Indications for Use, Specifying the Target Species
A broad spectrum anthelmintic for use in horses and donkeys for the control and treatment of adult infections of large and small strongyles, Oxyuris, Parascaris and Anoplocephala perfoliata.
Effective against benzimidazole resistant strains of small strongyles.
Not for use in horses with known hypersensitivity to the active ingredient.
Special warnings for each target species
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 body weight, 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 anthelmintics belonging to another pharmacological class and having a different mode of action should be used.
Resistance to pyrantel has been reported in cyathostomes in horses (also widespread in the US and Canada). Therefore the use of this product should be based on a local (regional, farm) epidemiological information about susceptibility of nematodes and recommendations on how to limit further selection for resistance to anthelmintics.

Interaction with other medicinal products and other forms of interaction
Amounts to be administered and administration route
Strongid-P Paste is recommended for direct oral administration in horses, ponies, donkeys and foals over four weeks of age. It is not necessary to withhold any feed prior to administration. The following method of administration is recommended:
Position the locking ring over the appropriate mark on the plunger.
Remove the cap from the nozzle.
The paste is best deposited on the upper surface of the tongue. Introduce the nozzle end of the oral doser at the corner of the mouth. Direct the oral doser backwards and depress the plunger to deposit the paste onto tongue. Providing the paste is given in this way it is unlikely that any rejection will occur. Raising the head by a hand under the chin sometimes helps with swallowing.
For the control and treatment of strongyles Oxyuris and Parascaris but excluding Anoplocephala (tapeworm). Strongid-P Paste should be used at a dose rate of 19 mg pyrantel embonate per kg bodyweight.Bodyweight rangeDose – contents ofDose of pyrantel embonateUp to 150kg¼ oral doser2.85g151 – 300kg½ oral doser5.70g301 – 450kg¾ oral doser8.55g451 – 600kgFull oral doser11.40g

Strongyles. Oxyuris and Parascaris.
Foals: one to eight months of age - dose every four weeks.
Horses and donkeys: over eight months of age - routinely dose every six to eight weeks, but during the summer and autumn when horses and donkeys are at grass, dose every four to six weeks. Always dose three to four days before turning out after in-wintering.
Suckler mares: It has been shown that reduction of strongyle challenge to the suckling foal at pasture can be achieved by using clean pasture (re-seeded, or not grazed the previously year by horses), dosing the mare three to four days before turning out and then at intervals of two to four weeks until the end of autumn.
Ideally mares with foals should go out to “clean” pasture or, if this is not possible delay, turning them out until June.
Dosage: For the control and treatment of tapeworms: Strongid-P Paste should be used at a dose rate of 38 mg pyrantel embonate per kg bodyweight, that is twice the dose rate for strongyles.
Dosing programme – Tapeworm: The need for re-treatment may vary, but if considered necessary should be carried out after an interval of six weeks.
To ensure administration of a correct dose, body weight should be determined as accurately as possible; accuracy of the dosing device should be checked.
Overdose (symptoms, emergency procedures, antidotes), if necessary
The product has an extremely wide safety margin and overdosage should not produce any adverse reactions.
Horse meat: zero days.
Pyrantel embonate is a member of the tetrahydropyrimidine class of anthelmintic compounds. It possesses broad spectrum activity against the major gastro-intestinal helminths of animals and man.
It is effective against the following gastro-intestinal helminths of foals, adult horses and donkeys.
Large and small strongyles (including benzimidazole-resistant strains of small strongyles)
Pyrantel acts as a potent agonist at acetylcholine (ACh) receptors on muscle cells of nematodes leading to neuromuscular block characteristic of depolarising agents. This results in a prolonged spastic paralysis of the worm and expulsion from the host.
Pyrantel embonate is relatively insoluble and poorly absorbed from the gut. Its activity is confined to parasites dwelling within the gut lumen. The small amount of pyrantel absorbed into the circulation is rapidly metabolised and the drug metabolites have no toxic potential.

Below are some recent questions we've received regarding Strongid P Horse and Donkey Wormer, including answers from our team.
How do I worm a lactating mare with a one month old foal with Strongid-P? Do both mare and foal get a dose each or if I give the mare a dose, will the foal receive some through the mare's milk?
You will need to dose the mare and foal separately according to their bodyweight. It is safe to give foals Strongid P from 4 weeks of age.
My horse is suffering with pinworm I have used Strongid p thelast two times as I find this expels them the best last time was a double dose in mid October can I do it again or should I use something else x I really need to try eradicate them they drive her mad xx
A Pyrantel based wormer such as Strongid P or Pyratape P is the best thing to use so you are doing the right thing. I would double dose with either one of these at 2 weekly intervals until you have eradicated the pinworm. Cleaning around her bottom daily will remove eggs laid by the adult worms overnight. You could also speak to your vet about an ivermectin and propylene glycol wash to apply around the bottom also.
Which is the most effective wormer against threadworm?
If you mean the neck threadworm (Onchocerca spp.) then Eqvalan is licensed to treat them and would be the usual choice. It is also theoretically helpful to try and reduce midges biting your horse, as they are responsible for transmitting this parasite. Good fly repellents based on a high concentration of DEET are probably the best. NAF Off DEET Power is a good example.
