Consumerist notes that the warning came after the FDA consulted 131 reports (many from 2012 and onward) through its Adverse Event Reporting System (FAERS) of “hypersensitivity reactions with serious outcomes” from popular products that help deal with acne, The products contained either benzoyl peroxide or salicylic acid.
Of these 131 reported incidents, 58 (44 percent) resulted in hospitalizations. Fifty of the incidents were described as involving anaphylactic hypersensitivity, meaning that there was some evidence of compromised respiratory or cardiovascular function, plus problems on the skin, like swelling or hives. These are far beyond the usual warnings on acne products, which mention the possibility of momentary irritation or redness.
What causes these reactions is currently unknown, as is how quickly one can expect a reaction if prone to one, as some reported problems after minutes of application and others days later. Almost 75 percent of those affected recovered somewhat after ceasing use of the acne product. The acne product could take a number of different forms like cleansing pads, face washes, lotions and gels.
The FDA says that if you experience any of the following symptoms of hypersensitivity, you should stop using the acne product:
- Throat tightness
- Difficulty breathing
- Feeling faint
- Swelling of the eyes, face, lips or tongue
- Development of hives
- Itching
