Product introduction
Benzonac Gel should be used strictly as advised by your doctor. Use it in the dose and duration as directed by your doctor. You should not use more quantity or more often than prescribed by your doctor. This will not make it work any faster rather increase the chance of side effects.
It is usually safe with little or no side effects. However, it may cause a burning or stinging sensation immediately after use. These are temporary and usually resolve with time. If they do not get better with time or worsen, you should let your doctor know. Your doctor may be able to suggest ways of preventing or reducing the side effects.
Before using the medicine, it is important to tell your doctor if you are using or have recently used any other medicines for the same condition or other diseases. To make sure the medicine is safe, pregnant and breastfeeding women should consult their doctor before using the medicine.

How Benzonac Dental Gel works
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.
