Ask for Cath Dry from your GP or clinician
Cath Dry dressings serve as both the dressing and a water-resistant cover that improve quality of life for patients. Ask your clinician of GP for Cath Dry by name or by NHS drug tariff code CDSS001 (21cm) or CDSS01XL (31cm). Or complete the request here and we will make the request on your behalf.
Cath Dry’s primary function is protecting against infection – but it also enables patients to shower, swim or continue watersports with minimum fuss and maximum protection.
The dressings were developed by a nephrology physician in the United States, where they are also widely available. Read more.
