Allergic To Erythromycin For Std
I have a Duodenal ulcer and positive for H.Pylori. Allergic to Penicillin erythromycin cephalosporin diclofenac. What antibiotic is available to take?
See allergist: I would also suggest seeing an allergist to evaluate you and determine if your allergies are true. It is very unusual to be allergic to so many different medications. And many times, patients grow out of medication allergies even if they were true in the past. ...Read moreSee 1 more doctor answer
This is a disease which can be transmitted from one person to another person through sexually related activities. This does not limit these activities to heterosexual intercourse, but encompasses all modalities of human-to-human sexual activity. It does not include illnesses that may make an individual more susceptible to a condition because of a sexual ...Read more
Some of them: Their are different "classes", or families of antibiotics. You would be likely to have a reaction to amoxicillin, for instance. Their is some cross reactivity with cephalosporins, like keflex, in approximately 15% of people. You could be allergic to other meds as well, but would not be much more likely than the general population to have an allergy to quinolones, like cipro, (ciprofloxacin) or macrolides. ...Read moreSee 1 more doctor answer
I have a skin infection and need an antibiotic but allergic to penicillin? What antibiotic is good?
Depends: It would depend on the type of penicillin allergy you had and the type of skin infection. If you just had a rash from penicillin and you do not have an MRSA infection cephalosporins like Keflex would be fine. If immediate hypersensitivity to penicillin, clindamycin, Doxycycline or septra (sulfamethoxazole and trimethoprim) would be options. ...Read more

Can levofloxin be used to treat a strep throat infection? Are there better choices? I am allergic to penicillin and tetracylinces.
Yes: It is known that 60-70% of those thought penicillin allergic are not, skin testing in a protected setting can usually provide more accurate status. Nontheless, the drug Doxycycline given over a 2 wk period may cure syphillis, Azithromycin has been used but some resistant strains have been found. Penicillin is the only drug known effective during pregnancy & can be used with rapid desensitization. ...Read moreSee 1 more doctor answer
Not allergic to cipro, (ciprofloxacin) but allergic to avelox and levaquin does this make sense?What to take for prostate? Allergic to bactrim ad well.
Unusual: Since they are all in the quinolone class , it is surprising. On the other hand, each drug has its own chemical structure and thus it is possible that you are not reacting to one of the group. In general, if I get a history of a reaction to two drugs in the same class, I will select an alternate. ...Read moreSee 1 more doctor answer
No cross reaction: Ampicillin and other penicillin-type antibiotics have a completely different chemical structure than erythromycin. Thus, the risk for allergic reaction to Ampicillin is no different than your average person. Your doctor can tell you which antibiotic (ampicillin, cipro, (ciprofloxacin) etc.) will be most effective for a given infection (sinus infection vs skin infection, etc.). See your doctor for more info. ...Read more
Need to take Macrobid for UTI. I'm allergic to so many meds (hives); is Macrobid likely to cause reactions? My only antiobio alrgy is Keflex.
Avoidance: If one is allergic to penicillin then avoidance of penicillin like medications is a requirement. Other classes of antibiotics should be fine but because an individual has one drug allergy they may be at risk for reactions to other classes of drugs. One should also be very clear that moving forward that antibiotics are needed. ...Read more
Can I use doxycycline for diverticulitis? Allergic to sulfa and penicillin and unable to tolerate cipro/flagyl. Have not tried doxycycline.
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
