Frequently Asked Questions about Spinosad

What is Spinosad used for?

Spinosad is a topical medicine used to treat head lice infestation in patients 6 months and older, and scabies in patients 4 years and older. It works by paralyzing and killing the lice or mites.

How long should I leave Spinosad on before rinsing or washing it off?

For head lice, apply Spinosad to dry hair and scalp, leave it on for 10 minutes, then rinse with warm water. For scabies, apply over the whole body from the neck down, leave on for at least 6 hours (after an initial 10-minute absorption period), then wash off, unless your physician directs otherwise.

Do I need to repeat treatment with Spinosad?

For head lice, a single application is often enough. Repeat treatment only if you still see live lice 7 days after the first application. For scabies, your physician may recommend a repeat application if signs of infestation continue, since itching can persist for weeks even after successful treatment.

Can Spinosad be used during pregnancy or breastfeeding?

Spinosad is not significantly absorbed into the bloodstream after topical use, so meaningful exposure to a fetus or infant is not expected. Still, it should be used during pregnancy only if clearly needed, and breastfeeding mothers should wash the product off the chest area with soap and water before nursing. Always consult your physician first.

Is Spinosad safe for infants?

No. Spinosad is not approved for infants under 6 months of age because the formulation contains benzyl alcohol, which can cause serious adverse effects if absorbed in larger amounts in very young infants.

What should I do if Spinosad is accidentally swallowed?

Seek immediate medical attention or contact a poison control center/emergency services right away. Do not attempt home treatment; Spinosad is intended for external use only and has no specific antidote.
