Urinary tract infections (UTIs) are among the most common infections, affecting millions annually. These uncomfortable infections can cause symptoms such as pain during urination, frequent urges to urinate, and abdominal discomfort. Generally, antibiotics are necessary to treat the infection, and one common medication prescribed is cefdinir.

Cefdinir is a broad-spectrum, third-generation cephalosporin antibiotic that effectively treats various bacterial infections, including UTIs. Though once sold under the brand name Omnicef, cefdinir is now available only as a generic drug following the discontinuation of Omnicef by its manufacturers.

What Is Cefdinir?

Cefdinir belongs to the cephalosporin class of antibiotics, which work by inhibiting the bacterial cell wall formation, causing the bacteria to weaken and eventually die. This makes cefdinir an effective treatment for several bacterial infections, including:

• Bronchitis

• Pneumonia

• Skin infections

• Sinus infections

• Tonsillitis

• Ear infections

• Throat infections

Doctors may also prescribe cefdinir for uncomplicated urinary tract infections. It is commonly used as a second-line treatment when other antibiotics are ineffective or cause unwanted side effects.

How Cefdinir Works for UTIs

When prescribed for a UTI, cefdinir targets and kills the bacteria causing the infection. Common UTI-causing bacteria include E. coli, Klebsiella, and Proteus, which are generally susceptible to cefdinir. Once taken, the medication enters the bloodstream and the infection site, disrupting the bacterial cell walls and helping your body clear the infection.

The typical dosage for cefdinir when treating UTIs is 300 mg, taken twice daily for 3 to 7 days. However, the exact dose and duration depend on several factors, such as the severity of the infection, the person’s age, overall health, and history of recurrent UTIs.

It is crucial to complete the entire course of antibiotics as prescribed, even if symptoms improve before finishing the medication. Stopping an antibiotic course early can allow the infection to return or the bacteria to become resistant to the drug.

How Effective Is Cefdinir?

Cefdinir is commonly prescribed as a second-line treatment for UTIs, meaning that it is used when the initial antibiotic treatment is ineffective or causes side effects. While first-line antibiotics like nitrofurantoin and trimethoprim-sulfamethoxazole are often preferred due to higher cure rates, cefdinir remains a reliable option for those who cannot tolerate or do not respond to first-line treatments.

Research from 2016 indicates that second-line antibiotics, including cefdinir, generally have lower cure rates than first-line options. However, cefdinir has successfully treated UTIs, especially when caused by bacteria susceptible to the drug.

A 2021 study found that cefdinir effectively treated UTIs in children, with a lower failure rate than other antibiotics. This suggests that cefdinir remains a valuable option despite being a second-line treatment, especially for those who experience recurrent or resistant infections.

Side Effects of Cefdinir

Like any medication, cefdinir can cause side effects. Most are mild, but some can be severe. Common side effects of cefdinir include:

• Diarrhea

• Nausea

• Vomiting

• Stomach pain

• Headache

• Vaginal itching

• Cough

• Fever

• Sore throat

In rare cases, more severe side effects can occur, such as:

• Sores, ulcers, or white spots in the mouth or on the lips

• Reddish or black, tarry stools

• Chest pain or shortness of breath

If you experience severe side effects, you should seek medical attention immediately.

Cefdinir Drug Interactions

Cefdinir can interact with other medications, which may affect its efficacy or increase the risk of side effects. Some drugs that may interact with cefdinir include:

• Antacids containing aluminum or magnesium: These can reduce the absorption of cefdinir, making it less effective. If you need to take antacids, take them 2 hours before or 2 hours after cefdinir.

• Iron supplements: These supplements may also interfere with cefdinir absorption, leading to a less effective treatment. Your doctor may suggest spacing out the doses of iron supplements and cefdinir.

• Probenecid: This medication can increase the concentration of cefdinir in the blood, which may raise the risk of side effects.

Always inform your healthcare provider of any other medications or supplements you are taking before starting cefdinir.

Can Cefdinir Be Used for Recurrent UTIs?

For people who experience recurrent UTIs, cefdinir can be an effective option. Recurrent UTIs are defined as having two or more infections in six months or three or more infections in a year. If you have recurrent UTIs, your doctor may recommend cefdinir when other treatments fail or if your body builds resistance to first-line antibiotics.

However, because of the possibility of antibiotic resistance, it’s important to discuss with your healthcare provider whether cefdinir is the right choice for your specific case.
