Before Using This Medicine
It is essential to inform your doctor about the following:
Any allergies you have, including allergies to this medication, its components, or other substances, such as foods or drugs. Be sure to describe the symptoms you experienced.

Precautions & Cautions
To ensure your safety, avoid driving and other activities that require alertness until you understand how this medication affects you. If you experience dizziness or lightheadedness, rise slowly from a sitting or lying position to minimize the risk of falling. Be cautious when navigating stairs.
Follow your doctor's instructions for monitoring your blood pressure. Do not discontinue this medication without consulting your doctor, as stopping it abruptly may lead to withdrawal symptoms. If you need to stop taking this medication, follow your doctor's guidance on how to taper off safely. Immediately contact your doctor if you experience any of the following symptoms when reducing the dose or stopping the medication: fever, confusion, severe muscle stiffness, apathy, anxiety, depression, fatigue, sleep disturbances, sweating, or pain.

Overdose Information
Overdose Symptoms:
- Nausea
- Vomiting
- Hyperkinesia (excessive movement)
- Hallucinations
- Agitation
- Hypotension
- Sedation
What to Do:
There is no specific antidote. Treatment is symptomatic and supportive. Gastric lavage may be considered. Maintain vital signs. Call 911 or Poison Control (1-800-222-1222) immediately.
Drug Interactions
Major Interactions
- Dopamine antagonists (e.g., phenothiazines, butyrophenones, thioxanthenes, metoclopramide): May reduce the efficacy of pramipexole.
- Cimetidine, Ranitidine, Diltiazem, Verapamil, Quinidine, Quinine: May decrease renal clearance of pramipexole, leading to increased plasma levels.
Moderate Interactions
- Sedatives, hypnotics, alcohol: Increased risk of somnolence and sudden sleep onset.
- Antihypertensives: Increased risk of orthostatic hypotension.
Monitoring
Baseline Monitoring
Rationale: Pramipexole is primarily renally excreted; dose adjustment is necessary in renal impairment.
Timing: Before initiation
Rationale: Risk of orthostatic hypotension, especially at treatment initiation and dose escalation.
Timing: Before initiation
Rationale: Risk of hallucinations, delusions, impulse control disorders, and psychosis.
Timing: Before initiation
Rationale: Although rare, retinal changes have been reported with dopamine agonists.
Timing: Before initiation (consider, especially if pre-existing conditions)
Routine Monitoring
Frequency: Regularly, especially during dose titration and if symptoms occur.
Target: Maintain stable blood pressure, minimize orthostatic drop.
Action Threshold: Significant symptomatic orthostatic hypotension (e.g., >20 mmHg systolic drop or >10 mmHg diastolic drop with symptoms) requires dose reduction or discontinuation.
Frequency: At each visit, inquire about new or worsening hallucinations, delusions, impulse control disorders (e.g., pathological gambling, hypersexuality, compulsive shopping, binge eating), or psychosis.
Target: Absence of new or worsening psychiatric symptoms.
Action Threshold: Emergence of significant psychiatric symptoms or impulse control disorders requires dose reduction, discontinuation, or psychiatric consultation.
Frequency: At each visit, inquire about excessive daytime sleepiness or sudden sleep attacks.
Target: Maintain alertness.
Action Threshold: Significant somnolence or sudden sleep attacks, especially while driving or performing hazardous activities, requires dose reduction or discontinuation.
Frequency: Regularly, to assess therapeutic efficacy and adjust dose.
Target: Improved motor function, reduced tremor, rigidity, bradykinesia.
Action Threshold: Lack of efficacy or emergence of dyskinesia may require dose adjustment or addition of other therapies.
Symptom Monitoring
- Orthostatic dizziness or lightheadedness
- Excessive daytime sleepiness or sudden sleep attacks
- Hallucinations (visual, auditory)
- Delusions or paranoid ideation
- Compulsive behaviors (e.g., gambling, shopping, eating, sexual urges)
- Nausea, constipation, dry mouth
- Dyskinesia (in Parkinson's patients)
- Peripheral edema
Special Patient Groups
Pregnancy
Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. Animal studies have shown developmental toxicity at doses higher than human therapeutic doses.
Trimester-Specific Risks:
Lactation
Pramipexole is known to inhibit prolactin secretion in humans and may inhibit lactation. It is unknown if pramipexole is excreted in human milk. Due to the potential for serious adverse reactions in a breastfed infant, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Pediatric Use
Safety and effectiveness in pediatric patients have not been established. Not recommended for use in children.
Geriatric Use
Clearance of pramipexole is reduced in elderly patients due to age-related decline in renal function. Dose adjustments are often necessary based on renal function. Elderly patients may be more susceptible to adverse effects such as hallucinations, orthostatic hypotension, and somnolence.
Clinical Information
Clinical Pearls
- Pramipexole is a non-ergot dopamine agonist, which may have a lower risk of fibrotic complications (e.g., pleuropulmonary fibrosis, retroperitoneal fibrosis, cardiac valvulopathy) compared to ergot-derived dopamine agonists.
- Patients should be warned about the potential for sudden sleep attacks, even without prior warning signs of drowsiness. This risk is higher with higher doses and in patients with pre-existing sleep disorders.
- Impulse control disorders (e.g., pathological gambling, hypersexuality, compulsive shopping, binge eating) can emerge or worsen during treatment. Patients and caregivers should be educated to recognize these behaviors.
- Dose titration should be gradual to minimize adverse effects, especially orthostatic hypotension and nausea.
- For RLS, taking the dose 2-3 hours before bedtime is crucial for optimal efficacy.
- Withdrawal symptoms (e.g., akinesia, insomnia, depression, sweating) can occur if the drug is discontinued abruptly, especially after high doses or prolonged treatment. Tapering is recommended.
Alternative Therapies
- For Parkinson's Disease: Levodopa/carbidopa, other dopamine agonists (e.g., ropinirole, rotigotine), MAO-B inhibitors (e.g., selegiline, rasagiline), COMT inhibitors (e.g., entacapone, opicapone), amantadine, anticholinergics.
- For Restless Legs Syndrome: Other dopamine agonists (e.g., ropinirole, rotigotine), alpha-2 delta ligands (e.g., gabapentin, pregabalin), opioids (for severe refractory cases).
