Thanks to Darren Awender, Walgreen's pharmacist at 8030 N. 19th Avenue, I was cautious about deciding to use a medication prescribed to me. Its second ingredient was a sulfa product, something I am allergic to. Thanks to this pharmacist's comment, I chose not to use a product that would have harmed me. Cannot thank this individual enough, who simply responded "That's my job. That's what I am here for." . . . truly grateful is what I feel.
