About Omnicef (cefdinir)
Cefdinir is considered a third-generation cephalosporin antibiotic, which functions by killing bacteria. The mechanism of action involves inhibiting bacterial cell wall synthesis by binding to penicillin-binding proteins. In other words, cefidinir stops bacteria from growing.
Like any antibiotic, this medication can only be used for bacterial infections. It is ineffective against colds, flu, and other viral infections because it will not destroy viruses, only bacteria. It is important to remember that use of antibiotics for viral infections will not help you heal faster, and will only lead to possible side effects and antibiotic resistance.
Some conditions that cefdinir is known to treat include bacterial infections such as bacterial sinus infections, pneumonia, and others. Cefdinir is available only by prescription. It is available in a generic formulation under different brand names, including Omnicef Omni-Pac.
Cefdinir may be prescribed as a capsule and powder for suspension (liquid) to take by mouth. It’s always important to follow the specific instructions on your prescription, as they can vary based on the formulation and dosage you are prescribed.
If you are prescribed Omnicef or cefdinir orally, complete the entire course of the cephalosporin antibiotic unless your doctor specifically tells you to stop.
The cephalosporin antibiotic may only fully treat your bacterial infection if you complete your prescription.
Cefdinir uses
There are several FDA-approved uses for cefdinir oral to treat a variety of mild to moderate infections resulting from bacteria, but it may also be used off-label to treat other conditions. Your online doctor may prescribe Omnicef for any of the following common reasons.
It’s also possible that your healthcare provider may prescribe it for other reasons not listed here. If you have questions about why a medication is prescribed, ask your online doctor.
Variety of infections caused by bacteria
Additionally, cefdinir is used to treat infections caused by bacteria of the middle ear (e.g. acute bacterial otitis media) and bacterial urinary tract infections, and other types of infections caused by bacteria.
Cefdinir works by killing bacteria or preventing their growth. As with other cephalosporin antibiotics, Omnicef manages infections produced by gram-positive and gram-negative bacteria.

How to take cefdinir
Your pharmacist will provide you with instructions on how to take your cefdinir prescription.
Be sure to read your prescription label and follow the instructions. Call your doctor or pharmacy if you have any questions or need more drug information.
Cefdinir can come in different forms and doses, so be sure to follow the specific instructions on your prescription. It is typically prescribed twice a day, i.e. every 12 hours. Some specific instructions may include taking 300 mg capsule every 12 hours or 600mg once a day, for adolescents and adults.
For infants taking liquid Cefdinir and children six months up to 12 years of age, the dosage is based on body weight. It is usually 7mg per kg of body weight every 12 hours or 14mg per kg of body weight per day. The dosage is not higher than 600mg a day.
Cefdinir is usually taken for 5 to 10 days.
What to avoid while taking cefdinir
Additionally, cefdinir could affect the results of some lab tests, including a false-positive reaction for ketones in urine with tests using nitroprusside.
Don’t change what you are taking without checking with your doctor or pharmacist. That includes other medications or supplements, as well as over-the-counter drugs.
It is important to follow the doctor’s or pharmacist’s instructions when taking cefdinir. Inform laboratory personnel about cefdinir use if you are scheduled to do certain lab tests.
They will tell you whether you can do medical tests when taking the antibiotic or if you will need to wait for the treatment course to finish first.
Ask your doctor or pharmacist if it is acceptable to consume alcohol while taking cefdinir.
Some research shows that regular alcohol consumption may exacerbate the side effects of cefdinir, make your symptoms worse, and cause severe drowsiness. Alcohol may also reduce the medication’s ability to do its job, making it harder to treat bacterial infections.
Avoid taking mineral supplements within two hours before or after taking the usual dose of cefdinir.
Medication alternatives to cefdinir
If your healthcare provider prefers to put you on another treatment altogether, they may suggest another cephalosporin antibiotic or an antibiotic in another drug class. Here are some common doctor-recommended alternatives based on your health issue:
Pneumonia
Ear infection
Pharyngitis/tonsillitis
Skin infections
