More Pediatricians Prescribe Spinosad Topical Suspension 0.9%

Superiority Over Nix®

In two multicenter, randomized, controlled clinical studies under actual-use conditions, significantly more patients using Spinosad Topical Suspension 0.9% were lice-free (no live lice, adults or nymphs) 14 days after the last treatment without nit combing compared to permethrin with combing, 84.6% vs. 44.9% and 86.7% vs. 42.9%, respectively (P<0.001).2

Safety from the Ground Up

The active ingredient in Spinosad Topical Suspension 0.9%, spinosad, derives from a naturally occurring soil microorganism3 that differs from neurotoxic agents such as permethrins and pyrethrins4:

Infographic for Spinosad
  • The compound, spinosad, is not systemically absorbed, even in patients as young as six (6) months of age5
  • Spinosad targets lice and nits where they live, never penetrating beyond the stratum corneum, before breaking down through desquamation2
    • In a Phase 1 clinical trial, 14 subjects, 4-15 years of age, applied a single topical (scalp) treatment of spinosad 1.8% (twice the active amount of the compound in Spinosad Topical Suspension 0.9%) for 10 minutes. Results demonstrated no systemic absorption of spinosad2
  • There is no evidence of neurotoxicity, developmental/reproductive toxicity, immunotoxicity, mutagenicity, or carcinogenicity from spinosad exposure2

Spinosad Topical Suspension 0.9% has also demonstrated similar or lower treatment-related AEs than Nix® (permethrin 1%), the leading OTC medication.6

*Statistically significant (3.1% vs. 6.8%; p=0.007)
There is no known resistance to the compound, spinosad, in head lice and cross-resistance with other insecticides has not been reported for spinosad.<sup>7</sup>

There is no known resistance to the compound, spinosad, in head lice and cross-resistance with other insecticides has not been reported for spinosad.7

Indication
Spinosad Topical Suspension 0.9% is a pediculicide indicated for the topical treatment of head lice infestations in patients six (6) months of age and older.

Adjunctive Measures
Spinosad Topical Suspension 0.9% should be used in the context of an overall lice management program:
• Wash (in hot water) or dry clean all recently worn clothing, hats, used bedding and towels
• Wash personal care items such as combs, brushes, and hair clips in hot water
• A fine-toothed comb or special nit comb may be used to remove dead lice and nits.

Important Safety Information
Spinosad Topical Suspension 0.9% contains benzyl alcohol and is not recommended for use in neonates and infants below the age of 6 months. Systemic exposure to benzyl alcohol has been associated with serious adverse reactions and death in neonates and low birth-weight infants when administered intravenously. Most common adverse events were: application site redness (3%), eye redness (2%) and application site irritation (1%).
