As with any antimicrobial, frequent and repeated use of antiprotozoal agents of the
same class can lead to resistance development. Cross-resistance has been shown
between amprolium and anticoccidial drugs having the same mode of action. Use of
the veterinary medicinal product/amprolium should be carefully considered when
susceptibility testing has shown resistance to amprolium/anticoccidials because its
effectiveness may be reduced. As with all anticoccidials, prolonged use may result in
the development of resistant strains.
