⚡ Quick Answer — What is Cefadur?
Cefadur is a cefadroxil capsule (500 mg, Indi Pharma) — a first-generation oral cephalosporin similar to cefalexin but with a longer half-life supporting twice-daily dosing. Used for skin / soft-tissue infections, streptococcal pharyngitis, and uncomplicated UTI.

How Cefadur works
Cefadur contains Cefadroxil, a first-generation cephalosporin with strong activity against Gram-positive cocci (Streptococcus, methicillin-sensitive Staphylococcus aureus) and limited Gram-negative cover (E. coli, Proteus mirabilis, Klebsiella). It is bactericidal via inhibition of cell-wall synthesis at penicillin-binding proteins. Resistance arises through extended-spectrum beta-lactamases (ESBLs), AmpC, and reduced porin permeability — none of these cephalosporins should be used empirically when ESBL/AmpC organisms are likely.
Indications & dosing
| Indikace | Standardní dávka | Délka |
|---|---|---|
| Skin and soft-tissue infection (cellulitis, impetigo) | 500 mg four times daily (cefalexin) / 500 mg twice daily (cefadroxil) | 7 dnech |
| Streptococcal pharyngitis | 500 mg twice daily | 10 days |
| Uncomplicated UTI in pregnancy (sensitive E. coli) | 500 mg four times daily / cefadroxil 1 g twice daily | 5–7 days |
| Surgical prophylaxis (clean surgery — IV cefazolin equivalent) | Per surgical protocol | Single dose |
Renal dose adjustment: all oral cephalosporins require dose extension below CrCl 30 — confirm with a clinical pharmacist for severe renal impairment. Ceftriaxone (which is biliary-excreted) does NOT need renal adjustment.
Vedlejší účinky
- Gastrointestinální: nausea, diarrhoea (5–10%); higher with cefixime and cefpodoxime than with cephalexin.
- Přecitlivělost: 5–10% cross-reactivity with penicillin allergies (lower than once thought; ~0–2% with non-anaphylactic penicillin reactions).
- Clostridioides difficile colitis: elevated risk versus narrow-spectrum agents — broad cephalosporins are the second-most C. difficile-driving class after fluoroquinolones.
- Haematological: rarely eosinophilia, thrombocytosis, neutropenia.
- Ledviny: rare interstitial nephritis; dose-dependent rises in serum creatinine reported with high-dose IV cephalosporins.
- Ceftriaxone-specific: biliary pseudolithiasis (gallbladder sludge) — usually asymptomatic, reverses on stopping.
Kontraindikace
- Previous IgE-mediated cephalosporin allergy.
- Anaphylactic-class penicillin allergy without skin-test clearance.
- Severe renal impairment without dose adjustment (oral cephalosporins).
- Neonates with hyperbilirubinaemia — ceftriaxone displaces bilirubin from albumin (kernicterus risk).
Interakce léků
| Lék | Účinek | Action |
|---|---|---|
| Warfarin | Slight INR rise (especially with N-methylthiotetrazole-side-chain cephalosporins) | Check INR mid-course |
| Calcium IV (neonates) | Lethal precipitation with ceftriaxone | Absolute contraindication ≤ 28 days |
| Probenecid | Raises serum levels (oral cephalosporins) | No routine adjustment |
| Antacids / H2 blockers | Reduces absorption of cefpodoxime | Separate by 2 hours |
| Aminoglycosides | Possible additive nephrotoxicity (high-dose IV) | Monitor renal function |
Pregnancy & Breastfeeding
Cephalosporins are FDA category B — extensively used in pregnancy without evidence of fetal harm. They are first-line alternatives in penicillin-allergic patients without an anaphylactic history.
Skladování
Store below 25 °C, away from direct sunlight and moisture. Keep in original packaging. Keep out of reach of children. Discard any unused tablets after the printed expiry date — degraded antibiotics can lose potency or release breakdown products.
This medicine is only effective against bacterial infections. Do not use it for viral illnesses (common cold, most sore throats, flu, COVID-19), do not stop early when you feel better, and do not save leftovers for future infections. Misuse drives drug-resistant bacteria like MRSA, ESBL, and CRE — the WHO ranks antimicrobial resistance among the top 10 global public-health threats.
Často kladené dotazy
Can I take Cefadur if I am allergic to penicillin?
It depends on the type of penicillin reaction. If you had anaphylaxis, severe urticaria, angioedema, or Stevens–Johnson syndrome — avoid all beta-lactams without specialist clearance. If your reaction was a mild delayed rash, modern allergy guidance considers cephalosporin use generally safe — discuss with your prescriber.
Why do cephalosporins cause more diarrhoea than penicillins?
Cephalosporins disturb anaerobic gut flora more aggressively, particularly when poorly absorbed (cefixime is ~50% absorbed; cefpodoxime ~40%). This raises C. difficile colonisation pressure. Stop and seek review for new watery diarrhoea, especially with fever or abdominal pain.
How quickly should I feel better?
Most uncomplicated infections improve within 48–72 hours. If you are no better by day 3 — or worse — seek review. The pathogen may be resistant or the diagnosis incorrect.
Můžu pít alkohol?
Most cephalosporins do not produce a disulfiram-like reaction. (Older agents like cefamandole and cefoperazone did — these are not used here.) Moderate alcohol is fine; binge drinking weakens immune response.
Should I take it with food?
Cephalexin and cefadroxil are absorbed equally with or without food. Cefpodoxime absorption is increased ~50% by food and decreased by acid suppressants — take it WITH a meal and separate from antacids by 2 hours.
Co když vynechám dávku?
Take it as soon as you remember. If close to the next scheduled dose, skip the missed one and resume. Never double up.
Can I use Cefadur for a viral cold?
No — cephalosporins are bactericidal and have no activity against viruses. Inappropriate use accelerates resistance and disturbs your gut and respiratory flora. Use only for confirmed bacterial infections.
Will Cefadur cover Pseudomonas?
No — only ceftazidime and cefepime among cephalosporins have reliable Pseudomonas activity, and neither is used here. Cefadroxil should not be used empirically when Pseudomonas is suspected.
Will it interact with my warfarin?
Yes — INR may rise. Check INR 3–5 days into therapy and counsel on bleeding signs. Adjust warfarin dose only on physician advice.
Are cephalosporins safe in breastfeeding?
Yes — milk transfer is minimal. WHO and AAP rate cephalosporins as compatible with breastfeeding. Watch the infant for thrush or diarrhoea, but no maternal dose change is needed.
