Indications
Precipitated Sulphur is a fine yellow sulphur powder used in creams, ointments, lotions and soaps for the skin and scalp. It is used for acne, seborrhoeic dermatitis and dandruff, and in some combination products for psoriasis. Sulphur ointment is also an older but still useful treatment for scabies, especially in babies and pregnant women.
How It Works
On the skin, sulphur is slowly changed into substances that soften and loosen the outer layer of dead skin cells (a keratolytic effect), helping to clear blocked pores and scaling. It also has mild antibacterial and antifungal actions and is toxic to the scabies mite.
Dosage and Administration
For external use only. Apply a thin layer to the affected skin as directed on the label or by a doctor, usually once or twice a day for acne and scalp conditions. For scabies, the ointment is applied to the whole body from the neck down on several nights in a row as instructed. Wash hands after use unless the hands are being treated.
Interactions
- Using it at the same time as other drying or peeling products (such as Benzoyl Peroxide, Salicylic Acid, Retinoids or alcohol-based products) can cause marked irritation.
- Do not use with topical mercury-containing products, as a black, irritating compound may form.
Contraindications
- Allergy to sulphur or any ingredient.
- Broken, raw or severely inflamed skin.
Side Effects
It may cause dryness, redness, peeling, itching or a burning feeling. It has a distinct smell and can stain clothes. Allergic skin reactions are uncommon.
Get urgent medical help if there is a severe rash, blistering, swelling of the face or difficulty breathing, or if the product is swallowed in a large amount.
Pregnancy and Lactation
Topical sulphur is very little absorbed and is considered one of the safer choices in pregnancy and breastfeeding when used as directed. Do not apply to the breast or nipple area before feeding.
Precautions and Warnings
- Avoid contact with the eyes, mouth and other mucous membranes.
- Start with less frequent use if the skin is sensitive.
- In babies and young children use only on medical advice.
- See a doctor if there is no improvement or the condition worsens.
Overdose
Too much on the skin causes irritation and peeling; wash it off and stop use for a while. If swallowed, it may cause stomach upset or diarrhoea; seek medical advice.
