One administration of the recommended dose rate of QUEST (moxidectin) 2% Equine Oral Gel also suppresses strongyle egg production through 84 days. QUEST is indicated for use in horses and ponies, including breeding mares and stallions, and foals six months of age and older.


Consult your veterinarian for assistance in the diagnosis, treatment, and control of parasitism. For best control of parasites, all horses and ponies should be included in a strategic treatment program, with particular attention given to high performance animals, brood mares, stallions and foals. In foals, initial treatment is recommended at 6 months of age, after which they should be included in a recurrent treatment program. Because QUEST provides effective control of the mucosal stages of small strongyles (encysted cyathostomes), it is useful in reducing the frequency of treatment required for successful strategic equine parasite control. A veterinarian can assist in preparing the best program for your needs.

QUEST 2% Equine Oral Gel when used at the recommended dose rate suppresses strongyle egg production through 84 days following a single oral administration. This residual strongyle control reduces pasture contamination and provides a period of protection from reinfection for horses and ponies maintained on the same pasture.


QUEST 2% Equine Oral Gel acts by interfering with chloride channel-mediated neurotransmission in the parasite. This results in paralysis and elimination of the parasite. Moxidectin is safe for use in horses and ponies because it does not have the same injurious effect on the mammalian nervous system.


QUEST (moxidectin) 2% Equine Oral Gel is specially formulated as a palatable gel which is easily administered to horses and ponies. QUEST Gel is packaged in ready-to-use SURE-DIAL® syringes. The syringe is calibrated in 50-pound increments, up to 1500 pounds. This enables the administration of the recommended dose level of 0.4 mg moxidectin/kg body weight by choosing a setting consistent with the animal’s weight.

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.


Since the dose is based on the weight of the animal, you need to use a scale or weight tape to find each animal’s weight before treating with QUEST Gel. Once the weight is known, set the dose for each horse or pony as follows.

1. Hold the syringe with the capped end pointing to the left and so that you can see the weight measurements and tick marks (small black lines). Each tick mark relates to 50 lb of body weight.

2. Turn the white dial ring until the left side of the ring lines up with the weight of the animal. In the diagram below, the dial ring is set to dose a 500 lb animal.


1. Make sure there is no feed in the animal’s mouth.

2. Remove the cap from the end of the syringe. Save the cap for reuse.

3. Place the tip of the syringe inside the animal’s mouth at the space between the teeth.

4. Gently push the plunger until it stops, depositing the gel on the back of the tongue.

5. Remove the syringe from the animal’s mouth and raise the animal’s head slightly to make sure it swallows the gel.

6. Replace the syringe cap.


If the first animal you treat weighs less than 1500 lb, there will be gel left in the syringe. You can use this gel to treat other horses or ponies. To set the next dose, add the weight of the animal you want to treat to the dose setting already on the syringe. For example, if the syringe was first used to treat a 250 lb animal, the white dial ring is set on 250 lb. To treat a 500 lb animal next, move the white dial ring to the 750 lb marking (250+500=750). You need more than one syringe to treat horses weighing more than 1500 lb.


QUEST (moxidectin) 2% Equine Oral Gel can be safely administered at the recommended dose of 0.4 mg moxidectin/kg body weight to horses and ponies of all breeds at least 6 months of age or older. Transient depression, ataxia and recumbency may be seen when very young or debilitated animals are treated. In these instances, supportive care may be advisable.

Reproductive safety studies demonstrate a wide margin of safety when the product is used in the treatment of estrual and pregnant mares and breeding stallions.

To report adverse drug reactions or to obtain a copy of the Safety Data Sheet (SDS) call 1-888-963-8471.


Care should be taken to avoid the release of significant volumes of moxidectin into either ground or free-running water since moxidectin may be injurious to aquatic life. SURE-DIAL® syringes and their contents should be disposed of in an approved landfill or by incineration.


QUEST 2% Equine Oral Gel has been formulated specifically for use in horses and ponies only. This product should not be used in other animal species as severe adverse reactions, including fatalities in dogs, may result.


Extreme caution should be used when administering the product to foals, young and miniature horses, as overdosage may result in serious adverse reactions. Do not use in sick, debilitated, or underweight animals. Do not use in horses intended for human consumption.


Not for use in humans. Keep this and all drugs out of the reach of children. Do not ingest. If swallowed, induce vomiting. Wash hands and contaminated skin with soap and water. If accidental contact with eyes occurs, flush repeatedly with water. If irritation or any other symptom attributable to exposure to this product persists, consult your physician.


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.


QUEST 2% Equine Oral Gel is available in one syringe applicator size. Each SURE-DIAL® syringe contains 0.5 oz (14.4 g) of QUEST 2% Equine Oral Gel which is sufficient to treat a single horse weighing up to 1500 lb, or two or more lighter animals with a combined body weight of up to 1500 lb.

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

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.
