Can I apply a medicated patch to the soles of my feet?

Generally speaking, the sole of the foot refers to the plantar surface. Whether or not the sole of the foot can be treated with medicated plasters mainly depends on individual circumstances. If there is inflammation or pain in the sole, it generally is acceptable to use medicated plasters; however, if the skin on the sole is broken, it is not recommended to apply such plasters. Detailed explanations are as follows:

Medicated plasters may be used when experiencing localized pain, inflammation, or injuries on the sole. For example, plantar fasciitis is a type of aseptic inflammation caused by repeated micro-injuries to the plantar fascia. Using plasters containing anti-inflammatory and analgesic ingredients can allow the medication to penetrate the skin and act on the inflamed area, reducing the inflammatory response and relieving pain.

However, if the skin on the sole is damaged—for example, due to cuts, abrasions, or ulcers—it is not advisable to use medicated plasters. This is because the plaster covers the wound, blocking air circulation and creating favorable conditions for bacterial growth, which may lead to wound infection. Moreover, some medicinal ingredients in plasters may irritate damaged skin, causing pain or allergic reactions.

When using medicated plasters regularly, attention should be paid to the duration of application and skin breathability, avoiding prolonged occlusion that could lead to infection. Additionally, maintaining clean and dry feet is important, and wearing non-breathable shoes and socks for extended periods should be avoided to prevent worsening of skin problems due to a moist environment.
