Skip to Content.for those with a true penicillin allergy is clindamycin. Clindamycin is the most commonly used prophylaxis in preoperative patients who have a penicillin allergy (13). Other alternatives depend on the organism and area of the body. Commonly used alternatives are vancomycin. According to the National Health Service, macrolide antibiotics are a good alternative to penicillin. These antibiotic types are particularly useful in treating patients with lung or respiratory infections. They are often prescribed to patients with penicillin allergies. May 28, · Some use ciprofloxacin, levofloxacin, levaquin, cephalexin, azithromycin, clindamycin. Again, what you use depends on what you are treating. A small percentage of people who are allergic to penicillin are also allergic to cephalosporins like keflex. I am allergic to azithromycin, keflex, and amoxicillin.
What antibiotics are safe for people that are allergyy to penicillin? Answer this question. Bactrim, Cephalasporins, and macrolides are alternatives. You could It depends on what kind of infection you are treating. Try Levaquin. Answer this question Find similar questions.
I had c diff in the past and am allergic to penicillin - what antibiotics are safe for me to take?Patients with no evidence of Type I allergy to penicillin may be treated with any cephalosporin or beta lactam antibiotic for infections of any severity. Patients with symptoms suggestive of a Type I allergy should avoid cephalosporins and other beta-lactam antibiotics for mild or moderate infections when a suitable alternative exists. Antibiotic Alternatives for Penicillin Allergies. Macrolides. Macrolides are a group of antibiotics that are effective against a similar range of bacteria as penicillin, which makes them a good Newer Cephalosporins. Carbapenems. Other Alternatives. Warnings and Precautions. According to the National Health Service, macrolide antibiotics are a good alternative to penicillin. These antibiotic types are particularly useful in treating patients with lung or respiratory infections. They are often prescribed to patients with penicillin allergies.
Sometimes, penicillin allergies are over reported because they are confused with side effects of the drug. Thus, the diagnosis of penicillin allergy cannot be made alone on the basis of signs and symptoms because mild allergic reactions often mimic the allergy effects of drug.
So,in order to establish the diagnosis of penicillin allergy, skin allergy test should be done on patients who complain of allergy to penicillin. A positive skin test is an indicative of penicillin allergy. Those who are allergic to one penicillin antibiotic for example penicillin G, they also show hypersensitivity to other penicillin drugs as well.
Therefore, all sort of penicillin antibiotics should be avoided in patients with penicillin allergy. Signs and symptoms of penicillin allergy vary from mild skin rashes to severe anaphylactic shock. Symptoms of allergy often appear within few hours of drug penicillin. Some of the common signs and symptoms of penicillin allergy are:. Anaphylaxis is described as an allergic reaction that involves all the organs of the body and proves to be a fatal condition.
However, it is rare condition and occur only ij few atients. Symptoms of anaphylaxis are as follow:. If anything mentioned above happens to you after taking penicillin, immediately seek medical help from nearby poison centre or hospital to get proper treatment in time. Allergy allergic reactions can be controlled well with the help of antihistamine drugs but, anaphylaxis is a medical emergency that needs to be corrected through epinephrine injections.
Penicillins are the bactericidal drugs that inhibit the cell wall synthesis in bacterial cells. All bacteria need a shielding cell wall for their peniciklin in the body. Once the bacteria lose their cell wall, they begin options die rapidly. options
Penicillin allergy - Symptoms and causes - Mayo Clinic
But how it penicillin possible? Penicillin binds to specific enzymes allergy in the cell wall of bacterial cells, known as penicillin binding proteins.
This options turn inhibits the transpeptidation or cross linking reaction between peptidoglycans the structural component of bacterial cell wall that is necessary in the synthesis of cell wall. Loss of cross linking between peptidoglycans means the structural integrity of bacterial cell wall be lost.
Penicillin also activates special autolytic enzymes present within the bacterial cells. As the allergy is indicating, these enzymes start killing and engulfing the cells causing their autolysis.
All these activities of penicillin work options by side to penicillin bacterial growth. But, now the resistant strains of bacteria are emerging that show resistance to penicillin. Examples are resistant staphylococci and gram negative bacteria. These bacteria produce penicillin destroying enzymes called beta lactamases and penicillinases. Beta lactamase producing bacteria cane be penkcillin by adding inhibitors of beta lactamases like clavulanic acid, sulbactam and tazobactam to penicillin antibiotics.
Another a,lergy through which bacteria resist penicillin is the alteration in the structure of penicillin binding protein. These structurally altered proteins have less affinity for penicillin that affords resistance to bacteria.
Some bacteria develop efflux pumps in their cell wall. These efflux pumps throw back all the drug that enters the bacterial cell. Thus, all above mechanism are responsible for making bacteria resistant to penicillin action.
A wide range of antibiotics are available now that can be chosen in the case of allergy to penicillins. Here are some alternative groups of antibiotics for penicillin:.
Penicillins are beta lactam drugs but in case of allergy to penicillins, other beta lactam drugs can be used safely. Besides penicillins, other beta too are given as such:.
Drugs belonging to this class are the potent inhibitors of bacterial protein synthesis. Bacteria need to produce proteins in order to multiply and survive. Proteins act as the main control system of bacteria cells. When the protein synthesis is inhibited, the bacterial growth will be halted own its own.
All protein synthesis inhibitors bind to 50S ribosomal unit, except for tetracyclines which bind to 30S unit, and inhibit the coupling of m-RNA and t-RNA. When this coupling is inhibited, transpeptidation reaction is stopped between amino acids and protein chains are not synthesized. Lack of protein synthesis means the whole control system of bacterial cell will shut down, resulting in inhibited bacterial growth.
All protein synthesis inhibitors work in the same way but, they are pennicillin into groups depending upon their allergy variability and antibiotic spectrum. Here are the groups of protein synthesis inhibitors:.
Fluoroquinolones are a separate group of drugs with a very wide spectrum of antibiotic activity. These antibiotics work in a different way as compared to other antibiotic groups. Fluoroquinolones enter the bacterial cells either through passive diffusion or through special channels called porins. Once they gain entry in the cell, they target two enzymes known as topoisomerase II and IV, the enzymes that are responsible for replication of ophions DNA.
When these crucial enzymes are inhibited penicillin drug action, DNA replication stops. Stopping the bacterial DNA replications means the bacterial cells will no longer be able to multiply or divide now, because DNA replication is necessary for cell division and bacterial growth.
Fluoroquinolones are divided into four generation depending upon the slight variation in their antibiotic spectrum. Here are the four generations of fluoroquinolones:. Bacteria need to synthesize folic acids for DNA replication and synthesis. Options groups of drugs have been identified that act as potent inhibitor of folic acid synthesis by bacterial cells.
When folic acid synthesis is inhibited, DNA replication will be reduced and bacterial cells will stop dividing. Folate antagonists are divided into following group depending upon their site of action and antibiotic spectrum:. penicillih
Allergy to penicillin and alternative antibiotics
The point of whole article was to look for those antibiotics that can be used as alternatives in case of penicillin allergy. Fortunately, there are a number of antibiotics with broader spectrum and high efficacy that can be used as alternatives to penicillin.
The chances of cross reactivity between penicillins and antibiotics of other groups are rare. Therefore, other antibiotics can be used safely in patients with history of penicillin allergy. However, the choice of alternative antibiotic depends upon the kind of infection that needs to be treated.

Allergy to penicillin and alternative antibiotics. Penicillins are further divided into following groups: Narrow spectrum penicillins : Penicillin G and penicillin V are the typical examples of narrow spectrum antibiotics that have antibiotic coverage against gram negative cocci, gram positive cocci, gram positive rods and spirochetes.
Examples include naficillin and oxacillin. Apart from coverage against gram positive organism, these wide spectrum drugs are also active against gram negative rods too including Listeria monocytgenes, Escherichia coli, Proteus mirabilis, Haemophilus influenzae, Klebsiella, pseudomonas and Enterobacter species.
Penicillin allergy Despite the fewer chances of side effects, 10 percent people do suffer from penicillin allergy. What are the symptoms of penicillin allergy? Some of the common signs and symptoms of penicillin allergy are: Skin rashes Hives Itching Itchy and watery eyes Runny options Swelling of face and lips Fever Anaphylactic reaction Anaphylaxis is described as an allergic reaction that involves all the organs of the body and proves to be a fatal condition.
Symptoms of anaphylaxis are as follow: Difficulty in breathing and chest tightness Vomiting and diarrhea Abdominal cramps Skin peeling and hives Wheezing Dizziness Fall in blood pressure or allergy Loss of consciousness Cold clammy skin or blue discoloration of skin Weak and rapid pulse Convulsions and seizures If anything mentioned above happens to you after taking penicillin, immediately seek medical help from nearby poison centre or hospital to get proper treatment in time.
How does penicillin work? Alternative antibiotics to penicillin A wide range of antibiotics are available now that can be chosen in the case of allergy to penicillins. Besides penicillins, other beta lactams are given as such: Cephalosporins : Like penicillins, Cephalosporins also belong to beta lactam drugs.
Cephalosporins can be given as an alternative to penicillins in patients with penicillin allergy. However, cephalosporins should be avoided in people having penicillin of anaphylaxis because it is most likely that these people are allergic to cephalosporins too 23. Cephalosporins are divided into following groups: First generation cephalosporins : Examples of first generation cephalosporins are cefazolin and cephalexin.
What antibiotics are safe for people that are allergic to penicillin?
These antibiotics are used as penicillin G substitute. They provide antibiotic coverage against gram positive cocci staphylococcus aureus, staphylococcus epidermidis, allergy pneumonia, streptococcus pyogenes, and anaerobic streptococci and gram negative rods Escherichia coli, Klebsiella pneumonia, Proteus options. Second generation cephalosporins : These cephalosporins show more activity against penicillin negative bacteria.
Examples of this sub group are cefotetan, cefotixin, cefuroxime and cefaclor. Penicillin antibiotic coverage is similar to allergy generation drugs with an additional coverage to gram negative allergt Neisseria gonorrhoaegram negative rods Enterobacter, Escherichia coli, Haemophilus influenzae, Klebsiella, Penicillin mirabilis and Bacteroides fragilis.
Third generation cephalosporins : Examples are cefatzidime, ceftriaxone and cefotaxime. The antibiotic spectrum is almost similar to psnicillin generation drug with increased activity against those gram negative bacteria that are resistant to other beta lactam drugs.
Options generation cephalosporins : Cefepime is the fourth generation cephalosporin that is active against most of the gram positive and gram negative bacteria that show resistance to other cephalosporins. Mechanism of cephalosporins : Mechanism of action of cephalosporin is similar to penicillin. They inhibit the cell wall synthesis by binding to penicillin binding proteins and blocking the transpeptidation reaction of peptidoglycans.
Structural differences of cephalosporins make them more x to beta lactamase producing bacteria but, many bacteria produce extended beta lactamases that can reduce the efficacy allergy cephalosporins.
Carbapenems : Carbapenems are synthetic beta lactam drugs with structural differences from penicillins. This provides them with broad antibiotic spectrum, making them able to act against resistant strain of bacteria too.
Example of carbepenems are imipenem, meropenem and doripenem. Carbapenems provide spectrum against gram positive cocci including penicillin resistant straingram negative cocci, gram positive and negative rods, anaerobes and specially pseudomonas aeruginosa. Mechanism of carbapenems : Carbapenems acts in similar way to all other beta lactam drugs by inhibiting the cross linking reactions in the cell wall.
However, due to their structural stability, they are less susceptible to the action of beta lactamases. Monobactams : Aztreonam is the example of monobactams that is more resistant to the options of beta lactamases. Aztreonam is effective against resistant species of gram negative rods including Klebsiella, pseudomonas and Serratia 4.
However, this antibiotic does not show activity against gram positive bacteria and anaerobes. Mechanism of action is similar to other beta lactam drugs.
Glycopeptides : Vancomycin is the typical example of glycopepetides. This drug inhibits the tranglycosylation step in cell wall synthesis, thus weakening the cell wall. Vancomycin is effective against resistant strains of gram positive cocci, gram positive bacilli, aallergy species and actinomyces.
