CHAPTER I--FOOD AND DRUG ADMINISTRATION, DEPARTMENT OF HEALTH AND HUMAN 
                          SERVICES (CONTINUED)
 
PART 510--NEW ANIMAL DRUGS--Table of Contents
 
          Subpart E--Requirements for Specific New Animal Drugs
 
Sec.  510.410  Corticosteroids for oral, injectable, and ophthalmic use in animals; warnings and labeling requirements.


    (a) The Food and Drug Administration has received reports of side 
effects associated with the oral, injectable, and ophthalmic use of 
corticosteroid animal drugs. The use of these drugs administered orally 
or by injection has resulted in premature parturition when administered 
during the last trimester of pregnancy. Premature parturition may be 
followed by dystocia, fetal death, retained placenta, and metritis. 
Additionally, corticosteroids used in dogs, rabbits, and rodents during 
pregnancy have produced cleft palate in offspring. Use in dogs has 
resulted in other congenital anomalies, including deformed forelegs, 
phocomelia, and anasarca. Drugs subject to this section are required to 
carry the veterinary prescription legend and are subject to the labeling 
requirements of Sec.  201.105 of this chapter.
    (b) In view of these potentially serious side effects, the Food and 
Drug Administration has concluded that the labeling on or within 
packaged corticosteroid-containing preparations intended for animal use 
shall bear conspicuously the following warning statement:

    Warning: Clinical and experimental data have demonstrated that 
corticosteroids administered orally or by injection to animals may 
induce the first stage of parturition if used during the last trimester 
of pregnancy and may precipitate premature parturition followed by 
dystocia, fetal death, retained placenta, and metritis.
    Additionally, corticosteroids administered to dogs, rabbits, and 
rodents during pregnancy have resulted in cleft palate in offspring. 
Corticosteroids administered to dogs during pregnancy have also resulted 
in other congenital anomalies, including deformed forelegs, phocomelia, 
and anasarca.
