Introduction
Medical underpads should not be used as sanitary napkins. The intended use and functional design of these two products are entirely different. Using medical underpads as a substitute for sanitary napkins can impair comfort and may increase the risk of skin irritation and infection. If symptoms such as skin redness, swelling, itching, or abnormal discharge occur after misuse, prompt medical attention is recommended. Sanitary napkins are specifically designed for menstrual blood absorption, featuring quick-absorption layers, fluid distribution layers, and breathable back sheets.

Using medical underpads in place of sanitary napkins can compromise comfort and increase the risk of skin irritation and infection.

In terms of functional design, sanitary napkins are specifically engineered for menstrual blood absorption, featuring quick-absorption layers, fluid distribution layers, and breathable back sheets that rapidly absorb menstrual flow and maintain dryness. Many also contain antibacterial components to reduce odor and the risk of infection. In contrast, medical underpads are primarily designed to prevent leakage and protect wounds, with absorption speed and breathability insufficient for the continuous demands of menstrual flow.

Regarding suitability for usage scenarios, women during menstruation have sensitive intimate skin requiring prolonged contact with hygiene products. Sanitary napkins are specially designed in size, fit, and breathability to meet these needs. Medical underpads, however, are typically one-size-fits-all, made of thicker materials with poorer breathability. Prolonged use can lead to a moist, stuffy environment, increasing the likelihood of skin irritation or infection.

When selecting hygiene products, it's important to distinguish based on purpose: opt for sanitary napkins suited to your menstrual flow during menstruation, and choose medical underpads for postoperative recovery or bedridden care. Always change products frequently, keep the intimate area clean and dry, and avoid compromising health through incorrect product use.
