# Forcef (Cephradine)
## Overview
Cephradine is a first-generation cephalosporin antibiotic. It possesses a spectrum of activity primarily targeting Gram-positive cocci (excluding MRSA) and a limited range of Gram-negative bacteria (e.g., *E. coli*, *P. mirabilis*, *K. pneumoniae*). It is available in oral formulations (capsules, suspension) and parenteral forms.
## Primary Indications
* Respiratory tract infections.
* Urinary tract infections (UTIs).
* Skin and skin structure infections.
* Otitis media.
* Surgical prophylaxis.
## Adult Dosing
* **Mild to Moderate Infections:** 250 mg to 500 mg orally every 6 hours.
* **Severe Infections:** Up to 1 g orally every 6 hours or 500 mg to 1 g IV/IM every 6 hours.
* **Maximum Dose:** Generally 4 g per day. Doses up to 8 g per day may be used in severe infections by parenteral route; consult specific institutional guidelines.
## Pediatric Dosing
* **Oral:** 25–50 mg/kg/day divided every 6 or 12 hours.
* **Parenteral:** 50–100 mg/kg/day divided every 6 hours.
* *Note:* Maximum pediatric dose should not exceed the maximum adult dose. Safety in infants <1 month is not well established.
## Dose Adjustments
* **Renal Impairment:** Requires dose reduction in patients with creatinine clearance (CrCl) <20 mL/min.
* CrCl 10–20 mL/min: Reduce dose by 50%.
* CrCl <10 mL/min: Reduce dose by 75%.
* **Hepatic Impairment:** No specific guidelines; use with caution.
## Contraindications
* Hypersensitivity to cephradine or any cephalosporin.
* History of severe allergic reaction (e.g., anaphylaxis) to penicillins or other beta-lactams (due to potential cross-reactivity).
## Adverse Effects
* **Common:** Nausea, vomiting, diarrhea, abdominal pain.
* **Serious:** *Clostridioides difficile*-associated diarrhea (CDAD), hypersensitivity reactions (rash, pruritus, anaphylaxis), neutropenia, elevated liver enzymes.
* **Rare:** Seizures (at very high doses or in renal failure), interstitial nephritis.
## Key Drug Interactions
* **Probenecid:** Increases and prolongs serum levels of cephradine by decreasing renal tubular secretion.
* **Aminoglycosides:** May theoretically increase the risk of nephrotoxicity.
* **Warfarin:** Cephalosporins may alter intestinal flora, potentially increasing the anticoagulant effect of warfarin (monitor INR).
## Monitoring
* **Renal Function:** Monitor BUN and serum creatinine in patients with existing impairment.
* **Efficacy:** Resolution of symptoms and clinical improvement.
* **Safety:** Monitor for signs of superinfection or *C. difficile* diarrhea (persistent watery/bloody stools).
## Clinical Pearls
* **Cross-reactivity:** Patients with a history of severe, IgE-mediated reactions to penicillin should generally avoid cephalosporins.
* **Administration:** May be taken with or without food; take with food if gastrointestinal upset occurs.
* **Stability:** Ensure parenteral doses are prepared according to specific manufacturer or pharmacy compounding guidelines for concentration and stability.
* **Dosing Variation:** Always refer to local facility antibiograms for resistance patterns, as susceptibility of local pathogens to first-generation cephalosporins varies widely.
