Safety
POLYMAST RESIDUE WARNING:
Milk that has been taken from animals during treatment and for 72 hours (6 milkings) after the latest treatment must not be used for food. Treated animals must not be slaughtered for food until 10 days after the last treatment.
PRECAUTION: Because it is a derivative of 6-aminopenicillanic acid, PolyMast has the potential for producing allergic reactions. Such reactions are rare; however, should they occur, treatment should be discontinued and the subject treated with antihistamines, pressor amines, such as epinephrine or corticosteroids. The drug does not resist destruction by penicillinase and, hence, is not effective against strains of staphylococcus resistant to penicillin G.
Caution: Federal law restricts this drug to use by or on the order of a licensed veterinarian.
PolyMast® (hetacillin potassium) vs. Spectramast® LC (ceftiofur hydrochloride) Noninferiority Study
A peer-reviewed, noninferiority trial compared hetacillin potassium (the active ingredient in POLYMAST) and ceftiofur hydrochloride (SPECTRAMAST LC).
The trial concluded that the two treatments had no significant difference in overall clinical and bacteriological cure rates.2
The Unique Opti-Sert® Protective Cap
- Helps prevent introduction of harmful surface bacteria into the teat canal
-
Provides the convenience of partial or full insertion
-
Partial insertion of mastitis tubes is proven to reduce new mastitis infections by up to 50 percent1
