An absolutely crazy out of Spain. 

Parents looking to solve their babies indigestion problems ended up with werewolf babies instead. 

The formula that the babies were given was actually tainted with medicine to help treat alcopecia, a hair loss condition. 

From the New York Post story:

"The indigestion medication, omeprazole, was made by Farma-Química Sur, and was part of a formula for babies. Spanish health officials say the medicine was contaminated at its source in India. They learned of the contamination when 13 parents came forward to report the hair-growth symptoms in July, followed by three more last month."

Farma-Quimica Sur has had their liscene taken away since the revelation.
