Omnicef vs Augmentin
Introduction
For patients with various types of bacterial infections, certain antibiotics can help in eliminating the infection and managing symptoms. Omnicef (cefdinir) and Augmentin (amoxicillin/clavulanate) are two such drugs that are often prescribed for bacterial infections. They each inhibit different stages of cell wall synthesis in bacteria, but both have bactericidal effects on a wide range of pathogens. Omnicef is a third-generation cephalosporin that works by binding to penicillin-binding proteins within the bacterial cell wall leading to death of the bacteria. On the other hand, Augmentin is a combination medication consisting of amoxicillin, which interferes with cross-linking peptide chains during cell wall biosynthesis, and clavulanate potassium- a beta-lactamase inhibitor which prevents resistance by blocking enzyme pathways.

What is Omnicef?
Cefdinir (the generic name for Omnicef) is a third-generation cephalosporin antibiotic that marked a significant advancement from the first class of antibiotics known as penicillins. Cefdinir was first approved by the FDA in 1997 and acts by inhibiting the synthesis of bacterial cell walls, effectively stunting their growth in your body. It is prescribed for treating various forms of bacterial infections, such as sinusitis, pneumonia, ear infections, bronchitis, skin infections and tonsillitis. On the other hand, Augmentin is a combination drug that includes amoxicillin (a penicillin derivative) and clavulanate potassium which act together to fight against bacteria resistant to traditional penicillin drugs. While both are effective at treating similar types of infections caused by susceptible bacteria strains, they differ in potential side effects; with Omnicef potentially causing milder gastrointestinal disturbances compared to Augmentin due to its more targeted action on specific classes of bacteria.
What conditions is Omnicef approved to treat?
Omnicef is approved for the treatment of various bacterial infections such as:
- Acute bacterial otitis media, also known as ear infection
- Pharyngitis and tonsillitis, commonly known as throat infections
- Acute maxillary sinusitis, a type of sinus infection
- Pneumonia
- Bronchitis
- Skin and skin structure infections.
Meanwhile, Augmentin is also used to treat similar conditions but has an extended scope which includes urinary tract infections (UTIs), lower respiratory tract infections, and certain types of skin infections.
How does Omnicef help with these illnesses?
Omnicef, also known as cefdinir, is a broad-spectrum antibiotic used to treat various types of bacterial infections. It does this by inhibiting the synthesis of peptidoglycan, an essential component for bacterial cell walls. By doing so, Omnicef weakens the bacteria's structural integrity and eventually causes them to burst open and die. The dying bacteria are then cleared out by your immune system.
Augmentin (a combination of amoxicillin and clavulanate) works similarly in battling bacterial infections but with an added advantage; it contains clavulanate which inhibits beta-lactamase—an enzyme that some resistant bacteria produce to fend off antibiotics like amoxicillin. This makes Augmentin particularly effective against antibiotic-resistant strains.
Both medications have their unique strengths: Omnicef requires less frequent dosing while Augmentin can target drug-resistant bugs more effectively. As such, each may be preferable depending on the specific nature of the infection and patient factors.
What is Augmentin?
Augmentin is a brand name for the combination of amoxicillin and clavulanic acid, two active ingredients that work together to enhance effectiveness against a broad range of bacteria. This drug belongs to the penicillin group of antibiotics and works by blocking the bacterial cell wall synthesis, leading to cell death. Augmentin was first approved by the FDA in 1984.
As Augmentin contains clavulanic acid, it has an extended spectrum compared with amoxicillin alone which can be beneficial in treating certain infections resistant to other antibiotics. Its dual action means that its side-effect profile may vary from those seen with drugs such as Omnicef (a cephalosporin antibiotic). In particular, common side effects include diarrhea or loose stools, nausea, skin rashes or urticaria (hives), and vaginal yeast infections. It's often prescribed when patients do not respond well to "typical" antibiotics like Omnicef.
What conditions is Augmentin approved to treat?
Augmentin is a broad-spectrum antibiotic that has been approved for treating the following bacterial infections:
- Sinusitis and pneumonia
- Middle ear infections (Otitis media)
- Skin and soft tissue infections
- Urinary tract infections It's important to note that Augmentin, like all antibiotics, should only be used to treat bacterial—not viral—infections.
How does Augmentin help with these illnesses?
Augmentin, a combination of amoxicillin and clavulanate, is an antibiotic that works by disrupting the bacterial cell wall formation, thereby leading to bacterial death. Amoxicillin attacks the main structure of the bacteria while clavulanate helps prevent resistance mechanisms employed by certain bacteria. This dual action makes Augmentin particularly effective in treating a wide range of infections including those resistant to antibiotics similar to Omnicef. Like norepinephrine, these antibiotics are integral components that serve crucial roles in maintaining health - they combat harmful pathogens instead of regulating neurotransmitters or hormones. In instances where Omnicef (cefdinir), a third-generation cephalosporin antibiotic might not be working effectively on its own due to bacterial resistance or allergic reactions in patients, Augmentin may be prescribed as it covers a broader spectrum of bacteria.
How effective are both Omnicef and Augmentin?
Both cefdinir (Omnicef) and amoxicillin/clavulanate (Augmentin) are well-established antibiotics for treating a variety of bacterial infections, and they were initially approved by the FDA within a decade of each other. As they belong to different classes of antibiotics - cephalosporins for Omnicef and penicillins for Augmentin - they may be prescribed under different circumstances based on the specific bacteria causing the infection.
Several studies have directly compared cefdinir to amoxicillin/clavulanate in terms of their ability to treat various infections such as sinusitis, bronchitis, or pneumonia. Generally speaking, these two drugs exhibited similar efficacy in managing symptoms and clearing up infections with comparable safety profiles. In many studies, no significant differences were found between patients receiving Omnicef or those receiving Augmentin in terms of clinical success rates.
A 2000 review showed that cefdinir is effective from its initial use at fighting off common bacterial strains causing upper respiratory tract infections while maintaining an impressive side effect profile compared to other antibiotics. Furthermore, it was demonstrated that cefdinir has become one of the top-prescribed cephalosporin-class antibiotics due to its broad spectrum coverage against both gram-positive and gram-negative pathogens.
Meanwhile, a 2018 meta-analysis indicated that amoxicillin/clavulanate continues to provide excellent antimicrobial activity against major pathogens responsible for community-acquired respiratory tract infections; however it does come with some potential gastrointestinal side effects like diarrhea. Despite this minor drawback commonly associated with most oral antibiotic therapies including Augmentin itself; when considering effectiveness coupled with resistance patterns among key respiratory pathogens – Amoxicillin/Clavulanic Acid remains superior as first-line treatment option against common bacterium.

At what dose is Omnicef typically prescribed?
Oral dosages of Omnicef range from 7-14 mg/kg/day, divided into two doses for children under the age of 12. For adults and adolescents, the typical dosage is 300 mg twice daily or up to 600 mg once daily. Studies have indicated that these doses are typically sufficient for treating bacterial infections in most people. However, depending on the severity and type of infection, your healthcare provider may adjust your dosage accordingly after a few days if there is no improvement. The maximum dose should be carefully determined by your health professional but generally should not exceed 600mg per day.
At what dose is Augmentin typically prescribed?
Augmentin treatment typically begins with a dosage of 250 mg to 500 mg every 8 hours, or 875 mg every 12 hours for more severe infections. The dose can then be increased if necessary, based on the severity and type of infection. For certain conditions like respiratory tract infections, sinusitis or skin infections; it could go up to as high as 2000mg/day divided into two doses spaced at least 12 hours apart. It's important not to exceed the maximum recommended daily dose unless under strict medical supervision and always remember that responses may vary depending upon individual patient characteristics.

- Unusual tiredness could be indicative of kidney problems If you experience any of these symptoms while taking Augmentin, contact your healthcare provider immediately.
Contraindications for Omnicef and Augmentin?
Both Omnicef (cefdinir) and Augmentin (amoxicillin/clavulanate) are antibiotics that can lead to a range of side effects in some individuals. If you experience severe diarrhea, intense stomach cramps, or blood/mucus in your stool after taking these medications, it is crucial to seek immediate medical attention.
Neither Omnicef nor Augmentin should be taken if you have a history of severe allergic reactions to other antibiotics. Always inform your physician about all the medications you're currently using; this includes any over-the-counter drugs, vitamins or herbal supplements as well.
In case you've been diagnosed with kidney disease or intestinal problems like colitis, special caution is necessary when considering these antibiotics. It's also important for pregnant women or those planning to conceive to consult their healthcare provider before starting on either medication due to potential risks during pregnancy and breastfeeding.
How much do Omnicef and Augmentin cost?
For the brand name versions of these drugs:
- The price of 20 capsules of Omnicef (300 mg) averages around $500, which works out to about $25/day, depending on your dose.
- The price for 20 tablets of Augmentin (875-125 mg) is approximately $400, working out to roughly $20/day.
Thus, if you are in the higher dosage range for Omnicef (i.e., 600 mg/day or higher), then brand-name Augmentin can be less expensive on a per-day treatment basis. Remember that cost should not be the primary consideration when determining which drug is best suited for you.
As far as generic versions go:
- Cefdinir (generic version of Omnicef) can be found in packs ranging from 10 up to several hundred capsules with prices varying between $0.60 and over $2 per day based on dosages reaching up to 600mg daily.
- Amoxicillin/clavulanate potassium (the active ingredients in Augmentin) usually comes in packages starting at ten tablets and going upwards. Costs may start as low as just under a dollar per day but could also exceed three dollars daily depending upon dosage levels and where it's purchased.
Popularity of Omnicef and Augmentin
Cefdinir, widely known by its brand name Omnicef, is an antibiotic commonly used to treat different types of bacterial infections. In 2020, it was estimated that about 5 million prescriptions were filled for cefdinir in the US. This accounted for nearly 18% of prescriptions in the cephalosporin class of antibiotics.
Conversely, Augmentin (a combination of amoxicillin and clavulanate) was prescribed to approximately 20 million people in the USA in the same year. Augmentin accounts for just over a quarter of all penicillin-class antibiotic prescriptions, and around one tenth overall within broad-spectrum antibiotics category.
The prevalence of both Omnicef and Augmentin has been relatively stable over the past decade. However, physicians may prefer prescribing Augmentin due to its wider coverage against bacteria resistant to amoxicillin alone thanks to clavulanic acid's inhibition of beta-lactamase enzyme.
Conclusion
Both Omnicef (cefdinir) and Augmentin (amoxicillin/clavulanate) are broad-spectrum antibiotics used to treat a variety of bacterial infections. They have a solid track record backed by significant clinical research, providing evidence that they are effective in treating infections more successfully than placebo treatments. Due to their different mechanisms of action, with Omnicef primarily acting as a cephalosporin antibiotic and Augmentin being an amalgamation of penicillin antibiotic and beta-lactamase inhibitor, they tend to be prescribed under varying circumstances.
Omnicef is often preferred for its once-daily dosing convenience compared to the multiple daily doses required for Augmentin. However, both drugs are available in generic form which can lead to considerable cost savings especially for patients who must pay out-of-pocket.
An adjustment period may be needed when starting these medications as it takes time for them to exert their full effects on bacterial colonies within the body.
The side effect profile is similar between the two drugs; however, gastrointestinal disturbances like diarrhea or nausea seem less common with Omnicef than with Augmentin. Both antibiotics require careful monitoring from healthcare professionals due to potential adverse reactions such as allergic responses or Clostridium difficile-associated diarrhea (CDAD). It's crucial that anytime you start new medication including these antibiotics, any unusual symptoms should prompt immediate consultation with your healthcare provider.
