Cefdinir is an antibiotic that belongs to the cephalosporin class of medications. It is used to treat certain bacterial infections by stopping the growth of bacteria and helping the body fight and clear the infection.
This medication is available as capsules or as a powder that is mixed with water to form an oral suspension. Cefdinir is commonly prescribed for both adults and children and is taken by mouth.
Cefdinir only works against infections caused by bacteria and is not effective for viral illnesses such as the common cold or flu. The length of treatment usually depends on the type and severity of the infection being treated.
Indications for use
Cefdinir is used to treat several types of bacterial infections that affect different parts of the body.
Common indications include:
-
Acute otitis media (middle ear infection)
-
Acute bacterial sinusitis
-
Pharyngitis and tonsillitis caused by certain bacteria
-
Skin and skin structure infections
In some situations, cefdinir may be prescribed when a patient cannot take other antibiotics, such as penicillin. Pediatric treatment guidelines also include cefdinir as an option for children with certain bacterial infections, particularly when a penicillin allergy is present.
How to take it
Cefdinir should be taken exactly as prescribed by a healthcare professional. The dose, frequency, and duration of treatment depend on the type of infection, the patient’s age, and other health factors.
1. Capsules
For adults and adolescents, cefdinir capsules are usually taken once or twice per day. Treatment commonly lasts between 5 and 10 days depending on the infection.
Capsules should be swallowed whole with water and may be taken with or without food.
2. Oral suspension
Cefdinir is also available as a powder that is mixed with water to make a liquid suspension. This form is often prescribed for children.
The dose for children is typically based on body weight and may be given once daily or divided into two doses per day. The suspension should be shaken well before each dose to ensure the medication is evenly mixed.
People with significant kidney impairment may require a lower dose of cefdinir. Adjusting the dosage helps prevent excessive levels of the medication from building up in the body.
Possible side effects
Like all medications, cefdinir may cause side effects in some people. Most side effects are mild and improve after treatment is completed.
Common side effects include:
-
Diarrhea
-
Nausea
-
Vomiting
-
Abdominal pain
-
Headache
-
Skin rash
Some people may also experience changes in laboratory test results, such as mild changes in blood counts or liver enzyme levels.
Although uncommon, serious reactions can occur. These may include severe allergic reactions, serious skin reactions, or diarrhea caused by Clostridioides difficile infection. Medical evaluation is necessary if severe or persistent symptoms occur.
Contraindications for use
The medication is contraindicated in people who:
-
Have a known allergy to cefdinir
-
Have had severe allergic reactions to cephalosporin antibiotics
-
Have experienced serious hypersensitivity reactions to beta-lactam antibiotics
Caution may also be necessary for people with kidney disease, since dosage adjustments may be required.
Use during pregnancy and breastfeeding
Cefdinir should only be used during pregnancy when clearly necessary. There are limited well-controlled studies in pregnant women.
Small amounts of cephalosporin antibiotics may pass into breast milk. Healthcare professionals usually weigh the benefits of treatment against potential risks before recommending cefdinir during breastfeeding.
