What is Strongid Paste?

Strongid Paste is an equine wormer that removes and controls most common and damaging internal parasites including bloodworms, small strongyles, pinworms, and large roundworms.


Horses and foals (over 2 months of age)

  • Easy to administer
  • No reported side effects
  • Convenient disposable syringe
How it works:

The active ingredient pyrantel pamoate acts as a depolarizing neuromuscular blocking agent, thereby causing sudden muscular contraction, followed by paralysis of the parasite. The parasite loses its grip on the intestinal wall and passes out of the system naturally.


Use with caution in severely debilitated animals.

Brand Name:

Strongid Paste (Zoetis)

Active Ingredient(s):

Pyrantel Pamoate (180 mg pyrantel pamoate per ml)

What is this product used for:

Strongid Paste is used in horses and foals for the removal and control of mature infections of large strongyles, small strongyles, pinworms, and large roundworms.


Strongid Paste is a non-prescription (OTC) product available as individual oral dose syringes. Strongid Paste is a pale yellow to buff paste containing 43.9% w/w pyrantel pamoate in an inert vehicle. Each syringe contains 3.6 grams of pyrantel base in 23.6 grams (20 ml) paste. Each ml contains 180 mg pyrantel base as pyrantel pamoate.

How this product should be used:

Strongid Paste is used for the removal and control of mature infections of large strongyles (Strongylus vulgaris, S. edentatus, S. equinus); small strongyles, pinworms (Oxyuris equi), and large roundworms (Parascaris equorum) in horses and ponies. Consult your veterinarian for assistance in the diagnosis, treatment, and control of parasitism.

For horses up to 300 lbs, give 1/4 syringe (5 ml). For horses 301-600 lbs, give 1/2 syringe (10 ml). For horses 601-900 lbs give, 3/4 syringe (15 ml). For horses 901-1200 lbs, give 1 syringe (20 ml).

In the event of overdose:

Contact your veterinarian or veterinary emergency room.

What are the side effects:

There are no reported side effects.

What special precautions are there:

Unprotected animals that have grazed may already have an established S. vulgaris larval infestation. These animals should be treated with a therapeutic dose of a larvicidal product. This product is not for use in horses intended for human consumption. It is recommended that severely debilitated animals not be treated with this preparation.

How should I store this product:

Store at controlled room temperature 59°-77°F (15°-25°C). Store the product in the container it comes in. Keep out of the reach of children and pets.

How to Use
  • Strongid Paste is given by mouth to horses and foals for the removal and control of mature infections of internal parasites (large and small strongyles, pinworms, and large roundworms).
  • Each oral syringe of Strongid Paste contains four 300 lb doses.
  • Strongid Paste is to be administered as a single oral dose of 3 mg pyrantel base per lb of body weight. The syringe has 4 weight mark increments. Each weight mark indicates the recommended dose for 300 lb of body weight.

Position screw-gauge over appropriate mark on the plunger. Each ml contains 180 mg of pyrantel base as pyrantel pamoate. For maximum control of parasitism, it is recommended that foals (2-8 months of age) be dosed every 4 weeks. To minimize the potential source of infection that the mare may pose to the foal, the mare should be treated 1 month prior to anticipated foaling date followed by retreatment 10 days to 2 weeks after birth of foal. Horses and ponies over 8 months of age should be routinely dosed every 6 weeks.

Administration Instructions:

After removing the cap, the paste should be deposited on the dorsum of the tongue. Introduce the nozzle end of the syringe at the corner of the mouth. Direct the syringe backwards and depress the plunger to deposit the paste onto the tongue. Given in this manner, it is unlikely that rejection of the paste will occur. Raising your horse's head sometimes assists in the swallowing process. When only part of the paste has been used, replace the cap on the syringe nozzle.


May be used in mares at any stage of pregnancy or lactation. Stallion fertility is not affected by the use of this product. Should not be given to severely debilitated horses.

Do to the fact that this is intended to be used on horses and not cats, you would want to contact your vet for the correct dosage amounts.
