Contains Ivermectin and Praziquantel.

The following parasites of horses are sensitive to the antiparasitic effects of EQVALAN DUO:

Tapeworms:

Large strongyles:

Adult and immature (fourth-stage larvae) small strongyles or cyathostomes, including benzimidazole-resistant strains:

Adult hairworms: Trichostrongylus axei

Adult and immature pinworms: Oxyuris equi

Adult, third- and fourth-stage larvae of roundworms (ascarids): Parascaris equorum

Microfilariae of neck threadworms: Onchocerca spp.

Adult intestinal threadworms: Strongyloides westeri

Adult large-mouth stomach worms: Habronema muscae

Oral and gastric stages of bots: Gasterophilus spp.

Adult and immature lungworms: Dictyocaulus

 Dosage and administration

The recommended dose is 200 mcg ivermectin per kg bodyweight and 1mg praziquantel per kg bodyweight (corresponding to 1.29g of paste per 100kg bodyweight in a single treatment).

Bodyweight and dosage should be accurately determined prior to treatment. The contents of one syringe will treat horses up to 600kg.

Calibrated markings are provided at 100kg bodyweight intervals. The syringe should be adjusted to the calculated dosage by setting the ring on the appropriate place on the plunger.

Parasite control program

Veterinary advice should be sought on appropriate dosing programs and stock management to achieve adequate parasite control for both tapeworm and roundworm infestations.

Dosing instructions

EQVALAN DUO oral paste is for oral administration only. While holding the plunger, turn the knurled ring on the plunger ¼ turn to the left and slide it so the stop ring is at the prescribed weight marking. Lock the ring in place by turning it ¼ turn to the right in order to bring the two arrows, the one visible on the ring and the one on the plunger rod, into alignment. Make sure the horse's mouth contains no feed. Remove the cover from the tip of the syringe. Insert the syringe tip into the horse's mouth at the interdental space and deposit the paste on the base of the tongue. Immediately raise the horse's head for a few seconds after dosing and ensure that the paste is consumed.

 

Contra-indications, warnings, etc

Safety studies were not conducted in foals younger than 2 months of age, nor in stallions, therefore EQVALAN DUO cannot be recommended for use in these categories of animals.

EQVALAN DUO has been formulated for use in horses only. Cats, dogs, especially Collies, Old English Sheepdogs and related breeds or crosses, and also turtles and tortoises may be adversely affected by the concentration of ivermectin in this product if they are allowed to ingest spilled paste or have access to used syringes.

Care should be taken to avoid the following practices because they increase the risk of development of resistance and could ultimately result in ineffective therapy:

- Too frequent and repeated use of anthelmintics from the same class, over an extended period of time.

- Underdosing, which may be due to underestimation of bodyweight, misadministration of the product, or lack of calibration of the dosing device (if any).

Suspected clinical cases of resistance to anthelmintics should be further investigated using appropriate tests (e.g. Faecal Egg Count Reduction Test). Where the results of the test(s) strongly suggest resistance to a particular anthelmintic, an anthelmintic belonging to another pharmacological class and having a different mode of action should be used.

Resistance to macrocyclic lactones (which includes ivermectin) has been reported in Parascaris equorum in horses in the EU. Therefore the use of this product should be based on local (regional, farm) epidemiological information about susceptibility of gastro-intestinal nematodes and recommendations on how to limit further selection for resistance to anthelmintics.

Some horses with heavy infections of Onchocerca spp. microfilariae have experienced oedema and pruritus following treatment, assumed to be the result of the death of large numbers of microfilariae. These signs resolve within a few days but symptomatic treatment may be advisable. In cases of heavy infestations with tapeworms, signs of mild, transient colic and diarrhoea may be observed. Following administration of EQVALAN DUO, there have been rare reports of inflammation of the mouth, lip and tongue, which results in various clinical signs such as oedema, hypersalivation, erythema, tongue disorder and stomatitis. These reactions have been transitory in nature, appearing within 1 hour and abating within 24 to 48 hours following administration. In case of severe oral reactions symptomatic treatment is recommended.

No undesirable effects related to treatment were observed in 2 month old horses treated with EQVALAN DUO at up to three times the recommended dose and in adult horses treated at ten times the recommended dose. Transient decreased food consumption, increased body temperature and impairment of vision were noticed in horses treated twice with an ivermectin oral paste at ten times the recommended dose (i.e. 2 mg/kg b.w.). All changes disappeared within five days. No antidote has been identified; however, symptomatic therapy may be beneficial.
