What Is Ropinirole?

Ropinirole, previously sold under brand names Requip and Requip XL, is a non-ergoline dopamine agonist used to treat the symptoms of Parkinson’s disease and restless legs syndrome (RLS).

Ropinirole acts on the nervous system at dopamine receptors (a neurotransmitter or a chemical messenger). It stimulates the dopamine receptors that help restore the balance of natural dopamine in the brain needed to control movements.

This medication is available as immediate-release and extended-release tablets.

What Is Ropinirole Used For?

The Food and Drug Administration (FDA) approved ropinirole for use alone or with other medicines to treat Parkinson’s disease, a condition associated with low dopamine levels in the brain. It acts at dopamine receptors and has the same effects as naturally occurring dopamine.

Nearly one million people in the United States are currently living with Parkinson’s, and about 60,000 Americans are diagnosed with the condition each year.

Symptoms often include, but are not limited to:

  • Tremors
  • Slowed movement
  • Stiffness
  • Imbalance

In Parkinson’s disease, ropinirole helps to improve movement and reduce tremors, stiffness, and poor muscle control.

It is also used to treat restless legs syndrome, a condition causing a strong urge to move the legs, often worsening at rest and bedtime.

How to Take Ropinirole

Read the patient information leaflet before you start ropinirole. Consult your healthcare provider or pharmacist if you have any questions about the treatment.

For Parkinson’s disease, ropinirole is available in immediate-release (IR) or extended-release (ER) tablets. If prescribed the IR tablets, you will usually take them three times a day. The ER pills are usually only taken once daily.

Take the tablet by mouth, with or without food. Taking your dose with food may help decrease nausea or stomach upset. Swallow the tablet whole; do not crush or chew the ER tablets. Doing so can release the drug all at once, increasing the risk of side effects.

The ER tablets are not prescribed for restless leg syndrome. For the immediate-release tablets, take them once a day, one to three hours before bedtime.

Your prescribed dose will depend on your medical condition and response to treatment. Your healthcare provider may start you at a low dose and gradually increase it to reduce the risk of side effects. Make sure to follow your provider’s instructions carefully.

It is important to remember that ropinirole improves the symptoms of Parkinson’s disease and restless legs syndrome but does not cure them. Do not stop taking it without consulting your healthcare provider, even if you feel better. Sudden discontinuation may cause withdrawal symptoms (such as fever, muscle stiffness, and confusion). Your provider may lower the dose slowly to help prevent withdrawal symptoms.


Keep the tablets in a tightly closed container with the desiccant, if provided. Store it at room temperature, away from sunlight, heat, and moisture. Keep all the medicines out of sight and reach of children. Do not store it in the bathroom.

Do not keep or use any expired medicines. Never discard unused or expired medicines down the drain, flush them in the toilet, or throw them in the garbage. Instead, the best way is to consult your pharmacist to return your medication through a medicine take-back program.

How Long Does Ropinirole Take to Work?

Ropinirole reaches the peak plasma concentration within one to two hours, but it takes around two days of regular dosing to attain stable blood levels in the body. The symptoms may start to improve after taking the first dose, but it can take up to one week to have its full effect.

What Are the Side Effects of Ropinirole?
