Understanding what cefdinir is used for, when it’s prescribed, and its key considerations can help patients and caregivers feel confident about their treatment options.

Essential Highlights

Cefdinir is primarily used to treat respiratory tract infections, ear infections, sinus infections, throat infections, and uncomplicated skin infections caused by susceptible bacteria.
It is effective for both children (as young as 6 months) and adults, but only for bacterial—not viral—infections.
Doctors typically prescribe cefdinir when the infection is proven or strongly suspected to be bacterial to avoid overuse and resistance.
Cefdinir is available as an oral capsule or liquid suspension for convenient at-home treatment.

Understanding Cefdinir: Overview and Mechanism

Cefdinir is a third-generation cephalosporin antibiotic designed to combat a broad range of bacterial infections. It works by preventing bacteria from forming cell walls, effectively killing the bacteria and stopping the infection from spreading[1][7].

Formulations: Available in oral capsules and oral suspension.
Suitable for: Adults and children 6 months and older.
Not effective against: Viral infections such as the flu or common cold[3].

Main Uses of Cefdinir

Cefdinir targets a variety of infections—especially those caused by susceptible bacteria.

Respiratory Tract Infections

Acute exacerbations of chronic bronchitis
Community-acquired pneumonia
Acute maxillary sinusitis (sinus infections)[1][3][5][7]

Ear, Nose, and Throat Infections

Acute bacterial otitis media (middle ear infection) in children
Pharyngitis and tonsillitis (including strep throat)[1][3][5][7]

Skin and Soft Tissue Infections

Uncomplicated skin and skin structure infections such as mild cellulitis and impetigo[3][5][7]

Cefdinir is commonly prescribed for:
– Patients with penicillin allergies who require alternatives for upper respiratory or ear infections[5].
– Children and adults with mild to moderate infections when confirmed bacterial cause is likely or proven.

How Cefdinir Is Prescribed

Doctors consider the type, location, and severity of infection—plus patient age and allergies—when prescribing cefdinir.

Dosage: Typical adult dose is 300 mg every 12 hours or 600 mg once daily; children’s dosing is weight-based[3][7].
Duration: Courses usually last 5–10 days depending on the infection and patient response.
Diagnosis: Often guided by symptoms and, when needed, lab cultures to confirm bacterial cause[3].

Cefdinir should be taken exactly as directed—even if you feel better partway through the course. Stopping early can allow infection to return and promote antibiotic resistance.

Important Considerations and Side Effects

While cefdinir is generally well-tolerated, some common and rare side effects can occur.

Common Side Effects

Diarrhea
Nausea or vomiting
Headache
Rash[7]

Serious (but Rare) Side Effects

Severe allergic reactions (e.g., anaphylaxis, swelling, difficulty breathing)
Persistent or severe diarrhea (may indicate Clostridioides difficile infection)
Changes in stool color in infants (due to interaction with iron)

Alert your healthcare provider if you experience any severe or persistent symptoms.

Important Safety Tips:
– Do not use cefdinir for viral infections.
– Inform your doctor about allergies, especially to penicillins or other cephalosporins.
– People with kidney disease should consult their doctor before use[7].
