What is the most commonly used firmness for compression stockings without a prescription?

The most commonly used firmness for compression stockings without a prescription is in the range of 15-20 mm/Hg. This level of compression is generally deemed safe and effective for the general population, especially for those seeking relief from minor swelling or discomfort due to conditions like varicose veins or mild edema.

This compression level offers sufficient support and helps promote blood circulation without causing adverse effects, which could be a concern at higher levels of compression. Stockings in this category are readily available over-the-counter and suitable for daily wear, making them accessible for individuals who do not require a tailored medical approach.

Higher levels of compression, such as 20-30 mm/Hg and above, often necessitate a prescription because they are usually recommended for more substantial medical conditions that require careful monitoring and assessment. The more intense compression levels can cause complications or discomfort if not correctly indicated for an individual's condition. Therefore, the 15-20 mm/Hg range strikes a balance between effectiveness for common issues and safety for general consumers.
