Description Feline Herpes Virus (HFV-1): HFV-1 is the causative agent of the most common respiratory infection in cats, feline infectious rhinotracheitis. Up to 97% of cats show serological evidence of exposure to this virus. Studies show that the oral administration of L-lysine to cats infected with HVF-1 would reduce the severity of clinical signs and viral excretion. Enisyl-F : Enisyl-F is the first nutritional supplement based on lysine developed for veterinary use, and presented in the form of a very palatable paste in a 100 ml pump dispensing 1 ml per pressure. Ingredients Active ingredients of Enisyl-F: 250 mg of L-lysine hydrochloride per ml Non-medicinal ingredients of Enisyl-F : Purified water, sorbitol, fish oil, xanthan gum, soybean oil, tuna flavor, lecithin powder, silica airgel, caramel color, potassium sorbate, citric acid. Administration mode Adult cats: 1 to 2 ml of Enisyl-F twice a day. Kittens: 1ml of Enisyl-F twice daily, or as recommended by your veterinarian. Each pressure on the dosing pump delivers 1 ml of Enisyl-F paste. Enisyl-F, with its very pleasant taste, appeals to most cats. It can be applied directly in the mouth, on the nose or on the paw in order to be licked off. You can also add the paste to your cat's food, if that's more convenient. Replace the cap on the pump nozzle after use. Store in a cool place.
