Walgreens misfills prescriptions and this not only causes problems for Walgreens but for individuals injured as a result of prescription filling errors. Pharmacies and pharmacists elsewhere have had some similar problems, but as far as I am aware they don't try to cover up the extent of the problem. Yesterday, I was called by a personal injury lawyer helping someone who badly harmed as a result of Walgreens pharmacy errors and I could not help much because a court order prevents me from releasing what I learned.
