Hospital only drug Ireland

I've been taking a new medication while in hospital but it's been classed as a hospital only drug. Now I've been discharged, insurance will no longer cover it and it's not covered by any DPS scheme so it's over €1k a week for the drug which I obviously can't afford amd I'm going to really suffer without it! 😔 If anyone has any idea how I'd go about getting this as a reimbursable drug I'd appreciate any insights!!
