  • Therapeutic Indications


    Moderate to severe idiopathic Restless Legs Syndrome: Symptomatic treatment
    Parkinson's disease



    Individual dose titration against efficacy and tolerability is recommended.

    Parkinson's Disease
    The initial dose should be 250 micrograms three times daily. A guide for titration is given below:

    Week 1: 250 micrograms three times daily
    Week 2: 500 micrograms three times daily
    Week 3: 750 micrograms three times daily
    Week 4: 1mg three times daily
    Increase in weekly increments as necessary from 1.5 to 3mg/day.

    If using the 'follow on' pack follow the proposed titration regime:
    Week 5: 1.5mg three times daily
    Week 6: 2mg three times daily
    Week 7: 2.5mg three times daily
    Week 8: 3mg three times daily.

    Therapeutic responses are usually seen in doses of 3mg to 9mg daily, adjunct therapy may require higher doses.
    If sufficient symptomatic control is not achieved or maintained, the dose may be increased until an acceptable therapeutic response is established.

    The maximum dose is 24mg daily.

    Ropinirole is usually given in divided doses three times a day with meals in order to improve gastrointestinal tolerance.

    Restless Legs Syndrome (RLS)
    The recommended initial dose is 250 micrograms once daily for 2 days. If the dose is well tolerated, the dose should be increased to 500 micrograms once daily for the duration of week 1.

    In week 2, the dose may be increased to 1mg once daily. Then over the next 2 weeks the dose may be increased by 500 micrograms per week to a dose of 2mg daily until optimal improvement is achieved. The maximum daily dosage is 4mg once daily. The average dose is 2mg once daily.

    The patient's response should be evaluated after 3 months treatment, and the dose prescribed and need for continued treatment considered. If treatment is interrupted for more than a few days it should be re-initiated by dose titration.

    Ropinirole should be taken just before bedtime, and may be taken with food up to 3 hours before retiring in order to improve gastrointestinal tolerance.

    Patients with Renal Impairment

    Parkinson's disease
    In patients with end stage renal disease (those on haemodialysis), the recommended initial dose is 250 micrograms three times daily, with further dose escalations based on tolerability and efficacy with a maximum recommended dose of 18mg/day.

    Restless Legs Syndrome (RLS)
    In patients with end stage renal disease (those on haemodialysis), the recommended initial dose is 250 micrograms once daily, with further dose escalations based on tolerability and efficacy with a maximum recommended dose of 3mg/day.

    Additional Dosage Information

    Switching treatment
    When switching treatment from another dopamine agonist to ropinirole the manufacturer's guidance on discontinuation should be followed before initiating ropinirole.

    Parkinson's Disease
    When ropinirole is administered as adjunct therapy to levodopa, the concurrent dose of levodopa may be reduced gradually by around 20% in total.

    Hepatic impairment
    Renal impairment - creatinine clearance below 30 ml/minute

    Patients and carers should be made aware that symptoms of mania can occur with or without the symptoms of impulse control disorders in patients treated with ropinirole.

    Pregnancy and Lactation


    Use ropinirole with caution in pregnancy.

    Parkinsonism is mainly seen in older patients, and is not normally a disease in pregnant women. For Restless Leg Syndrome better-evaluated drug groups should be used.

    It is not known whether ropinirole can cross the human placenta. The molecular weight of about 260 for the free base, and the moderate degree of protein binding suggest it will cross over to the embryo and foetus. The lack of human data prevents an assessment of the human risk. The manufactures suggests ropinirole is not used during pregnancy unless the potential benefit to the patient outweighs the potential risk to the foetus . Schaefer (2015) states that inadvertent use of this drug does not justify the termination of pregnancy, nor does it justify invasive diagnostic procedures. A detailed foetal ultrasonography may be considered.

    Reproduction studies have revealed embryo-foetal toxicity and teratogenicity in pregnancy rats and rabbits. Decreased foetal weight, increased foetal deaths and digital formations were seen in rats when given 24, 36 and 60 times, respectively, the maximum recommended human clinical dose. No harmful effects were observed when ropinirole was given to pregnant rabbits at a maternal toxic dose 16 times the maximum recommended human dose based on BSA (MRHD). However, when ropinirole (at 8 times the MRHD) was administered with levodopa, an increased incidence and severity of foetal malformations (primarily digit defects) occurred than when levodopa was used alone.

    The use of all medication in pregnancy should be avoided whenever possible; particularly in the first trimester. Non-drug treatments should also be considered. When essential, a medication with the best safety record over time should be chosen, employing the lowest effective dose for the shortest possible time. Polypharmacy should be avoided. Teratogens taken in the pre-embryonic period, often quoted as lasting until 14 to 17 days post-conception, are believed to have an all-or-nothing effect. Where drugs have a short half-life, and when the date of conception is certain, this may allow women to be reassured where drug exposure has occurred within this time frame.

    Ropinirole is contraindicated during breastfeeding.

    At the time of writing there is limited published information regarding the use of ropinirole during breastfeeding. Animal studies of ropinirole-related materials have demonstrated transfer into the breast milk of rats. It is unknown if ropinirole is excreted in human breast milk. The effects of exposure on the breastfed infant are unknown. Ropinirole is known to suppress prolactin levels and would therefore be likely to lower milk production in breastfeeding mothers.

    The manufacturers do not recommend using ropinirole during breastfeeding.

    Neonates, infants born prematurely, those with low birth weight, those with an unstable gastrointestinal function or who have serious illnesses may require special consideration. For any infant, if a drug is prescribed to the nursing mother, it should be at the lowest practical dose and for the shortest time. When drug administration is unavoidable and breastfeeding is to continue, minimisation of exposure of the infant to the drug may sometimes be achieved by timing the maternal doses to just after a feeding episode. Infants exposed to drugs via breast milk should be monitored for unusual signs or symptoms. Interactions between the drug received by the infant from the mother's milk and medication prescribed for the infant should also be considered, for example, when the drug given to the infant may prevent metabolism of the drug received via breast milk.

    Withdrawal Symptoms and Signs

    Dopamine agonist withdrawal syndrome can occur when discontinuing ropinirole. Such symptoms include: apathy, anxiety, depression, fatigue, sweating and pain and do not respond to levodopa.

    Prior to ropinirole discontinuation, patients should be counselled regarding potential withdrawal symptoms. When ropinirole treatment is being discontinued, it is advisable to taper the dose gradually by reducing the number of daily doses over a period of one week, to minimise symptoms of withdrawal. In the event of severe and/or persistent withdrawal symptoms, consideration may be given to temporarily re-administer ropinirole at the lowest effective dose.


    It is strongly recommended that the UK National Poisons Information Service be consulted on cases of suspected or actual overdose where there is doubt over the degree of risk or about appropriate management.
