What Is Requip and What Is It Used For?

Requip (ropinirole hydrochloride) is a non-ergoline dopamine agonist that directly stimulates dopamine D2 and D3 receptors in the brain. It is FDA-approved for two distinct neurological conditions:

  • Parkinson’s Disease – as monotherapy in early disease or adjunct to levodopa in advanced disease
  • Moderate-to-Severe Primary Restless Legs Syndrome (RLS) – significantly reduces uncomfortable leg sensations and urge to move

Mechanism of Action

Ropinirole preferentially binds D2 and D3 receptors in the striatum (Parkinson’s) and limbic system, restoring dopaminergic activity without the need for enzymatic conversion (unlike levodopa). In RLS, it modulates the dopaminergic deficit believed to underlie sensory-motor symptoms.

Side Effects and Safety Considerations

Common: Nausea (up to 60% initially), dizziness, somnolence, orthostatic hypotension
Serious: Impulse control disorders (gambling, hypersexuality), sudden sleep attacks, hallucinations (especially elderly), augmentation and rebound in RLS

Frequently Asked Questions (FAQ)

Yes – impulse control disorders occur in up to 17% of Parkinson’s patients on dopamine agonists. Stop immediately if noticed.

Most patients notice significant relief within 1–2 weeks at therapeutic dose (1–4 mg).

No – abrupt withdrawal can cause dopamine agonist withdrawal syndrome (anxiety, depression, pain). Taper slowly.

Immediate-release taken 1–3 hours before bed is usually preferred for RLS due to faster onset.

Patient Reviews (Verified Purchases)

“After 10 years of RLS misery, 2 mg at night changed my life. I finally sleep through the night.” – Karen M., 56
“Early Parkinson’s – started at 3 mg/day. Tremor almost gone, only mild nausea first week.” – John P., 63
“Switched from pramipexole because of augmentation. Requip XL 8 mg once daily works better.” – Susan L., 59
“RLS gone within 3 days at 1 mg. No more pacing at night!” – David R., 48
“Using for Parkinson’s + RLS combo. 4 mg XL in morning covers both all day.” – Margaret T., 71
“Took 2 weeks to titrate, but worth it. No more crawling sensation in legs.” – Lisa K., 52
“Genuine GSK product, fast shipping. Highly recommend.” – William H., 67
