Colonic Reactions To Kefles
Colitis (sigmoid) adverse reaction to Cipro (ciprofloxacin) and/or Flagyl, are there alternative courses of treatment that maybe aren't so harsh?
Can a severe allergic skin reaction including: dermatitis, hives, eodema, erythmaderma cause new sensitivities to other chemicals to begin?
Yes: Statistically the penicillin family of antibiotics trigger the most reactions because they are so universally used. Penicillin testing is widely available by allergists and is recommended to avoid needlessly avoiding this inexpensive and effective family of antibiotics. But any kind of antibiotic carries with it the chance of allergy, and as a class, is one of the most common drug causing allergy. ...Read moreSee 1 more doctor answer
Can food intolerances become life threatening? Can food intolerances become allergic reactions with continued exposure?
Is doxycycline well tolerated, & is it one of the antiobios more likely to cause allergic reactions? I'm allergic to keflex and nervous to take doxy.
Doxycycline: Doxycycline can sometimes cause stomach upset, and this can potentially limit its use. This side effect is not an allergy, however. People who are allergic to Keflex (generic cephalexin) may need to avoid other so-called beta-lactam antibiotics, which include the penicillins and cephalosporins. An allergy to Keflex would not predispose you to an allergy to Doxycycline as they are not related. ...Read moreSee 1 more doctor answer
Yes: Allergy to the entire class of antibiotics called cephalosporins is indeed possible. That allergy would be the common part of the molecule shared by all cephalosporins and penicillins, the beta-lactam ring. ...Read more
Would the older or newer generation of cephalosporins antibiotics be more likely to cause anaphylaxis in patients severely allergic to penicillin?
See below: Persons with type 1 immediate hypersensity to penicillin antibiotics should generally avoid taking cephalosporin antibiotics because of the low but real risk of cross allergenicity. Safe alternative antibiotics include vancomycin, septra, (sulfamethoxazole and trimethoprim) macrolides, tetracyclines, aztreonam, clindamycin, zyvox, quinolones etc. ...Read moreSee 2 more doctor answers
Yes/unrelated: People that are allergic to penicillin can be allergic to "fruit mold" but they are completely different reactions and are unrelated. The "fruit mold" that you are mentioning is probably pennicilium - the mold that actually makes penicillin. However, allergic reactions to those are separate and unrelated. ...Read more
Have ulcerative colitis in sigmoid and ascending colon/cecum (just confirmed by colonoscopy). Will enema treat this (allergic to NSAIDs)?
Consider allergy ref: Thanks for your question. Depending on the NSAID allergy, sometimes it can be desensitized through introduction of small amounts initially, then gradual increase in dose under supervision by an allergy specialist. However, would discuss the side effects/risks/benefits with a specialist. ...Read more
If the oral allergy syndrome is due to x-reactions between homologous proteins in ingested food and aero-allergens why aren't food skin tests +?
Too complex...?!: The gut is both an immune privileged site and responds adversely (and often unpredictably) to ingested materials (e.g. Bacteria, food, dirt, etc.). There may be too many variables to easily answer your question. A case in point is eosinophilic esophagitis. Sadly, given our knowledge gap, too many patients take too many supplements or exclude too many products for questionable reasons. ...Read moreSee 2 more doctor answers
Yes: There are a number of effective antibiotics that your doctor can choose. Most patients who think that they are allergic to penicillin are not. Even patients who had a reaction in the past usually lose the allergy. An allergist can test to see if you are allergic. ...Read moreSee 1 more doctor answer
How do you treat strep throat if I'm allergic to bactrim, keflex, cipro, (ciprofloxacin) and amoxicillin? Also allergic to inactive ingredient propylene glycol.
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
