Supplementation with L-lysine helps cats recover from infection and reduces the severity and frequency of recurrences. L-lysine is effective because it competes with arginine, an amino acid essential to development of the herpes virus. L-lysine interferes with the virus’ ability to replicate. L-lysine lessens the symptoms of FVH-1, reduces viral shedding during stress and reduces the frequency of flare ups.
Supplementation with L-lysine is quite simple and results are typically seen quickly. To prevent recurrences, most L-lysine products are recommended for long term use. Some products may reduce dosage in between flare-ups.The initial success with L-lysine has led to the development of many treatment methods.
These effective products contain L-lysine for cats and kittens:
Duralactin L-lysine. Poultry flavored paste with added Microlactin
Enisyl-F Paste. Tuna flavored paste
Viralys Gel. Maple flavored gel
Enisyl-F Lysine Treats. In a base of poultry meal, rice flour and corn flour
Viralys Powder. In a palatable flavor base. Add to pet food
I have had particular success with Duralactin L-lysine. Kittens like the flavor. The notched dial syringe makes it easy to administer. We usually see symptoms subside within one week of use. Let me know if you’ve found a successful strategy against feline herpes virus. Lori H
