Ciprofloxacin (CIPRO)

What Is Ciprofloxacin?

Ciprofloxacin is an antibiotic that belongs to the Fluoroquinolone group, which is used to treat various bacterial infections affecting many parts of the body. It treats infection by preventing bacteria from replicating and growing. It is prescribed for uncomplicated urinary tract infection (UTI). It is also used for infections of the bone, abdomen, skin, and prostate.

Ciprofloxacin is available in infusion solution, oral suspension, tablet, extended-release tablet, eye drops, and ear drops.

What Does Ciprofloxacin Treat?

It is used in treating the following infections:

  • Gastroenteritis.

  • Bone and joint infection.

  • Food poisoning.

  • Pneumonia.

  • Bronchitis.

  • Gonorrhea.

  • Sinusitis.

  • Cellulitis.

  • Urinary tract infection.

  • Gallbladder infection.

  • Ear infection.

  • Eye infection.

Apart from these infections, it is also used to prevent and treat pneumonic and septicemic plague. It does not cure syphilis, but can be used to delay the symptoms. For sinusitis, bronchitis, and UTI, Ciprofloxacin is only prescribed if other antibiotics fail, as the risk of side effects is higher.

How Does Ciprofloxacin Work?

Ciprofloxacin is a broad-spectrum antibiotic, that is, it is effective against various types of bacterial infection. It is bactericidal, which means, it kills bacteria by blocking enzymes needed for bacteria to divide and grow. But due to indiscriminate use, many bacteria have become resistant to Ciprofloxacin.

How Long Does Ciprofloxacin Take to Work?

It starts working within an hour of taking orally. But, it might take a few days for the infection to go down and for you to see improvement.

Around 40 to 50 % of Ciprofloxacin is excreted through the urine unchanged, and it is completed excreted from the body within 24 hours. The half-life (time taken for the drug concentration to be 50 %) is 4 to 5 hours.

What Is the Dosage for Ciprofloxacin?

Your doctor will prescribe Ciprofloxacin based on the type and severity of bacterial infection, your age, and kidney or other underlying diseases. Always take this medicine under strict medical supervision, and do not take higher doses than prescribed.

Ciprofloxacin is available in the following strengths and forms:

  • Tablet - 100 mg, 250 mg, 500 mg, and 750 mg.

  • Extended-release tablet - 500 and 1000 mg.

  • Infusion solution - 200 mg/100 mL, 200 mg/20 mL, 400 mg/ 40 mL, and 400 mg/ 200 mL.

  • Oral suspension - 250 and 500 mg/mL.

The commonly recommended dosages for adults are:

  • For mild to moderate infection - 250 to 500 mg orally every 12 hours for 7 to 14 days.

  • For severe infection - 500 to 750 mg orally every 12 hours for 7 to 14 days.

For some chronic infections, it is prescribed for a more extended period. For patients with kidney impairment, this medicine is used in a lower dosage.

How to Use Ciprofloxacin?

Use it as directed by your physician. Ciprofloxacin is usually taken every 12 hours (twice a day), with or without food. Depending on how severe the infection is, you might have to take it for a week or more. Continue taking it even if you feel your symptoms have disappeared, and take it for the prescribed number of days. The infection might return if you stop the medicine in the middle.

The extended-release tablet should not be crushed or broken and should be swallowed as a whole. And oral suspension should be properly shaken before taking.

Avoid taking medicines or supplements (like Quinapril, Sucralfate, iron and zinc supplements, Sevelamer) 2 hours before or 6 hours after taking Ciprofloxacin, as it can interact and increase or decrease its effectiveness. Milk and other milk products that are rich in calcium can reduce the effect of Ciprofloxacin.

What to Do If You Miss a Dose of Ciprofloxacin?

To avoid missing a dose, always take the tablet at the same time every day, so that you will form a habit. But because of any reason you forget a dose, take it as soon as you remember. If it is already time for the next dose, skip the missed dose as it is not advisable to take two doses at the same time. It might result in dangerous side effects.
