Lysine for Cats

What is Lysine for Cats?

Lysine is an essential amino acid commonly used to manage symptoms of feline herpesvirus (FHV-1), a viral infection that can cause respiratory issues and eye problems in cats. It works by inhibiting the replication of the virus, thereby reducing the severity of flare-ups. Lysine is often available as a supplement in various forms, including powders, gels, and chews, and is manufactured by several well-known pet health brands.

Active Ingredients

The active ingredient in lysine supplements is L-lysine. This amino acid competes with L-arginine, which the herpesvirus needs to replicate. By limiting the availability of L-arginine, lysine helps to reduce the replication of the virus, easing symptoms like sneezing, nasal discharge, and conjunctivitis in cats infected with FHV-1.

How to Use Lysine for Cats

  1. Administration: Lysine is available in several forms, including powders, gels, and chews. Use the form that your cat will tolerate best.
  2. Dosage: The standard dosage for adult cats is typically 250-500 mg per day, but always follow your veterinarian’s guidance.
  3. Storage: Keep lysine supplements in a cool, dry place, away from direct sunlight. Ensure the container is tightly sealed.

Lysine Indications & Contraindications

Lysine is indicated for managing symptoms of feline herpesvirus, including upper respiratory issues and eye discharge. It should not be used in cats with kidney disease or other metabolic conditions. Always consult with your veterinarian to ensure it’s safe for your cat.

Effectiveness

Lysine may reduce the frequency and severity of herpesvirus flare-ups, but its effectiveness can vary. Some studies have shown mixed results, and lysine may be most beneficial as part of a broader treatment plan for FHV-1.

Adverse Reactions

Side effects of lysine are rare but can include gastrointestinal upset, such as vomiting or diarrhea. If any side effects occur, contact your veterinarian promptly for advice.

Dosage & Safety Information

The general dosage for adult cats is 250-500 mg daily, with adjustments made for kittens or those with specific health conditions. Ensure the product is stored properly and used before its expiration date to maintain effectiveness.

What happens if I miss a dose?

If a dose is missed, administer it as soon as you remember, unless the next dose is due soon. Do not double the dose to make up for a missed one.

Can it be used on kittens?

Yes, lysine can be used in kittens, but the dosage should be reduced based on their size and age. Always consult your veterinarian for proper guidance.

Can it be used on pregnant cats?

Consult your veterinarian before using lysine on pregnant cats. While lysine is generally considered safe, its effects on pregnant cats have not been extensively studied.
