Is strep susceptible to cefdinir?
2 Answers. Omnicef and Ceftin are similar drugs (of the antibiotic variety), but they are not exactly the same. In fact, people who have allergic reactions to one of these antibiotics will often try the other instead.
Call Your Doctor If: Fever lasts more than 2 days after starting antibiotics. Sore throat lasts more than 3 days after starting antibiotics. You think your child needs to be seen. Your child becomes worse.
Cefdinir is effective against susceptible bacteria causing infections of the middle ear (otitis media), tonsils (tonsillitis), throat (strep throat), larynx (laryngitis), sinuses (sinusitis), bronchi (bronchitis), lungs (pneumonia), and skin and other soft tissues.
Cefdinir (Omnicef) is an oral third-generation cephalosporin with good in vitro activity against many pathogens commonly causative in community-acquired infections.
Doctors treat strep throat with antibiotics. Either penicillin or amoxicillin are recommended as a first choice for people who are not allergic to penicillin. Doctors can use other antibiotics to treat strep throat in people who are allergic to penicillin.
Cefdinir and amoxicillin are most effective when they are targeting susceptible bacteria. If they are used inappropriately, the bacteria can gain antibiotic resistance and cause a more severe infection.
No interactions were found between amoxicillin and Omnicef. This does not necessarily mean no interactions exist. Always consult your healthcare provider.
Omnicef and Augmentin are different types of antibiotics. Omnicef is a cephalosporin antibiotic and Augmentin is a combination of a penicillin-type antibiotic and a beta-lactamase inhibitor. The brand name Omnicef is discontinued in the U.S. Generic versions of cefdinir are available.
Cefdinir will start working right away to fight the infection in your body. You should start to feel better after 2 days, but continue to take the full course of your medication even if you feel like you don’t need it anymore.
Results: Cefdinir has a broad spectrum of activity against many gram-negative and gram-positive aerobic organisms, including Streptococcus pneumoniae, Staphylococcus aureus, Streptococcus pyogenes, Haemophilus influenzae, and Moraxella catarrhalis. Cefdinir is stable to hydrolysis by 13 of the common beta-lactamases.
This antibiotic treats only bacterial infections. It will not work for viral infections (such as common cold, flu).
Beta-Hemolytic streptococci was highly susceptible to cefdinir (MIC(90), < or =0.03-0.06 microg/mL), while viridans group streptococci showed slightly elevated MIC results.
