Indication of Gelclair

Gelclair is a product used to provide pain relief to patients with conditions involving damage to the mucous membranes of the mouth. It can also be used to relieve pain associated with wounds or lesions in the mouth, for example following dental surgery.

Action description of Gelclair

Gelclair is classified as a medical device rather than a medication. This is because it has no pharmacologically active ingredient (i.e. it does not contain any drug or medication). The device works by adhering to the mucous membranes of the mouth and forming a physical barrier around them. In particular, it covers nerve endings that have become exposed as a result of damage to the mucosa. The barrier provides physical protection and reduces irritation to the mucous membranes.

Dose advice of Gelclair

Dose information

Gelclair is sold in 15 mL sachets. The recommended dose is one sachet, three times per day, one hour before each main meal. Some individuals may need to use Gelclair more often to relieve pain, and it is safe to do so.

At least one hour before using Gelclair, brush your teeth and/or use mouthwash, and apply any topical solutions (e.g. pain relief creams) you are using.

Do not eat for at least one hour after applying Gelclair.

To apply Gelclair, dilute the contents of the sachet with two tablespoons of water. Immediately after dilution, rinse the solution around in the mouth for one minute, so that it covers all the oral mucosa (e.g. tongue, gums, throat). The solution should then be gargled and spat out (although there are no side effects if the solution is swallowed accidentally).

For individuals who have difficulty rinsing and gargling the solution, or in situations when water is unavailable, the contents of the Gelclair sachet can be used undiluted. The undiluted solution should be applied directly to the mucous membranes of the mouth, and particularly visible oral lesions, using a syringe or cotton bud. This method may also be used when applying Gelclair for young children or for individuals with only a few, easily identifiable oral lesions.

Consult your healthcare professional if you have questions about using Gelclair.
