Natroba™ (Spinosad) is the brand name and Spinosad Topical Suspension is the authorized generic version. Both are widely covered by Medicaid and insurance plans.
For commercial insurance patients, always prescribe Spinosad Topical Suspension.
For Medicaid patients, refer to your state PDL and prescribe either Natroba™ or Spinosad Topical Suspension authorized generic accordingly.
Today, head lice resistance to permethrin-based products found on pharmacy-aisle shelves is over 98% across 48 states.1
