Chlorhexidine can cause a rare but serious allergic reaction that may be life-threatening. Get emergency medical help if you have signs of an allergic reaction: hives, severe skin rash; wheezing, difficult breathing; cold sweats, severe dizziness; swelling of your face, lips, tongue, or throat.
Stop using Hibiclens and call your doctor at once if you have:
severe burning, itching, or redness;
blistering or peeling;
swelling or severe skin rash; or
any other severe irritation of treated skin.
Less serious side effects are more likely, and you may have none at all.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
