Sulfur recalls
From the FDA Enforcement database. A recall covers specific lots — not the drug as a whole.
Sulfur and breastfeeding
From LactMed, the US National Library of Medicine’s Drugs and Lactation Database — quoted, not rewritten.
Full LactMed record for sulfur: levels in milk, effects in breastfed infants, and the drugs it would consider insteadSulfur 5% to 10% in a petrolatum base is safe for topical use in children, including infants under 2 months of age. This makes it a useful alternative to organic insecticides for treating scabies in nursing mothers; however, the petrolatum base makes undesirable for use on the breast.

What people report to the FDA about sulfur
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 1,044 reports naming sulfur, and the FDA flagged 62% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:
- drug hypersensitivity184 reports
- nausea56 reports
- headache54 reports
- dyspnoea53 reports
- erythema50 reports
- hypotension49 reports
- anaphylactic reaction47 reports
- dizziness44 reports
Read these as a signal, not a rate. A report does not mean sulfur caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label section above.

Frequently asked questions
Can you take sulfur with other medicines?
It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run sulfur against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.
What forms does sulfur come in?
Across the brands we track, sulfur is currently marketed as powder, per the FDA's National Drug Code Directory. Each form is dosed differently — follow the label for the exact product you were prescribed.
Is there a generic sulfur?
We do not currently list a generic-labelled sulfur product. That does not always mean none exists — it means none appears under a generic name in the FDA data we track. Ask your pharmacist.
Has sulfur been recalled?
The FDA's Enforcement database lists 2 recall records whose product description mentions sulfur. The most recent: Kit for the Preparation of Technetium Tc 99m Sulfur Colloid Injection (Nov 22, 2024). A recall applies to specific lots, not to the drug as a whole — check the record for the affected lot numbers.
