Side effects of iodine glycerin

Iodine glycerin may cause allergic reactions as a side effect.

Iodine glycerin is a topical dermatological agent clinically used to treat conditions such as gingivitis, pericoronitis, and oral mucosal ulcers. Adverse effects are generally rare; however, in patients with heightened sensitivity, allergic reactions may occur, manifesting primarily as erythema, pruritus, or a burning sensation at the application site. If an allergic reaction develops, discontinue use immediately and thoroughly wash off the medication from the affected area. When necessary, antihistamines—such as cetirizine hydrochloride or loratadine—may be administered orally under a physician’s guidance to alleviate symptoms.

Iodine glycerin functions as a disinfectant and antiseptic by denaturing microbial proteins, thereby causing microbial death. It exhibits broad-spectrum antimicrobial activity against viruses, bacteria, and fungi. However, if symptoms fail to improve or worsen—or if new abnormal symptoms emerge—within five days of treatment, prompt medical consultation is advised.
