Bromocriptine for RLS

Clinical bottom line

There is no evidence from a small trial in six patients that bromocriptine is of any value in RLS.


Reference

AS Walters et al. A double-blind randomized crossover trial of bromocriptine and placebo in restless legs syndrome. Annals of neurology 1988 24: 455-458.

Clinical trial

This tiny trial involved six patients treated with bromocriptine and placebo in two 30-day periods separated with two weeks without drug. Outcomes were mainly sleep studies.

Results

The details are in Table 1. There were some small differences in sleep, and RLS symptoms, though the latter are not well described.
