(pyrantel pamoate) paste
Read Entire Package Insert Carefully Before Using This Product
DESCRIPTION: 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.
COMPOSITION: Pyrantel pamoate is a compound belonging to a family classified chemically as tetrahydropyrimidines. It is a yellow, water-insoluble crystalline salt of the tetrahydropyrimidine base and pamoic acid containing 34.7% base activity. The chemical structure and name are given below.
Chemical name: (E)-1,4,5,6-tetrahydro-1-methyl-2-[2-(2-thienyl)-vinyl]-pyrimidine 4,4’ methylenebis [3-hydroxy-2-naphtholate] (1:1)
INDICATIONS FOR USE: 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.
DOSAGE AND TREATMENT: 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.
Body Weight Range
mg Pyrantel Base
up to 300 lb
1/4 syringe (5 mL)
1/2 syringe (10 mL)
3/4 syringe (15 mL)
1 full syringe (20 mL)
Note: Position screw-gauge over appropriate mark on plunger. Each mL contains 180 mg of pyrantel base as pyrantel pamoate.
Do not underdose. Ensure each animal receives a complete dose based on a current body weight. Underdosing may result in ineffective treatment, and encourage the development of parasite resistance.
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: 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 the 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.
EFFICACY: Critical (worm count) studies in horses demonstrated that Strongid paste administered at the recommended dosage was efficacious against mature infections of Strongylus vulgaris (>90%), S. edentatus (69%), S. equinus (>90%), Oxyuris equi (81%), Parascaris equorum (>90%), and small strongyles (>90%).
WARNINGS: Do not use in horses intended for human consumption.
Keep out of reach of children.
It is recommended that severely debilitated animals not be treated with this preparation.
OTHER WARNINGS: Parasite resistance may develop to any dewormer, and has been reported for most classes of dewormers. Treatment with a dewormer used in conjunction with parasite management practices appropriate to the geographic area and the animal(s) to be treated may slow the development of parasite resistance. Fecal examinations or other diagnostic tests and parasite management history should be used to determine if the product is appropriate for the herd prior to the use of any dewormer. Following the use of any dewormer, effectiveness of treatment should be monitored (for example, with the use of a fecal egg count reduction test or another appropriate method). A decrease in a drug’s effectiveness over time as calculated by fecal egg count reduction tests may indicate the development of resistance to the dewormer administered. Your parasite management plan should be adjusted accordingly based on regular monitoring.
RECOMMENDED STORAGE: Store at controlled room temperature 15°-25°C (59°-77°F).

GENERAL INFORMATION: This product has been shown to be effective for the vaccination of healthy horses, cattle, sheep, goats, and swine against tetanus. This product was licensed prior to the requirement to establish a minimum age for use. The duration of immunity is unknown. For more information regarding efficacy and safety data, see productdata.aphis.usda.gov.
Safety in pregnant animals is unknown.
Tetanus Toxoid is prepared by detoxifying tetanus toxin in such a manner as to allow the antigenic properties to remain intact. Product is purified, concentrated and adjuvanted to provide a low dose effective immunizing agent.
Each serial is tested for purity, safety, and potency in accordance with USDA requirements.
Tetanus is caused by a neurotoxin produced by growth of Clostridium tetani, an anaerobic (lives without air) micro-organism, in necrotic tissue. Affected animals become stiff, have difficulty swallowing, and have an increased pulse rate. Breathing is labored. Spasmodic contractions of the muscular system occur, such as contracting muscles of the jaw.
Spasmodic contractions of the muscular system occur, such as contracting muscles of the jaw. Thus, the term “lockjaw” is often used. Legs and tail are often stiff with abdominal muscles contracted. Tetanus stricken animals may be unusually sensitive to light and heat. Temperature of the animal generally remains normal, elevating only shortly before death.
Protective antibody levels usually occur about two weeks after the second injection of the primary immunization series. In contrast, administration of Tetanus Antitoxin is recommended for immediate, emergency, passive treatment of exposed animals with unknown vaccination history or with signs of tetanus infection.
DIRECTIONS: Do not vaccinate within 21 days before slaughter. Store at 2-8° C. Do not freeze. Do not mix with other products. Shake well before use. Use entire contents when first opened.
PRECAUTIONS: A transitory local reaction may occur at injection site. Anaphylactoid reaction may occur following administration of products of this nature. If noted, administer adrenalin or equivalent. In case of human exposure, consult a physician.
DOSAGE & ADMINISTRATION: For primary immunization, two doses should be administered subcutaneously or intramuscularly approximately 30 days apart. Use intramuscularly for horses as local reactions are more likely to occur if injected subcutaneously.
Horses: 1 ml IM
Cattle: 1 ml SC or IM
Sheep, Goats, Swine: 0.5 ml SC or IM
Historically, annual single dose revaccination has been recommended. Contact veterinarian for advice.
OTHER INFORMATION: Contains thimerosal and formalin as preservatives. Tetanus Toxoid Concentrate is available in single dose size packaged 10 vials to the carton, and in 10 dose vials.
