Best over-the-counter options for scabies

A pyrethroid that "acts on the nerve cell membrane to disrupt the sodium channel current," paralyzing the mite. The FDA label directs you to "Thoroughly massage permethrin cream into the skin from the head to the soles of the feet" — in practice, adults treat from the jawline down to between the toes, while infants, children and elderly patients also get the scalp, hairline, temples and forehead. Leave it on 8 to 14 hours, then shower it off. "Usually 30 grams is sufficient for an average adult," so one 60 g tube treats one adult twice or two adults once. It is the same molecule as the OTC lice rinse at five times the concentration, in a cream base meant for whole-body use, with a whole-body FDA indication behind it.

The FDA label states: "Permethrin cream is indicated for the treatment of infestation with Sarcoptes scabiei (scabies)" and "ONE APPLICATION IS GENERALLY CURATIVE." It is marked "Rx Only" and "Each gram contains permethrin 50 mg (5%)." CDC's ectoparasitic treatment guideline lists the recommended regimen as "Permethrin 5% cream applied to all areas of the body from the neck down and washed off after 8–14 hours" or "Ivermectin 200 ug/kg body weight orally, repeated in 14 days," and notes "Topical permethrin and oral and topical ivermectin have similar efficacy for cure of scabies." The American Academy of Dermatology says plainly: "Medicine that treats scabies is only available with a doctor's prescription."

Caution: Prescription only — there is no legal OTC route to 5% permethrin in the US. Do not stop at the neck for everyone: the label states "Scabies rarely infests the scalp of adults, although the hairline, neck, temple, and forehead may be infested in infants and geriatric patients," and "Infants should be treated on the scalp, temple and forehead." CDC extends that to all children — "For children, apply the scabicide lotion or cream to their entire head, neck, and body" — so an elderly patient or a child treated neck-down can be left with live mites in the hairline. The label clears the cream for "pediatric patients two months of age and older"; safety under 2 months is not established, and CDC notes "Only permethrin or sulfur ointment may be used in infants." "Permethrin cream is contraindicated in patients with known hypersensitivity to any of its components, to any synthetic pyrethroid or pyrethrin." Burning and stinging occurred "in 10% of patients," and the label warns treatment "may temporarily exacerbate" pruritus, edema and erythema. Do not re-apply because you still itch: "Patients may experience persistent pruritus after treatment. This is rarely a sign of treatment failure and is not an indication for retreatment. Demonstrable living mites after 14 days indicate that retreatment is necessary."

Nothing reliable for scabies. This is the product people buy because the active ingredient name matches. Its Drug Facts panel lists, per fluid ounce, "Permethrin 280 mg (1%)" with the purpose "Lice treatment" and the single use "treats head lice." It is designed to sit on damp hair for exactly 10 minutes, not to be smeared over an adult's entire body overnight, and it has never been tested or approved at that concentration against a burrowing mite.

The Nix Drug Facts label reads: Active ingredient (in each fluid ounce) "Permethrin 280 mg (1%)," Purpose "Lice treatment," Use "treats head lice," and directs users to "leave Nix® on the hair for 10 minutes, but no longer." CDC states: "Scabicides require a doctor's prescription. No non-prescription products have been tested and approved to treat scabies," and the treatment page adds "Do not use over-the-counter (non-prescription) products to treat scabies."

Caution: Using it anyway wastes 1 to 2 weeks while the mites keep breeding and keep spreading to the people you live with, and every week of delay means more contacts to treat. The label's own limits: "Do not use on children under 2 months of age," "near the eyes," "inside the nose, ear, mouth, or vagina," or "on lice in eyebrows or eyelashes." It also warns to "Ask a doctor before use if you are allergic to ragweed. May cause breathing difficulty or an asthmatic episode." Stop use and see a doctor if "breathing difficulty occurs," "eye irritation occurs," or "skin or scalp irritation continues or infection occurs."

Blunts the inflammatory itch — it does not touch the mite. Its real value is the post-scabetic phase, the 2 to 4 weeks after the prescription scabicide when your skin is still reacting to dead mites and their debris. Apply to the itchiest patches "not more than 3 to 4 times daily." On the FDA OTC monograph its stated purpose is literally the single word "Anti-itch."

The OTC Drug Facts label: Purpose "Anti-itch"; Uses "temporarily relieves itching associated with minor skin irritations, inflammation, and rashes due to: eczema, insect bites, poison ivy, oak, or sumac, soaps, detergents, cosmetics, jewelry, seborrheic dermatitis, psoriasis." CDC explains why the itch outlasts the cure: "The itching from scabies is due to a hypersensitivity reaction (allergy) to mites and their feces; itching may continue for several weeks even if all the mites and eggs are killed." AAD lists "Steroid cream: To ease the redness, swelling, and itch" among the add-on treatments a dermatologist may prescribe alongside the scabicide.

Caution: Seven days is the label ceiling: stop use and ask a doctor if "condition worsens, symptoms persist for more than 7 days or clear up and occur again within a few days." Dosing is "adults and children 2 years of age and older: apply to affected area not more than 3 to 4 times daily"; "children under 2 years of age: do not use, ask doctor." Do not use "for the treatment of diaper rash" or "in the genital area if you have a vaginal discharge," and avoid contact with eyes. Because it suppresses the rash without killing anything, using hydrocortisone alone on undiagnosed scabies quiets the signs while the infestation keeps growing and keeps transmitting — it buys comfort, never a cure.

For adults under 65, a sedating antihistamine is used for the part of scabies that ruins people: itching that peaks at night and keeps you awake. Diphenhydramine 25 mg, 1 to 2 tablets every 4 to 6 hours, is the classic adult bedtime choice. Dermatologists use it as an adjunct alongside the scabicide, not instead of it. It is not a way to sedate a child — the Drug Facts panel forbids that outright — and it is the wrong drug for an older adult.

AAD lists among additional treatments for scabies: "Antihistamine: To control the itch and help you sleep." The OTC Drug Facts panel for diphenhydramine 25 mg gives dosing as "adults and children 12 years and over: 1 to 2 tablets," "take every 4 to 6 hours, or as directed by a doctor," "do not take more than 6 times in 24 hours," and warns "marked drowsiness may occur." The label's "Do not use" panel is unconditional: "Do not use to make a child sleepy." For the other end of the age range, the Medi-Cal Rx drug-use-review article states that "The 2023 American Geriatrics Society (AGS) Beers Criteria for Potentially Inappropriate Medication Use in Older Adults recommends that individuals 65 years or older avoid use of first-generation antihistamines, including oral diphenhydramine."

Caution: Two hard age boundaries, not one. The label's flat prohibition — "Do not use to make a child sleepy" — means the bedtime-sedation strategy on this page is never for children; a child's nighttime scabies itch belongs with the prescriber. Age bands below: "children under 6 years of age: do not use"; children 6 to under 12 get 1 tablet, and only for the labeled allergy indication. At the top end, adults 65 and older should skip it: "Diphenhydramine is highly anticholinergic, with clearance reduced among those of advanced age," and the 2023 AGS Beers Criteria tell that age group to avoid first-generation antihistamines outright — use the topical itch control on this page and take a sleepless night itch to your clinician instead. Never combine with any other diphenhydramine product, "even one used on skin" — that includes anti-itch creams containing diphenhydramine. Note what the label actually claims: it relieves symptoms "due to hay fever or other upper respiratory allergies" and the common cold; scabies itch is not a labeled OTC use, so this is symptom relief borrowed from clinical practice. Ask a doctor before use with "a breathing problem such as emphysema or chronic bronchitis," "glaucoma," or "trouble urinating due to an enlarged prostate gland." "Avoid alcoholic drinks"; "alcohol, sedatives, and tranquilizers may increase drowsiness"; "be careful when driving a motor vehicle or operating machinery." And "excitability may occur, especially in children."

A cheap skin protectant that cools and dries weeping, excoriated skin. Its honest role in scabies is the scratched-raw areas, especially in kids under 2 who cannot use OTC hydrocortisone at all, or anyone already at the 7-day hydrocortisone limit. Shake, clean and dry the skin, apply with cotton or a soft cloth as often as needed. It is not a drug for the mite and it does not claim to be.

The OTC Drug Facts panel: Active ingredients "Calamine 8% Zinc Oxide 8%," Purpose "Skin protectant," Uses "Dries the oozing and weeping of poison: ivy, oak, sumac." Directions: "Adults and children of 2 years of age and older: Shake well before using. Cleanse the skin with soap and water and dry the area before application. Apply lotion to the affected area using cotton or soft cloth, as often as needed for comfort."

Caution: Its labeled use is poison ivy, oak and sumac — scabies is not on the panel, so this is comfort care only. "Children under 2 years of age: Consult a doctor before use." When using this product, "do not get into eyes." Stop use and ask a doctor if "condition worsens" or "symptoms last more than 7 days or clear up and occur again within a few days." If you are relying on calamine because you have not been diagnosed yet, you are treating a symptom while an infestation spreads through your household.

Two of the most-searched "natural scabies cures," and neither is an FDA-approved scabicide in the form you can buy. Medical sulfur for scabies is a prescribed 5% to 10% ointment, mainly for babies too young for permethrin — that is not the same thing as a cosmetic sulfur soap bar you rinse off in the shower. Tea tree oil has killed mites in vitro and has been used in Australia as an add-on to prescription therapy in stubborn crusted scabies, but it has never been shown to cure ordinary scabies in a randomized trial.

AAD lists real sulfur as a prescription option — "Sulfur ointment (5% - 10%): While many patients dislike the odor, this treatment can be used in babies younger than 2 months of age." The 2016 American Journal of Tropical Medicine and Hygiene review of tea tree oil says it "has demonstrated promising acaricidal effects against scabies mites in vitro and has also been successfully used as an adjuvant topical medication for the treatment of crusted scabies," and concludes: "On the strength of existing data for TTO, larger scale, randomized controlled clinical trials are warranted." CDC's position on the category is unchanged: "No non-prescription products have been tested and approved to treat scabies."

Caution: The harm here is delay, not toxicity: every week spent on a soap bar is another week of transmission to everyone sharing your bed, towels or clothing, and another week for a treatable rash to become an infected one. Tea tree oil is an adjuvant in the published work, never a substitute for a scabicide, and undiluted essential oil on broken, excoriated skin causes contact dermatitis that is easily mistaken for treatment failure. If you want sulfur, ask for the 5–10% ointment by prescription — it is the one option AAD says "can be used in babies younger than 2 months of age," which is precisely where permethrin is not established.

Nothing you should do. These are insecticide products marketed for your mattress, sofa and carpet, and CDC prohibits them by name for scabies. The mite lives in your skin, not in your house, and it does not survive long off a human body — so fumigating a room treats nothing while the infestation on your skin continues.

CDC's "What not to do" section is explicit: "Do not use insecticide sprays and fumigants to treat scabies or crusted scabies" and "Do not use over-the-counter (non-prescription) products to treat scabies. These products have not been tested and approved to treat scabies." CDC's STI treatment guideline agrees: "Fumigation of living areas is unnecessary." AAD adds a hard line on the farm-supply versions: "You should never use a scabicide used to treat crops or livestock."

Caution: Never use veterinary or agricultural permethrin or ivermectin products — horse or cattle paste, pour-on or "drench" ivermectin from a feed store — on your skin OR by mouth. FDA: "Animal ivermectin products are different formulations than those approved for humans. Due to the lack of testing of these formulations in humans, the safety of these products in humans is not known. Never use medications intended for animals on yourself or other people." People have been hospitalized after swallowing the animal paste. The free alternative works better than any spray: CDC notes mites "generally do not survive more than two to three days away from human skin," so machine-wash what you can in hot water and "seal items you can't wash or dry-clean in a closed plastic bag for several days to a week." Money spent on a fogger is money not spent on the visit that gets you the prescription that actually ends the infestation.
