CVS has unveiled a new app that makes it easier for consumers to get long-term prescriptions.

Instead of calling the pharmacy for a refill or even driving there to get it you can now scan the bar code on your CVS prescription for an instant refill.

The pharmacy then fills a 90-day supply of the medicine, rather than the usual 30-day supply.

The app also allows customers to check for potential drug interactions and identify pills that have been taken out of their original packaging.
