Do not use if

Contraindicated in patients with known hypersensitivity to pyrethrins, piperonyl butoxide, or any component of the formulation. Not recommended for use on infants under 2 years without medical supervision.

Side effects

Generally well-tolerated. May cause mild skin irritation, erythema, or allergic contact dermatitis at the application site. Avoid contact with eyes and mucous membranes.

Warnings

For external use only. Keep away from eyes. Do not use on broken, infected, or inflamed skin. Resistance to pyrethroids has been reported in some louse populations; consider alternative treatments if no improvement occurs.

How it works

Tetramethrin is a synthetic pyrethroid insecticide that disrupts nerve membrane sodium channels in lice, causing paralysis and death. Piperonyl butoxide is a synergist that inhibits cytochrome P450 enzymes in insects, preventing metabolic degradation of tetramethrin and enhancing its efficacy.
