    (ii) Indications for use. It is used for the treatment of 
musculoskeletal conditions due to inflamation of muscles or joints and 
accessory structures where permanent structural changes do not exist, 
e.g., arthritis, osteoarthritis, disc syndrome, and myositis (in septic 
arthritis, appropriate antibacterial therapy should be concurrently 
administered); certain acute and chronic dermatoses of varying etiology 
to help control associated pruritus, irritation, and inflammation; 
otitis externa in conjunction with topical medication; allergic states, 
e.g., hives, urticaria, and insect bites; and shock and shock-like 
states by intravenous administration.
    (iii) Limitations. See paragraph (c)(1)(iii) of this section.

[[Page 266]]

Not for use in horses intended for food. For veterinary use only. 
Federal law restricts this drug to use by or on the order of a licensed 
veterinarian. Women of childbearing age, asthmatics, and persons with 
bronchial and other respiratory problems should exercise extreme caution 
when handling this product. In the early stages, women may be unaware of 
their pregnancies. Fluprostenol is readily absorbed through the skin and 
can cause abortion and/or bronchiospasms. Direct contact with the skin 
should therefore be avoided. Accidental spillage on the skin should be 
washed off immediately with soap and water.

chapter.
    (c) Special considerations. (1) Clinical and experimental data have 
demonstrated that corticosteroids administered orally or parenterally to 
animals may induce the first stage of parturition when administered 
during the last trimester of pregnancy and may precipitate premature 
parturition followed by dystocia, fetal death, retained placenta, and 
metritis.
    (2) Systemic therapy with methylprednisolone acetate, as with other 
corticoids, is contraindicated in animals with arrested tuberculosis, 
peptic ulcer, and Cushing's syndrome. The presence of active 
tuberculosis, diabetes mellitus, osteoporosis, renal insufficiency, 
predisposition to thrombophlebitis, hypertension, or congestive heart 
failure necessitates carefully controlled use of corticosteroids. 
Intrasynovial, intratendinous, or other injections of corticosteroids 
for local effect are contraindicated in the presence of acute infectious 
conditions. Exacerbation of pain, further loss of joint motion, with 
fever and malaise following injection may indicate that the condition 
has become septic. Appropriate antibacterial therapy should be 
instituted immediately.
    (d) Conditions of use--(1) Amount--(i) Intramuscular. Dosage may be 
repeated when necessary, as follows: dogs--2 to 40 milligrams (up to 120 
milligrams in extremely large breeds or dogs with severe involvement);

    (2) Indications for use. Respiratory and circulatory depression in 
dogs resulting from overdosage of, or unusual sensitivity to, morphine 
and certain other narcotics. Not for depression due to any other cause.
    (3) Limitations. Successive doses of the drug gradually lose their 
analeptic effect and eventually induce respiratory depression equal to 
that of opiates. Therefore, do not exceed therapeutic dosage. Do not mix 
drug with meperidine solutions because the buffer will cause 
precipitation. Federal law restricts this drug to use by or on the order 
of a licensed veterinarian.

    (2) Indications for use. Oxytocin may be used as a uterine 
contractor to precipitate and accelerate normal parturition and 
postpartum evacuation of uterine debris. In surgery it may be used 
postoperatively following cesarean section to facilitate involution and 
resistance to the large inflow of blood. It will contract smooth muscle 
cells of the mammary gland for milk letdown if the udder is in proper 
physiological state.
    (3) Limitations. Do not use in dystocia due to abnormal presentation 
of fetus until correction is accomplished. For prepartum usage, full 
relaxation of the cervix should be accomplished either naturally or by 
administration of estrogen prior to oxytocin therapy. Federal law 
restricts this drug to use by or on the order of a licensed 
veterinarian.

Sec. 522.2112  Sterile sometribove zinc suspension.

    (a) Specifications. The drug product consists of a single-dose 
syringe containing 500 milligrams of sometribove zinc in a sterile, 
prolonged-release suspension.
    (b) Sponsor. See No. 059945 in Sec. 510.600(c) of this chapter.
    (c) Special considerations. Use may result in reduced pregnancy 
rates and, in first calf heifers, an increase in days open. Use of the 
product has also been associated with increases in cystic ovaries and 
disorders of the uterus during the treatment period. Also, the incidence 
of retained placenta may be higher following subsequent calving. Treated 
cows are at an increased risk for clinical mastitis and subclinical 
mastitis. In some herds, use has been associated with increases in 
somatic cell counts in milk. Care should be taken to differentiate 
increased body temperature due to use of this product from an increased 
body temperature that may occur due to illness. Use may result in an 
increase in digestive disorders such as indigestion, bloat, and 
diarrhea. There may be an increase in the number of cows experiencing 
periods of ``off-feed'' (reduced feed intake) during treatment. Cows 
treated with this product may have increased numbers of enlarged hocks 
and lesions of the knee (carpal region), and second lactation or older 
cows may have more disorders of the foot region. Use has been associated 
with reductions in hemoglobin and hematocrit values during treatment. 
Human warning: Avoid prolonged or repeated contact with eyes and skin.
    (d) Conditions of use--(1) Amount. 500 milligrams of sometribove 
zinc every 14 days beginning during the ninth

week after calving and continuing until the end of lactation.
    (2) Indications for use. For use in healthy lactating dairy cows to 
increase the production of marketable milk.
    (3) Limitations. For use in lactating dairy cows only. Administer 
subcutaneously. Safety to replacement bulls born to treated dairy cows 
has not been established. To minimize injection site blemishes on 
carcass at time of slaughter, avoid injections within 2 weeks of 
expected slaughter. No milk discard or preslaughter withdrawal period is 
required.
