counterpain

Counterpain is a brand of topical analgesic used to relieve temporary minor aches and pains in muscles and joints. It is categorized as a counterirritant, meaning it produces a local sensation on the skin—such as cooling, warming, or tingling—that helps distract from deeper pain.

Most Counterpain formulations contain menthol and methyl salicylate, with some versions including camphor. The exact ingredients and concentrations can vary by country and product line. The active ingredients are intended for external use only and are not a cure for injury.

The proposed mechanism involves stimulation of cutaneous sensory nerves, creating a transient sensation that can mask or reduce the perception of pain in the treated area. The effect is topical and short-term, and the product should be used as directed on the label.

Common uses include temporary relief from muscle strains, sprains, arthritis-related discomfort, backaches, and general overexertion. Counterpain is applied to the affected area in a thin layer and usually repeated several times a day as needed, according to the product instructions.

Safety and handling: avoid applying to broken or irritated skin, mucous membranes, or near the eyes. Wash hands after use. Do not cover the treated area with tight bandages or apply heating devices unless specified. Keep away from flames or heat sources, as the product often contains volatile solvents. Do not use on children beyond label recommendations, and consult a clinician before using during pregnancy or breastfeeding. Possible adverse effects include skin irritation, rash, or allergic reactions.

Counterpain is available as an over-the-counter topical option in many regions and is intended for short-term relief of minor aches.
