How many hours is it best to keep the stiff neck plaster applied?

Generally speaking, there is no fixed rule about "how many hours is best to wear a neck strain patch." It is more appropriate to apply the patch for 4–8 hours per session. The exact duration should be adjusted based on the type of patch and individual skin tolerance, with the goal of relieving neck discomfort without causing skin damage. Detailed analysis is as follows:

If using a common topical patch, since the skin absorbs the medication relatively slowly, applying it for 6–8 hours per session is sufficient. Prolonged use may impair skin breathability and lead to discomfort such as redness or itching. Such patches are typically applied once daily for 3–5 consecutive days, during which stiffness and pain in the neck usually gradually improve.

If using a transdermal patch or one containing irritating ingredients, individuals with sensitive skin should limit application time to 4–6 hours and closely monitor the skin's reaction at the application site. These types of patches have stronger drug penetration, so even short-term application can be effective. Extending the duration unnecessarily may increase skin irritation and hinder recovery.

During application, keep the neck skin clean and dry, and avoid applying the patch on broken or damaged skin. Minimize strenuous neck movements; instead, gentle massage or warm compresses may help relieve muscle tension and support recovery of neck function. After removing the patch, promptly clean any residual medication from the skin to maintain proper breathability.
