It belongs to the third generation of cephalosporin antibiotics and was approved by the FDA in 1997. Omnicef is effective against bacteria that are resistant to other types of antibiotics due to their production of beta-lactamase enzymes.

Effectiveness

How Omnicef Affects Patients

Cefdinir is a type of medicine that kills bacteria and prevents them from multiplying. It is effective against a wide range of gram-positive and gram-negative bacteria, including those that are resistant to other cephalosporins. Cefdinir works by stopping the bacteria from building their cell walls, which helps to stop them from spreading.

How Omnicef works in the body

Cefdinir attacks bacteria in a similar way to other beta-lactam antibiotics. It works by binding to proteins that help form the bacterial cell wall. By doing this, it interferes with the cell wall's formation, which leads to cell death. Cefdinir has a stronger effect than penicillin because it has a 6-member dihydrothiazine ring instead of the 5-member thiazolidine ring found in penicillin. This 6-member ring helps the drug resist inactivation by certain bacterial enzymes and binds to penicillin-binding proteins. In addition, cefdinir

My two year old daughter was diagnosed with a sinus infection and double ear infection and was put on cefdinir to treat these issues. After being on the medication for 5 days she started swelling all over and breaking out in a rash/hives. A trip to the ER told us she having an allergic reaction to the medication.

I was prescribed this for a UTI and, while it did clear up the infection after five days, I am now retaining urine and unable to urinate. On a catheter for a week to see if this gets resolved. Will not take this drug again; its listed side effects include decreased or inability to urinate.

My daughter had a double ear infection and was prescribed this medication. However, after 10 days of taking the medicine, she broke out in a rash with hives all over her body.

Omnicef for Strep Throat

My son is 13 and has taken this many times before with no problems. This time for strep,all was good till he finished the last dose. Slowly he started itching, which progressed to huge swollen hives and a sunburn looking rash on his head, legs, arms. It kept moving from place to place but stayed on his head. Also had painful joints. Now on Benadryl and steroids. I was relieved to find these reviews because it seems like others have had the same experience.

Omnicef for Middle Ear Infection

My one year old daughter was given this medicine after Amoxicillin failed to treat her double ear infection. However, after only four days of taking the medication, she broke out in a terrible rash that covered her entire body. We took her to urgent care, but they simply told us to wait until Monday morning to see her regular doctor. In the meantime, she looks like she has a sunburn all over and is clearly very uncomfortable. Does anybody have any suggestions for how I can help ease her discomfort?

Omnicef for Acute Maxillary Sinus M. Catarrhalis Bacteria Infection

I had an acute sinus infection and took Omnicef. However, after just two days of taking the medication, my Crohn's Disease (which had been in remission) suddenly became very active again. This antibiotic kills the normal bacteria in the bowel and causes big problems. I will never take this medication again; it is dangerous!

Omnicef for Strep Throat and Tonsillitis

I think the company that now manufactures this drug has changed the recipe or something, because I took it a few years ago with no side effects whatsoever. This time, though, I developed new side effects every day until I had terrible diarrhea and had to stop taking the drug. F*** that drug company!

What is Omnicef used to treat?

"It will not work for viral infections (such as common cold, flu).

Cefdinir is used to treat a wide variety of bacterial infections by stopping the growth of bacteria. This antibiotic only treats bacterial infections and will not work for viral infections such as the common cold or flu."

Answered by AI

Why was Omnicef discontinued?

"About 0.4% of patients had to stop taking cefdinir because they developed gastrointestinal problems like diarrhea or nausea. 19 out of 5093 patients developed a rash that was possibly caused by the medication."

Answered by AI

Is Omnicef a strong antibiotic?

"Cefdinir is an effective antibiotic against a wide range of bacteria. However, there are other antibiotics that can treat more types of infections, or more serious infections."

Answered by AI

Is Omnicef the same as amoxicillin?

"Are Omicef and Amoxicillin drugs that treat similar infections? Omnicef (cefdinir) is a cephalosporin antibiotic and amoxicillin is a penicillin-type antibiotic. They are both drugs that are used to treat infections, but they are in different drug classes."

Antibiotic Strategies for Pneumonia in Children

12 - 71
All Sexes
Atlanta, GA

The goal of this clinical trial is to determine if a "watch and wait" antibiotic strategy, called Safety Net Antibiotic Prescribing (SNAP), can safely reduce unnecessary antibiotic use while ensuring that children diagnosed with community-acquired pneumonia get better from their illness. The main aims of this study are: * To compare the effectiveness of SNAP versus immediate antibiotic prescribing in children with mild community-acquired pneumonia (CAP) * To identify which patient groups benefit most from the SNAP strategy * To identify factors that shape implementation of each prescribing strategy. Researchers will compare the SNAP strategy (where parents or guardians are instructed to give antibiotics only if their child is not improving after 72 hours, or sooner if they are worsening) to the immediate antibiotic prescribing strategy (where parents or guardians are instructed to give the antibiotics right after their healthcare visit) to see if one strategy is more effective than the other. Participants will be randomly assigned to either the immediate antibiotic group or the SNAP group at enrollment. Participation lasts 14 days with follow-up surveys at 4, 7, and 14 days after enrollment.

This is a prospective, randomized, controlled, non-inferiority study of patients undergoing tonsil surgeries at Boston Children's Hospital Waltham. The overall aim is to evaluate the efficacy of an opioid anesthetic plan (morphine, ketorolac, and acetaminophen versus an opioid sparing anesthetic plan (dexmedetomidine, ketorolac and acetaminophen) for perioperative analgesia and recovery time in patients undergoing tonsillectomies and tonsillotomies at Boston Children's Hospital Waltham. Secondary measures include rescue opioids administered in post-anesthesia care unit (PACU), re-operation secondary to bleeding, emergence delirium, post-operative nausea and vomiting, intraoperative hemodynamics, intraoperative vasopressor administration, and length of procedure.
