Product Details

Enisyl-F® is used for treatment of Feline Herpes Virus (FHV-1). It is a palatable lysine base that comes in a unique pump for easy administration.

It is a supplement that contains a naturally occurring form of L-lysine specifically developed for cats and kittens. The L-lysine competes with arginine, an amino acid essential to the development of the herpes virus, interfering with the virus’s ability to replicate and consequently reducing the viral load.

Enisyl-F is extremely tasty and is easily accepted by most cats. It can be applied directly in the mouth, on the nose or on the paw where it can be licked off. Alternatively, you may add the product to your cat's food, if more convenient.


Each pump action delivers 1ml of Enisyl-F® paste and can be applied directly in the mouth on the nose or on the paw where it can be licked off. (Alternatively you may add the product to your cats food if more convenient) and when finished replace the cap securely on the tip of the dosing pump.

For kittens: Give one pump (250mg) twice daily

For cats 6 months or older: Give two pumps (500mg) twice daily

What our vet says

What our vet says
"If your cat has Feline Herpes, spray this into their mouth, on their paw to be licked off or into their food. Feline Herpes is contagious and can cause cat flu and other infections, so it's important to treat this. Stress can be a factor in reactivating this virus in your cat so an extra cuddle is also prescribed!"
