Feline Herpes Virus (FHV-1) :
Up to 97% of cats have serological evidence of exposure to FHV-1, which is the cause of the most widespread respiratory infection in cats, Feline Viral Rhinotracheitis (FVR). Studies demonstrate that L-lysine supplementation to cats infected with FHV-1 could reduce both clinical signs and viral shedding.

Enisyl-F is the first lysine-based nutritional supplement developed for veterinary use, presented as a very palatable paste in a     100 mL pump distributing 1 mL per pressure.


Active ingredients in Enisyl-F: 250 mg of L-Lysine Hydrochloride per mL

Nonmedicinal ingredients in Enisyl-F: Purified water, sorbitol, fish oil, xanthan gum, soya oil, tuna flavor, soya lecithin, silica aerogel, caramel colour, potassium sorbate, citric acid.

Method of administration

Adult cats : 1 to 2 mL twice a day.
Kittens : 1 mL twice a day, or as recommended by your veterinarian.

Each press of the dosing pump represents 1 mL of Enisyl-F paste. Enisyl-F is extremely palatable 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. Replace the cap securely on the tip of the dosing pump after use.
Store in a cool place.
