Benzalkonium chloride is an active ingredient in over-the-counter medication approved by the U.S. Food and Drug Administration (FDA) to treat inflammation and irritation of the skin. Benzalkonium chloride is sometimes used to treat people with hidradenitis suppurativa (HS).
The most common brands of benzalkonium chloride used to treat HS include Bactine and Neosporin. Benzalkonium chloride can help fight HS by disinfecting flare-ups on the skin to reduce inflammation.
How do I take it?
In cases of HS, benzalkonium chloride should be applied to the affected skin surfaces. Follow directions on the label to determine dosage and frequency of treatment. As with all over-the-counter medications, make sure to ask your doctor before beginning treatment.
Common side effects of benzalkonium chloride include a mild stinging sensation when first applied.
Rare but serious side effects caused by benzalkonium chloride include allergic reactions like skin rash, itching or hives, swelling of the face, lips, or tongue; chemical burn; and skin irritation like redness, itching, or stinging that does not go away.
