Sulfur Drug Interactions, Uses, Effectiveness, Safety & More

Medically reviewed by ·Updated July 2026
What is this page for?

First and foremost: how Sulfur interacts with medications. The heart of this page is the interaction list — every drug Sulfur is known to interact with, and how serious each one is.

But these pages have grown well beyond that into a full monograph — what Sulfur is, what people use it for and how strong the evidence is, its safety and side effects, and answers to the questions we’re asked most — written and reviewed by the clinical staff at HelloPharmacist. It’s educational information from our licensed clinical databases, not medical advice, and we don’t sell or endorse products. Our editorial policy

What Severity, Likelihood & Evidence Mean

Severity — How Serious It Can Be

  • Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
  • Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
  • Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
  • No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

  • Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
  • Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
  • Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Where This Data Comes From

  • Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.

Sulfur: Uses, Safety & Side Effects

Medically reviewed by · Reviewed July 2026 ·
The bottom line

Sulfur is a mineral used mainly in topical skin products for acne, rosacea, dandruff, and certain skin infections, and has a long history in dermatology. Topical sulfur is generally well tolerated but can be drying and smelly; oral sulfur supplements like MSM are taken for joint pain, though the evidence is limited. Talk with your pharmacist or doctor before starting any sulfur product.

Overview

Sulfur is a naturally occurring chemical element and mineral found in the earth. It has been used in medicine and skin care for centuries. In its yellow, powdered form, elemental sulfur is added to many creams, ointments, lotions, soaps, and shampoos.

Sulfur is also part of larger compounds. One popular dietary supplement, MSM (methylsulfonylmethane), is an organic sulfur compound taken by mouth. Sulfur is also a building block of certain amino acids and proteins in the body.

Today, the most common use of sulfur is on the skin. People use it for acne, rosacea, dandruff, and some skin infections. Oral sulfur supplements are mainly used for joint and muscle discomfort.

How it works

Topical sulfur is thought to have keratolytic effects, meaning it helps soften and shed the top layer of skin. This may help unclog pores and reduce flaking. Sulfur also appears to have mild antibacterial and antifungal properties, which may explain its use in acne, dandruff, and certain skin infections.

For scabies, sulfur is believed to be toxic to the mites and their eggs when applied to the skin.

Sulfur is also a natural part of some amino acids and proteins in the body. Supporters of MSM suggest it provides sulfur the body can use, and some lab and animal research points to possible anti-inflammatory effects. Much of this mechanism research is preliminary and does not prove a clear benefit in people.

Possibly Effective Dandruff
Rating & evidence shown verbatim from Natural Medicines

Sulfur is an FDA-permitted ingredient of over-the-counter (OTC) topical products to treat dandruff. However, efficacy data from clinical trials is limited. In a study of 48 adults using shampoos containing sulfur 2%, salicylic acid 2%, or both ingredients twice weekly for 5 weeks, reductions in scaling and the number of desquamating cells per square centimeter were greater with any of the active treatments compared with the shampoo base alone. However, the combination of both ingredients produced significantly greater and earlier reductions than either active ingredient alone.

Sources Ref 88107 Ref 88108
Possibly Effective Scabies
Rating & evidence shown verbatim from Natural Medicines

Applying topical preparations of 5% to 20% precipitated sulfur in petrolatum appears to be effective for the treatment of scabies in some patients. Response occurs in 24% to 97% of patients, but is unpleasant due to the smell. Sulfur preparations are applied overnight (10-12 hours) for between 3 and 6 nights, with reduced efficacy when used for only 24 hours. Concentrations should be limited to between 2% and 6% for infants, children, adolescents, and pregnant women.

Also studied for 6 conditions — evidence insufficient to rate
Insufficient Reliable Evidence To Rate Acne
Rating & evidence shown verbatim from Natural Medicines

Sulfur in concentrations of 3% to 10% is an FDA-permitted ingredient in over-the-counter (OTC) topical products to treat acne. However, efficacy data is mainly anecdotal. Creams and ointments containing 1% to 10% sulfur have been used to treat acne for many decades, but sulfur is now generally found in combination with benzoyl peroxide, salicylic acid, or sodium sulfacetamide.

Insufficient Reliable Evidence To Rate Allergic rhinitis (hay fever)
Rating & evidence shown verbatim from Natural Medicines

A preliminary clinical study suggests that using a homeopathic nasal spray containing sulfur, luffa, Galphimia glauca, and histamine for 42 days has similar efficacy to cromolyn sodium nasal spray for relief of symptoms of allergic rhinitis.

Insufficient Reliable Evidence To Rate Chronic obstructive pulmonary disease (COPD)
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research shows that inhalation of aerosolized sulfurous water (Acqua Breta, Terme di Riolo) 5 mL once daily for 12 days does not improve lung function when compared with baseline in patients with COPD.

Sources Ref 98206
Insufficient Reliable Evidence To Rate Common cold
Rating & evidence shown verbatim from Natural Medicines

A preliminary clinical study suggests that taking a homeopathic product containing sulfur and German ipecac (Engystol, Heel GmbH) orally for up to 2 weeks during a cold provides similar symptomatic relief to conventional over-the-counter remedies such as antihistamines, antitussives, and NSAIDs.

Sources Ref 27849
Insufficient Reliable Evidence To Rate Hyperlipidemia
Rating & evidence shown verbatim from Natural Medicines

A preliminary clinical study suggests that drinking 50 mL of water from a sulfurous spring three times daily for 4 weeks reduces total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglyceride levels, and decreases platelet aggregability. However, the study has methodological problems, including the lack of a control group, and does not address the effects of sulfur alone.

Sources Ref 91101
Insufficient Reliable Evidence To Rate Rosacea
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research shows that applying sulfur 10% in an emollient base (Diprobase, Merck Sharp and Dohme) once daily for 4 weeks is as effective as oral tetracycline (300 mg twice daily for 1 week, then 150 mg twice daily for 3 weeks) for reducing rosacea papules and pustules. Using a combination of sulfur 5% and sodium sulfacetamide 10% in a topical emollient foam (Clarifoam EF, Onset Dermatologics) twice daily also seems to reduce the severity of rosacea. Other clinical research shows that using this same product for 8 weeks reduces inflammatory lesions by an additional 42% and erythema by an additional 52% when compared with placebo. In another study, using foam containing sulfur 5% and sodium sulfacetamide 10% for 8 weeks reduced papules, pustules, and overall severity of rosacea more than topical metronidazole 0.75% gel.

Safety & precautions

Topical sulfur is generally considered safe and well tolerated when used as directed. The most common problem is skin irritation, dryness, or a noticeable odor. People with sensitive skin should test a small area first.

Oral sulfur supplements like MSM are less thoroughly studied. People with kidney problems, or those who take many medications, should be especially careful and check with a healthcare provider before use.

Pregnancy: Topical sulfur is sometimes considered a lower-risk option for certain skin conditions, but you should still talk with your doctor before using it. Avoid unproven oral supplements during pregnancy.

Breastfeeding: There is limited information. Use only with guidance from your healthcare provider, and avoid applying sulfur products to the breast or nipple area where a baby could ingest them.

As with any supplement or skin product, talk to your pharmacist or doctor, especially if you have existing health conditions or take other medicines.

Side effects

Common side effects of topical sulfur include:

  • Dryness, redness, or peeling of the skin
  • Itching or mild burning
  • An unpleasant rotten-egg or sulfur smell
  • Staining of clothing or skin (with some products)

Oral sulfur supplements such as MSM may cause mild stomach upset, bloating, diarrhea, or headache in some people.

Serious reactions are uncommon. Stop use and seek medical care if you develop signs of an allergic reaction, such as a widespread rash, swelling, or trouble breathing.

Reports by condition
Diabetes Renal

There is one case report of metabolic acidosis occurring in a 57-year-old woman who had consumed approximately 250 grams of flowers of sulfur, a form of sulfur prepared by sublimation, over a 6-day period. Underlying conditions, including diabetes and renal failure, may have contributed to the acidosis. Sulfur is converted to sulfide by colonic bacteria and then to sulfate in various tissues, generating hydrogen ions which can lead to acidosis when clearance mechanisms are overwhelmed.

  1. Blum, J. E. and Coe, F. L. Metabolic acidosis after sulfur ingestion. N Engl J Med 1977;297(16):869-70.
Diarrhea Gastrointestinal

Orally, sulfur is converted to sulfide in the gastrointestinal tract, causing intestinal irritation which can lead to diarrhea.

  1. Blum, J. E. and Coe, F. L. Metabolic acidosis after sulfur ingestion. N Engl J Med 1977;297(16):869-70.
Pruritus Dermatologic

Topically, application of sulfur preparations can cause dryness, leading to local irritation and pruritus in up to 28% of patients.

Dosing

There is no single standardized dose for sulfur, and the right amount depends on the product and how it is used. Topical products contain different concentrations of sulfur, so always follow the directions on the label.

For oral supplements like MSM, there is no firmly established dose. Follow the manufacturer's instructions and do not exceed the recommended amount.

Because products vary so much, it is best to check with your pharmacist or doctor before starting, especially if you are pregnant, breastfeeding, have a medical condition, or take other medicines.

Sulfur: Common Questions

What is Sulfur used for, and does it work?
People use Sulfur for many reasons, but the evidence varies by use. According to the Natural Medicines database, there is at least some clinical evidence supporting Sulfur for Dandruff and Scabies. For most other uses it has been studied for, the evidence is currently insufficient to rate. See the graded list on this page, and always confirm with your pharmacist or doctor.
Does Sulfur interact with prescription medications?
We do not currently list any known drug interactions for Sulfur. This does not guarantee that none exist, so always confirm with your pharmacist before combining it with your medications.
How are Sulfur interactions rated?
Each interaction is graded major, moderate, or minor based on how clinically significant it is and the strength of the evidence behind it. Major interactions are the most serious and are best avoided, or used only under close professional supervision.
Is it safe to take Sulfur with my medications?
It depends on the specific medication. Some combinations are fine, while others call for monitoring, timing changes, or should be avoided. Check your exact drug above and confirm with your pharmacist or doctor before starting, stopping, or changing anything.
Where does this Sulfur interaction information come from?
Our interaction data is built on the Natural Medicines database — an evidence-graded reference for vitamins, herbs, and supplements — and is reviewed by licensed HelloPharmacist pharmacists, who may add clinical context.
What is Sulfur used for?
Sulfur is most often used in topical skin products for acne, rosacea, dandruff, and certain skin infections like scabies. Oral Sulfur supplements such as MSM are sometimes used for joint pain.
Is topical Sulfur safe to use?
For most people, topical Sulfur is well tolerated when used as directed. The main downsides are skin dryness, irritation, and a noticeable Sulfur smell.
Why do Sulfur products smell bad?
Sulfur naturally has a rotten-egg odor, so many Sulfur creams, soaps, and ointments carry that smell. The odor usually fades after the product is rinsed off or absorbed.
Can I use Sulfur products while pregnant?
Topical Sulfur is sometimes considered a lower-risk option for skin problems, but you should still check with your doctor first and avoid unproven oral supplements during pregnancy.
