Cefdinir is a prescription semi-synthetic (partially man-made) oral antibiotic in the cephalosporin family of antibiotics. The cephalosporin family includes:
- cephalexin (Keflex)
- cefaclor (Ceclor)
- cefuroxime (Zinacef)
- cefpodoxime (Vantin)
- cefixime (Suprax), cefprozil (Cefzil)
- Many injectable antibiotics
Note: Omnicef brand has been discontinued and there are no other brand names available for cefdinir available in the US
What are the uses for cedinir?
Cefdinir is effective against susceptible bacteria causing infections of the following:
- Middle ear (otitis media)
- Tonsils (tonsillitis)
- Throat (strep throat)
- Larynx (laryngitis)
- Sinuses (sinusitis)
- Bronchi (bronchitis)
- Lungs (pneumonia)
- Skin and other soft tissues
Cefdinir is not active against Pseudomonas.
What are the side effects of cefdinir?
- Cefdinir generally is well tolerated. The most common side effects are:
- Rare side effects include:
- Cefdinir may cause false test results with some tests for sugar in the urine.
- Like most antibiotics, cefdinir may cause a condition called pseudomembranous colitis (Clostridium difficile colitis), a potentially serious bacterial infection of the colon. Patients who develop signs of pseudomembranous colitis after starting cefdinir (diarrhea, fever, abdominal pain, and possibly shock) should contact their doctor immediately.
- Persons who are allergic to the penicillin class of antibiotics, for example, amoxicillin, amoxicillin, and clavulanic acid (Augmentin), which are related to cephalosporins, may or may not be allergic to cephalosporins.
What is the dosage for cefdinir?
- Cefdinir is taken once or twice daily, depending on the type and severity of the infection.
- The capsules or suspension can be taken with or without food.
- Patients with advanced kidney disease may need to take lower doses to prevent the accumulation of cefdinir since it is eliminated from the body by the kidneys.
- For adult infections, the usual dose is 300 mg every 12 hours or 600 mg per day for 5-10 days depending on the nature and severity of the infection.
- The recommended dose for children 6 months to 12 years of age is 7 mg/kg every 12 hours or 14 mg/kg per day for 5-10 days depending on the type of infection.
- For most infections, once-daily dosing is as effective as twice-daily dosing, although once-daily dosing has not been evaluated for the treatment of skin infections or pneumonia.
Which drugs or supplements interact with cefdinir?
- Aluminum or magnesium-containing antacids reduce the absorption of cefdinir from the intestine. Separating the administration of cefdinir and such antacids by two hours prevents this interaction.
- Iron supplements also reduce the absorption of cefdinir. Separating the administration of cefdinir and iron supplements by two hours prevents this interaction. There have been reports of reddish stool in patients who have received cefdinir. This could be due to the formation of a chemical complex between cefdinir and iron in the stomach.
- Cefdinir has serious interactions with the following drugs:
- Cefdinir has moderate interactions with at least 25 other drugs.
- Cefdinir has minor interactions with the following drugs:

How does cefdinir work?
- Like other cephalosporins, cefdinir stops bacteria from multiplying by preventing bacteria from forming the walls that surround them. The walls are necessary to protect bacteria from their environment and to keep the contents of the bacterial cell together. Bacteria cannot survive without a cell wall. Cefdinir is active against a very wide spectrum of bacteria, including
Therapeutic uses of cefdinir include otitis media (infections of the middle ear), infections of soft tissues, and respiratory tract infections.

Laryngitis is an inflammation of the voice box (vocal cords). The most common cause of acute laryngitis is an infection, which inflames the vocal cords. Symptoms may vary from the degree of laryngitis and age of the person (laryngitis in infants and children is more commonly caused by croup).
Middle Ear Infection (Otitis Media)
A middle ear infection (otitis media) can cause earache, temporary hearing loss, and pus drainage from the ear. It is most common in babies, toddlers, and young children. Learn about causes and treatment.
Sore Throat Home Remedies
Natural and home remedies for sore throat symptoms and pain relief include essential oils, licorice gargles, slippery elm leaves, raw garlic, Throat Coat tea, sage, and acupuncture. Typical symptoms of a sore throat include throat pain, coughing, sneezing, fever, and swollen lymph nodes. Sore throats are caused by viral (common cold, flu, mumps), bacterial (tonsillitis, some STDs), toxins, allergens, trauma or injury, or "mechanical causes" (breathing through the mouth).
Tonsillitis is a contagious infection with symptoms of bad breath, snoring, congestion, headache, hoarseness, laryngitis, and coughing up blood. Tonsillitis can be caused by acute infection of the tonsils, and several types of bacteria or viruses (for example, strep throat or mononucleosis). There are two types of tonsillitis, acute and chronic. Acute tonsillitis lasts from 1-2 weeks while chronic tonsillitis can last from months to years. Treatment of tonsillitis and adenoids include antibiotics, over-the-counter medications, and home remedies to relieve pain and inflammation, for example, saltwater gargle, slippery elm throat lozenges, sipping warm beverages and eating frozen foods (ice cream, popsicles), serrapeptase, papain, and andrographism Some people with chronic tonsillitis may need surgery (tonsillectomy or adenoidectomy).
Is Strep Throat Contagious?
Strep throat is caused by group A streptococcus bacteria. Incubation period for strep throat is 1-5 days after exposure. If strep throat is treated with antibiotics, it is no longer contagious after 24 hours; if it is not treated with antibiotics, it is contagious for 2-3 weeks. Symptoms include fever, sore throat, tonsillitis, white spots or patches on the tonsils, and nausea and vomiting. Diagnosis of strep throat is performed through a rapid strep test.
Strep throat is a bacterial infection of the throat. Signs and symptoms of strep throat include headache, nausea, vomiting, sore throat, and fever. Strep throat symptoms in infants and children are different than in adults. Strep throat is contagious and is generally passed from person to person. Treatment for strep throat symptoms includes home remedies and OTC medication; however, the only cure for strep throat is antibiotics.
Pneumonia is inflammation of the lungs caused by fungi, bacteria, or viruses. Symptoms and signs include cough, fever, shortness of breath, and chills. Antibiotics treat pneumonia, and the choice of the antibiotic depends upon the cause of the infection.
Staph (Staphylococcus) Infection
Staphylococcus or staph is a group of bacteria that can cause a multitude of diseases. Staph infections can cause illness directly by infection or indirectly by the toxins they produce. Symptoms and signs of a staph infection include redness, swelling, pain, and drainage of pus. Minor skin infections are treated with an antibiotic ointment, while more serious infections are treated with intravenous antibiotics.
Is Pneumonia Contagious?
Pneumonia is inflammation of the lung usually caused by bacterial or viral infection (rarely, also by fungi) that causes the air sacs to fill with pus. If inflammation affects both lungs, the infection is termed double pneumonia. If it affects one lung, it is termed single pneumonia. If it affects only a certain lobe of a lung it's termed lobar pneumonia. Most pneumonias are caused by bacteria and viruses, but some pneumonias are caused by inhaling toxic chemicals that damage lung tissue.
Is Laryngitis Contagious?
Laryngitis is inflammation and swelling of the voice box (larynx). Causes of laryngitis are viral, bacterial, fungal, strenuous singing or talking, chemical irritants, and other underlying medical conditions. Symptoms of laryngitis are hoarseness, a weak or loss of voice, sore throat, dry throat, a tickling sensation in the back of the throat, or irritated or raw throat. Treatment of laryngitis depends upon the cause.
Bronchitis is inflammation of the airways in the lung. Acute bronchitis is short in duration (10-20 days) in comparison with chronic bronchitis, which lasts for months to years. Causes of acute bronchitis include viruses and bacteria, which means it can be contagious. Acute bronchitis caused by environmental factors such as pollution or cigarette smoke is not contagious. Common symptoms for acute bronchitis include nasal congestion, cough, headache, sore throat, muscle aches, and fatigue. Acute bronchitis in children also my include runny nose, fever, and chest pain. Treatment for acute bronchitis are OTC pain relievers, cough suppressants (although not recommended in children), and rest. Infrequently antibiotics may be prescribed to treat acute bronchitis.
Is Sore Throat (Pharyngitis) Contagious?

Causes of chronic bronchitis include cigarette smoking, inhaled irritants, and underlying disease processes (such as asthma, or congestive heart failure). Symptoms include cough, shortness of breath, and wheezing. Treatments include bronchodilators and steroids. Complications of chronic bronchitis include COPD and emphysema.
E. coli (0157:H7) Infection
There are many types of E. coli (Escherichia coli). E. coli can cause urinary tract and bladder infections, or lead to sepsis. E coli O157:H7 (EHEC) causes bloody diarrhea and colitis. Complications of E. coli infection include hemorrhagic diarrhea, hemolytic-uremic syndrome, and thrombotic thrombocytopenic purpura. Symptoms include severe abdominal pain and bloody diarrhea. E coli O157:H7 commonly is due to eating raw or undercooked hamburger or raw milk or dairy products.
Group A streptococcal infections are caused by group A Streptococcus, a bacteria that causes a variety of health problems, including strep throat, impetigo, cellulitis, erysipelas, and scarlet fever. There are more than 10 million group A strep infections each year.
Emphysema, Chronic Bronchitis, and Colds
If you have a COPD such as emphysema, avoiding chronic bronchitis and colds is important to avoid a more severe respiratory infection such as pneumonia. Avoiding cigarette smoking, practice good hygeine, stay away from crowds, and alerting your healthcare provider if you have a sinus infection or cold or cough that becomes worse. Treatment options depend upon the severity of the emphysema, bronchitis, or cold combination.
