Effectiveness

How Omnicef Affects PatientsCefdinir 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 bodyCefdinir 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.

Omnicef for Bacterial Urinary Tract Infection
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. I'm not sure if the two are related, but it's something to be aware of if you're considering this treatment for your child.

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?

We tried this drug with our 11 month old son for his ear infections, but he broke out into hives after only two days. There are clearly better options out there.

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!
