Corsodyl is a medicated mouthwash that serves to kill microorganisms in the mouth and promote the health of teeth and gums. Like any medication, it does have side effects that are experienced by some users.

What is Corsodyl mouthwash?

Corsodyl mouthwash is an over-the-counter antimicrobial mouthwash that features chlorhexidine digluconate as its active ingredient. The mouthwash effectively kills most common microorganisms in the mouth, including bacteria, viruses, spores and fungi. Corsodyl is also effective against the build-up of plaque on the teeth. To ensure proper effectiveness, 10ml of wash should be used for 60 seconds twice a day.

What is Corsodyl mouthwash?

Corsodyl mouthwash helps maintain the integrity of the mouth and promotes oral hygiene, prevents and treats gingivitis (a gum disease), aids in healthy healing after dental surgery, treats ulcers and sores within the mouth, manages thrush (a mouth and tongue yeast infection) and treats and minimises irritation from dentures and partials.


Some users of Corsodyl mouthwash might experience side effects, which are usually temporary and lessen in severity as the mouth becomes used to the mouthwash. A temporary taste disturbance, burning sensations, temporary brownish staining of the teeth and tongue, irritation of the skin and mucus membranes, salivary gland swelling and peeling of the skin inside the mouth may occur. If any of these side effects are excessively bothersome, try diluting the mouthwash to a 50/50 mixture with water.

Side effects

Don't swallow Corsodyl. Avoid getting the mouthwash in your eyes or ears; doing so can cause stinging. The ingredients in Corsodyl interact with some of the ingredients in regular toothpaste. To make sure that you obtain the maximum effectiveness from the mouthwash, brush your teeth at least 30 minutes prior to using the mouthwash. If you are using the mouthwash to clear up a case of ulcers or thrush, continue treatment for at least two days to assure that the microorganisms that caused the infections have been killed so the infection does not return.


If you are allergic to chlorhexidine, you should not use Corsodyl. Corsodyl is safe for use during pregnancy and breastfeeding so long as it is spit out after use. Although very rare, if you should experience difficulty breathing or swelling of the face or tongue, call 911 or head to your nearest A&E, as this signifies a possible life-threatening allergy to Corsodyl.
