Diclofenac+Capsaicin+Mephenesin+Camphor+Menthol is used for pain relief.

Diclofenac + Capsaicin + Mephenesin + Camphor + Menthol is a combination of five medicines. Diclofenac is a non-steroidal anti-inflammatory drugs (NSAID). It works by blocking the release of certain chemical messengers that cause pain and inflammation (redness and swelling). Capsaicin desensitizes the nerve endings which alleviates the pain, whereas rubefacients increase the blood flow of the affected area to give a warm and soothing feeling. Mephenesin is a muscle relaxant. It works on the centers in the brain and spinal cord to relieve muscle stiffness or spasm without reduction in strength. This improves the pain and movement of muscles. Camphor belongs to the class of medicines called rubefacients/antitussives. When applied to the skin, it increases blood flow and local temperature of the affected area which suppresses and temporarily relieves pain sensations. Menthol is an organic compound, extracted from peppermint oil. It activates the cold sensing chemical messenger, which gives a cooling effect.

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them
