Taiwan FDA warns against misuse of topical pain relievers

Taiwan's Food and Drug Administration (TFDA) is reminding the public that improper use of topical pain relievers can lead to skin damage. The agency stresses the importance of safe application practices to effectively alleviate muscle soreness while reducing the risk of irritation and adverse reactions.

When applying pain relief creams or gels, users should first clean their hands and ensure the affected area is dry. Creams, with their higher oil content, are suitable for thicker skin areas, while gels offer a lighter feel and often contain cooling ingredients like menthol. For patches and sprays, users should clean and dry the skin before application. Patches come in oil-based and water-based varieties, with oil-based ones offering better adhesion and a choice of cooling or warming sensations, while water-based patches are gentler on the skin but may not stick as well. Sprays are convenient for hard-to-reach or large areas and are less likely to detach due to sweat or movement.

The TFDA strongly advises against applying these medications to wounds, broken skin, or areas with eczema or rashes. Users must strictly follow the product's instructions regarding application time and dosage. Continuous use beyond the recommended duration, typically not exceeding four to six hours per application, should be avoided to prevent skin discomfort or systemic side effects. The application area should also be limited to the affected site, and overuse, especially with sprays, should be prevented to avoid excessive absorption and potential adverse reactions.

Muscle soreness can stem from various factors, including poor posture, prolonged sitting or standing, and improper exercise habits. For mild discomfort, rest, hydration, and a balanced diet may suffice. However, for persistent pain, consulting a doctor or pharmacist is recommended, especially if you have known allergies to ingredients like non-steroidal anti-inflammatory drugs (NSAIDs) or salicylates, which are common in many topical pain relievers.
