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
Allergies occur when your immune system is triggered by envirionmental factors it should ignore--for example, pollen in the air, or dander on a cat or dog--and creates cells to fight against them. An allergic reaction typically causes itching, congestion, or drainage, and ...Read more
What to do if I have the infection, so is the medication called "polytrim" the correct eyedrops to use?
Polytrim (polymyxin b and trimethoprim) good: Polytrim (polymyxin b and trimethoprim) is a good broad spectrum antibiotic drop and should help a bacterial infection. Most conjunctivitis or pink eye is viral so the Polytrim (polymyxin b and trimethoprim) would help only is there is an overlying bacterial conjunctivitis which can happen. ...Read more
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
I used polytrim (polymyxin b and trimethoprim) last month for my pink eyes and I ended up getting pink eyes again this month polytrim (polymyxin b and trimethoprim) did not work is that considered prolonged use?
No: No this is not a prolonged use. Either the diagnosis is wrong or you may have a resistance. See your doctor again ...Read more
Small blisters on my lower eyelids following a diagnosis of conjunctivitis and being using polytrim (polymyxin b and trimethoprim) (5d). Is this possible or related? No other sympto
Could be possible: It could be possible related to that or could also be a different infection. I would recommend eye examination ...Read more
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. Also, this time of year allergic conjunctivitis is common and can simulate or bring on infection. Finally, be sure to clean your eyelashes and lids daily with a washcloth and warm water. ...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 more

Exposure + Genes: One needs both a genetic component and "exposure" to a said allergen to develop an allergy. There is a growing support over the past 20 years, that growing up in an environment which is "too clean" can also lead to development of allergies down the road. Either way, allergies are on the rise. ...Read more
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 more
Allergy tests: There are several types of testing. Some involve certain types of blood tests. Another method is to do a series of skin tests done by pricking the skin and applying different allergens. Other tests are provocative tests that can involve challanging the patient with allergic materials. Testing should be done by doctors specializing in allergy to obtain the best results. ...Read more
Skin & blood tests: Prick testing with allergenic extracts or fresh foods can help confirm allergy, as can blood tests for specific ige antibodies (rast-type tests). However, both types of testing can produce false positive results, and confirmation with food challenges may be needed. ...Read more
Not exactly: The ability to react to certain proteins in an allergic way is passed on from parents to their children, but a specific allergy is not. So if a mom is allergic to pollen and the dad is allergic to fire ants, their child may develop allergies but it may be to a food instead. If 1 parent has allergies, the child is 50% likely to develop allergies, but it's a 75% chance if both parents are allergic. ...Read more

Where can I find a statistic for the number of children who died from allergies causing anaphylaxis in the u.S.?
Only overall numbers: The incidence of anaphylaxis in children is unknown. Estimates of anaphylactic deaths (from drugs, foods, insect stings, and latex) in the us are 0.002 percent annually (2 per 100, 000): 500 fatalities from penicillin anaphylaxis; 40 fatalities from bee stings; 125-150 from food anaphylaxis. ...Read more
My husband has nut and fish allergies. I have 4 children, 2 without allergies should I get rest of kids tested before giving them these foods?
I give my 17mnth old 1/2 teaspoon of children's zyrtec (cetirizine) for allergies but some days it's not enough. Can i increase the dose or try something differ t?
Do not increase : A 17 month old should not have allergies to inhaled items like dust or pollen. Zyrtec (cetirizine) could cause drowsiness and i would avoid long term use of zyrtec (cetirizine) in your child. If your child has a runny or stuffy nose that is unresponsive to zyrtec (cetirizine) then see your doctor to make sure there isn't an infection brewing. ...Read more
Yes: Not all of the food allergies are created equal. Food allergies like dairy, egg, wheat tend to be outgrown. Tree nut and peanut are less likely (although recent studies suggest that 20-30% outgrow the peanut allergy). Environmental allergies tend to "grow on you" with time. Note: the allergy test may remain positive despite the child having outgrown the allergy. Consult with an allergist. ...Read more
It depends: It really depends on the age of the child, and whether you're talking about food or environmental allergies. I generally will skin test children over age 2 for environmental allergies, while many younger kids need food testing. In terms of frequency, children with environmental allergies may benefit from repeat testing after 2 years, as their allergies can change as they get older. ...Read more
Hygiene hypothesis: The immune system has two opposing arms, one makes protective antibodies against bacteria and viruses, the other makes allergic antibody. One theory is that early antibiotic use disrupts the gut flora which tips the scale away from fighting infection and more toward making allergic antibodies. Clean environments might be at fault as well, farm kids don't get allergies as much as city kids. ...Read more
