        faqs

        Frequently asked questions about Hypocyn (hypochlorous acid) dermal spray

        Can I use Hypocyn (hypochlorous acid) dermal spray if it's expired?
        If you're using Hypocyn (hypochlorous acid) dermal spray at home for an ongoing skin condition, don't use this medication if it's expired. Always check the expiration date of your medication before using it. Expired Hypocyn (hypochlorous acid) dermal spray might not work well and can raise your risk of an infection.
        Is Hypocyn (hypochlorous acid) dermal spray an antibiotic?
        No, Hypocyn (hypochlorous acid) dermal spray isn't an antibiotic. However, it does have antimicrobial properties. This means that it can stop the growth of microbes, such as bacteria, fungi, and viruses.
        Does Hypocyn (hypochlorous acid) dermal spray have alcohol in it?
        No, Hypocyn (hypochlorous acid) dermal spray doesn't contain any alcohol.
        What's the difference between Avenova and Hypocyn?
        Avenova and Hypocyn are both medications that contain hypochlorous acid, but they aren't the same. The main difference is that Hypocyn is used to prevent skin infections from small wounds, while Avenova is used in certain eye conditions that cause red, itchy, crusty eyes, such as blepharitis (inflamed eyelids). If you have questions on the difference between the two products, talk to your provider or pharmacist.
        What's the difference between Hypocyn (hypochlorous acid) dermal spray and povidone iodine?
        Hypocyn (hypochlorous acid) dermal spray and povidone iodine are both topical (on the skin) medications used to prevent skin infections. However, your provider might pick one over the other for you, depending on your wound and what other health conditions you might have. For example, povidone iodine might not be appropriate for people who have thyroid problems or wounds that cover larger areas of the body. Hypocyn (hypochlorous acid) dermal spray doesn't have these warnings and might be more appropriate in these cases. Your provider will let you know which medication is most appropriate for your wound.
