This medicine supplies L-lysine, an essential amino acid. Cats cannot make lysine, so they must obtain it from the diet or supplements. The treatment is often used to support cats prone to upper respiratory signs associated with feline herpesvirus (FHV-1). Evidence for symptom control can vary by cat and product. Discuss use with a veterinarian before starting or changing any regimen.

On the label, the gel is intended for oral use in cats and kittens. It can be given directly or mixed with a small amount of food. Nutri-Lys Lysine Supplement Gel is formulated to be palatable, which may help with daily use.

Who It’s For

This gel is for domesticated cats, including kittens, that need dietary lysine support. It may be considered for cats with recurring upper respiratory signs where a clinician recommends lysine as part of overall care. Avoid use in pets with known hypersensitivity to any ingredient.

• Adult cats and kittens under veterinary direction
• Not for dogs, other species, or human use
• Use caution in pregnant or lactating queens
• Discuss use in renal or hepatic disease
• Stop and seek veterinary advice if reactions occur

Dosage and Usage

Follow the product label or your veterinarian’s instructions. Give the directed amount by mouth. You may place the gel on a clean finger, a spoon, or the cat’s paw for self-licking. Mixing with a small portion of the regular meal can also work if your veterinarian agrees. Offer fresh water at all times.

Try to give doses at consistent times each day. If your cat resists, start with a small portion of the directed amount and gradually work up as advised by your veterinary professional. Do not exceed labeled directions. Contact your veterinarian if you are unsure how much to give or how often to give it.

Strengths and Forms

This product is supplied as an oral gel in tubes. Common formulations provide lysine in a flavored base for easy administration. A commonly published concentration is around 250 mg per 2.5 mL; always check your specific package. Powder forms may be available if a different texture is preferable. Many owners choose Lysine supplement gel from Canada for cats that dislike tablets.

Missed Dose and Timing

If a dose is missed, give it when remembered unless it is close to the next scheduled amount. If it is nearly time, skip the missed dose and resume the regular schedule. Do not double up. Keeping a simple dosing log can help maintain consistency.

Storage and Travel Basics

Store the tube tightly closed at room temperature as indicated on the label. Protect from excessive heat and direct sunlight. Keep out of reach of children and animals. Do not use if the safety seal is broken or missing. Check the expiration date before each new tube is started.

When you travel, keep the gel in its original carton with the label visible. Pack it in a clean, dry compartment of your bag. You may carry a copy of the label or a note from your veterinarian. Avoid leaving it in a parked car or in checked baggage that can experience temperature extremes.

What to Expect Over Time

Most cats accept the gel once they learn the routine. Some will lick it from a finger or paw; others prefer it mixed with a small portion of food.
