Description

Enisyl-F Oral Paste is a veterinarian-recommended supplement specially formulated to help manage symptoms associated with feline herpesvirus type 1 (FHV-1). While FHV-1 is a lifelong condition, consistent support with L-Lysine can reduce viral replication, helping minimize outbreak severity, shorten recovery time, and lower the frequency of recurrences.

Why Your Cat May Need Enisyl-F

Once infected, cats carry the feline herpesvirus for life. During outbreaks, they may experience:

  • Runny eyes and nasal discharge
  • Sneezing and congestion
  • Fever and lethargy
  • Loss of appetite
  • Oral ulcers or tongue sores

Kittens, senior cats, and immunocompromised felines are especially susceptible.

How Enisyl-F Works

Each dose contains L-Lysine, an amino acid that helps block viral replication. By interfering with the virus's ability to reproduce, Enisyl-F supports faster recovery and helps reduce symptom severity during flare-ups.

Key Benefits

  • Helps reduce the severity and duration of FHV-1 outbreaks
  • Supports a healthy immune response in cats
  • Palatable, easy-to-administer oral paste
  • Convenient metered pump for accurate dosing
  • Safe for kittens and adult cats

Indications

Enisyl-F Oral Paste is indicated for cats requiring immune system support to manage the clinical signs of feline herpesvirus infections, including upper respiratory symptoms.

Why Choose Enisyl-F Oral Paste

Enisyl-F is a safe, affordable, and highly palatable option for long-term feline immune health. The unique pump dispenser ensures consistent dosing and makes supplementation easyeven for finicky cats.

Great product
June 19, 2025
I use this for my cat every day. It has really helped with his wheezing and breathing. This product is well taken and easy to administer, much, much better than the dry kibble style which he refused to even try after a sniff.
Pros
  • Taste must be palatable, my cat readily eats/licks it.
