chlorhexidine dihydrochloride + neomycin: clinical details
Prescribing considerations
- Confirm that treatment is for nasal staphylococcal infection, carriage or licensed prophylaxis.
- Use only nasally and avoid the eyes and ears.

- Use additional caution in children, older people and people with impaired hearing.
Contraindications and cautions

Monitoring
- Assess persistent local irritation or contact dermatitis.

Formulation and product differences
- The selected product is a smooth white nasal cream.
- It contains cetostearyl alcohol, which can cause local contact dermatitis.
- The current selected formulation's excipient list does not include arachis oil.
