What should you know about care magnesium sulphate paste?

The paste is applied to the skin rather than swallowed. People may encounter it in advice about a small, inflamed area, but the right treatment depends on what the skin problem actually is. A lump, boil, wound or rash may need a clinician to examine it, especially if the cause is uncertain.

Do not assume that a paste will treat an infection beneath the skin. It cannot replace drainage, prescription treatment or assessment when those are needed. Keep the product away from the eyes, mouth and other sensitive areas, and check the package directions for the intended use.

Wash your hands before and after application. Clean and gently dry the area if the instructions advise this, then apply only the stated amount to intact skin and cover it only when the product directions say to do so. Avoid squeezing, piercing or repeatedly rubbing a painful lump.

Stop using it if burning, swelling, blistering or a spreading rash develops. Do not share the container, use an old or contaminated dressing, or apply it to a large area without professional advice. If you are pregnant, breastfeeding, caring for a child, or taking other treatment, ask a pharmacist or clinician whether this product is suitable for you.

Arrange prompt medical advice for increasing redness, warmth, swelling or pain, pus, fever, red streaks, or a wound that is not settling. Seek urgent help if you feel very unwell, the swelling is near the eye, or you develop trouble breathing or facial swelling after applying the product.

A clinician can check whether the problem is an abscess, cellulitis, an allergic reaction or another condition needing different care. Do not delay assessment because the paste seems to reduce surface discomfort.

Ask: What is the skin problem, and is this paste appropriate for it? How often should I apply it, and for how long? Should the area be covered? What changes mean I should stop? Could another medicine, pregnancy, breastfeeding or an allergy affect its use?
