# Ciproxin (ciprofloxacin)
## Overview
Ciprofloxacin is a broad-spectrum fluoroquinolone antibiotic effective against many Gram-positive and Gram-negative bacteria.
## Primary Indications
* Urinary tract infections (UTIs)
* Prostatitis
* Gastroenteritis caused by susceptible organisms (e.g., Shigella, Salmonella)
* Bone and joint infections
* Intra-abdominal infections
* Respiratory tract infections (select agents)
* Skin and soft tissue infections
* Inhalational anthrax (treatment and prophylaxis)
* Typhoid fever
## Adult Dosing
Dosing varies significantly by indication and severity. Common examples:
* **Complicated UTI:** 500 mg orally every 12 hours for 7-14 days or 400 mg IV every 8-12 hours for 7-14 days.
* **Uncomplicated UTI:** 250 mg orally every 12 hours for 3 days.
* **Inhalational Anthrax (treatment):** 500 mg orally or IV every 12 hours for 60 days.
* **Maximum dose:** Generally 1500 mg orally per day or 1200 mg IV per day.
## Pediatric Dosing
Used in pediatric patients for specific indications when benefits outweigh risks, such as complicated UTIs or inhalational anthrax. Dosing is based on weight.
* **Complicated UTI (ages 1 to 17):** 10 mg/kg orally every 12 hours or 10-15 mg/kg IV every 8 hours. Maximum dose 500 mg orally or 400 mg IV per dose.
* **Inhalational Anthrax (children > 1 year):** 10-15 mg/kg IV every 8 hours or 10 mg/kg orally every 12 hours. Dosing should not exceed adult maximums.
## Dose Adjustments
* **Renal Impairment:** Reduce dose in moderate to severe renal impairment (CrCl < 30 mL/min). Consult specific guidelines or product labeling for precise adjustments.
* **Hepatic Impairment:** No dose adjustment typically required.
## Contraindications
* Hypersensitivity to ciprofloxacin, other fluoroquinolones, or any component of the formulation.
* Concomitant use with tizanidine.
## Adverse Effects
* **Common:** Nausea, vomiting, diarrhea, abdominal pain, rash, headache, dizziness.
* **Serious:** Tendon rupture (especially Achilles), peripheral neuropathy, central nervous system effects (seizures, hallucinations, suicidal ideation), *Clostridioides difficile*-associated diarrhea, QT interval prolongation, phototoxicity, dysglycemia (hypo- and hyperglycemia), aortic aneurysm/dissection.
## Key Drug Interactions
* **Tizanidine:** Increased tizanidine levels and severe hypotension. Contraindicated.
* **Theophylline:** Increased theophylline levels. Monitor and adjust theophylline dose.
* **Warfarin:** May potentiate anticoagulant effect. Monitor INR closely.
* **Antacids, Sucralfate, iron supplements, calcium supplements, multivitamin with zinc:** Oral absorption reduced. Separate administration by at least 2 hours before or 6 hours after.
* **Probenecid:** May increase ciprofloxacin levels.
* **CYP1A2 substrates:** Ciprofloxacin can inhibit CYP1A2, increasing levels of drugs like clozapine and duloxetine.
## Monitoring
* Renal function (especially with dose adjustment).
* Signs and symptoms of tendon inflammation or rupture.
* Neurological status.
* Blood glucose levels, particularly in diabetic patients.
* INR if co-administered with warfarin.
* Electrolytes and ECG for QT prolongation risk.
## Clinical Pearls
* Administer oral suspensions and tablets at least 2 hours before or 6 hours after cation-containing antacids, iron, calcium, and zinc.
* Adequate hydration is important to prevent crystalluria.
* Discontinue immediately if tendon pain or swelling occurs.
* Use with caution in patients with known QT prolongation risk factors or on other QT-prolonging medications.
* Consider the risk of dysglycemia and monitor blood glucose, especially in diabetic patients.
