What infections is cefdinir 300 mg used to treat?
Cefdinir 300 mg is an oral antibiotic in the cephalosporin family. It’s used to treat certain bacterial infections, including:
- Ear infections (otitis media)
- Sinus infections (sinusitis)
- Throat infections (pharyngitis/tonsillitis, typically when caused by susceptible bacteria)
- Skin and soft-tissue infections
- Lower respiratory tract infections (such as bronchitis or community-acquired pneumonia, depending on local guidance and the cause) [1]
How does cefdinir 300 mg work?
Cefdinir kills bacteria by interfering with their cell-wall formation. It works only against bacteria, not viruses (so it won’t help for illnesses like the common cold or flu). [1]
How is it usually taken for adults?
Dosing depends on the specific infection and the prescribing instructions. Many adult regimens use 300 mg once daily or 300 mg twice daily, but you should follow the directions on your prescription label. If you miss a dose, take it when you remember unless it’s close to the next dose. [1]
What should patients know about side effects and safety?
Common side effects can include:
- Diarrhea or loose stools
- Nausea, vomiting, or stomach pain
- Headache
More serious reactions are less common but can include allergic reactions (such as rash, swelling, or trouble breathing). Seek urgent care for signs of a severe allergy. If diarrhea is severe or watery and persistent, contact a clinician promptly. [1]
Who shouldn’t take cefdinir (or needs extra caution)?
Extra caution is needed if you have had a serious allergy to cephalosporins or certain other beta-lactam antibiotics. People with significant kidney disease may require dose adjustments. Tell your clinician about all drug allergies and current medications. [1]
