Introduction
Boric acid becomes ineffective about one month after being opened. All products and medications have an expiration date, and should not be used beyond that date. The typical shelf life of boric acid is two to three years, but once opened, its shelf life is shortened significantly. It is generally recommended to use boric acid within one month after opening to avoid ineffectiveness. Boric acid is primarily used for disinfection, preservation, and sterilization.

In clinical practice, it is commonly used to treat small-area acute eczema, acute dermatitis, pressure ulcers, and similar conditions. Additionally, doctors frequently use boric acid to treat eczema accompanied by local erosion and exudation. Applying boric acid to affected areas can help reduce inflammation and swelling.
It is important to note that if obvious sensations such as burning, itching, or pain occur at the application site after using the medication, the area should be immediately washed thoroughly with clean water. If discomfort or pain persists after washing, medical attention should be sought promptly to prevent skin irritation or damage.
