How long does it take drontal to work?

Drontal typically starts working within a few hours after administration, but it may take 24 to 48 hours to fully eliminate intestinal parasites. The exact time can vary depending on the type of parasite and the individual animal's health. It's important to follow the veterinarian's instructions for dosage and administration to ensure effective treatment. Always consult a vet if you have concerns about your pet's health or the medication's effects.
