How Long Does Magnesium Sulphate Paste Take to Work on a Splinter?
Splinters can be uncomfortable and challenging to remove, especially if they are embedded deeply in the skin. Magnesium sulphate paste is a popular remedy known for its ability to draw out splinters safely and effectively. This article explores how long it takes for magnesium sulphate paste to work on a splinter, its benefits, and how to use it correctly.
What Is Magnesium Sulphate Paste?
Magnesium sulphate paste, often referred to as drawing paste, is a medical preparation designed to draw out foreign objects, such as splinters, from the skin. It works by creating a hypertonic environment that encourages the movement of trapped particles toward the surface, facilitating easy removal.
How Does Magnesium Sulphate Paste Work on Splinters?
- Drawing Action: The paste applies osmotic pressure to the skin, softening the area around the splinter and encouraging it to rise to the surface.
- Anti-inflammatory Properties: It helps reduce swelling and irritation around the affected area, making the splinter easier to extract.
How Long Does It Take to Work?
The time it takes for magnesium sulphate paste to work depends on several factors, such as the depth and size of the splinter.
- Shallow Splinters: These may be drawn out within a few hours, often requiring as little as 3–4 hours for visible results.
- Deeper Splinters: For larger or deeper splinters, you may need to leave the paste on for 12–24 hours, reapplying as necessary.
How to Use Magnesium Sulphate Paste on a Splinter
- Clean the Area: Wash the affected area with soap and water to remove dirt and bacteria.
- Apply the Paste: Use a clean applicator to spread a thick layer of the paste directly onto the area where the splinter is embedded.
- Cover with a Dressing: Place a plaster or sterile bandage over the paste to keep it in place.
- Wait: Leave the paste on for the recommended time based on the depth of the splinter.
- Remove and Inspect: After the set time, gently remove the dressing and check if the splinter has risen to the surface. If needed, repeat the process.
