Ciprofloxacin

Ciprofloxacin is a prescription antibiotic used to treat various bacterial infections in adults. It belongs to the fluoroquinolone class and is often reserved for infections that do not respond to other, safer antibiotics. At WellMed Bangkok Clinic, ciprofloxacin is prescribed cautiously by our physicians to ensure maximum benefit with minimal risk.

Ciprofloxacin is a fluoroquinolone antibiotic used for the treatment of moderate to severe bacterial infections. It works by inhibiting enzymes needed for bacterial DNA replication, effectively stopping bacterial growth and leading to their elimination from the body.

It may be prescribed to treat:

• Urinary tract infections (UTIs)

• Respiratory infections such as bronchitis or pneumonia

• Prostatitis (prostate infections)

• Skin, bone, and joint infections

• Gastrointestinal tract infections

• Anthrax exposure (post-exposure prophylaxis)

• Plague and certain sexually transmitted infections

Due to its potency and risk profile, ciprofloxacin is typically not the first-line treatment and is reserved for when other antibiotics are ineffective.

How It Works

Ciprofloxacin interferes with the bacteria’s ability to reproduce by targeting the enzymes DNA gyrase and topoisomerase IV, both critical to bacterial cell division. This results in bacterial death and infection control.

It has no effect on viral infections such as the flu or common cold.

Who Should Use It?

Ciprofloxacin is suitable for adults (and occasionally children in specific cases) who have:

• Serious or resistant bacterial infections

• Conditions requiring a broad-spectrum antibiotic

• Previously failed other treatments

It should only be used when prescribed by a doctor and after weighing the potential benefits against known risks.

Safety Information

• Contraindications: Not recommended for individuals with a history of tendon disorders related to fluoroquinolones, or for patients on tizanidine.

• Drug Interactions: May interact with antacids, corticosteroids, blood thinners, and caffeine.

• Side Effects: Common side effects include nausea, diarrhea, dizziness, and restlessness. Serious but rare effects include tendon rupture, nerve damage, or mood changes.

• Precautions: Use with caution in the elderly, people with kidney disease, or those with a history of seizures. Avoid excessive sunlight or UV exposure during treatment.
