Introduction
If iodine tincture is applied without subsequent deiodination, and only a small amount is used, it may cause no harm if promptly rinsed off with clean water upon discovery; generally, this will not damage the skin. However, if a large amount is used and not immediately washed off with water, problems may occur. The high concentration of iodine in the tincture may irritate the skin and mucous membranes, causing discomfort.
Under normal circumstances, if iodine tincture is applied without subsequent deiodination, there is generally no problem when the amount used is small. However, adverse effects may occur if a large amount is used. The specific analysis is as follows:
1. No problem
Iodine tincture can be used for skin disinfection and helps prevent skin infections. It is primarily composed of iodine and potassium iodide dissolved in an alcohol solution, containing a relatively high concentration of iodine. To reduce skin irritation, it is recommended to remove residual iodine with alcohol after application. If only a small amount of iodine tincture was used and not deiodized, promptly washing it off with clean water upon discovery typically prevents skin damage, and no significant local discomfort will occur.
2. Potential problems
If a large amount is used and not immediately rinsed off with water, complications may arise. Due to the high iodine concentration in the tincture, it may irritate the skin or mucous membranes, leading to symptoms such as local peeling, blistering, burning, or pain. Individuals with sensitive skin may also develop allergic reactions such as itching or rashes.
If any abnormal skin reactions occur after use, it is important to immediately rinse the area thoroughly with clean water or normal saline to minimize further irritation. When necessary, it is advisable to seek medical attention at a hospital as soon as possible.
