What should you know about magnesium sulphate glycerine paste?

This paste combines magnesium sulphate with glycerine in a product intended for external use. It is not the same as magnesium sulphate injected into a vein for pre eclampsia or fetal neuroprotection. The intended site, amount, dressing, and length of use depend on the skin problem and the product instructions. A pharmacist can confirm whether the formulation is suitable for your age, pregnancy status, allergies, and other treatments.

Do not assume that a product labelled magnesium sulphate is interchangeable with another form. Ingredients, strength, sterility, and route of use can differ. Applying it to broken skin may sting or irritate, and covering an area tightly can alter moisture and absorption. Follow the supplied directions rather than making a stronger mixture yourself.

Wash your hands before and after application, clean the area as instructed, and use only the amount advised. Keep the paste away from eyes, mouth, and other mucous membranes. Do not share the container, and keep it out of children’s reach. Stop and ask a pharmacist or clinician if a rash, burning, swelling, or worsening pain appears. Tell the prescriber about diabetes, circulation problems, immune problems, pregnancy, and medicines applied to the same area.

Seek prompt medical care for rapidly spreading redness, increasing warmth or swelling, severe pain, pus, red streaks, fever, facial swelling, or trouble breathing. A wound that is deep, caused by a bite, contains a foreign object, or does not improve as expected may need a different treatment. Do not use the paste to delay assessment of a serious infection or injury.

Ask what condition the paste is meant to treat, where it should be applied, whether it needs a dressing, how long to use it, and what to do if the area becomes more painful or irritated.
