Loteprednol is an ophthalmic corticosteroid suspension or eye drops used to treat eye swelling caused by surgery, infection, allergies, and other conditions. FDA pregnancy category C.
I couldn't find anything specifically about Loteprednol and breastfeeding but the following is generally about all corticosteroids.
The safety of using corticosteroids while breastfeeding depends on the type of corticosteroid and the form in which it is being used. When taken by mouth or injection, for example, the drugs pass into breast milk and may cause growth problems in nursing babies. Creams, gels, and other forms that are applied to the skin are not known to cause problems in nursing babies whose mothers use them. However, these medicines should not be applied to the breasts just before breastfeeding.

Fusidic Acid has not been specifically studied in women who are pregnant or breastfeeding. However, the amount of medicine that passes into the bloodstream after applying eye drops is negligible, and fusidic acid has been widely used by pregnant and breastfeeding women for many years with no apparent harmful effects.
http://www.netdoctor.co.uk/medicines/100001113.html Benzalkonium Chloride is used primarily in hand or face washes. Benzalkonium chloride is a synthetic germicides belonging to the large group of germicides known as Quats. Quats have been around for the past 70 years and have been such a huge success that they are now found in literally tens of thousands of cleaning products, disinfectants, and a wide range of personal care and first aid products.
