RLS-UK has been in contact with GlaxoSmithKline (GSK) regarding Ropinirole, which GSK manufacture.
There is a problem with the distribution of Ropinirole on the lower 0.5mg tablet which means it is often unavailable. However, you may still find it at an independent chemist.
If you are unable to find the 0.5mg dosage your doctor may prescribe 2 x 0.25mg.
It might be prudent to raise this issue with your doctor if you are on a 0.5mg prescription so to ensure you get a correct prescription at the time of your appointment (rather than having to go back again for a new prescription if your chemist cannot issue 0.5mg tablets due to the short supply)
GSK are unable to advise when the the current issues will be resolved with the 0.5mg tablet.
