Hypersensitivity Reactions

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).

4.5 Interaction with other medicinal products and other forms of interaction

The activity of chlorhexidine is reduced or neutralized by an alkaline pH, the presence of organic matter, anionic detergents, and tannins.

4.6 Pregnancy and lactation

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.

4.7 Effects on ability to drive and use machines

Chlorhexidine acetate has no influence on the ability to drive and use machines.

4.8 Undesirable effects

Immune system disorders (frequency not known:

Hypersensitivity reactions including anaphylactic shock and anaphylactoid reactions (see sections 4.3 and 4,4) manifested by cardiac arrest, circulatory collapse, hypotension, bronchospasm, tachycardia, rash, erythema and urticaria

Skin and subcutaneous tissue disorders (frequency not known):

Allergic skin reactions such as dermatitis, pruritus, erythema, eczema, rash, urticaria, skin irritation, and blisters.

Other Adverse Reactions

The adverse events reported and/or observed with other chlorhexidine products include:

Fatal anaphylactic reactions

Chemical burns in neonates (See Section 4.4 Special Warnings and Precautions for Use)

Reporting of suspected adverse reactions
