About Stalevo
Stalevo is a prescription-only medication approved in Australia for the treatment of Parkinson’s disease. It combines carbidopa, a peripheral DOPA-dec arboxylase inhibitor, with entacapone, a catechol-O-methyltransferase (COMT) inhibitor, and is taken together with levodopa to enhance and prolong dopamine availability in the brain. The tablet formulation (25/100/200 mg) is designed for adult patients who require more stable motor control than levodopa alone can provide, and it may also be used when patients experience “wearing-off” fluctuations during long-term therapy.
What is Generic Stalevo (Carbidopa, Entacapone)?
Generic Stalevo (Carbidopa, Entacapone) is a fixed-dose combination that belongs to the class of dopaminergic agents used in Parkinson’s disease management. In Australia the Therapeutic Goods Administration (TGA) approved the product as a prescription medicine, reflecting its safety and efficacy profile demonstrated in clinical trials. While the brand name Stalevo is manufactured by Novartis, the generic version is produced by multiple licensed manufacturers and offers the same active ingredients in identical strengths. Bioequivalence studies confirm that the generic delivers comparable plasma concentrations of carbidopa and entacapone, providing a cost-saving alternative without compromising therapeutic outcomes. The combination is intended to be used alongside levodopa, which is supplied in the same tablet in a fixed ratio.
How Stalevo Works
The therapeutic effect of Stalevo hinges on two complementary mechanisms:
- Carbidopa blocks the enzyme aromatic L-amino-acid decarboxylase (AADC) in peripheral tissues. By preventing the conversion of levodopa to dopamine outside the central nervous system, carbidopa reduces peripheral side effects (nausea, vomiting) and ensures that a larger proportion of the administered levodopa reaches the brain.
- Entacapone inhibits catechol-O-methyltransferase (COMT), an enzyme that metabolises levodopa to 3-O-methyldopa in the periphery and the brain. This inhibition extends levodopa’s half-life, smooths plasma concentration peaks, and mitigates the “wearing-off” phenomenon that often emerges after years of levodopa monotherapy.
When the tablet is swallowed, the levodopa component is absorbed in the small intestine, enters the bloodstream, and, protected by carbidopa, crosses the blood-brain barrier via the large neutral amino-acid transport system. Inside the brain, levodopa is converted to dopamine by AADC, replenishing deficient dopaminergic neurotransmission characteristic of Parkinson’s disease. Entacapone’s COMT blockade results in a more sustained levodopa level, translating into steadier motor function. Clinical pharmacokinetic data show an onset of symptom relief within 30-60 minutes, with a therapeutic window lasting approximately 4-6 hours, allowing patients to space doses three to four times daily.
Why Stalevo is Used for Neurological Conditions
- Mitigates “wearing-off” fluctuations - By prolonging levodopa exposure, the COMT inhibition reduces the periods of diminished motor control that occur before the next dose.
- Reduces required levodopa dose - The synergistic action allows clinicians to lower the overall levodopa load, potentially decreasing dyskinesia risk.
- Improves daily “ON” time - Studies such as the STRIDE-PD trial demonstrated a significant increase in the number of hours patients spent with adequate motor control compared with levodopa + carbidopa alone.
- First-line adjunct in guidelines - The Australian Parkinson’s Disease Management Guidelines recommend a COMT inhibitor like Stalevo for patients experiencing motor fluctuations despite optimal levodopa dosing.
- Convenient fixed-dose - The 25 mg carbidopa / 200 mg entacapone combination with 100 mg levodopa simplifies titration compared with separate tablets of each component.
- Comparable efficacy to separate agents - Head-to-head trials found that the fixed-dose tablet has similar efficacy and safety to taking levodopa/carbidopa plus entacapone (Comtan) as separate pills, while enhancing adherence.
Is Stalevo Right for You?
Stalevo is most appropriate for adults with Parkinson’s disease who are already receiving levodopa/carbidopa and begin to experience motor fluctuations or reduced “ON” time. Ideal candidates include patients who:
- Have stable renal function; dose adjustments may be required in severe renal impairment.
- Are not pregnant or nursing, as safety data in these populations are insufficient.
- Have no known hypersensitivity to carbidopa, entacapone, or any excipients in the tablet.
Elderly patients often tolerate the combination well but should start at the lowest dose and titrate slowly to monitor for orthostatic hypotension or hallucinations. Individuals with severe hepatic disease may require a reduced dosing frequency because entacapone is metabolised hepatically. If you have a history of neuropsychiatric symptoms, your clinician will weigh the benefits against the risk of exacerbating such effects.
Taking Stalevo Effectively
- Timing: Take Stalevo with or without food; a light meal may lessen nausea, but high-protein meals can interfere with levodopa absorption, so spacing protein-rich foods at least an hour before or after dosing is advisable.
- Dose escalation: Begin with one tablet per dose and increase gradually (often in .5-tablet increments) until motor symptoms are optimally controlled, not exceeding four tablets per day unless directed by a physician.
- Missed dose: If a dose is missed and the next scheduled dose is more than 4 hours away, take the missed tablet promptly. If the next dose is imminent, skip the missed one to avoid overdosing.
- Travel tips: Carry a sufficient supply in your original container, and keep the medication at room temperature away from moisture. For long flights, consider a portable pill organizer to maintain your schedule across time zones.
- Hydration: Adequate fluid intake helps prevent constipation, a common issue with dopaminergic therapy.
Understanding Side Effects and How to Manage Them
Most adverse events stem from dopamine-related activity or the metabolic actions of carbidopa and entacapone:
- Nausea and vomiting - Result from peripheral dopamine excess; taking Stalevo with a small snack or using anti-emetics like domperidone (prescribed) can alleviate symptoms.
- Orthostatic hypotension - Caused by vasodilatory dopamine effects; rise slowly from sitting, stay hydrated, and avoid sudden postural changes.
- Hallucinations or confusion - More frequent in older adults or those with pre-existing cognitive decline; dose reduction or switching to a lower-dose regimen may be necessary.
- Diarrehia - Entacapone can increase gastrointestinal motility; a low-fat, high-fiber diet and probiotics may help.
- Urine discoloration - A harmless brownish tint may appear due to entacapone metabolites; reassure patients that this is not a sign of toxicity.
Serious side effects such as severe liver enzyme elevation, allergic rash, or sudden onset of mood swings require immediate medical attention. Regular liver function tests are recommended during the first few months of therapy.

Frequently Asked Questions
-
Can Stalevo be taken on an empty stomach? Yes, it can be taken with or without food, but a light snack may reduce nausea. High-protein meals should be avoided around dosing times because they compete with levodopa for absorption.
-
What distinguishes Stalevo from taking levodopa, carbidopa, and entacapone separately? The fixed-dose tablet simplifies regimen complexity, improves adherence, and ensures a precise carbidopa-to-entacapone ratio, which can be difficult to achieve with separate pills.
-
How quickly will I notice an improvement after starting Stalevo? Most patients experience reduced “wearing-off” episodes within one to two weeks of stable dosing, though optimal benefit may require gradual titration over several weeks.
-
Is Stalevo suitable for patients over 80 years old? It can be used in the elderly, but clinicians usually start at the lowest possible dose and monitor for orthostatic hypotension, hallucinations, and bladder dysfunction.
-
Will Stalevo interact with my antihypertensive medication? Because entacapone can cause mild hypotension, patients on blood-pressure-lowering drugs should have their blood pressure checked after initiating therapy and adjust doses if necessary.
-
Can I switch from brand-name Stalevo to the generic without a doctor’s visit? Switching requires a prescription, so you must consult your prescriber. Once approved, the generic substitution is safe due to proven bioequivalence.
-
What should I do if I miss a dose for more than 12 hours? Contact your healthcare provider. They may advise a temporary dose increase or a schedule adjustment to regain symptom control.
-
Are there any dietary supplements that should be avoided? High-dose vitamin B6 can diminish carbidopa’s effect on levodopa metabolism. Discuss any supplement use with your clinician to avoid unintended interactions.
-
Does Stalevo affect sleep patterns? Some patients report insomnia or vivid dreams, likely related to increased central dopamine. Consuming the dose earlier in the day and avoiding caffeine in the evening can mitigate this.
-
Is Stalevo covered by the Pharmaceutical Benefits Scheme (PBS)? In Australia, Stalevo may be listed on the PBS for eligible patients with advanced Parkinson’s disease; eligibility criteria and co-payment amounts vary by individual circumstance.
