Worming. A task that doesn’t rank highly in the fun-o-meter but nonetheless is essential for your pet’s health. Perhaps you’ve tried a tablet or liquid wormers without much success so have decided to try out other formulas? Step forward the Panacur Paste Syringe for Dogs and Cats.


About Panacur Paste Syringe

The Panacur Paste Syringe is for the treatment of roundworms, lungworms and tapeworms in dogs, cats, puppies and kittens. Panacur paste contains the worming drug, Fenbendazole. A broad-spectrum anti-parasitic drug that is proven to be very effective in treating worms in pets. It comes in a 5g plunger syringe that must be administered orally by squeezing the paste from the syringe onto the back of the tongue after feeding.


Before use

Before using the Panacur plunger syringe, it’s important to fully assess your pet’s body weight so you know the exact recommended dosage. Depending on their size and how pliable they are, you may be able to sit them on your bathroom or kitchen scales. If you have a medium to a large sized dog or cat you may be better off taking them to the vets and making a note of the weight before purchasing your Panacur Paste.


To find the correct dose for your pet’s weight, turn the wheel around the base of the plunger anti-clockwise until you reach the desired amount needed.


Practical dosage recommendations:

For example, to treat a 4 kg cat, move the dose locking ring so that the bottom of it lines up with the eighth graduation (or line) on the syringe. Push down on the syringe plunger to deliver the correct dose. Additional syringes will be needed for dogs and cats weighing over 9 kg. For dogs and cats weighing over 9 kg, two extra syringe graduations are required for each additional 1 kg bodyweight as a single dose.


It’s recommended to repeat the treatment 2 to 4 times a year or should be repeated if you notice parasitic reinfection. Treatment every 6 to 8 weeks is advisable for dogs in kennels and cats in catteries or at breeder’s premises.

As a reduced rate of fenbendazole (25 mg per kg body weight daily) should be given for the treatment of pregnant dogs, it’s recommended that an alternative wormer is used as it cannot accurately be attained using the Panacur Paste 5 g syringe. Pregnant cats, however, can be safely treated with Panacur Paste but only require a single treatment at the routine adult dose rate.

Panacur Paste Syringe is one of the most popular wormers on the market because it is highly effective and incredibly easy it is to administer to pets, especially so for those who turn their whiskers up at tablets! Because of its simple syringe applicator, it also makes it very easy to treat puppies and kittens. Always remember to wear gloves and to wash hands after use. Also, mark on the calendar or put a reminder in your phone when your pet needs their next dose of treatment.
