Ciprofloxacin Injection

• Type: Antibiotic

• Drug Class: Fluoroquinolone

• Form: Sterile solution for intravenous (IV) infusion

How It Works

• Ciprofloxacin works by inhibiting bacterial DNA gyrase and topoisomerase IV, enzymes essential for bacterial DNA replication.

• This stops bacterial growth and leads to bacterial death.

• It is a broad-spectrum antibiotic, effective against many gram-negative bacteria and some gram-positive bacteria.

Common Uses

Ciprofloxacin injection is used for moderate to severe bacterial infections, such as:

• Urinary tract infections (complicated and severe)

• Sepsis caused by gram-negative bacteria

• Respiratory tract infections (e.g., hospital-acquired pneumonia)

• Skin and soft tissue infections

• Bone and joint infections

• Intra-abdominal infections (often combined with metronidazole)

• Typhoid fever and gastrointestinal infections

• Anthrax exposure prophylaxis (IV form may be used in emergencies)

Advantages

• Rapid onset of action when given IV

• Good tissue penetration, including bones and joints

• Effective against many drug-resistant gram-negative bacteria

• Available as both oral and IV forms (allows step-down therapy from IV to oral)

Possible Side Effects

Most are mild but some can be serious:

• Nausea, vomiting, diarrhea

• Headache, dizziness

• Rash or allergic reaction

• Pain or swelling at IV site

• Rare but serious:

  • Tendon rupture or tendonitis (Achilles tendon most common)

  • Nerve problems (tingling, numbness – peripheral neuropathy)

  • Mood or mental changes (rare but reported)

  • Heart rhythm disturbances (QT prolongation in some patients)

Precautions

• Use with caution in patients with history of tendon disorders or on corticosteroids

• Avoid in children and pregnant women unless benefits outweigh risks (may affect growing cartilage)

• Adjust dose in patients with kidney problems

• Avoid unnecessary or prolonged use to prevent antibiotic resistance
