It is widely used as an antiseptic for skin use, it is also found in mouthwashes, and it is also used in the composition of products such as toothpastes or even certain cosmetics: chlorhexidine is the subject of an implementation in custody of the National Agency for the Safety of Medicines and Health Products (ANSM).
In question ? A risk of serious immediate allergic reaction. “We observe a steady increase in the number of reports of serious allergic reactions associated with chlorhexidine”we can read in a press release published on November 30.
Chlorhexidine: the risk of allergic reaction is rare, but vigilance is required
The ANSM specifies that these reactions are rare, but recalls that many people are exposed to chlorhexidine, which increases the risk of allergic reactions. As a precaution, it is therefore recommended to consult the composition of the products you use to check if they contain this antiseptic.
She also recalls do not use it as a first disinfectant at homeand to favor washing with clear water and soap, which “is the action to be carried out as a priority to clean a superficial wound”.
Healthcare professionals are also called upon to offer their patients an alternative to chlorhexidine in the event of an allergy or suspected allergy to this product.
Allergic reaction to chlorhexidine: what are the signs to know and how to react?
Allergic reactions to chlorhexidine most often appear within an hour after using the product. Several symptoms can then appear:
- a rash with redness and itching;
- swelling of the face, lips, tongue or throat;
- wheezing or difficulty breathing;
- a feeling of weakness and dizziness;
- a metallic taste in the mouth;
- fainting;
- or even anaphylactic shock.
What should you do if you have these symptoms? The first reflex is obviously to stop all use of chlorhexidine and call 15. Furthermore, the ANSM recommends that people who have already experienced an allergic reaction to chlorhexidine notify their nurse, pharmacist, doctor, surgeon or dentist, but also mention this allergy in their Health Space.
