Prolopa is a prescription medication used to manage the symptoms of Parkinson’s disease, including tremors, muscle stiffness, and slowness of movement.
It contains two active ingredients: levodopa and benserazide. Levodopa is converted into dopamine in the brain, helping improve movement and coordination. Benserazide prevents levodopa from being broken down too early outside the brain, allowing more of the medication to reach its intended destination.
Although Prolopa can improve movement and help patients perform daily activities, it may cause side effects that require careful medical monitoring.
Some patients may experience dizziness, low blood pressure, involuntary movements, hallucinations, or changes in mood and behavior. Certain medical conditions and medications may also increase the risk of serious complications.
Prolopa should only be taken under medical supervision. Inform your healthcare provider about all existing medical conditions, medications, and supplements before starting treatment.
Glaucoma and Increased Eye Pressure
Patients with a history of glaucoma should inform their healthcare provider before taking Prolopa.
Glaucoma is an eye condition that can damage the optic nerve, which transmits visual information from the eye to the brain. Elevated pressure inside the eye is an important risk factor for this damage.
Levodopa may affect pressure inside the eye, making treatment unsuitable for certain patients.
Prolopa is contraindicated in patients with narrow-angle glaucoma, meaning they should not use the medication.
Patients with well-controlled open-angle glaucoma may be considered for treatment under specialist supervision, with regular monitoring of eye pressure.
Your healthcare provider may recommend eye examinations before and during treatment.
Report any new visual disturbances, eye pain, or unusual changes in vision.
Do not take Prolopa if you have narrow-angle glaucoma. Patients with open-angle glaucoma should discuss treatment with their healthcare provider and may require regular eye pressure monitoring.
Medication Interactions With Prolopa
Prolopa may interact with certain medications, including antidepressants, antipsychotics, blood pressure medications, and other drugs that affect dopamine activity.
These interactions may reduce the effectiveness of Prolopa or increase the likelihood of adverse effects.
Certain antipsychotic medications block dopamine receptors in the brain. Because Prolopa works by increasing dopamine availability, these medications may interfere with its ability to control Parkinson’s symptoms.
Some antidepressants may also interact with Prolopa.
In particular, nonselective monoamine oxidase inhibitors (MAOIs) must not be taken with Prolopa because the combination can cause dangerous increases in blood pressure and other serious reactions.
A waiting period is generally required when switching from an MAOI to Prolopa.
Other medications may increase dizziness, confusion, hallucinations, or low blood pressure when taken with levodopa.
Your healthcare provider will review your medication list and determine whether dosage adjustments or alternative treatments are necessary.
Tell your healthcare provider about all prescription medications, over-the-counter products, vitamins, and supplements you take. Do not combine Prolopa with contraindicated MAOIs or change psychiatric medications without medical advice.
Heart Disease and Cardiovascular Problems
Patients with a history of heart disease should inform their healthcare provider before taking Prolopa.
Levodopa can affect blood pressure and heart rhythm, which may be concerning for patients with certain cardiovascular conditions.
These conditions include angina, previous heart attacks, and irregular heartbeats.
Angina occurs when the heart muscle does not receive enough oxygen-rich blood, causing chest pain or discomfort.
Some patients receiving levodopa may experience palpitations, changes in heart rhythm, or fluctuations in blood pressure.
Patients with a history of heart attack or certain cardiac arrhythmias may require closer monitoring when treatment begins.
Prolopa is contraindicated in patients with uncompensated cardiovascular disease, meaning serious heart disease that is not adequately controlled.
Patients with stable heart conditions may require individualized assessment and monitoring.
Your healthcare provider may recommend blood pressure measurements, electrocardiograms, or other cardiovascular evaluations.
Tell your healthcare provider if you have heart disease, angina, irregular heartbeats, or a history of heart attack. Seek urgent medical attention for chest pain, fainting, or a new serious heart rhythm disturbance.
Dizziness, Drowsiness, and Alcohol Consumption
Prolopa may cause dizziness, lightheadedness, or drowsiness, particularly when treatment begins or the dosage increases.
These effects can interfere with concentration, coordination, and the ability to perform activities safely.
Some patients may also experience sudden episodes of falling asleep without warning.
This can be particularly dangerous while driving, operating machinery, or performing tasks that require continuous attention.
Alcohol may worsen dizziness, sleepiness, and impaired coordination.
Other medications that cause drowsiness, such as sleeping pills and certain anxiety medications, may also increase these effects.
Until you know how Prolopa affects you, avoid activities that could become dangerous if you suddenly feel sleepy or lose your balance.
If you experience excessive daytime sleepiness or sudden sleep episodes, contact your healthcare provider.
Avoid alcohol if it worsens dizziness or drowsiness, and do not drive or operate machinery if you experience excessive sleepiness or sudden episodes of falling asleep.
Involuntary Movements (Dyskinesias)
Prolopa may cause involuntary movements, known as dyskinesias, particularly during long-term treatment or when higher doses are required.
Dyskinesias are uncontrolled movements that may affect the face, arms, legs, neck, or other parts of the body.
These movements may appear as twisting, writhing, jerking, or repetitive motions.
They can develop when dopamine activity fluctuates during levodopa treatment.
Some patients experience mild movements that do not significantly interfere with daily activities, while others develop more pronounced symptoms.
Dyskinesias may become more noticeable as Parkinson’s disease progresses and the response to levodopa changes.
If involuntary movements develop, your healthcare provider may adjust the dosage, change the timing of administration, or recommend additional treatment.
Do not reduce or stop Prolopa independently because sudden changes may worsen Parkinson’s symptoms.
Contact your healthcare provider if you develop new or worsening involuntary movements. Dosage adjustments may help reduce dyskinesias while maintaining control of Parkinson’s symptoms.
Low Blood Pressure When Standing (Orthostatic Hypotension)
Prolopa may cause a sudden decrease in blood pressure when a patient stands up from a sitting or lying position.
This condition is called orthostatic hypotension.
It occurs when the body cannot adjust blood pressure quickly enough during a change in position.
Symptoms may include dizziness, lightheadedness, blurred vision, weakness, or fainting.
Some patients may also experience difficulty maintaining balance, increasing the risk of falls and injuries.
The risk may be greater when treatment begins, the dosage increases, or Prolopa is combined with blood pressure medications.
To reduce symptoms, stand up slowly after sitting or lying down. If you feel dizzy, sit or lie down until the sensation improves.
Your healthcare provider may recommend checking your blood pressure regularly and reviewing medications that contribute to low blood pressure.
Prolopa may cause orthostatic hypotension. Change positions slowly and contact your healthcare provider if you experience frequent dizziness, fainting, or falls.
Liver Disease and Liver Function
Patients with liver disease should inform their healthcare provider before starting Prolopa.
The liver helps process many medications and contributes to several important metabolic functions.
Patients with significant liver impairment may have an increased risk of medication-related complications.
Under the Canadian prescribing information, Prolopa is contraindicated in patients with uncompensated liver disease, meaning liver function is seriously impaired or inadequately controlled.
Patients with a history of liver problems may require additional assessment before treatment begins.
During prolonged treatment, your healthcare provider may recommend periodic liver function tests, particularly if you have other medical conditions or take medications that affect the liver.
Report symptoms such as persistent nausea, unexplained fatigue, dark urine, or yellowing of the skin or eyes.
These symptoms may indicate a liver-related problem that requires medical evaluation.
Tell your healthcare provider if you have liver disease. Patients with uncompensated liver impairment should not use Prolopa, and those with other liver conditions may require additional monitoring.
Depression, Anxiety, and Other Psychiatric Symptoms
Prolopa may cause or worsen certain psychiatric symptoms, particularly in patients with a history of mental health conditions.
Dopamine plays an important role not only in movement but also in mood, motivation, and behavior.
Because Prolopa increases dopamine availability, some patients may experience changes in thinking, emotions, or behavior during treatment.
Possible symptoms include anxiety, agitation, confusion, hallucinations, and unusual changes in mood.
Hallucinations involve seeing, hearing, or sensing things that are not actually present.
Some patients may also develop paranoid thoughts or other symptoms of psychosis.
Depression can occur in patients with Parkinson’s disease and may be related to the underlying condition, medication effects, or other factors.
Patients with severe psychiatric disorders may not be suitable candidates for Prolopa treatment, particularly when symptoms are uncontrolled.
Your healthcare provider may monitor for changes in mood and behavior throughout treatment.
Family members and caregivers should also report unusual behavioral changes that the patient may not recognize.
Contact your healthcare provider promptly if you experience worsening anxiety, depression, confusion, hallucinations, or unusual behavioral changes. Seek emergency assistance if you develop suicidal thoughts with an immediate risk of self-harm.
Impulse Control Disorders and Behavioral Changes
Prolopa may also be associated with changes in impulse control.
Impulse control disorders occur when a person experiences strong urges to perform certain activities and has difficulty controlling those behaviors.
Examples include compulsive gambling, excessive shopping, binge eating, and increased sexual urges.
These behaviors may develop during treatment with medications that affect dopamine activity.
Some patients may not recognize that their behavior has changed.
Family members or caregivers may notice unusual spending, increased risk-taking, or repetitive activities that interfere with daily life.
These changes can affect relationships, finances, and overall well-being.
Your healthcare provider may recommend adjusting the medication if significant impulse control problems develop.
Do not stop Prolopa suddenly without medical supervision.
Tell your healthcare provider if you or someone close to you notices new or uncontrollable urges involving gambling, shopping, eating, or other behaviors. These symptoms may be related to dopaminergic treatment.
Melanoma and Suspicious Skin Lesions
Patients with Parkinson’s disease may have an increased risk of developing melanoma, a serious form of skin cancer.
Melanoma develops when pigment-producing cells in the skin, called melanocytes, begin growing abnormally.
Research has identified an association between Parkinson’s disease and melanoma, although it remains unclear whether this relationship is caused by the disease itself, its treatment, or other factors.
Patients taking Prolopa should inform their healthcare provider if they have a history of melanoma, other skin cancers, or suspicious skin lesions.
Regular skin examinations may be recommended during treatment.
Patients should also monitor their skin for changes in existing moles or the appearance of new, unusual lesions.
Warning signs may include changes in a mole’s size, shape, color, or border, or a lesion that bleeds or fails to heal.
Your healthcare provider may recommend assessment by a dermatologist if suspicious changes are identified.
Patients taking Prolopa should have periodic skin examinations. Report new or changing moles, unusual skin growths, or other suspicious skin lesions promptly.
High-Protein Foods and Reduced Medication Effectiveness
Certain foods, particularly those high in protein, may interfere with the effectiveness of Prolopa.
Levodopa must be absorbed through the digestive system and transported into the brain before it can be converted into dopamine.
Protein-rich foods are broken down into amino acids, some of which compete with levodopa for transport.
As a result, taking Prolopa close to a high-protein meal may reduce or delay its effects in some patients.
Foods that may influence levodopa response include meat, poultry, fish, eggs, dairy products, beans, and protein supplements.
Patients may notice increased stiffness, tremors, or slowness of movement after certain meals.
However, not everyone taking Prolopa experiences significant food-related interactions.
Protein remains an essential part of a healthy diet, particularly for maintaining muscle strength and preventing malnutrition.
Patients should not eliminate or severely restrict dietary protein without medical advice.
If meals interfere with symptom control, your healthcare provider or dietitian may recommend changing the timing of Prolopa doses or redistributing protein intake throughout the day.
High-protein meals may reduce Prolopa’s effectiveness in some patients. Consult your healthcare provider before changing your medication schedule or restricting dietary protein.
Importance of Regular Medical Monitoring
Patients taking Prolopa should attend regular medical appointments to assess symptom control and identify potential complications.
Your healthcare provider will monitor your response to treatment and determine whether dosage adjustments are necessary.
Monitoring may include blood pressure measurements, assessments of movement and balance, and evaluation of involuntary movements.
Patients with existing medical conditions may also require blood tests or additional examinations.
Your healthcare provider may periodically review liver function, kidney function, blood counts, and cardiovascular health when appropriate.
Changes in mood, sleep patterns, memory, or behavior should also be discussed during follow-up appointments.
As Parkinson’s disease progresses, some patients may develop wearing-off effects or sudden changes between periods of good and poor mobility.
These changes may require adjustments to the treatment schedule.
Do not increase the number of capsules or change the timing of medication without consulting your healthcare provider.
Regular medical follow-up is important for maintaining symptom control, identifying side effects, and safely adjusting Prolopa treatment as Parkinson’s disease progresses.
Important Safety Reminders When Taking Prolopa
Prolopa helps manage Parkinson’s disease symptoms by increasing dopamine availability in the brain.
However, treatment may cause dizziness, low blood pressure, involuntary movements, drowsiness, hallucinations, and changes in mood or behavior.
Patients with narrow-angle glaucoma, uncompensated heart or liver disease, or certain severe psychiatric conditions should not use Prolopa.
Patients with a history of melanoma, stable cardiovascular disease, or other significant medical conditions may require additional assessment and monitoring.
High-protein meals and certain medications may also interfere with treatment effectiveness.
Abruptly stopping Prolopa can cause severe worsening of Parkinson’s symptoms and, rarely, a life-threatening reaction involving high fever, muscle rigidity, and confusion.
Never stop Prolopa suddenly or change your dosage without medical supervision. Seek emergency medical attention if you experience severe muscle rigidity with fever, sudden loss of consciousness, chest pain, or other serious symptoms.
