The neomycin, polymyxin B sulfate, and bacitracin zinc
ophthalmic ointment was discontinued, and an ophthalmic ointment containing polymyxin B sulfate and oxytetracycline hydrochloride (topically OU q12h for 10 days, Terramycin, Pfizer Inc) was started for treatment of the suspected Mycoplasma species conjunctivitis.
Topical bacitracin zinc
(Bacitracin), a triple ointment of neomycin sulfate, bacitracin zinc
, and polymyxin B sulfate (Neosporin), and silver sulfadiazine (Silvadene) were compared with petrolatum as a control in a well-conducted RCT of 426 patients with uncomplicated wounds seen at a military community hospital.
This was based on the fact that the Commission advisory committee, the Scientific Steering Committee found there were insufficient grounds to ban virginiamycin and was not consulted on the risks associated with bacitracin zinc
when the legislation was being drawn up.
The prohibition applies to tylosin phosphate, spiramycin, virginiamycin and bacitracin zinc
and took effect on January 1, 1999.
In Britain's case, the four antibiotics - Tysolin Phosphate, Bacitracin Zinc
, Spiramycin and Virginiamycin - will be outlawed from July 1 1999.
