Indications
Chlorhexidine Hydrochloride is an antiseptic used on the skin, usually in creams and lotions, often together with other antiseptics such as Cetrimide or with moisturising ingredients. It is used:
- to clean and help prevent infection in minor cuts, grazes, scratches and small burns or scalds;
- for nappy rash and sore, cracked skin where infection is a risk;
- in moisturising (emollient) products for dry, itchy or eczema-prone skin that tends to become infected.
How It Works
Chlorhexidine attaches to the outer wall of bacteria and damages it, so the bacteria die or stop growing. It works against many common skin bacteria and some fungi, and it stays on the skin for a while after use.
Dosage and Administration
For external use only. Clean and gently dry the area, then apply a thin layer one to three times a day, or as directed on the product label. Emollient products may be used more often, as the label advises. A clean dressing may be placed over a wound if needed.
If a minor wound or rash does not improve within a few days, see a doctor.
Interactions
Soap and some other skin products can reduce how well chlorhexidine works; rinse the skin well before applying. Avoid using different antiseptics on the same area at the same time unless advised. Tell your doctor or pharmacist about any other skin products you use.
Contraindications
- Allergy to chlorhexidine or any ingredient of the product
- Not for use in the eyes, inside the ears, or on deep or large wounds
Side Effects
Side effects are uncommon. Some people get redness, stinging, dryness or itching where it is applied.
Rarely, chlorhexidine can cause a serious allergic reaction. Stop using it and get medical help at once if you have hives, swelling of the face, lips or throat, wheezing or difficulty breathing, or feel faint.
Pregnancy and Lactation
Use on small areas of skin is not expected to cause harm in pregnancy or while breastfeeding. Do not apply to the breasts just before feeding; if it has been used there, wash it off before the baby feeds.
Precautions and Warnings
- If it gets into the eyes, rinse well with clean water at once and seek advice if irritation continues.
- Use with care on newborn and premature babies, whose skin is more sensitive.
- Serious burns, deep cuts, animal bites and wounds with signs of infection (spreading redness, pus, fever) need a doctor.
- Fabrics that have touched chlorhexidine can stain brown if washed with bleach.
Overdose
Overuse on the skin is unlikely to be harmful. If a large amount is swallowed, it may cause stomach upset; contact a doctor for advice.
