Whanganui pharmacies are now offering those with a respiratory illness a free spacer device.
This will benefit those who are prescribed an aerosol inhaler such as Ventolin, Seretide and Flixotide.
Des Healy, a pharmacist with the Whanganui Regional Health Network, said spacer devices could improve the delivery of the medicine to get deep into the smallest airways where inflammation and constriction exists.
"It's especially important when challenged with a viral infection. Now is the time when all patients with a respiratory illness need to manage their condition as well as possible."
