Cefprozil is a cephalosporin antibiotic used for common bacterial infections like strep throat, sinusitis, ear infections, and some skin infections. It won’t work for viruses such as colds or the flu. If a doctor prescribes it, they’ve decided the likely cause is bacterial and that cefprozil is a good choice.
Follow the exact dose your doctor gives you. Adults often take 250–500 mg every 12 hours depending on the infection. Kids get a dose based on weight — that’s why pediatric dosing must come from a prescriber. There’s a tablet and an oral suspension. Shake the suspension well and measure doses with a proper spoon or syringe, not a kitchen spoon.
Take cefprozil with or without food. Keep a steady schedule: if it’s every 12 hours, try to take it at the same times each day. Finish the full course even if you feel better after a few days. Stopping early can let the infection come back or help bacteria become resistant.
Most people tolerate cefprozil well. The common side effects are stomach upset, diarrhea, nausea, and sometimes a rash. If you get severe diarrhea, bloody stools, high fever, or a severe skin reaction, stop the drug and contact your doctor right away — those can signal a more serious issue.
Tell your doctor if you’re allergic to penicillin or other cephalosporins. Cross-reactivity can happen, so they’ll choose the safest option. Also mention kidney problems, history of Clostridioides difficile infection, or if you’re pregnant or breastfeeding — your doctor will weigh risks and benefits.
Drug interactions are usually limited, but talk to your pharmacist about other prescriptions, OTC meds, or supplements you use. If you take oral contraceptives, antibiotics like cefprozil are unlikely to make them fail, but if you experience severe diarrhea, use a backup method until you’re sure the pill is effective.
Store tablets at room temperature in a dry place. For suspensions, follow the label — refrigerated storage is common and you’ll often need to discard leftovers after a set number of days. Keep all antibiotics out of reach of children.
Wondering about buying cefprozil online? Use only licensed pharmacies and a valid prescription. Avoid sites that don’t require a prescription or that offer suspiciously low prices. Your health depends on real medication from trustworthy sources.
If symptoms don’t improve in 48–72 hours or they get worse, call your doctor. Also get medical help for high fever, trouble breathing, swelling of face or throat, or severe allergic reactions. With proper use, cefprozil is an effective option for many routine bacterial infections.
