Chlorhexidine gluconate is an antiseptic that kills bacteria on skin and mucous membranes and keeps working for some hours after it is applied. That lasting action is why it is the standard scrub before surgery and a common mouthwash ingredient.

What Chlorhexidine Gluconate Is Used For

  • Cleaning skin before injections, procedures and surgery
  • Cleaning minor wounds, cuts and grazes
  • Mouthwash for gum inflammation and mouth ulcers
  • Hand disinfection in clinical settings

Common Side Effects

  • Skin dryness or irritation
  • Brown staining of teeth with prolonged mouthwash use
  • Temporary change in taste
  • Burning sensation on broken skin

Precautions

Keep it away from the eyes and ear canal. Mouthwash is meant for short courses of one to two weeks, because longer use stains teeth and dulls taste, and it should not be used straight after brushing since toothpaste blocks its action. Allergic reactions are rare but can be severe, so stop if a rash or swelling appears.
