# Carbidopa 25 mg + Levodopa 100 mg ## SHORT DESCRIPTION Carbidopa 25 mg + Levodopa 100 mg is a **combination medicine used to manage symptoms of Parkinson's disease and parkinsonism**. Levodopa is converted into dopamine in the brain, while carbidopa helps more levodopa reach the brain by reducing its breakdown outside the brain. This combination can help improve **slowness of movement, muscle stiffness and tremor** associated with Parkinson's disease. ## KEY BENEFITS * Helps improve **slowness of movement (bradykinesia)** * Helps reduce muscle stiffness and rigidity * May improve Parkinson's disease-related tremor * Helps improve mobility and daily functioning * Carbidopa allows more levodopa to reach the brain * Can reduce some unwanted peripheral effects of levodopa ## USES / INDICATIONS Carbidopa 25 mg + Levodopa 100 mg may be prescribed for: * **Parkinson's disease** * Parkinsonism associated with certain conditions * Bradykinesia or reduced movement * Muscle rigidity associated with Parkinson's disease * Tremor and other motor symptoms associated with dopamine deficiency The medicine does not cure Parkinson's disease, but it can significantly improve symptoms in many patients. ## HOW IT WORKS ### Levodopa Levodopa is a precursor of **dopamine**. It crosses the blood-brain barrier and is converted into dopamine in the brain. In Parkinson's disease, dopamine-producing neurons are reduced. Increasing dopamine availability helps improve movement and motor control. ### Carbidopa Carbidopa inhibits **dopa decarboxylase outside the brain**. This prevents a large proportion of levodopa from being converted into dopamine before reaching the brain. As a result: * More levodopa reaches the brain * Lower doses of levodopa may be effective * Peripheral nausea and other effects caused by dopamine formation may be reduced ## DOSAGE & ADMINISTRATION * Take Carbidopa 25 mg + Levodopa 100 mg exactly as prescribed. * The dose is individualized according to symptom severity, response and tolerability. * Treatment is often started at a lower dose and gradually adjusted by the doctor. * Take doses at consistent times each day. * Swallow tablets with water unless your specific formulation has different instructions. * Avoid suddenly stopping treatment unless instructed by your doctor. * Large amounts of high-protein food may interfere with levodopa absorption in some patients. Follow your healthcare professional's dietary advice. ### Missed Dose Take the missed dose when remembered unless it is nearly time for the next scheduled dose. Do not take two doses together. ## SIDE EFFECTS Common side effects may include: * Nausea * Vomiting * Loss of appetite * Dizziness * Headache * Dry mouth * Constipation * Sleepiness * Fatigue * Changes in blood pressure * Abnormal or involuntary movements With longer-term treatment, some patients may develop **motor fluctuations**, including wearing-off or dyskinesia. ### Serious Side Effects Seek medical attention if you experience: * Severe involuntary movements * Hallucinations or severe confusion * Fainting * Severe dizziness * Significant behavioral changes * Unusual urges or compulsive behaviors * Severe allergic reaction * Chest pain or significant heartbeat abnormalities * Severe daytime sleepiness or sudden sleep episodes ## PRECAUTIONS & WARNINGS * Do not stop carbidopa/levodopa suddenly without medical advice. Abrupt withdrawal can cause serious symptoms resembling **neuroleptic malignant syndrome**. * The medicine may cause dizziness or a sudden drop in blood pressure when standing. * Avoid driving or operating machinery if you experience excessive sleepiness, dizziness or sudden sleep episodes. * Tell your doctor if you have glaucoma, particularly narrow-angle glaucoma. * Tell your doctor if you have heart disease or a history of abnormal heart rhythms. * Inform your doctor if you have a history of psychiatric illness or hallucinations. * Carbidopa/levodopa can cause involuntary movements, particularly after prolonged treatment or dose adjustments. * Some patients may experience impulse-control disorders such as compulsive gambling, shopping, eating or sexual behavior. * Tell your doctor if you have a history of melanoma or unexplained skin lesions. * Monitor for worsening hallucinations, confusion or unusual behavior. * Rise slowly from sitting or lying positions to reduce dizziness. * Tell your doctor if you are pregnant, planning pregnancy or breastfeeding. ## DRUG INTERACTIONS Carbidopa/Levodopa may interact with: * **Non-selective MAO inhibitors** — should generally not be used with carbidopa/levodopa because of the risk of dangerous blood-pressure effects. * **Certain antipsychotic medicines** — may reduce the effectiveness of levodopa or worsen Parkinsonian symptoms. * **Iron supplements** — may reduce absorption of levodopa in some patients. Your doctor or pharmacist may recommend separating doses. * **Certain blood-pressure medicines** — may increase the risk of orthostatic hypotension. * **Metoclopramide and other dopamine-blocking medicines** — may reduce levodopa's effectiveness. * **High-protein meals** — dietary amino acids can compete with levodopa for absorption and transport in some patients. * Other medicines affecting dopamine or the nervous system may alter its effects. Always inform your doctor or pharmacist about all prescription medicines, over-the-counter medicines, vitamins and herbal supplements you take. ## STORAGE INFORMATION * Store according to the manufacturer's instructions. * Keep tablets in their original packaging. * Store at the recommended room temperature. * Protect from excessive heat, moisture and direct sunlight. * Keep the container tightly closed where applicable. * Keep out of reach of children. * Do not use after the expiry date. * Do not use tablets if the packaging is damaged or the medicine has changed in appearance. ## PRESCRIPTION STATUS **Prescription medicine.** Carbidopa 25 mg + Levodopa 100 mg should be used under the supervision of a qualified healthcare professional.

It is primarily used to manage **symptoms of Parkinson's disease and certain forms of parkinsonism**, including slowness of movement, rigidity and tremor. ### Is Carbidopa/Levodopa a cure for Parkinson's disease? No. It does not cure Parkinson's disease or restore damaged dopamine-producing nerve cells. It helps **control symptoms by increasing dopamine availability in the brain**. ### How does Levodopa work? Levodopa crosses the blood-brain barrier and is converted into **dopamine**, helping compensate for the reduced dopamine activity associated with Parkinson's disease. ### Why is Carbidopa combined with Levodopa? Carbidopa prevents levodopa from being converted into dopamine outside the brain. This allows **more levodopa to reach the brain** and can reduce some peripheral side effects. ### Does Carbidopa/Levodopa help tremors? Yes. It can improve several motor symptoms of Parkinson's disease, including **tremor, rigidity and slowness of movement**, although individual responses vary. ### How long does Carbidopa/Levodopa take to work?
