• Veterinary Use: It is approved for administration to a variety of animals, including sheep, cattle, horses, fish, dogs, and cats.

• Human Use: While primarily a veterinary medication, it is also prescribed by doctors for human use to treat parasitic worm infections.

• Administration: Tablets should generally be swallowed whole with food and not crushed or broken, according to some sources.

• Prescription: Dosage and use in both humans and animals should be determined by a healthcare professional or veterinarian, as it is often a prescription guideline medicine.

• Safety Notes: It should not be taken during pregnancy as it can be harmful to an unborn baby, and a doctor may monitor blood counts and liver function during treatment.
