# Forcef (cephradine)
## Overview
Cephradine is a first-generation cephalosporin antibiotic. It acts by inhibiting bacterial cell wall synthesis. It is bactericidal and possesses activity against Gram-positive cocci (e.g., *Staphylococcus aureus*, *Streptococcus pyogenes*) and limited Gram-negative activity (*E. coli*, *Klebsiella*, *Proteus mirabilis*).
## Primary Indications
* Respiratory tract infections
* Urinary tract infections (UTIs)
* Skin and skin structure infections
* Otitis media
* Bone infections (osteomyelitis)
## Adult Dosing
* **Mild to moderate infections:** 250 mg to 500 mg orally every 6 to 12 hours.
* **Severe infections:** Up to 1 g orally every 6 hours.
* **Maximum daily dose:** 4 g daily.
## Pediatric Dosing
* **General dosing:** 25 mg/kg to 50 mg/kg daily in divided doses every 6 to 12 hours.
* **Otitis media:** 75 mg/kg to 100 mg/kg daily in divided doses every 6 to 12 hours.
* **Maximum daily dose:** 4 g (not to exceed adult maximum).
## Dose Adjustments
* **Renal Impairment:** Requires interval or dose adjustment based on creatinine clearance (CrCl).
* CrCl 20–50 mL/min: Reduce dose or increase interval.
* CrCl 5–20 mL/min: Increase dosing interval (e.g., every 12–24 hours).
* CrCl <5 mL/min: Use with caution; further interval extension required.
* **Hepatic Impairment:** No specific data; monitor closely.
## Contraindications
* Hypersensitivity to cephradine or other cephalosporins.
* History of anaphylactic reactions to penicillins or other beta-lactam antibiotics (cross-reactivity is possible, though low).
## Adverse Effects
* **Common:** Diarrhea, nausea, vomiting, abdominal pain, oral candidiasis.
* **Serious:** *Clostridioides difficile*-associated diarrhea (CDAD), hypersensitivity reactions (rash, urticaria, anaphylaxis), neutropenia, elevated liver enzymes, interstitial nephritis.
## Key Drug Interactions
* **Probenecid:** Increases and prolongs serum levels of cephradine by decreasing renal tubular secretion.
* **Warfarin:** Cephalosporins may enhance the anticoagulant effect by disrupting gut flora that produce Vitamin K.
* **Live Vaccines (e.g., BCG, Typhoid):** Antibiotics may decrease the immunogenicity of live vaccines.
## Monitoring
* **Renal Function:** Serial monitoring of BUN and serum creatinine in patients with baseline renal impairment or those on high-dose, long-term therapy.
* **Clinical Efficacy:** Monitor for resolution of infectious symptoms.
* **Superinfection:** Monitor for signs of secondary fungal or resistant bacterial infections.
## Clinical Pearls
* **Administration:** Cephradine is unique among first-generation cephalosporins as it is available in both oral and parenteral forms.
* **Cross-Sensitivity:** Avoid in patients with a history of immediate hypersensitivity (anaphylaxis, angioedema) to penicillin.
* **Pregnancy/Lactation:** Generally considered safe (Category B), though use only if clearly indicated. Excreted in breast milk in small amounts; monitor infants for gastrointestinal disturbances or rash.
* **Consistency:** Take with food if GI upset occurs to improve tolerability.
