Drontal Plus is given by mouth. Tablets may be crumbled and mixed with a small amount of food. This should be eaten before the pet receives the remainder of the meal to ensure the entire amount of medication is ingested. Fasting is neither necessary nor recommended. Always follow the dosage instructions provided by your veterinarian. If you have difficulty giving the medication, contact your veterinarian. This medication should only be given to the pet for whom it was prescribed.
