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 (Pfizer Animal Health)

Active Ingredient(s):

Pyrantel Pamoate (180 mg pyrantel pamoate in 20 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.

How this product should be used:

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), and 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:

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.
