Cefadroxil is a first-generation cephalosporin antibiotic used to treat common bacterial infections like strep throat, skin infections, and some urinary tract infections. It kills bacteria by interfering with their cell wall, which helps clear infections fast when the bug is susceptible. Doctors prescribe it based on the type of infection and lab results when available.
Cefadroxil comes as capsules, tablets, and a liquid. It’s typically taken once or twice a day depending on the dose. Taking it at the same time each day keeps levels steady and makes it easier to remember. Don’t stop early just because you feel better — stopping too soon can let the infection return or the bacteria become resistant.
Adults often take 1,000 mg once daily or 500 mg every 12 hours for many infections, but specific doses vary by condition and severity. Children’s doses are weight‑based; the liquid form lets doctors adjust precisely. Take with food if stomach upset happens, although it can be taken with or without meals. If you miss a dose, take it as soon as you remember unless it’s near the next planned dose — don’t double up.
For skin infections you might take cefadroxil for 7 to 14 days. For strep throat a shorter 10 day course is common to avoid relapse. Your prescriber will tell you the right length; follow that plan and schedule any recommended follow up.
Common side effects include diarrhea, nausea, and mild rash. Most reactions are mild and go away after treatment ends. Tell your doctor if diarrhea is severe or watery — that could indicate Clostridioides difficile and needs urgent attention. If you have a penicillin allergy, mention it. Some people who react to penicillin also react to cephalosporins, though many tolerate cefadroxil fine. Your clinician will assess risk based on your history.
Cefadroxil can interact with certain drugs like metformin and probenecid, and it may affect lab tests. If you take blood thinners, diabetes meds, or have kidney disease, your dose might need adjustment. Drink water with each dose and store the liquid form in the fridge if directed.
Trust test results and your healthcare provider. If symptoms get worse, fever persists, or you develop allergic signs like swelling or trouble breathing, seek medical help fast. For mild stomach upset, probiotics or yogurt may ease symptoms, but check with your prescriber first.
Alternatives include cephalexin, amoxicillin, or other antibiotics guided by culture results. Buying antibiotics online without a prescription can be risky — use licensed pharmacies and keep a record of what you take. If you’re unsure whether cefadroxil fits your case, ask your provider for clarification. Clear questions help you get the right drug, dose, and duration for a safe recovery.
Keep medicines out of reach of children and check the expiration date before using. Tell your dentist and any specialist you’re on cefadroxil before procedures. Alcohol doesn’t interact strongly but can worsen side effects like dizziness — avoid heavy drinking while on treatment. If side effects persist after finishing the course, call your doctor.
