It's generally considered poor practice to make multiple OSM elements for one thing.   So you should look for a variant tag that represents what you want.  In this case I've looked at the wiki for "opening_hours" and find a link to to "opening_hours:pharmacy" in the related tags.  I've added this tag.

I have little faith in opening_hours being updated for most businesses on OSM, so I've also tagged this with the link to Walgreen's page on this store, including all opening and pharmacy hours.
