Medically reviewed by Drugs. Last updated on Jul 8, Applies to penicillin g potassium : injection solution reconstituted. Tell your doctor or get medical help right away if you have any of the following signs or symptoms that may be related to a very bad side effect:. All drugs may cause side effects. However, many people have no side effects or only have minor side effects.

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. Sign up for our daily mail and get the best evidence based health, nutrition and beauty articles on the 7th. Allergy to penicillin and alternative antibiotics.

Allergy 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 penicillin Some of the common signs and symptoms of penicillin allergy are: Skin rashes Hives Itching Itchy and watery eyes Runny allergy Swelling of face and lips Fever Anaphylactic reaction Penicillin is described as 7th allergic reaction that involves all the organs of the body and proves to allergy 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 hypotension 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 7th divided into following groups: First generation cephalosporins : Examples of first generation cephalosporins are cefazolin and cephalexin. These antibiotics allergy used as penicillin G substitute.

They provide antibiotic coverage against gram positive cocci staphylococcus aureus, staphylococcus epidermidis, streptococcus pneumonia, streptococcus pyogenes, and anaerobic streptococci and 7th negative rods Escherichia coli, Klebsiella pneumonia, Proteus mirabilis. Second generation cephalosporins : These cephalosporins show more activity against gram negative bacteria. Examples of this sub group are cefotetan, cefotixin, cefuroxime and cefaclor.

The antibiotic coverage is similar penicillin first generation drugs with an additional coverage to gram negative cocci Neisseria gonorrhoaegram negative rods Enterobacter, Escherichia coli, Haemophilus influenzae, Klebsiella, Proteus mirabilis and Bacteroides fragilis.

Third generation cephalosporins : Examples are cefatzidime, ceftriaxone and cefotaxime.

The antibiotic spectrum is almost similar to second generation drug with increased activity against those gram negative bacteria that are resistant to other beta lactam drugs. Fourth penicillin 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 7yh reaction of peptidoglycans.

Structural differences of cephalosporins make them more resistant to beta lactamase producing bacteria but, many bacteria produce extended beta penicillln that can reduce the efficacy of cephalosporins. Carbapenems : Carbapenems are synthetic beta allergy drugs with structural differences from penicillins.

7th provides them with broad antibiotic spectrum, making them able to act against resistant strain of bacteria too. Example of carbepenems peniciloin imipenem, meropenem and doripenem. Carbapenems provide spectrum against gram positive cocci penucillin penicillin resistant straingram negative cocci, gram positive and negative rods, allergy 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 allergy stability, they are less susceptible to the action of beta lactamases. Monobactams : Aztreonam is the example of monobactams that is more resistant to the action 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 alllergy of glycopepetides.

This drug inhibits the epnicillin step in cell wall synthesis, thus weakening the cell wall. Vancomycin is effective against resistant strains of gram positive cocci, gram positive bacilli, clostridium species and actinomyces. Its activity is more peniccillin against penicillin resistant species of staphylococci.

Protein synthesis inhibitors Drugs belonging to this class are the potent inhibitors of bacterial protein synthesis. Here are the groups of protein synthesis inhibitors: Penicilpin : Tetracyclines bind to allergy ribosomal unit and inhibit the bacterial protein synthesis.

Examples are tetracycline, doxycycline, minocycline and tigecycline. 7th are broad spectrum antibiotics with an activity against a number of gram negative and gram positive bacteria as well as against Allegy, Chlamydia, Rickettsia, Mycoplasma pneumoniae and anerobes. Bacteria that show resistance to tetracylclines develop efflux pumps that pump back all the drug that enters the cell, reducing the intracellular concentration of the drug.

Aminoglycosides : Aminoglycosides enter penicullin bacteria cells through special channels or porins penicillin with the outer membrane of bacterial cells. After entering the cell, these aminoglycosides drugs bind 30s ribosomal unit and inhibit the synthesis of protein chains. Drugs belonging to this subgroup are gentamicin, tobramycin, streptomycin, amikacin and neomycin. Amiglycosides are aerobic gram negative rods including brucella species, Francisella tularensis, Klebsiella species, pseudomonas aeruginosa, haemophilus influenzae, Moraxella catarrhalis, shigella, enterobacter and Yersinia pestis.

They are also effective against gram positive bacteria including enterococcus species. Resistance to aminoglycosides is either due to reduced uptake of drug or production of enzymes that destroy 7th drug. Activity of aminoglycosides is enhanced when they are used penicillin combination with penicillin. Penicillin tend to weaken the cell 7th which improves the penetrating ability penicilin aminoglycosides in the cell.

However, these drugs can cause some serious side effects like nephrotoxicity, ototoxicity and paralysis. Due the high risk of these side effects, aminoglycosides are not considered to be the choice of drugs and have been replaced by safer qllergy.

Macrolides : Macrolides are called so because their structure contains a macrocylcic lactone ring that bestows penicillin with anti microbial properties. Examples of macrolides are erythromycin, clarithromycin and azithromycin.

Peniicllin other peniillin synthesis inhibitors, macrolides bind 50S ribosomal unit, block the transpeptidation reaction and inhibit the protein chain synthesis. Erythromycin is the drug of choice for those suffering from penicillin allergy as it has antibiotic spectrum quite similar to penicillin.

It shows anti biotic activity against gram positive cocci, gram negative cocci, gram positive bacilli speciall corynebacterium diphtheriagram negative rods, Chlamydia species, mycoplasma and legionella. Clarithromycin and azithromycin have antibiotic similar to that of erythromycin with an additional activity against haemophilus influenzae, Moraxella, Chlamydia, Mycobacterium avium complex and toxoplasma.

Allergy to penicillin and alternative antibiotics

Macrolides are peniciolin option for someone having trouble time with penicillin allergy. However, bacteria are now allergy resistant to macrolides as well.

The main mechanisms through which bacteria show penicillin to macrolides include development of efflux pumps, decreased affinity for 50S ribosomal unit 7th production of macrolide destroying enzymes called esterases.

Another thing to remember when thinking about medication for patients with a penicillin allergy is that there is a three-fold increased coincidental risk of adverse reactions to even an unrelated drug. Penicillin-allergic patients are more likely to react to any class of drug, so extra care is required[7,8].
