Quadrajel Gel is used to treat gum and mouth ulcers. Mouth ulcers are painful and small lesions in the mouth or base of gums. It can make eating, drinking, and talking difficult and uncomfortable.

Quadrajel Gel is a combination medication containing Metronidazole (an antibiotic), Lidocaine (local anaesthetic), and Chlorhexidine (an antiseptic). Quadrajel Gel is primarily used to treat mouth ulcers. Lidocaine helps treat mouth ulcers by forming a protective layer on the ulcer, blocking the transmission of pain signals to the brain, and decreasing the sensation of pain. Chlorhexidine is an antiseptic and disinfectant which effectively cleans out the ulcer surface to prevent infection, and metronidazole, being bactericidal in nature, kills the bacteria by damaging its DNA and preventing these bacteria's growth spread, hence relieving the symptoms. As a result, good oral hygiene is maintained.

Your doctor will decide the dose depending on the type of infection that is being treated. The most common side effects of Quadrajel Gel are metallic taste, bitter taste, burning, transient redness, irritation, dryness, and staining of teeth. If these side effects are persistent and bothersome, please see your doctor. 

Please inform your doctor before using Quadrajel Gel if you are pregnant or breastfeeding.

Maintain good oral hygiene and brush at least 2 times a day to avoid any oral infection and its spread. Do not rinse the mouth or drink or eat anything for 30 minutes after applying Quadrajel Gel.
