Polytrim Allergy In Children
Polytrim (polymyxin b and trimethoprim): Is an antibiotic for superficial eye infections. Being composed of Polymyxin B sulfate & trimethoprim sulfate, it should be used with caution in those with sulfa allergies. If using this medication, do not take vitamin b complex or folate (folic acid) supplements, as they will counter the activity of the trimethoprim. If eye condition worsens, see doc. ...Read more

Polytrim (polymyxin b and trimethoprim) good: Polytrim (polymyxin b and trimethoprim) is a good broad spectrum antibiotic drop and should help a bacterial infection.

Sulfates not sulfa: Polytrim (polymyxin b and trimethoprim) contains sulfates. A patient history of allergic reaction to sulfa drugs should not exclude polytrim (polymyxin b and trimethoprim) as a treatment. There seems to be no correlation between trimethoprim sulfate and sulfa sensitivity. However, one can be allergic to anything. Check with your treating doctor. ...Read more
My 18mo has pink eye, I have a prescription for polytrim that I've used before for pink eye. Can he use it as well?
Baby started first dose of Polytrim (polymyxin b and trimethoprim) on Saturday night before bed. Next 4 will be given in the morning Sunday. Can she go to daycare Monday?
Probably so: Polytrim (polymyxin b and trimethoprim) is usually prescribed to be administered 4-6 times in a 24 hour period. If you administer a dose just prior to daycare on Monday, sufficient medication has likely been given to reduce transmission to others and minimize your baby's symptoms as long as the daycare can continue the schedule during your child's time with them. Check their policy. ...Read more

Is polytrim eye drops ok for someone allergic to bactrim (sulfamethoxazole and trimethoprim) sulfa?
Depends: If you have a well documented history of an anaphylactic reaction to Bactrim (sulfamethoxazole and trimethoprim) and sulfa in the past (you could not breath and had to go to the er), it is better to choose a different eye drop as you can get a similar allergy with polytrim. In my experience, prior history of "allergy" may not be a true allergy. But tell the md who treated you to be on the same side. ...Read moreSee 2 more doctor answers
If I used polytrim (polymyxin b and trimethoprim) in eye last month and got pink eye again this month I used polytrim (polymyxin b and trimethoprim) again would that be considered prolonged use?
No: However, recurrent eye infections should make you wonder why this is happening. If you are a contact lens user, perhaps there is a problem with your lens hygiene.

Either way, allergies are on the rise. ...Read moreSee 2 more doctor answers
Nut allergy: Maybe. Your children may have inherited genes from you that make them more likely to develop an allergy, but they do not inherit a specific allergy to a food e.g. Nuts. The children have to be exposed to food proteins in the diet, before an allergy can develop. Once one develops an allergy then they are always allergic and need proper medical attention to prevent severe problems. ...Read moreSee 1 more doctor answer
