Anyone know what this is likely to be.
It will be the Generic Sildenafil.
I spoke to my GP late last year asking about getting my prescription for Sildenafil switched to Avanafil and was told the NHS is stopping prescribing all ED tablets bar generic Sildenafil as its so much cheaper for the NHS.
If you are wanting Cialis on the NHS you will need to get it on a private prescription for £25-£30 for 4x20mg tablets.
*Edit* If its only a local thing, then I will say I am in Newcastle.
