How to Use This Medicine

Taking Your Medication

To get the most benefit from your medication, follow your doctor's instructions carefully. Read all the information provided with your medication and follow the instructions closely. You can take this medication with or without food. Swallow the tablet whole - do not chew, break, or crush it.

If you have a health condition like diarrhea that causes the medication to pass through your body too quickly, you may notice what looks like the tablet in your stool. If this happens, consult your doctor.

Continue taking your medication as directed by your doctor or healthcare provider, even if you start to feel well. If you need to stop taking the medication, talk to your doctor first. You may need to restart with a lower dose and gradually increase it.

Storing and Disposing of Your Medication

Store your medication at room temperature, away from light and moisture. Keep the container tightly closed and store it in a dry place, such as a closet or drawer. Do not store your medication in the bathroom. Keep all medications out of the reach of children and pets.

When you're finished with your medication or it's expired, dispose of it properly. Do not flush it down the toilet or pour it down the drain unless instructed to do so. Check with your pharmacist for guidance on the best way to dispose of your medication. You may also want to check if there are any medication take-back programs in your area.

Missing a Dose

If you miss a dose, take it as soon as you remember. If it's close to the time for your next dose, skip the missed dose and take the next one at your regular time. Do not take two doses at the same time or take extra doses. If you miss several days of medication, call your doctor for advice on how to restart your treatment.
💡

Lifestyle & Tips

  • Take the tablet whole; do not crush, chew, or divide it.
  • Can be taken with or without food, but taking with food may help reduce nausea.
  • Avoid sudden changes in position (e.g., standing up quickly) to minimize dizziness from low blood pressure.
  • Be aware of potential for sudden sleep attacks; avoid driving or operating machinery if you experience drowsiness.
  • Limit or avoid alcohol, as it can increase drowsiness.

Drug Interactions

🔴

Major Interactions

  • Dopamine antagonists (e.g., antipsychotics like haloperidol, phenothiazines, metoclopramide): May reduce the efficacy of ropinirole.
  • CYP1A2 inhibitors (e.g., ciprofloxacin, fluvoxamine): May significantly increase ropinirole plasma levels, increasing risk of adverse effects.
🟡

Moderate Interactions

  • Estrogens (e.g., hormone replacement therapy, oral contraceptives): May decrease ropinirole clearance, leading to increased plasma levels. Dose adjustment of ropinirole may be needed.
  • Other CNS depressants (e.g., alcohol, sedatives, hypnotics): May potentiate sedative effects.

Monitoring

đŸ”Ŧ

Baseline Monitoring

Blood pressure (sitting and standing)

Rationale: To assess for orthostatic hypotension risk.

Timing: Prior to initiation

Mental status/cognitive function

Rationale: To assess baseline for potential hallucinations, confusion, or impulse control disorders.

Timing: Prior to initiation

Parkinson's disease symptoms (e.g., UPDRS score)

Rationale: To establish baseline disease severity and track efficacy.

Timing: Prior to initiation

📊

Routine Monitoring

Blood pressure (sitting and standing)

Frequency: Regularly, especially during dose titration and if symptoms of orthostatic hypotension occur.

Target: Maintain within patient's normal limits, monitor for significant drops.

Action Threshold: Symptomatic orthostatic hypotension or sustained drop >20 mmHg systolic or >10 mmHg diastolic.

Efficacy (motor symptoms, 'off' time)

Frequency: At each visit, especially during titration.

Target: Improved motor control, reduced 'off' time.

Action Threshold: Lack of improvement or worsening symptoms may indicate need for dose adjustment or alternative therapy.

Adverse effects (e.g., somnolence, hallucinations, dyskinesia, impulse control disorders)

Frequency: At each visit.

Target: Absence or minimal, tolerable side effects.

Action Threshold: Development of severe or intolerable side effects (e.g., sudden sleep attacks, vivid hallucinations, compulsive behaviors) requiring dose reduction or discontinuation.

Mental status/behavioral changes

Frequency: Regularly, inquire about new or worsening compulsive behaviors (gambling, hypersexuality, shopping, eating).

Target: Stable mental status and behavior.

Action Threshold: New onset or worsening of impulse control disorders or psychotic symptoms.

đŸ‘ī¸

Symptom Monitoring

  • Orthostatic hypotension (dizziness, lightheadedness upon standing)
  • Somnolence/sudden sleep attacks
  • Hallucinations (visual, auditory)
  • Dyskinesia (involuntary movements)
  • Nausea/vomiting
  • Peripheral edema
  • Impulse control disorders (pathological gambling, hypersexuality, compulsive shopping/eating)
  • Confusion/psychosis

Special Patient Groups

🤰

Pregnancy

Category C. Use only if the potential benefit justifies the potential risk to the fetus. Animal studies have shown adverse effects on embryo-fetal development at doses higher than human therapeutic doses.

Trimester-Specific Risks:

First Trimester: Potential for developmental toxicity observed in animal studies.
Second Trimester: Potential for developmental toxicity observed in animal studies.
Third Trimester: Potential for developmental toxicity observed in animal studies; may inhibit lactation.
🤱

Lactation

Ropinirole is excreted in human milk and may inhibit lactation due to its dopamine agonist activity. 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.

Infant Risk: Risk of somnolence, feeding difficulties, and potential inhibition of lactation in the infant. Avoid use if possible.
đŸ‘ļ

Pediatric Use

Safety and effectiveness in pediatric patients have not been established. Not indicated for use in this population.

👴

Geriatric Use

No overall differences in safety or effectiveness were observed between elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Start with lower doses and titrate slowly due to increased risk of hallucinations and orthostatic hypotension.

Clinical Information

💎

Clinical Pearls

  • Ropinirole ER is typically taken once daily. Emphasize not to crush, chew, or divide the tablets.
  • Warn patients about the potential for sudden sleep attacks without warning, even during daily activities. Advise caution with driving or operating machinery.
  • Educate patients and caregivers about impulse control disorders (e.g., pathological gambling, hypersexuality, compulsive shopping/eating) and to report any new or worsening behaviors.
  • Orthostatic hypotension is a common side effect, especially during initiation and dose titration. Advise patients to rise slowly from a sitting or lying position.
  • Hallucinations are more common in elderly patients and those with advanced Parkinson's disease. Monitor for these symptoms.
  • Nausea can be managed by taking the medication with food, though it's not strictly required.
  • Dose titration is crucial for managing efficacy and minimizing side effects. Patients should be advised to follow the prescribed titration schedule carefully.
🔄

Alternative Therapies

  • Other dopamine agonists (e.g., pramipexole, rotigotine)
  • Levodopa/carbidopa
  • MAO-B inhibitors (e.g., selegiline, rasagiline, safinamide)
  • COMT inhibitors (e.g., entacapone, opicapone)
