What is GelX®?

GelX® is an oral spray, designed to protect the mucous membranes within the mouth. It is indicated for the prevention and treatment of oral mucositis and is suitable for use in all ages and all ethnic cultures. 1

How it works

GelX® works by providing a barrier to protect oral membrane tissue. It blocks exposed nerve endings and coats oral lesions to soothe and relieve pain.1,4 This helps patients to cope with oral mucositis and to complete long-term treatment goals.5

Think you have oral mucositis?

Trusted by patients & healthcare professionals…

I started using GelX after 1 cycle of chemotherapy. I had already started with a number of large mouth ulcers and was finding eating and swallowing painful. After just 2 days of using GelX, no further ulcers appeared. Throughout my chemo treatments I only had a handful of small ulcers. I can wholeheartedly say that GelX has made a significant difference to my oral comfort and enabled me to eat more normally than I could have done…A truly wonderful product!

Jayne, Patient, Wrexham

I was kindly sent GelX at the beginning of my throat cancer journey. During treatment this was a fantastic product that enabled me to have a life. Eating, drinking, smiling - GelX played a big part. I would 100% fully recommend this product to anybody without hesitation.

Jon, Patient, Surrey

I support patients with Head and Neck cancers and have found, since the introduction of GelX during radiotherapy (with or without chemotherapy), mucositis is reduced. This has meant for some patients, stronger analgesics have not been necessary or at least not required so early on during their course of radiotherapy. We find using GelX prophylactically in Head and Neck cancer patients, receiving radiotherapy, helps reduce the severity of mucositis.

Head & Neck Specialist Radiographer, Kent

We have been using GelX for about a year now. Mucositis has been improved in patients who use it consistently from the beginning of treatment.
