Frequently asked questions

What is Levodopa/Carbidopa/Entacapone used for?+
Levodopa/Carbidopa/Entacapone is a combination medication prescribed to manage the motor symptoms of Parkinson's disease, including tremor, rigidity, and bradykinesia, and to reduce OFF periods in patients with advanced disease.
How does Levodopa/Carbidopa/Entacapone work?+
Levodopa is converted to dopamine in the brain, restoring deficient neurotransmission. Carbidopa blocks peripheral conversion of levodopa, increasing its central availability, while entacapone inhibits the COMT enzyme, prolonging levodopa’s plasma half‑life and enhancing its effectiveness.
What is the usual dose of Levodopa/Carbidopa/Entacapone?+
The specific dose and dosing schedule are individualized by the prescribing clinician based on disease severity, patient response, and tolerability. Patients should follow the prescriber’s instructions and not adjust the dose on their own.

Safety data in pregnancy and lactation are limited, and the product is classified as having an unknown pregnancy category. It should only be used if the potential benefit justifies the potential risk, and a healthcare professional should be consulted.

How does Levodopa/Carbidopa/Entacapone compare with other Parkinson’s therapies?+

What are the most serious risks associated with Levodopa/Carbidopa/Entacapone?+
Serious risks include dyskinesia, hallucinations, severe hypotension, neuroleptic malignant syndrome, and rare allergic reactions such as anaphylaxis. Patients should be monitored closely for these events, especially during dose adjustments.
Who should not use Levodopa/Carbidopa/Entacapone?+
Patients with known hypersensitivity to levodopa, carbidopa, entacapone, or any excipients should avoid the product. It is also contraindicated in individuals taking non‑selective MAO inhibitors or those with severe cardiovascular instability without medical supervision.
