Other specific side effects (adverse events) for prescription drugs used to treat moderate to severe RLS symptoms are listed in the table below. Table: Evidence for Prescription Drug Treatments for Moderate to Severe RLS Symptoms Prescription Drug Strength of Evidence* Conclusion/Recommendation Adverse Events (AEs) First-line management options include iron-replacement therapy in those with evidence for reduced body-iron stores or, alternatively, with prescribed gabapentin or pregabalin, and dopamine agonists such as pramipexole, ropinirole, and rotigotine.

A randomized, double-blind, placebo-controlled study to assess the efficacy and tolerability of gabapentin enacarbil in subjects with restless legs syndrome. J Clin Sleep Med. 2011;7(3):282-292. Walters AS, LeBrocq C, Dhar A, et al; International Restless Legs Syndrome Study Group. Gabapentin The use of gabapentin for restless legs syndrome (RLS) is off-label. Initial dose: 300 mg if the person is under 65 years old and 100 mg if the person is over 65 years old. Titration: maximum recommended dose for RLS is 2700 mg. CKS did not identify any specific guidance on dose titration for use in RLS. However, for other For restless legs syndrome: Adults—600 milligrams (mg) as a single dose at about 5 PM. Your doctor may adjust your dose as needed and tolerated. Children—Use and dose must be determined by your doctor. For postherpetic neuralgia: Adults—At first, 600 milligrams (mg) once a day taken in the morning for 3 days. Objective: To assess the effects of gabapentin on sensory and motor symptoms in patients with restless legs syndrome (RLS). Methods: Patients with RLS (22 idiopathic, 2 secondary to iron deficiency) were randomized and treated for 6 weeks with either Gabapentin’s effectiveness for RLS may take weeks, with dosage ranging from 300 mg to 3,600 mg daily. It’s initiated at a low dose and increased gradually. Continuity in usage is crucial, as full effects may take up to four weeks. Gabapentin has common side effects and rare serious reactions. Detailed dosage guidelines and administration information for Horizant (gabapentin enacarbil). Includes dose adjustments, warnings and precautions. Bottom Line: Gabapentin, in dosages of about 1,800 mg per day, was more effective than placebo in diminishing some symptoms of RLS. Side effects, although not major, occurred in about one half of e2 Allen RP, Walters AS, Montplaisir J, et al. Restless legs syndrome prevalence and impact: REST general population study.

Gabapentin enacarbil is a prodrug of gabapentin, converted to gabapentin after absorption, and thus avoids the nonlinear pharmacokinetics of gabapentin. It is administered as a single daily dose of 600 mg (300 mg in patients older than 65 years) at 5 pm to target adequate therapeutic levels at bedtime. Keywords: restless legs syndrome, gabapentin, gabapentin enacarbil, treatment. Background. Restless legs syndrome (RLS) is a movement disorder that affects between 5% and 10% of adults [Hening et al. 2004; Phillips et al. 2000; Lavigne and Montplaisir, 1994]. Gabapentin enacarbil available under the trade name Horizant is the only gabapentin product approved for treatment of Restless Legs Syndrome (RLS). A daily dose of 1200 mg provided no additional benefit compared with the 600 mg dose, but caused an increase in adverse reactions. When used for RLS, it can be taken as needed in 100-mg to 300-mg doses, with a maximum daily dose of 1800 mg. As with any drug, gabapentin can cause side effects. Many are relatively mild and transient, easing as your body adapts to treatment, while others may be longer lasting. Some people may experience no side effects at all. Gabapentin enacarbil may have two distinct therapeutic doses for the treatment of RLS: 600 mg/day or lower doses for the treatment of subjective RLS symptoms and 1,200 mg/day or higher doses for the treatment of both subjective RLS symptoms and associated problems such as severe sleep disturbances. Officially confirmed augmentation from ropinirole usage. The RLS controls my life 7 days a week. Symptoms start as early as 1-2 pm. Afternoons are something I just try to get through until bedtime. I take ropinirole 2 mg per day total in divided doses; 1/2 mg at b/t 12-2 pm, 1 mg at 7 pm, and 1/2 mg around 12 midnight to get through the night. The use of gabapentin for restless legs syndrome (RLS) is off-label. Initial dose of 300 mg if the person is under 65 years old and 100 mg if the person is over 65 years old. Maximum recommended dose for RLS is 2700 mg. CKS did not identify any specific guidance on dose titration for use in RLS.
