The dosage information below outlines the instructions for the differing ailments and delivery methods. Whichever condition is being treated, it is imperative that the affected area is thoroughly cleaned prior to application.

Acne sufferers should use whichever delivery option that is most effective or preferable to them on an as-needed basis. If you choose to use the ointment, a strength of 0.5% is recommended. Scabies patients typically rely on sulfur ointment with a strength of 6% that is used for three consecutive nights. An ointment that is 5% to 10% in strength is typically used in the treatment of seborrheic dermatitis.

Side Effects:

Sulfur does not cause any medically dangerous side effects that require you to contact your doctor. However, if your symptoms do not improve or become worse it is always advisable to contact your doctor. Sulfur may cause dry skin at the point of application and the immediate surrounding area.

If you experience any side effects that do not dissipate after a few days or begin to worsen, it may be a sign of a more serious issue that could require additional medical attention.


Due to its topical nature, it is imperative that the area to be treated is thoroughly cleaned with both soap and water prior to application and be sure to completely dry the area before you apply the sulfur medication. If you are utilizing sulfur in either cream, lotion, or ointment form, apply a small amount to the affected area and gently rub into the skin. Do not pull on the skin or apply too much pressure. These instructions apply to the use of sulfur for the treatment of acne, seborrheic dermatitis, and other relevant skin disorders.

If you are using sulfur soap, the instructions are fairly straightforward: using warm water, create a strong lather from the soap and spread it all over the affected areas before rinsing completely. Following this cleanse, re-lather the affected areas of the body for a few minutes and gently rub the lather into the skin before toweling or tissuing off any excess lather. Do not rinse the affected areas where you gently rubbed in the soap to the skin.

Patients that are using sulfur for the treatment of seborrheic dermatitis are typically advised to use an ointment that is a 5% to 10% concentration and apply it one to two times each day.

Acne sufferers can use either the lotions, creams, and ointments or the sulfur soap to treat the condition. Sulfur is recommended to be used as needed for the treatment of this ailment. If ointment is the preferred method of delivery the 0.5% strength is advised.

For patients that are using sulfur to treat scabies, the instructions are different. Sulfur that is being used to treat this affliction is applied at bedtime. Before using this scabies medication it is imperative to fully wash the entire body with soap and water and then fully dry the skin. Apply the ointment from the neck down and cover the entire body and rub it in, but gently. It is important to keep the ointment on the skin for a full 24-hour period.

Always wash your entire body after the 24-period of having the ointment on the skin. If you are going to reapply the sulfur medication for another treatment, be sure to fully wash the entire body with both soap and water and dry your skin thoroughly prior to application. The typical strength of sulfur for the treatment of scabies is the 6% ointment, with the recommended dose of treatment for 3 consecutive nights.

These lotions and ointments are available in different strengths with the age of the patient, the severity of the condition, and the type of affliction that is being treated all contributing to the determination of which dosage will be most effective.

If the treatment does not help to lessen the symptoms after a few treatments, or if the symptoms worsen, it is always advisable to contact your physician or pharmacist for advice as there may be another medication available that will be more effective in treating your condition.

Dosage information is the same for both adults and children that are using sulfur, but it is always advisable to confer with your pediatrician before administering a new medication to your child.
