Topical: Topical use only; not for ophthalmic, oral, or intravaginal use. Avoid application to open wounds or unaffected skin. Wash hands prior to use. Berdazimer is supplied in two tubes that must be mixed using the supplied dosing guide card just prior to each application; do not mix directly on skin or in palm of hand; do not premix. Squeeze contents of tube A (blue) to cover entire blue dosing line, then squeeze contents of tube B (yellow) to cover entire yellow dosing line on dosing guide. Wipe any excess gel that leaks from tubes with a tissue or cloth; ensure the correct cap is replaced on the coordinating colored tube. Using fingertips, mix the two gels together in the center of the dosing guide using a swirling motion while slowly counting to 20. Some clumps may occur during mixing, which is normal. Immediately after mixing, apply mixed gel to all molluscum bumps (lesions), paying particular attention to new, hard-to-reach, or hard-to-see areas. If gel runs out before all affected areas are covered, wipe dosing guide with a dry tissue and repeat mixing process. Wash hands after application, except for areas on hands that are being treated. Wait 10 minutes after application before putting on clothes to allow the gel to dry. Wait at least 1 hour after application before swimming, showering, bathing, or washing. After all areas are treated, wash dosing guide with mild soap and water and dry.
Topical: For topical use only; not for intravaginal, ophthalmic, or oral use. Mix together equal amounts of gel from tube A and tube B on the dosing guide (do not mix directly on skin or in palm of hand) immediately prior to applying; do not premix. Wipe any excess gel that leaks from tubes with a tissue or cloth; ensure the correct cap is replaced on the coordinating colored tube. Apply an even, thin layer to clean, dry skin. After applying, allow gel to dry for 10 minutes before covering with clothes. Do not apply to open wounds. Avoid applying to uninvolved skin or transferring to other areas, including the eye. Do not bathe, shower, swim, or wash for 1 hour after application. Wash hands before and after use, unless hands are being treated. Discard any amount not used; do not store for later use. Clean dosing guide with mild soap and water after use.
Prior to dispensing, store between 2°C and 8°C (36°F and 46°F). After dispensing, store between 20°C and 25°C (68°F and 77°F). Do not freeze and keep away from open flame. Discard any amount not used 60 days after removal from the refrigerator.
