Cefprozil (Oral)

Cefprozil is an effective treatment for infections of all types, although it does not work on viral infections such as the flu and the common cold.


Patients that are suffering from bacterial infections often receive relief from their symptoms when taking cefprozil as long as they are not caused by a virus. This drug is effective because it kills bacteria and also prevents the bacteria from growing any further.

Typically, cefprozil is prescribed for conditions such as sore throats, sinusitis, bronchitis, ear infections, skin infections, and tonsillitis. Any type of flu, cold, or other viral infection will not respond to cefprozil and thus it should not be taken by patients suffering from those ailments.

The drug can be administered in both tablet and liquid form. If you are prescribed the liquid form it is important to store it in the refrigerator.

Cefprozil does not interact with many major drugs with Probenecid being the only one. If you are currently taking this drug, or have taken it in the recent past, be sure to discuss this with your doctor. They may alter your dosage of cefprozil or prescribe another drug altogether. Be sure to always inform your prescribing doctor and pharmacist of all the drugs and medications that you are taking. This includes both prescription and non-prescription drugs as well as herbal remedies and vitamin and mineral supplements.

This medication can cause severe diarrhea and if you suffer from this ailment, be sure to confer with your doctor before you take any anti-diarrhea medications as they can prolong the affliction or even make it worse. If any side effects continue to linger more than a few days or appear to become worse, it is advised that you contact your prescribing doctor as soon as possible. While most side effects do go away on their own, instances where they last more than a few days may be a sign of a more serious problem.

Be sure to take cefprozil for the entire 10-day course of treatment for however long your doctor prescribes it to you as the entire dosage is necessary to ensure that the infection does not return. Many patients report relief from their symptoms after only one or two doses but, even in such cases, the entire dosage cycle should be taken.

Children who are suffering from an infection may be prescribed cefprozil by their pediatrician or family doctor. The dosage amounts for use of cefprozil by children will vary and is typically based on their weight. Be sure to follow the exact instructions provided by your pediatrician or family doctor and contact them with any questions or concerns that you may have while your child is taking this drug.
