occurs, taking doses as directed and maintaining small, consistent snacks may help (discuss options with your pharmacist).
• Check hydration, especially if you develop diarrhoea.

Driving and operating machinery

Because Stalevo can cause dizziness or sudden sleepiness in some people, avoid driving or operating machinery if you feel drowsy or your reaction time is affected.

Alternative treatment options

There are several other therapies for Parkinson’s disease, and the best option depends on your symptoms, lifestyle, and tolerability.

Common alternative medicine approaches

• Levodopa/carbidopa products (without entacapone)
• Entacapone as an add-on to levodopa/carbidopa (where appropriate)
• Other COMT inhibitors used in Parkinson’s care (availability and suitability depend on local guidelines and individual factors)
• Dopamine agonists
• MAO-B inhibitors
• Amantadine in selected cases
• Other medications used to manage non-motor symptoms

Non-medicine options

• Physiotherapy and exercise programs tailored to Parkinson’s
• Occupational therapy for daily activities
• Speech therapy for voice/swallowing issues
• In selected cases, advanced therapies (where available and appropriate)

Do not switch medicines without clinician guidance, especially when levodopa doses change. Abrupt changes can destabilise symptoms.

FAQ

1) Is Stalevo the same as levodopa?

Stalevo contains levodopa plus carbidopa and entacapone. This combination aims to improve effectiveness and reduce fluctuations compared with levodopa alone in many treatment plans.

2) When will Stalevo start working?

Many people notice symptom improvement after taking levodopa-based therapy, but the timing can vary. Stalevo is designed to provide more sustained benefit between doses; your clinician may adjust timing to reduce “off” periods.

3) Can I take Stalevo with food?

It’s often taken with or without food, but protein-rich meals can reduce absorption and affect symptom control in some people. Try to keep meals and protein intake patterns consistent, and discuss any dietary strategy with your healthcare professional.

4) What should I do if I miss a dose?

Generally, don’t double up. Take the missed dose only if it’s close enough to the next scheduled time to avoid a large gap, otherwise skip and continue your usual schedule. Confirm with your pharmacist if you’re unsure.

5) Does entacapone cause dark urine?

Yes. Entacapone can cause dark or brown urine. This is often harmless, but you should contact your clinician if you also have symptoms such as dizziness, fever, severe diarrhoea, or yellowing of the skin/eyes.

6) Can I drink alcohol while using Stalevo?

It’s generally recommended to limit or avoid alcohol due to potential increases in dizziness, sedation, and fall risk. If you choose to drink, do so cautiously and watch for worsening drowsiness or balance issues.

7) Are there medicines I must avoid?

Some medicines can interact with Stalevo, including certain antidepressants and MAO inhibitors, some antipsychotics, and other drugs that affect the nervous system or blood pressure. Always provide your full medication list to your pharmacist.

8) What side effects are most important to report?

Report hallucinations, confusion, fainting, severe or persistent diarrhoea, unusual sleepiness, and any new compulsive behaviours. Seek urgent help for severe symptoms such as high fever with stiffness or allergic reactions.

9) Can Stalevo cause dyskinesia?

Yes. Dyskinesia (involuntary movements) can occur, especially with higher levodopa exposure. Your clinician may adjust dose or timing to reduce this.

10) What if I need long-term treatment?

Parkinson’s disease is typically chronic, and levodopa-based therapy is often long-term. Ongoing monitoring helps balance symptom control with side effects such as blood pressure changes, sleepiness, hallucinations, and dyskinesia.

Summary

Stalevo is a combination Parkinson’s medicine containing carbidopa, levodopa, and entacapone. It helps increase dopamine activity and extends levodopa’s effect, supporting better mobility and reduced “off” periods. Its performance can be influenced by protein-rich meals and interactions with other medicines, alcohol, and individual health factors. By following a consistent dosing schedule, monitoring side effects, and discussing any concerns early, many people achieve meaningful improvement in day-to-day functioning.
