Benzonac Gel is used for treatment of Mouth ulcers.
Medically reviewed by Dr. Balaji Krishnan, MBBS · Updated September 2026
Benzonac Gel contains Diclofenac (3% w/w) + Benzocaine (20% w/w). It belongs to the Non-steroidal anti-inflammatory drug and Antiseptic and disinfectant class of medicines.
Treatment of Mouth ulcers
Benzonac Gel is a combination of two medicines: Diclofenac and Benzocaine. Diclofenac is a non-steroidal anti-inflammatory drug (NSAID). It works by suppressing the production of chemical messengers (prostaglandins) that cause inflammation (redness and swelling) and pain. Benzocaine is a local anesthetic which blocks pain signals from the nerves to brain thereby decreasing the sensation of pain.
Check the label for directions before use. Gently apply the gel to the affected area inside your mouth. Refrain from eating or drinking immediately after applying the gel.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
If you miss a dose of Benzonac Gel, skip it and continue with your normal schedule. Do not double the dose.
An overdose of this medicine can cause stomach bleeding, kidney failure, drowsiness and fits. It is unlikely from skin use, but swallowing an antiseptic is dangerous and needs immediate medical attention. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.
Most side effects of Benzonac are mild and settle as the body adjusts. Reported side effects include:
Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

Take it with or just after food, and for the shortest time that works. Stop and seek urgent care for black or tarry stools, vomiting blood, or severe stomach pain — this group can cause bleeding from the stomach. Long or high-dose use raises the risk of heart attack, stroke and kidney injury, particularly in older people and those already at risk. Avoid if you are dehydrated or have an illness with vomiting or loose motions — the kidneys are vulnerable then. Must be avoided in the last three months of pregnancy. For external use only. Keep away from the eyes and the inside of the mouth and nose unless the product is made for that purpose. Do not use a strong antiseptic repeatedly on an open wound — clean running water and soap around the edges are usually better, and harsh antiseptics slow healing. See a doctor for a deep or dirty wound, an animal bite, a wound that will not stop bleeding, or one that becomes red, swollen, warm or discharges. Check that your tetanus cover is current after any dirty or penetrating wound.
Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Not for people with an active stomach ulcer, severe kidney or heart failure, or asthma triggered by aspirin or anti-inflammatory painkillers. Not in the third trimester of pregnancy. Not for use on large burns or deep wounds without medical advice.
Combining with a blood thinner or aspirin sharply raises the bleeding risk. Reduces the effect of blood pressure medicines and water tablets, and together with them can harm the kidneys. Never take two anti-inflammatory painkillers at the same time. No significant interactions are expected.
Store below 30°C, away from direct sunlight. Close the cap tightly after each use. Keep out of the reach of children.
Benzonac Gel is used to treat painful mouth ulcers. Avoid eating and drinking immediately after applying Benzonac Gel. Avoid putting dentures or braces back in the mouth for half an hour after applying the gel in your mouth. Use a soft toothbrush after consulting your dentist. Avoid spicy foods, acidic fruit drinks, and very salty foods (such as crisps) which can make the pain and sting worse. Do not smoke while using Benzonac Gel as it might cause some side effects. Consult your doctor if your pain does not improve after using this medication for 7-14 days, or if your symptoms get worse.
