2.1. Active Ingredients
2.2. Quantitative Composition
Sterile, non-pyrogenic irrigating solution for administration to human beings.
Chlorhexidine Acetate BP is a disinfectant which is effective against a wide range of vegetative gram-positive and gram-negative bacteria.
Dosage and duration of administration are to be individualized and depend upon the indication for use, the patient's age, weight, clinical condition, and concomitant treatment, and on patient's clinical response to treatment (See Section 4.4 Chemical Burns in Neonates and Preoperative Skin Preparation).
Chlorhexidine Acetate BP 0.05% w/v for Irrigation is recommended for general topical use when antibacterial irrigation is indicated, including wound and burn irrigation.
Not for intravenous or oral route of administration or for use in body cavities (please see section 4.4).
In patients with a known hypersensitivity to the product or any of its components, especially in those with a history of possible chlorhexidine-related allergic reactions (see sections 4.4 and 4.8)."
Do not use in the eye, auditory canal (especially in perforated eardrums), or near meninges, brain or spinal cord (See Section 4.4 Special Warnings and Precautions for Use).
This solution is not to be taken orally.
This solution is not for intravenous administration. Accidental ingestion should be treated with a stomach lavage consisting of milk, egg white, gelatine or mild soap.
Idiosyncratic reactions to Chlorhexidine Acetate BP have been reported.
Chlorhexidine Acetate contains chlorhexidine, which is known to induce hypersensitivity, including generalised allergic reactions and anaphylactic shock, which can be fatal. The prevalence of chlorhexidine hypersensitivity is not known, but available literature suggests this is likely to be very rare. This product should not be administered to anyone with a potential history of an allergic reaction to a chlorhexidine-containing compound (see sections 4.3 and 4.8).
If any signs or symptoms of a suspected hypersensitivity reaction develop, immediately stop use. Appropriate therapeutic countermeasures must be instituted as clinically indicated.
Chemical Burns in Neonates and Pediatric Patients
The use of chlorhexidine solutions, both alcohol based and aqueous, for skin antisepsis prior to invasive procedures has been associated with skin reactions such as chemical burns in neonates. This risk appears to be higher in preterm infants, especially those born before 32 weeks of gestation and within the first 2 weeks of life.
Remove any soaked materials, drapes or gowns before proceeding with the intervention. Do not use excessive quantities and do not allow the solution to pool in skin folds or under the patient or drip on sheets or other material in direct contact with the patient. Where occlusive dressings are to be applied to areas previously exposed to chlorhexidine, care must be taken to ensure no excess product is present prior to application of the dressing.
Preoperative Skin Preparation
Caution should be exercised when chlorhexidine is used in preoperative skin preparations for face or head (See Section 4.3 Contraindications).
The activity of chlorhexidine is reduced or neutralized by an alkaline pH, the presence of organic matter, anionic detergents, and tannins.
Physicians should carefully consider the potential risks and benefit for each specific patient before prescribing chlorhexidine.
Chlorhexidine has been used in pregnant women and no harmful effects have been reported.
There are no adequate data to support the use of chlorhexidine in lactating women.
Chlorhexidine acetate has no influence on the ability to drive and use machines.
