Hello My 84 year old mum was given an injection of Prolia on the 18th November last . her face started itching badly 36 hours later especially along and slightly under her jaw-line. Anti-histamines have not helped She informed her GP of this itching 25th November and asked if it could be down to the Prolia but her GP dismissed the idea suggesting that it is something she is using i.e washing powder, skin products, food etc but Mum has not changed anything at all Mum also aske dabout being referred to a dermatologist or having blood tests or allergy tests carried out and all of these were again dismissed by her GP. The itching is no better. she took it upon herself to see another doctor who carries out allergy testing but as soon as he learned Mum had been given Prolia he told her that this was the cause of her itching and that a low dose of steroids would ease it for her. However it would take up to 5/6 months for the Prolia to leave her system. She is very distressed and getting very little sleep. Since Friday the itch has become more aggressive with splotchy red itchy pimples appearing on her forearms. She is now doubting the doctor s diagnosis that it is the Prolia causing the itch. because it is worse...is that normal...?. She started on 30mgs of Deltacortril this morning I would appreciate any opinion you have regarding this. Kind regards Catherine Foley
