We are having difficulty obtaining Lidocaine 2% mouthwash on prescription. Currently using Lidocaine Hcl with Hydrocortisone for pain relief but the hydrocortisone is possibly delaying healing of ulceration caused by chemoradiotherapy and have been told to use Lidocaine 2% mouthwash instead but can't get it. Just wondering if there are any alternative mouthwashes which help with severe pain caused by non healing ulceration in the throat please.
