Indications
Precipitated Sulphur (sulfur) is a fine yellow powder used in creams, ointments, lotions and soaps for skin conditions. It is used to treat scabies (an itchy infestation by tiny mites), acne, seborrhoeic dermatitis and dandruff, and some fungal skin infections such as pityriasis versicolor. It is often combined with Salicylic Acid in scalp and skin products.
How It Works
On the skin, sulphur is slowly changed into substances that kill scabies mites and some bacteria and fungi. It also has a keratolytic effect, which means it softens and loosens the top layer of dead skin and unblocks pores, helping to clear acne and scaling. It mildly dries oily skin.
Dosage and Administration
Use as directed on the label or by your doctor, as the method depends on the product strength and the condition. For scabies, sulphur ointment is usually applied to the whole body from the neck down at night for a few nights in a row, washing it off before each new application; all household members are usually treated at the same time. For acne or dandruff, apply a thin layer to the affected area once or twice a day, or use the shampoo or soap as directed. For external use only.
Interactions
- Other acne or peeling products, such as Benzoyl Peroxide, Tretinoin or Resorcinol: using them on the same skin can cause severe dryness and irritation.
- Topical mercury-containing products: should not be used with sulphur, as they can form an irritating compound and stain the skin.
Contraindications
Do not use if you are allergic to sulphur or any ingredient in the product. Avoid broken, raw or severely inflamed skin.
Side Effects
Common effects include dryness, mild redness, peeling, stinging and an unpleasant smell. Sulphur may stain clothes and bedding and can discolour silver jewellery. Allergic skin reactions are uncommon.
Stop using it and get urgent medical help if you develop swelling of the face or lips, difficulty breathing, or a severe, blistering or rapidly spreading rash.
Pregnancy and Lactation
Sulphur applied to the skin is generally considered one of the safer options for scabies in pregnancy and in breastfeeding mothers, but use it only on a doctor’s advice. Do not apply to the nipples before breastfeeding.
Precautions and Warnings
Keep it away from the eyes, mouth and inside the nose. For scabies, wash bedding, towels and clothing in hot water after treatment; itching can continue for a few weeks even after the mites have gone. Children and infants need a weaker strength as prescribed. See a doctor if the condition does not improve.
Overdose
Using too much on the skin may cause marked irritation; wash it off with soap and water. If swallowed, contact a doctor or poison centre for advice.
Therapeutic Class
Topical scabicide, keratolytic and antiseptic.
