The medication should only be used to treat such a condition if the dentist prescribes it. It is also important to note that it should not be shared with others, even if they have the same condition as you.
Chlorhexidine gluconate may cause a severe yet rare allergic reaction that could be life-threatening. Immediately seek medical help if you are experiencing wheezing, skin rash, hives, cold sweats, difficulty breathing, swelling of the throat, tongue, lips, and face, as well as light-headedness.
The medication should never be given to a teenager or child without proper advice from the doctor as it can cause chemical burns or severe irritation.
Prior to taking the medicine
The medication should not be used by those who may have allergic reactions to chlorhexidine gluconate. For those with periodontal disease, unique treatments may be required while taking chlorhexidine gluconate.
At the same time, teenagers or children should not be given this medication without advice from the doctor. This is because it can trigger chemical burns and severe irritation in young children. The medication is not approved to be used by people who are below 18 years old.
It is still unknown if the medication can cause harm to unborn babies. Speak with your doctor if you are pregnant or have plans to be pregnant soon. There are no details yet whether the medication can pass into breast milk or if it can affect a nursing baby. Inform your doctor if you happen to be breastfeeding.

Cardiac arrest, hypotension, circulatory collapse, and tachycardia happened as hypersensitivity responses.
Frequency (not reported): Anaphylactoid reactions, anaphylactic shock
Post-marketing reports: Hypersensitivity and anaphylaxis
Frequency (not reported): irritation to the conjunctiva. irreversible corneal damage
Eye exposure to chlorhexidine cleanser, especially during the preparation phase for a facial surgery has greatly resulted in eye pain, as well as edema of the epithelium, inflammation of the conjunctiva, keratitis, chronic corneal ulcers, corneal epithelial cell loss, and opacification. To correct permanent damage, corneal transplantation has been needed in some patients.
Allergic conjunctivitis is not often associated with the utilization of contact lens solutions that contain low-level concentrations of chlorhexidine as a type of preservative.
Hematuria happened after bladder irrigation.

Frequency (not reported): Allergy
Indication and dosage
Usual Adult Dosage for Gingivitis
Usual dosage: 15 mL or about 0.5 fluid ounces is swished into the mouth unadulterated for 30-seconds and then spit out 2-times a day
Overdose and Contraindication
Allergic reaction to chlorhexidine or any element of the formulation
Chlorhexidine showed some activity against gram-negative and gram-positive organisms, as well as facultative anaerobes, yeast, and aerobes. At the same time, it is considered to be both bactericidal and bacteriostatic, depending on the concentration. Some of the bactericidal effects of chlorhexidine resulted from the attachment of the cationic molecule to a negatively charged bacterial cell wall and extra-microbial complexes. When at low concentrations, such causes a modification of bacterial cell osmotic equilibrium, as well as leakage of phosphorous and potassium were resulting in bacteriostatic effects. On the other hand, at high concentrations, the cytoplasmic substances of the bacterial cell cause and lead to cell death.
