Topical Painkiller (NSAID) with Cooling Agent
Last reviewed July 2026
Who is this for?
This is a topical gel that combines diclofenac (a painkiller and anti-inflammatory drug) with menthol (which gives a cooling sensation) to reduce pain and swelling when rubbed on the skin. It works by blocking the chemicals in your body that cause pain and inflammation right at the spot where you apply it.
Inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis and local inflammatory mediators; menthol provides additional analgesic effect through topical counter-irritation and activation of cold-sensitive TRPM8 receptors.

Since this gel is used as needed for pain, there is no strict dosing schedule. If you forget to apply it, simply apply it when you remember, but do not use extra gel to make up for a missed application.
Buy only from registered pharmacies, as products like PKN Diclofenac Sodium & Menthol Gel from roadside sellers may be expired or fake. Do not apply near your eyes, mouth, or on sensitive areas. This gel is for external use only: never swallow it or use it on large portions of your body at once.
Avoid using other pain-relief creams or gels on the same area at the same time, as this can cause skin irritation or increase side effects. If you are already taking oral painkillers like ibuprofen or diclofenac tablets, talk to your pharmacist before using this gel as it may increase the overall amount of painkiller in your body. Avoid applying the gel on areas where you have used traditional herbal balms or hot rubs.
