Intermectin Duo Paste can only be used in the first 3 months of gestation following a risk-benefit analysis by the assigned veterinarian.

Side effects

Some horses carrying heavy infections of Onchocerca microfilariae have experienced oedema and pruritus after administration, probably caused by the death of large numbers of microfilariae.
These signs resolve within a few days, but symptomatic treatment may be recommendable.
In cases of heavy infestations with tapeworms, signs of mild, transient colic and loose stool may be observed.
There have been rare reports of swelling and irritation of the mouth, lip and tongue, and of salivation following administration of Intermectin Duo Paste.
These reactions have been transitory in nature, appearing within 1 hour and abating within 24 to 48 hours following administration.


Intermectin Duo Paste is administered orally at the recommended dose rate of 0.2 mg ivermectin and 1 mg praziquantel per kg bodyweight, corresponding to 1.29 g of paste per 100 kg bodyweight in a single administration. Each applicator, containing 7.74 g of paste, delivers 120 mg ivermectin and 600 mg praziquantel, which is sufficient to treat 600 kg of bodyweight.
