Is Polymyxin B & Trimethoprim Ophthalmic Solution ok for pink eye in sulfa & penicillin allergies?

Pink eye (conjunctivitis) is an inflammation or infection of the conjunctiva (the membrane that lines your eyelid and covers the white part of your eyeball).
Pink eye is commonly caused by a bacterial or viral infection or an allergic reaction. It may affect one or both eyes. The main symptoms of pink eye are redness, itching, discomfort and discharge.
Your doctor will prescribe antibiotic eye drops or eye ointment if you are diagnosed with pink eye caused by bacteria. Or if your pink eye is caused by an allergy or a virus your doctor may prescribe an antihistamine or decongestant eye drop to help relieve itching and redness.
Polymyxin B and trimethoprim is a combination medicine used to treat eye infections caused by bacteria including pink eye. This eye drop is safe to use in patients who have sulfa or penicillin allergies. It is chemically unrelated.
