Cipro (ciprofloxacin): what it is and when it helps

Cipro is the brand name for ciprofloxacin, a commonly used antibiotic. Doctors prescribe it for many bacterial infections — urinary tract infections, some types of bronchitis, certain stomach infections, and more. It kills bacteria by stopping them from copying their DNA, which makes it useful for infections caused by susceptible bugs.

How Cipro is usually taken and dosing basics

Adults typically take Cipro as a tablet or liquid, often twice a day. Doses vary by infection: lower doses for simple UTIs, higher doses for serious infections. Treatment length can be a few days to a few weeks depending on the problem. Always follow the exact dose and schedule your prescriber gives you. Don’t stop early even if you feel better — stopping can let the infection come back or breed resistant bacteria.

Take Cipro with a full glass of water. Food is okay with Cipro, but avoid dairy or calcium-fortified drinks right around the dose — they can reduce how much drug your body absorbs. Also separate Cipro from antacids, calcium, iron, zinc, or sucralfate by at least 2–6 hours.

Common side effects and serious warnings

Expect possible mild side effects like nausea, diarrhea, headache, or dizziness. Most people tolerate it fine, but some effects need quick action. Cipro can cause tendon irritation or even tendon rupture — if you get sudden tendon pain, stop the drug and call a doctor. It can also increase sensitivity to the sun, so use sunscreen and avoid long sun exposure.

Serious but rare problems include severe allergic reactions, worsening muscle weakness in people with myasthenia gravis, and mental changes like confusion or hallucinations. If you have severe diarrhea (especially bloody), a rash, swelling, breathing trouble, or new weakness, seek medical care immediately.

Drug interactions matter. Cipro can raise levels of warfarin and theophylline; it also interacts with certain heart rhythm drugs. Tell your doctor about all medicines, vitamins, and supplements you take, especially antacids and blood thinners.

A note on special groups: Cipro is usually avoided in pregnancy and children because of potential effects on growing cartilage, unless the benefit outweighs the risk. Kidney function affects dosing — your provider may lower the dose if your kidneys don’t work well.

Antibiotic safety tip: only use Cipro when prescribed for a confirmed or strongly suspected bacterial infection. Using antibiotics when they aren’t needed helps resistant bacteria spread.

Quick checklist before you start Cipro: tell your provider about allergies, past tendon problems, pregnancy or breastfeeding, current meds (especially antacids and blood thinners), and kidney disease. Ask how long you should take it and what to watch for.
