This precise formulation delivers an all-in-one internal and external parasite routine in a single chew. One tablet simultaneously covers external parasites (fleas, ticks, and mites) and internal parasites (roundworms, hookworms, lungworm, and heartworm). For dog owners managing multiple parasite risks, that means fewer products, simpler routines, and no missed doses. Simparica Trio is prescribed for dogs suffering from, or at risk from, mixed external and internal parasitic infestations. It is indicated when treatment against ticks, fleas or mites and gastrointestinal worms is needed at the same time. If your dog only requires flea and tick protection without intestinal worm or lungworm coverage, standard Simparica is typically prescribed instead. The tablets are reddish-brown, highly palatable, and easy to give by hand or mixed into food. Do not divide or split the tablets. **Simparica Trio Ingredients:** Sarolaner, Moxidectin, Pyrantel Embonate Legal Category: AVM-GSL [View the Summary of Product Characteristics (SPC) information for this product](https://www.noahcompendium.co.uk/?id=-453586)
