Actress Sarah Jessica Parker says she is "disappointed, saddened and deeply concerned" by the price hike of the EpiPen, and has cut ties with the company that makes the emergency allergy treatment.

Parker, whose 13-year-old son James has a severe peanut and hazelnut allergy, was part of a short campaign with pharmaceutical giant Mylan N.V., maker of the EpiPen.

The company is facing heated criticism about the average cost of the EpiPen climbing more than 600 per cent over the past decade.

Parker took to Instagram to distance herself from the company and urged it to "take swift action to lower the cost to be more affordable for whom it is a lifesaving necessity."

Instragram users commented on her post praising her.

@Sprdavey says "this is the proper way a celebrity can use their status to forward a cause. Bravo."

"Thank you for taking a stand on this. The greed shown by this pharmaceutical company is unparalleled. Hopefully it will not be mimicked. Having worked in schools with a high poverty rate, this disgusts me to no end" says @bookwormbarb.
