Update- there is a coupon available for Proventil HFa which some can use instead.
HERE
I checked the GlaxoSmithKline website
Information to Save on Prescriptions at GSKForYou.com
This coupon no longer appears to be available from their website.
They are only showing coupons for the following medications:
ADVAIR DISKUS®(fluticasone propionate and salmeterol inhalation powder)
LAMICTAL® (lamotrigine)
LAMICTAL®XRTM (lamotrigine extended-release tablets)
Lovaza® (omega-3-acid ethyl esters)
TreximetTM (sumatriptan / naproxen sodium)
Veramyst® (fluticasone furoate)
VESIcare®* (solifenacin succinate)
Unfortunately Ventolin is not one of them.
