Can I Take Bactrim If Allergic To Amoxicillin
Not same class: Someone allergic to amoxicillin (in penicillin class) is not considered at high risk for clindamycin allergy (not penicillin class). That does not guarantee that there will not be any reaction. When taking clindamycin, it is a good idea to eat yoghurt or take probiotics to prevent c. dif colitis (a bacterial infection of the colon due to the selective killing of beneficial bacteria). ...Read moreSee 1 more doctor answer
Maybe: You have about a 2-5% chance to also be allergic to cefuroxime. You may want to talk to your allergist about testing to penicillin first to confirm this allergy. If you do have pcn allergy, then you can: 1.Use a different antibiotic 2. Do a graded challenge/desensitization to cefuroxime. If negative to pcn on testing, <1% will have problems with cefuroxime. ...Read more
probably: First of all, how do you know you are allergic to augmentin (amoxicillin and clavulanate)? The medication is actually 2 drugs (amomxicillin+clavulanic acid) and can cause rashes that are not due to allergy. Most patients who develop a rash with Amoxicillin can tolerate cephalexin. To be on th esafe side, see an allergist/immunologist. ...Read more
Yes: From the standpoint of cross-allergy there is none. Two questions. What is the allergic reaction to pcn? (are you truly allergic). And then, since patients prone to true allergic reactions have a great chance of reacting to sulfonamides (like in bactrim), not because of cross-hypersensitivity, but because sulfa drugs have high frequency of allergic reactions. Discuss this with your doctor. ...Read more
Likely, not certain: The majority of people who are told they are allergic to penicillin are not actually so (they get rashes for other reasons, e.g.). Of those that are allergic, about 70% or more will lose the allergy after about 10 years. If you are still allergic, there is about a 10% chance of cross-reaction to 1st-gen cephalosporins like keflex. An allergist can perform testing to judge your risk for a reaction. ...Read more
Not likely: Just because you have an allergy to Bactrim doesn't put you at increased risk for developing an allergy to cipro (ciprofloxacin). There are lots of options for antibiotics that don't cross-react with sulfa drugs so you should be fine. If you want to understand your drug allergy in more detail see a board certified Allergist for further workup and evaluation. ...Read more
No: Augmentin (amoxicillin and clavulanate) is a combination of Amoxicillin and clavulinic acid. If you are allergic to augmentin (amoxicillin and clavulanate), (amoxicillin and clavulanate) it most likely means you have an allergy to penicillin. Your physician will know this and prescribe another non-related antibiotic. Do not take penicillin if you are certain you are allergic to augmentin (amoxicillin and clavulanate). ...Read more
Can I take augmentin (amoxicillin and clavulanate) if I'm pregnant and allergic to cephalosporins but not amoxicillan?
Yes,: No problem taking Augmentin (amoxicillin and clavulanate) while pregnant, as for the cross-reactivity: usually it's the other way round, people who are allergic to penicillin/amoxicillin (component of Augmentin (amoxicillin and clavulanate)) ask if they can administer cephalosporins. At any rate, tell your doctor, and if any doubt, take the first dose in the doctor's office or ER waiting area, stay for an hour, if nothing happens, leave, good luck ...Read more
Can you tell me what to do if i took augmentin (amoxicillin and clavulanate) and i'm allergic to pinicillin?
See your doctor: Vast majority of people that were told they are allergic to penicillin (PCN) are really not. Most true allergies to PCN resolve after 10 years or so. Likely you will be fine. But, you should follow up with your doctor to make sure. Also, an allergist can verify PCN allergy by special testing. If you develop trouble breathing, hives, or vomiting, call 911 and get seen right away. ...Read more
Yes: I have been using Ceftin (cefuroxime axetil) in penicillin allergic patients for years without any problem. You can safely take ceftin. Other antibiotics that can be used are the fluoroquinolones such as Ciprofloxacin or levaquin (levofloxacin). The latter is more expensive but has a very low rate of bacterial resistance. ...Read more
What to do if I have strept throat, and im allergic to penicillin, can take amoxicillin or keflex instead?
No : Amoxicillin is within penicillin class and the risk of having a reaction is significant so it should be avoided. There is controversy about the risk of cross reaction between class of antibiotics penicillin and cephalosporin (keflex). It appears the risk is low (but not 0). If penicillin allergy was years ago, skin testing for penicillin can help know if it is still there. Allergist can help. ...Read more
