Recommended for long term management of chronic inflammatory conditions.

DURALACTIN® Feline L-lysine contains MicroLactin®, a patented dried milk protein concentrate derived from hyperimmunized cows that contains factors that appear to block cytokines and inhibit neutrophil participation in the inflammatory response. DURALACTIN®Feline L-lysine also contains L-lysine that competes with arginine.

Recommended Dosage:

Adult cats:

2.5 ml (one notch or line on syringe) twice a day


1.25 ml (1/2 notch on syringe) twice a day

Each notch or line on syringe will deliver 2.5 ml.

Using the Syringe:

Each line on the syringe corresponds with a notch that fits the wheel. The

ring should be placed towards the wider part of the syringe. If the ring is at the top of the plunger, turn it to meet the wider part of the syringe, closest to the cap.

Turn the ring to the next line or notch on the syringe to deliver 2.5 ml. If 1.25 ml is desired, turn the ring between the lines or notches. Remove the cap and press the plunger of the tube to dispense the paste into the cat’s food. The paste may be mixed with food. Some cats may prefer the paste directly from the tube.

If the cap is difficult to remove, wrap a cloth around it and pull. Some paste may continue to come out of the syringe after the ring is flush with the syringe. This is normal and will stop once the cap is replaced. When turning the ring for the last dose, it may be necessary to turn the ring firmly to get to the end of the plunger.


For use in cats only.

Keep out of the reach of other animals and children. In case of accidental overdose, contact a health professional immediately.
