Lysine helps halt the replication of herpesvirus in your pet. It is typically administered to cats. It is effective against conjunctivitis (inflammation of the eye) that is associated with the herpesvirus. Always discuss the dosage of over the counter L-Lysine with your veterinarian, as it is different in pets than the label for humans recommends. Lysine coats the herpesvirus and interferes with another amino acid known as arginine, which the virus needs in order to replicate. Keep in a tightly sealed container at room temperature. Give the dose as soon as possible. If it is almost time for the next dose, skip the missed dose, and continue with the regular schedule. Do not give your pet two doses at once. Lysine may react with these drugs: Use caution when purchasing over the counter Lysine! Ensure that the product does not contain propylene glycol, as this may cause reactions in cats. USE CAUTION WHEN ADMINISTERING THIS DRUG TO PETS WITH KIDNEY OR LIVER DISEASE

The short answer is we don;t entirely know. A recentstudy published in April out of UC Davis looked atfeeding a lysine supplemented vs a basal diet for a 52day period. Arginine levels were statisticallysignificantly lower in cats fed the lysinesupplemented diet, but no adverse effects wereclinically evident. The authors state that thesupplemented diet provided approximately rheequivalent of 500-mg lysine twice a day. Furtherstudies are needed to know what the long term (monthsor years) effects of therapy may be. As with mostlong terms medications, titrating to the leasteffective dose may be the reasonable way to go. Ifthere is concern in an individual patient, plasmaarginine levels could be measured. In my ownexperiance I have not noted any issues in catsreceiving long term lysine, but mostly I have used atotal dose of 500-mg per day.
Should I give my kitten L-Lysine? How much? | The Cat Site
amounts of L-Lysine will deplete Arginine. Arginine (an amino acid) is essential to the processing of protein; cats with arginine insufficiency cannotconvert ammonia to urea, and hence get a condition called "hyperammonemia"--an excess of ammonia in the blood: ammonia intoxication. Arginine deficiency will also lead to hyperglycemia, lethargy, vomiting, diarrhea, weakness and imbalance, and VERY rapid weight loss (sometimes as much as 5-10% body weight in 24 hours). Cats, as carnivores, are extremely sensitive to arginine deficiency. Please do not over-supplement L-Lysine. The recommended dosage for cats w/FHV is 500 mg/day. Do not give any more than that without explicit instructions from your veterinarian.
