Strongid-P paste is a broad-spectrum anthelmintic, which is indicated for use in the horse and donkey for the control and treatment of adult infections of large and small strongyles, Oxyuris, Parascaris and Anoplocephala perfoliata. Strongid-P paste is effective against benzimidazole resistant strains of small strongyles and should be used wherever the presence of such strains is suspected.

Dosage and Administration

Strongid-P is recommended for direct oral administration in horses, ponies, foals over four weeks of age and donkeys. For the control and treatment of strongyles, including benzimidazole resistant strains, Strongid-P should be used at a dose rate of 19mg per kg of bodyweight, therefore one complete syringe will provide sufficient paste to treat a 600kg horse. It is recommended that horses and ponies over eight months of age are routinely dosed every six to eight weeks, increasing to once every four to six weeks when at grass. Animals under eight months of age should be treated every four weeks.

When using Strongid-P to for the treatment and control of tapeworm, a dose rate of 38mg per kg of bodyweight should be administered, that is double the dose of that for strongyles. If considered necessary, treatment for tapeworm should be carried out at intervals of at least six weeks.

To ensure administration of a correct dose of Strongid-P, body weight should be determined as accurately as possible

Instructions for use Strongid-P Paste is recommended for direct oral administration in horses, ponies and foals of over four weeks of age and donkeys. It is not necessary to withhold any feed prior to administration. The following method of administration is recommended:

1. Position the locking ring over the appropriate mark on the plunger.

2. Remove the cap from the nozzle.

3.The paste is best deposited on the upper surface (dorsum) of the tongue. Introduce the nozzle end of the syringe at the corner of the mouth (labial commissure). Direct the syringe backwards and depress the plunger to deposit the paste onto the tongue. Providing the paste is given in this way it is unlikely that any rejection will occur. Raising of the horse's head by a hand under the chin sometimes assists in the swallowing process.
