It's surprisingly difficult.

Some drug side effects are pretty strange — so strange that it's hard to tell them apart from things that happen in fairy tales. See if you can tell whether each of the following is a known drug side effect, something unfortunate that befalls a fairy tale character, or both. (BuzzFeed gathered all side effects data from Drugs.com.)
Unusual hair growth is a side effect of the synthetic estrogen drug Delestrogen. It also happens to the prince in "Beauty and the Beast."
Believe it or not, this is a possible side effect of the anti-inflammatory drug Cortan.
Not a known side effect, but the Frog Prince does get green skin when a fairy curses him.
In the Brothers Grimm version of "Snow White," the queen is forced to dance in red-hot iron shoes until she dies.
A side effect of the acne drug Minocin.
In the Brothers Grimm version of Cinderella, the wicked stepsisters cut off pieces of their feet to fit into dainty shoes, and their feet bleed uncontrollably.
Sleepiness is a side effect of many drugs, including the malaria drug Lariam, and it of course also afflicts Sleeping Beauty.
Feeling threatened is a side effect of the drug Trilafon, used to treat nausea and some mental disorders.
The drug Rocaltrol, which treats low calcium, can cause patients to hear voices. In the Brothers Grimm story "The Singing Bone," a bone begins to sing by itself, shocking listeners.
In the old story "The Girl With the Green Ribbon," a girl's head falls off when the ribbon is untied. This is not a known side effect of any drug.
