Stalevo (Carbidopa/Entacapone/Entacapone) — Medicine Information (Australia)

Stalevo is a combination medicine used in the treatment of Parkinson’s disease. It contains carbidopa and two active components related to entacapone (as provided in the product formulation). Together, these medicines help improve movement, reduce “off” periods, and support more reliable control of Parkinson’s symptoms.

This page provides patient-friendly information about how Stalevo works, how it is used, common timing considerations, food and medicine interactions, safety guidance, and practical tips for getting the most from treatment in Australia.

Quick Facts

• Brand name: Stalevo
• Active ingredients: Carbidopa + Entacapone (combination formulation)
• Used for: Parkinson’s disease to reduce “wearing off” and improve mobility
• How it works: Supports dopamine availability in the brain and reduces breakdown of levodopa
• Common form: Oral tablets
• Typical dosing approach: Based on individual response and current Parkinson’s medicines

What Stalevo Is Used For

Stalevo is indicated for people with Parkinson’s disease who take levodopa-based treatment and experience:

• Wearing off (motor symptoms returning before the next dose of levodopa)
• “Off” episodes between doses

Stalevo is generally used as part of a broader Parkinson’s treatment plan that may include other medicines such as levodopa. Your clinician may adjust overall therapy when starting or changing Stalevo.

How Stalevo Works (Mechanism of Action)

Parkinson’s disease is associated with reduced dopamine activity in the brain. Levodopa is a key medication that helps increase dopamine levels, but it can be broken down in the body before reaching the brain. Stalevo’s components target different steps to improve the effect of levodopa:

• Carbidopa: Helps prevent the breakdown of levodopa in the bloodstream and increases the amount that reaches the brain.
• Entacapone: Inhibits an enzyme called catechol-O-methyltransferase (COMT), which helps slow the breakdown of levodopa. This may prolong levodopa’s benefit and reduce fluctuations.

Result: Improved mobility and more consistent symptom control, especially for people who experience “wearing off.”

Pharmacokinetics (How the Body Handles Stalevo)

Pharmacokinetics describe absorption, distribution, metabolism, and excretion. While exact values can vary by person, the following points are helpful for understanding typical behaviour in the body.

• Absorption: Stalevo is taken by mouth and absorbed through the gastrointestinal tract.
• Onset of effect: Clinical benefit is usually expected after taking the dose, often aligning with levodopa onset used in Parkinson’s regimens.
• Distribution: Active components influence pathways related to dopamine availability in the body and brain.
• Metabolism: Entacapone affects COMT-mediated metabolism of levodopa; carbidopa supports more levodopa reaching systemic circulation and the brain.
• Elimination: Metabolites are primarily eliminated through the body’s natural routes (commonly involving the kidneys and bile pathways for related compounds).

Practical implication: Because Parkinson’s symptoms and dosing schedules can be sensitive to timing, Stalevo should usually be taken consistently relative to meals and other medicines, as advised by your clinician or pharmacist.

Typical Use and Dosing Timing

Stalevo is taken to improve control of Parkinson’s symptoms throughout the day. Doses are often scheduled to reduce “off” periods.

When to take Stalevo

• Consistency is key: Take Stalevo at the times your healthcare team has planned.
• With or without food: You may be advised to take it with meals or with a light snack depending on your overall levodopa regimen and tolerance. Some people find nausea or absorption varies with meals.
• Relation to other Parkinson’s doses: Stalevo timing should be coordinated with other levodopa-containing therapy if present.

Starting and adjusting dose

Dose selection and adjustments are typically individualized, based on:

• Your current Parkinson’s medication plan
• How often you experience “off” periods
• Tolerability (e.g., side effects such as diarrhoea, nausea, or low blood pressure)
• Other health conditions (including liver impairment)

Important: Do not change your dose schedule abruptly without advice. Changes may require careful monitoring of symptom control and side effects.

Indications (When Stalevo May Be Appropriate)

In general terms, Stalevo may be used for Parkinson’s disease in adults who:

• Take levodopa-based treatment
• Experience motor fluctuations, particularly wearing off or off periods
• Need improved duration and steadier relief

Availability of specific formulations and approved indications can vary. In Australia, final indication and suitability should be confirmed with your treating healthcare professional and the product information approved for your region.

Dosing (Patient-Friendly Guidance)

Because Stalevo is a combination tablet, your tablet strength will depend on your existing Parkinson’s medicines and dosing needs. The schedule is tailored to your symptoms.

General approach

• Take tablets whole with water (unless your clinician gives different instructions).
• Do not double up to make up for a missed dose.
• Follow your medication schedule as written on your label.

If you miss a dose

If you miss a dose:

• Take it when you remember unless it is close to the time of the next scheduled dose.
• Skip the missed dose if you are near your next dose.
• Contact your pharmacist or clinician if you are unsure.

Typical dosing frequency

Many Parkinson’s regimens involve multiple doses per day. Your schedule may change as symptoms fluctuate over time.

Note: This information is general. Your exact dosing and tablet strength must come from your medication plan.

Food Interactions and Meals

Food can influence how medicines are absorbed. For levodopa-related therapy, large or high-protein meals may reduce absorption in some people.

How meals may affect Stalevo

• Protein timing: Some people find that a high-protein meal (meat, dairy, eggs, protein shakes) can reduce the effect of levodopa-based treatment.
• Spacing meals: Clinicians sometimes recommend timing protein later in the day or distributing protein evenly if motor control becomes inconsistent.
• Nausea: If you feel nauseated, taking doses with a light snack may help (confirm with your pharmacist/clinician).

Practical tip: Keep meal patterns consistent where possible. If you change your diet significantly (e.g., increased protein intake), monitor symptom response and discuss with your healthcare team.

Alcohol and Medicine Interactions

Alcohol

Alcohol may worsen side effects such as:

• Dizziness and light-headedness
• Sleepiness
• Falls risk

Because Stalevo can affect blood pressure and alertness in some individuals, it is generally advisable to limit or avoid alcohol unless your clinician says it is safe for you.

Medicines that may interact with Stalevo

Interactions can occur with medicines that affect dopamine signalling, liver enzymes, blood pressure, and gastrointestinal function. Tell your pharmacist or clinician about all medicines and supplements you use, including over-the-counter products.

• Antidepressants and MAO inhibitors: Some antidepressants and MAO-related therapies can interact with Parkinson’s medicines. Your healthcare professional may adjust doses or choose alternatives.
• Antihypertensives: Medicines for high blood pressure may increase the chance of low blood pressure (especially when standing).
• Other Parkinson’s medicines: Combination therapy can increase risk of side effects such as dyskinesia or hallucinations if not balanced.
• Iron preparations: Iron can affect the absorption of some Parkinson’s medicines in certain regimens. Separate dosing may be needed depending on your plan.
• Metoclopramide: In some situations, metoclopramide may influence dopamine-related pathways.
• Diarrhoea-causing medicines: Because entacapone can contribute to diarrhoea, avoid or carefully monitor other agents that also cause diarrhoea.

Important: Do not start, stop, or change doses of any medicine without advice. If you develop new symptoms after a medicine change, contact your healthcare provider.

Safety Profile: Common and Important Side Effects

Like all medicines, Stalevo can cause side effects. Not everyone experiences them, and severity varies.

Common side effects

• Disc-shaped or dark urine: Entacapone can turn urine orange-brown. This is usually harmless.
• Nausea
• Diarrhoea (sometimes more likely in early treatment or with dose changes)
• Stomach discomfort
• Dizziness or light-headedness
• Dyskinesia (involuntary movements) — may occur if levodopa effect becomes too strong

Serious side effects — seek urgent medical help

Contact urgent care or seek medical help immediately if you experience:

• Severe allergic reaction (e.g., swelling of the face/lips, breathing difficulty, widespread rash)
• Chest pain, severe shortness of breath, fainting
• Confusion, severe agitation, fever, or muscle stiffness (particularly if symptoms are rapidly worsening)
• Persistent severe diarrhoea, signs of dehydration (e.g., very dry mouth, reduced urination)

Impulse control and behavioural changes

Some people taking dopaminergic medicines (including combinations used for Parkinson’s) may experience changes such as:

• Gambling urges
• Compulsive shopping
• Increased sexual drive
• Other unusual urges or behaviours

Tell your clinician promptly if you or your family notice these changes.

Sleepiness and sudden sleep

Some patients may experience sleepiness or rarely falling asleep suddenly. Use caution when driving or operating machinery and inform your healthcare professional if this occurs.

Practical Use Tips (Daily Success Strategies)

• Use a medication routine: Tie doses to daily routines (e.g., breakfast, midday, evening) consistent with your plan.
• Keep a symptom diary: Record “on/off” times, dyskinesia, and side effects. This helps clinicians fine-tune dosing.
• Manage diarrhoea early: If diarrhoea begins, maintain hydration and speak with your pharmacist/clinician promptly. Dose adjustment or supportive care may be needed.
• Stand up slowly: To reduce dizziness related to blood pressure changes, rise gradually from sitting/lying.
• Be prepared for orange-brown urine: This can be normal with entacapone. Still, if urine changes are accompanied by pain, fever, or yellowing of eyes/skin, seek advice.
• Plan around protein: If your “on” time becomes shorter around high-protein meals, discuss meal timing strategies with your healthcare team.
• Medication reviews: Bring your full medication list to appointments, including supplements and herbal products.

Missed Dose, Overdose, and When to Contact Help

If you suspect you have taken too much Stalevo or you have severe side effects, contact a healthcare professional or local poison information service for guidance. Australia has poison information services accessible by phone; your pharmacist can provide the correct number for your state.

When to contact your pharmacist/clinician urgently:

• Severe or persistent diarrhoea
• Fainting or severe dizziness
• Hallucinations or severe confusion
• Rapid deterioration in mobility or uncontrolled movements

Alternative Options

Alternatives depend on your symptoms, current levodopa regimen, and side effects. Your clinician may consider:

• Levodopa/carbidopa combinations without entacapone (if fluctuations are mild or entacapone causes troublesome side effects)
• Other COMT inhibitors (where clinically appropriate)
• Different levodopa formulations (e.g., extended-release options in some cases)
• Other Parkinson’s medicines such as dopamine agonists, MAO-B inhibitors, or adjunct therapies (chosen based on your overall profile)

Switching medicines should be supervised. Dosing schedules and tablet strengths may differ, and changes can affect symptom control.
