Cephalosporin is an antimicrobial agent that destroys infections caused by bacteria, especially respiratory ones. Administered orally, this second-generation cephalosporin impairs cell wall synthesis in bacteria, weakening them, rupturing their membrane, and eventually killing the bacteria.

This oral antibiotic treats common diseases such as bronchitis, sinusitis, and otitis media. A study revealed that the bioavailability rates of cefprozil are as high as 95% when given orally, and that it can attain peak plasma levels in 1.5 hours of administration, making it a fast-acting antibiotic.

How Does Cefprozil Work?

Cefprozil attaches to penicillin-binding proteins, inhibiting peptidoglycan crosslinking in the cell wall. This damages their wall structure and kills the bacteria. Among these infections, Cefprozil is helpful as an antibacterial capable of combating resistance to even more developed cases.

This medication is usually administered once or twice daily for a period ranging from 10 days in general. The dosage should be completed and taken following the physician’s direction to prevent resistance.

Cefprozil Precautions and Warnings

There are several essential cautionary notes and warnings that you should heed before taking the antibiotic Cefprozil. Some include:

  • Urine Glucose Testing: Cefprozil interferes with urine glucose testing and may cause false positives. Notify the lab before taking a test.
  • Infants: Not recommended for infants six months and younger with ear infections or sinusitis. Also, Cefprozil doesn’t cover children under two years for throat and skin abscesses since such safety efficacy has yet to be established.
  • Pregnant and Breastfeeding Women: Be careful and consult with your doctor first before using this antibiotic because Cefprozil excretes into milk when breastfeeding. Similarly, safety has not been established for pregnant women.
  • Alters Urine Ketone Tests: Cefprozil may cause false positives for people with diabetes (due to diabetic medication) during urine ketone tests; the liquid version of this antibiotic contains phenylalanine (which is harmful to Phenylketonuria).

Cefprozil Side Effects

One data study found Cefprozil to have comparable efficacy to amoxicillin/clavulanate for treating acute otitis media, but with significantly fewer side effects, amoxicillin/clavulanate for treating acute otitis media—however, with significantly fewer side effects—especially gastrointestinal issues. However, you should still consult your provider about potential reactions.

Common Side Effects

  • Leukopenia (reduced white blood cell count)

Cefprozil Drug Interactions

Some medications interact with Cefprozil, altering its effectiveness or causing other side effects. As such, please let your doctor know about any additional medications you are taking, like vitamins, over-the-counter medicines, and herbal remedies.

Alcohol, tobacco, and certain foods could also interact with Cefprozil. You should, therefore, discuss your Cefprozil usage recommendations related to diet, drinking, or smoking with your healthcare professional.

While Cefprozil cannot be taken with certain drugs, a combined regimen could, however, still be optimal depending on a patient’s condition. If prescribed together, the doctor or pharmacist may adjust the dosage or frequency of either medication for efficacy and to prevent severe side effects.

There are specific drugs that are usually not recommended for concurrent usage with Cefprozil, including:

  • Drospirenone (found in Yaz)
  • Norethindrone
  • Norgestimate
  • Norgestrel
  • Cholera vaccines, Live
  • Various hormonal birth control methods containing desogestrel
  • Dienogest
  • Estradiol (such as Vagifem)
  • Ethinyl estradiol
  • Ethynodiol
  • Gestodene
  • Levonorgestrel

  • Anticoagulants (blood thinners such as Eliquis and Xarelto)
  • Probenecid or oral contraceptives.

How to Use Cefprozil Suspension

Cefprozil suspension is an oral medication that can be taken once or twice a day. Shake the bottle well before usage to allow uniform mixing of the medicine. You can then measure the dose with a syringe, spoon, or dropper provided and administer it appropriately.

Children should be dosed by weight, and you must ensure you balance out your doses so that the amount of drug is continuously achieved. You may take Cefprozil with or without food. Taking it with food might lessen aggression to the stomach.

Common symptoms of infection may subside after a few days of taking antibiotics. However, it does not mean the issue is resolved. Follow the entire course as your physician recommends to prevent a new form of infection.

Cefprozil Strengths and Dosages

Cefprozil comes in two forms: oral tablets and powder for suspension. These forms enable dosage flexibility across different strengths and suit varying patients.

FormulationStrengthsTypical Adult DoseTypical Children’s Dose
Tablets250 mg, 500 mg250-500 mg every 12-24 hoursNot recommended
Powder for Oral Suspension125 mg/5 mL, 250 mg/5 mL250-500 mg every 12 hours7.5-20 mg/kg every 12-24 hours

Cefprozil is accessible in different formulations and strengths, allowing customized dosage regimens per patient’s age, weight, kidney function, and infection profile. Still, close provider supervision is needed to determine optimal personal dosage.

  • For adults and individuals older than thirteen years, the drug is available in tablets of 250-500mg. The tablets are administered every 12 to 24 hours for about a week, depending on the severity of the illness.
  • Dosages for children between 6 months to 12 years of age are generally weight-based, with 7.5–15 mg/kg every 12 hours or a complete dose of about 20mg/kg once a day.

Cost of Cefprozil in America

The average retail price for the most commonly prescribed Cefprozil oral suspension is $124.60 for 50 mL. However, patients can obtain it less if they qualify for coupons and discounts.

The table above shows a cost comparison between Cefprozil and two alternative antibiotics

  • Augmentin is substantially more expensive than Amoxicillin which provides a lower-cost alternative.
  • All three drugs are commonly prescribed antibiotics to treat bacterial infections. However, their drug class and approval differ.
