Guernsey's health department is urging all users or former users of a controversial cancer drug GcMAF to contact their GP.
The unlicenced drug has been banned after its UK factory closed amid fears materials used aren't fit for human consumption.
Hundreds of islanders have already pleaded with politicians and health officials to have the ban lifted.
Guernsey's Health Department has revealed it will consider recommending the licensing of alternative regulated sources of GcMAF.
GcMAF is a drug which Guernsey resident David Noakes claims treats conditions like cancer, HIV and autism. Mr Noakes owns a Guernsey company which makes the unlicensed drug. However two weeks ago his factory closed amid fears materials used aren't fit for human consumption.
Today, island health bosses have been told by the UK regulator, MHRA, that there are no alternative sources of GcMAF.
However, the medicines regulator, Chief Pharmacist, Ed Freestone, says he would be prepared to consider recommending the licensing of a product if it went through the necessary approvals and controls.
Guernsey's Health Department are asking anyone who wishes to import GcMAF, should make contact with the Chief Pharmacist to discuss their proposed importation, from an alternative source.
The weekend event coincides with International Pride Month and the 51st anniversary of the Stonewall riots.
The scheme has been backed by the island's Lieutenant-Governor, and is the first of its kind in the Channel Islands.
