Sulfa drugs- rash can I use polymyxin b sulfate eye drops?
Yes: Polymyxin is an effective anti-bacterial. You could use it without the allergies popping up as it has with others. However: are you sure you need this drop? It seems as if you are using an antibiotic for every eye inflammation, most of which are probably not bacterial. And in so doing you have sensitized yourself to antibiotics that you might need for an actual infection. ...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
Maybe: Penicillin allergy is usually secondary to either the beta-lactam components or the minor determinants. If you are found to be allergic (via skin testing) to the beta-lactam component then you are at risk for sensitization to all beta-lactam medications, including cephalosporins. Fortunately in the majority of people, this is not the case. You should consult with your local allergy specialist. ...Read moreSee 1 more doctor answer
Cephalosporin rx: Older studies suggested that there was a 5-7% risk of having a reaction to a cephalosporin if you had a history of penicillin allergy. However, there have been recent studies indicating that the newer cephalosporins are structurally different enough that the risk of cross reaction is quite low, even eliminating the need to test for penicillin allergy prior to administering the cephalosporin. ...Read moreSee 1 more doctor answer
Can I take an otc antihistamine along with bactrim (sulfamethoxazole and trimethoprim) and prednisone? It is not for allergic reaction from bactrim (sulfamethoxazole and trimethoprim), just for pollen allergy
Yes: However, you may find that the prednisone (assuming you're using it for something else) helps more for the pollen allergy than antihistamine. If you are receiving treatment for chronic or worsening sinus pressure/infection, then I strongly recommend seeing an Allergist to get help in the future. Recurrent sinus infections will persist unless the allergy is addressed properly. Good luck! ...Read moreSee 1 more doctor answer
Does Bactrim (sulfamethoxazole and trimethoprim) have sulfa. I am allergic to sulfa? Which one is better for UTI Keflex or Bactrim (sulfamethoxazole and trimethoprim)
Bactrim (sulfamethoxazole and trimethoprim) is sulfa: Bactrim (sulfamethoxazole and trimethoprim) contains a sulfonamide ("sulfa drug") called sulfamethoxazole. It needs to be avoided by people with sulfa allergy. Cephalexin (Keflex) is less reliable for UTI; many UTI bacteria are resistant to it. Ask your doctor about possible treatment with a quinolone like ciprofloxacin, levofloxacin, and others. ...Read more
I am allergic to penicillin G per the blood test. Augmentin (amoxicillin and clavulanate) caused the reaction. Is Augmentin (amoxicillin and clavulanate) , penicillin "G" ? Ty
Similar: The amoxicillin in Augmentin (amoxicillin and clavulanate) and Penicillin share a common core structure and thus people allergic to Penicillin are almost always allergic to amoxicillin. On the other hand, not all people reacting to amoxicillin are allergic to penicillin when the reaction is a skin rash. ...Read more
Im allergic to penicillin and erythromycine, can I take bactrim (sulfamethoxazole and trimethoprim)?
Yes but for what?: Yes. You can take Bactrim (sulfamethoxazole and trimethoprim) as it is a sulfa drug and different class of drug from penicillin and erythromycin. The real question is for what condition do you want to take? Because the causative organisms for specific diseases may be virus, bacteria, fungus or parasite and the Bactrim (sulfamethoxazole and trimethoprim) is not a magic bullet for all. See your doctorwho would tailor the antibiotic according to organism & sensitivity. ...Read moreSee 1 more doctor answer

There are none: If you are truly allergic to sulfa you must avoid all forms of the drug whether it be in eye drops, pills or IV meds. There is no med to cancel out the allergy and true allergy could lead to life threatening consequences if exposed. It would be wise to invest in a medical alert bracelet to make sure people are aware if you cannot communicate. ...Read moreSee 1 more doctor answer
Check the labels: Also only use high quality pharmaceutical grade supplements and neutraceuticals, as the cheap stuff is from asian countries that don't have FDA oversight. Also, note that celebrex (celecoxib) has a sulfa molecule component and there is cross allergenicity between it and all other sulfa agents that produce allergic reactions. ...Read more

Sulfa, cosopt: Depending on what your target range of pressure is, you could try timolol, alphagan, xalatan, (latanoprost) lumigan, travatan, xioptan, or combigan. Pilocarpine is also available but not nearly as convenient to use. Then there is laser treatment too. Incisional surgery for glaucoma would be for people whose eye pressure is suboptimally controlled despite maximal tolerated medical &/or laser treatment. ...Read more
