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

Stalevo® is a combination medicine used to treat symptoms of Parkinson’s disease. It brings together three active ingredients: levodopa, carbidopa, and entacapone. Together, these medicines help replace dopamine in the brain and reduce “off” periods (when symptoms return).

This guide is written for patients and carers. It explains how Stalevo works, how it is typically taken, key safety information, and what to consider with food, alcohol, and other medicines. Always follow the directions provided by your healthcare professional and read the product information leaflet supplied with your medicine.

Quick facts

Basic product information

How Stalevo works (mechanism of action)

Parkinson’s disease involves reduced dopamine activity in the brain. Levodopa is a precursor that the body can convert into dopamine, helping restore dopamine levels and improve symptoms such as stiffness, slowness, and tremor.

However, levodopa can be broken down before it reaches the brain. Stalevo includes two medicines that address this:

• Carbidopa: blocks enzymes in the body that would otherwise break down levodopa before it reaches the brain. This means more levodopa is available for brain conversion and can reduce certain side effects related to peripheral levodopa breakdown.
• Entacapone: inhibits an enzyme called COMT (catechol-O-methyltransferase). COMT normally helps break down levodopa. By inhibiting COMT, entacapone helps prolong levodopa’s effect and can reduce “wearing off” between doses.

The result is smoother symptom control for many people—particularly those who experience predictable end-of-dose deterioration.

Pharmacokinetics (how the body handles it)

“Pharmacokinetics” describes absorption, distribution, metabolism, and elimination of a medicine. While individual responses vary, the key practical points for Stalevo are:

• Levodopa: levels rise after oral dosing and then fall as levodopa is metabolised. Entacapone helps slow levodopa breakdown, often leading to a longer duration of benefit.
• Carbidopa: helps stabilise the peripheral conversion of levodopa so more reaches the brain; it also influences side effects related to peripheral metabolism.
• Entacapone: acts to reduce levodopa metabolism through COMT inhibition. Because entacapone is linked to the timing of levodopa doses, taking it consistently with each prescribed dose is important for best effect.

People with Parkinson’s disease can be sensitive to timing changes. If you miss a dose or alter your meal pattern significantly, symptom control may change.

What Stalevo is used for (indications)

Stalevo is generally used in adults with Parkinson’s disease to improve motor symptoms and to help reduce “off” periods. “Off” periods are times when medication effect wears off and symptoms return or worsen.

Your healthcare professional may consider Stalevo when symptoms suggest that the effect of levodopa is not lasting long enough, and when a combination therapy plan including entacapone is appropriate.

Typical dosing and timing

Dose strengths vary. Stalevo tablets are available in different combinations of levodopa/carbidopa/entacapone, and your exact dose should match your current treatment plan. Do not change your dose or tablet strength without medical advice.

General timing principles

• Take Stalevo at regular times as instructed to maintain steadier dopamine replacement.
• For most people, doses are taken several times daily. The number of doses depends on your symptoms and previous therapy.
• Keep consistency: sudden changes in dosing timing may trigger “on/off” fluctuations.
• If a dose is missed: follow the directions provided by your pharmacist or healthcare professional. If you’re unsure, contact a pharmacist for guidance rather than doubling up.

How to take it

• Swallow tablets whole with water.
• Follow your prescribed schedule closely.
• Do not stop suddenly unless advised—abrupt changes can worsen symptoms.

Practical example: If your regimen is designed to cover morning-to-evening symptom control, taking doses consistently around breakfast, midday, and evening (or as directed) can help reduce “wearing off.”

Food interactions and dietary considerations

Food can influence how quickly levodopa is absorbed. The most important practical point is that protein can interfere with levodopa absorption for some people. Protein competes with levodopa for transport across the gut and into the brain.

What to do

• If you notice your medication works well at some times and poorly at others, consider whether your meals are higher in protein.
• Ask your healthcare team whether a timing adjustment of protein (for example, moving the largest protein serving to later in the day) is appropriate for you.
• Keep a consistent diet pattern day-to-day where possible, so dosing timing and dietary protein are not constantly changing.

Tip for missed “wearing off” patterns

If symptoms become more unpredictable, track whether changes in meal timing, portion sizes, or high-protein foods coincide with medication effect. This can help your clinician adjust your plan.

Alcohol and medicine interactions

Alcohol

• Alcohol may worsen dizziness, drowsiness, and low blood pressure, which can occur with Parkinson’s medicines.
• Alcohol can also affect judgement and increase fall risk.

For safety, it’s generally advisable to limit alcohol and discuss your intake with your healthcare professional.

Medicine interactions (important)

Stalevo can interact with several classes of medicines. The most important examples include:

• Antidepressants (MAO inhibitors): Some antidepressants can affect dopamine metabolism and increase risk of side effects. Older MAO-inhibitor combinations are especially important to review with your clinician.
• Non-selective MAO inhibitors and certain combinations: may require special caution or may not be suitable.
• Antipsychotics and anti-nausea medicines that block dopamine receptors: may reduce effectiveness or worsen Parkinson’s symptoms. Examples include some typical antipsychotics.
• Iron and some supplements: iron may affect levodopa absorption in some situations; spacing supplements away from doses may be advised.
• Other Parkinson’s medicines: combining therapies can increase the risk of side effects such as dyskinesia or hallucinations, depending on the regimen.
• Medicines causing sedation: combined use with Stalevo may increase drowsiness, confusion, and falls.

Always tell your pharmacist about:

• All medicines you currently take (including “as needed” medicines)
• Herbal products and supplements
• Any over-the-counter cold/flu products

Safety profile: side effects and when to seek help

Like all medicines, Stalevo can cause side effects. Not everyone will experience them, and many can be managed by dose adjustment or supportive care. If you’re concerned about a side effect, contact your healthcare professional promptly.

Common or notable side effects

• Dyskinesia (involuntary movements)
• Nausea or stomach upset
• Dizziness (including light-headedness)
• Dry mouth or appetite changes
• Low blood pressure (especially on standing)
• Diarrhoea (entacapone-containing regimens may be associated with diarrhoea)
• Darkened urine (can occur with entacapone; usually harmless—confirm with your pharmacist if unsure)

Serious or urgent symptoms (seek medical help)

Seek urgent medical attention or contact emergency services if you develop:

• Severe allergic symptoms (swelling of face/lips, trouble breathing)
• Severe confusion, agitation, or hallucinations that rapidly worsen
• Fainting or severe dizziness related to low blood pressure
• Severe, persistent diarrhoea or signs of dehydration
• Symptoms suggestive of a neuroleptic malignant syndrome–like reaction (high fever, severe muscle stiffness, confusion), especially if abrupt medication changes occur

Special risks to be aware of

• Sleepiness and sudden sleep episodes: Some people experience drowsiness. Avoid driving and dangerous activities if you feel unusually sleepy.
• Impulse-control disorders: Rarely, some people develop compulsive behaviours (such as gambling urges or increased libido). If you notice these changes, contact your healthcare professional.
• Psychiatric effects: Hallucinations or mood changes may occur, especially with dose increases or in vulnerable individuals.

Practical use tips (getting the best results)

• Use a medication schedule: Consider a diary or blister pack to keep doses consistent.
• Don’t “chase symptoms” too aggressively: If symptoms break through, contact your clinician/pharmacist rather than taking extra doses unless explicitly instructed.
• Track your pattern: Note when you go “on” and “off” each day. This can help refine timing.
• Manage nausea: Taking with water and following dietary advice may help. Your pharmacist can advise on supportive strategies.
• Stay hydrated, especially if you experience diarrhoea.
• Be careful with falls: Dizziness and low blood pressure can increase fall risk. Rise slowly from sitting/lying positions.

Missed dose guidance

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

• Do not double up to “catch up” unless your pharmacist or healthcare professional tells you to.
• Contact your pharmacist for personalised instructions if you’re uncertain.

Alternative options (other ways to manage Parkinson’s symptoms)

Treatment for Parkinson’s disease is individual. Alternatives to Stalevo may include:

• Levodopa + carbidopa (without entacapone)
• Levodopa formulations with other COMT inhibitors (depending on availability and clinical suitability)
• Dopamine agonists (for selected patients)
• MAO-B inhibitors (to support dopamine levels)
• Amantadine (in some cases for symptoms such as dyskinesia)
• Adjunctive therapies such as physiotherapy, speech therapy, and specialised Parkinson’s care

Your clinician can help determine which option—or combination—is best based on your symptom pattern, side effects, age, and other medical conditions.
