More information

Parasidose is registered with Medsafe for treatment of head lice, (see http://www.medsafe.govt.nz/(external link)).

The listing of Phenothrin 0.5% shampoo is to ensure continuity of supply for treatment of head lice infestation to manage an unforeseen stock shortage of Para Plus 90 g spray. 

Note to community pharmacies

If pharmacy is presented with a prescription for Para Plus 90 g spray and this is unavailable, pharmacies will be able to substitute with Parasidose 0.5% shampoo by contacting the prescriber by phone and annotating accordingly. Alternatively, patients could go back to their prescriber to have a new prescription issued.

Note that the 100 ml bottle of Parasidose provides approximately the same number of head lice treatments as one bottle of Para Plus 90 g.
