Dermcare Permoxin is a permethrin-based insecticidal spray and rinse concentrate for the control of paralysis ticks, fleas, and other external parasites on dogs and horses. Available in 250ml and larger sizes, it provides flexible application as either a direct spray or diluted rinse.

When used as a rinse, Permoxin provides protection against paralysis ticks for up to three days and fleas for up to seven days. As a spray, it can be applied between rinses for additional tick protection in high-risk areas. The concentrate is diluted before use.

Permoxin contains 40g/L permethrin as its active ingredient. It is suitable for dogs and horses but must NOT be used on cats, as permethrin is toxic to felines. Particularly important in tick-prone areas of eastern Australia, Permoxin remains one of the most relied-upon tick prevention products available from veterinary suppliers.
