The move to hire PR help was prompted by a decision by NICE to allow the cost of measurement strips for the device to be claimed on the NHS, reducing the expense to patients.
The product currently retails at £400, and is aimed at patients who wish to avoid the regular medical consultations involved in monitoring anti-coagulation therapy by enabling them to assume control of their own condition management.
Red Door director Julia Tollis heads the agency's work on the account reporting to Alison Macgee, head of PR and communications for CoaguChek S patient monitoring.
The agency was hired following a three-way selection process and the campaign is part of a £1m spend across comms disciplines to support the product.
Tollis said the campaign would focus on patient awareness work: 'It's the first product of its kind and it will make a huge difference to the quality of life and independence of people who have to go to clinics regularly.
'We'll be looking to ensure that people are aware of the product and whether or not it is suitable for them,' she added.
