The drug has been found to be safe and effective both for human and for veterinary use. Although the drug can eliminate infection in both humans and cats, its use in humans will have vey little impact on overall prevalence of human toxoplasmosis. Its use in cats, alternatively, could, at least in theory, reduce prevalence in both humans and cats.
