Britain could lose parts of Ireland including the hard-hit western part of the island due to a large-scale increase in the use of pain medication the health minister said on Tuesday.

Health minister Matt Hancock said that some personal-use palliative medicines for patients with chronic ailments would be promoted to help ease the emotional impact of having missed out on a major global health material.

Health Minister Matt Hancock said that the Royal College of General Practitioners had announced the deal with the public health authority saying it would label it a step forward. He added that as part of the scheme branded compounds would be available in pharmacies.

Over the last few months the use of these branded compounds by patients with chronic cough and cold nausea and stress has grown significantly. I am asking the RCDR and the public health authority to agree that we may lose some of the parts of Ireland that remain in our possession Hancock said.

Borders are being blurred with some states in the south of England allowing some palliative drugs to be used and others not while others in the north including Dublin are deciding whether they should be promoted.

The RCDR has said that patients will still need to visit health authorities in their area to fill prescriptions required for treatment of specific diseases when their conditions are calming. The British hours for fill prescriptions are 19:00-20:30 GMT on Thursday.

Palliative drugs which can treat serious diseases including cancer and advanced Alzheimers disease can be effective in helping patients manage their final stages of the illness.

The social influence of pain has previously been shown to increase hospital stay by 3 and the rate of overdose deaths has fallen by 95.

Anyone who needs help to manage their pain should see a doctor the Royal College of General Practitioners said last month.

Palliative drugs have been found to be effective in treating patients with moderate to severe forms of pain the RCDR added.
