Ciprofloxacin is a generic drug. A generic drug is an exact copy of the active drug in a brand-name medication. Cipro is the brand-name medication that ciprofloxacin is based on. A generic is considered to be as safe and effective as the original drug. Generics tend to cost less than brand-name drugs.
If you’re interested in using Cipro instead of ciprofloxacin, talk with your doctor. They can tell you if Cipro comes in forms and strengths suitable for your condition. If you have insurance, you’ll also need to check whether your plan will cover Cipro.
To learn more about how generics compare with brand-name drugs, see this article.
The Food and Drug Administration (FDA) approves prescription drugs such as ciprofloxacin to treat certain conditions.
Ciprofloxacin is FDA-approved to treat urinary tract infections (UTIs) caused by certain bacteria. Specifically, the drug may be used to treat the following types of UTIs:
* Sex and gender exist on spectrums. Use of the term “female” in this article refers to sex assigned at birth.
UTIs are a type of infection that occur in your urinary tract. The urinary tract includes your bladder, kidneys, ureters, and urethra. Ureters are tubes that bring urine from your kidneys to your bladder. The urethra is the tube that brings urine from your bladder to the outside of your body.
UTIs that affect your bladder or urethra may be called bladder infections. Symptoms of bladder infections include:

The ciprofloxacin dosage your doctor prescribes will depend on several factors. These include:
The following information describes dosages that are commonly used or recommended. However, be sure to take the dosage your doctor prescribes for you. Your doctor will determine the best dosage to fit your needs.
Ciprofloxacin oral tablet is available in four strengths: 100 milligrams (mg), 250 mg, 500 mg, and 750 mg.
Below are the usual dosages of ciprofloxacin for each infection the drug is used to treat in adults.
When used to help prevent infections from inhaled anthrax, the usual dosage of ciprofloxacin is 500 mg every 12 hours. This dosage is typically continued for 60 days.
Below are the usual children’s dosages of ciprofloxacin. Each dosage is based on a child’s weight in kilograms (kg). One kg is about 2.2 pounds (lb).
For example, a 55-lb child weighs about 25 kg. To treat a kidney infection, the child’s dosage would be 250 mg every 12 hours. Your child’s doctor will determine what dosage is right for your child.
If you miss a dose of ciprofloxacin, check when your next dose is needed. If it’s at least 6 hours away, take your missed dose as soon as you remember. However, if it’s less than 6 hours away, skip your missed dose and take your next dose at its usual time.
You should not take any extra doses to make up for a missed dose. Taking extra doses can increase your risk of side effects.
To help make sure that you don’t miss a dose, try using a medication reminder. This can include setting an alarm or using a timer. You could also download a reminder app on your phone.
Ciprofloxacin is typically used as a short-term treatment. Your doctor can tell you how long treatment with ciprofloxacin typically lasts.
Here are answers to some frequently asked questions about ciprofloxacin.
Below are a few ways ciprofloxacin compares with the drugs ofloxacin and azithromycin.
Your doctor or pharmacist can tell you more about how these medications compare.
No, ciprofloxacin is not approved to treat tooth infections or strep throat.
However, the drug may be used off-label for these conditions. Off-label drug use is when a drug the Food and Drug Administration (FDA) has approved is prescribed for a purpose other than what it’s approved for.
If you have a tooth infection or strep throat, talk with your dentist or doctor. They can recommend the right treatment for your condition.
Yes, certain side effects of ciprofloxacin may continue even after you stop taking the drug.
For example, certain serious side effects may not go away after you stop taking ciprofloxacin. These include tendon problems, nerve problems, and central nervous system effects. In fact, ciprofloxacin has a boxed warning for these side effects. This is a serious warning from the FDA. To learn more, see the “Ciprofloxacin precautions” section below.
If you have questions about what to expect after stopping ciprofloxacin treatment, talk with your doctor.
No, ciprofloxacin does not come as 1,000-milligram (mg) tablets. Ciprofloxacin is available in the following forms:
In the past, an extended-release (ER) oral tablet form of ciprofloxacin was available in two strengths: 500 mg and 1,000 mg. However, these ER forms have been discontinued.
Your doctor and pharmacist can help answer additional questions you have about the forms of ciprofloxacin and which one is right for you.
* This form of ciprofloxacin can be given by a healthcare professional in a hospital or clinic. The typical dose for IV ciprofloxacin is 400 mg.
The half-life of ciprofloxacin is 4 hours.
A drug’s half-life is the amount of time it takes the body to eliminate half of a drug’s dose. This means it takes about 4 hours for your body to get rid of half a dose of ciprofloxacin.
It takes about five half-lives for a drug to leave your system entirely. For ciprofloxacin, this means the drug stays in your system for about 20 hours.
If you have other questions about the half-life of ciprofloxacin, ask your doctor or pharmacist.
Ciprofloxacin can interact with several other medications. It can also interact with certain supplements as well as certain foods.
Different interactions can cause different effects. For instance, some interactions can interfere with how well a drug works. Other interactions can increase side effects or make them more severe. Drug-condition interactions can also cause certain effects. For information about these interactions, see the “Ciprofloxacin precautions” section below.
Before taking ciprofloxacin, talk with your doctor and pharmacist. Tell them about all prescription, over-the-counter, and other drugs you take. Also, tell them about any vitamins, herbs, and supplements you use. Sharing this information can help you avoid potential interactions.
Below is a table of medications that can interact with ciprofloxacin. This table does not contain all drugs that may interact with ciprofloxacin.
* The interaction pertains to dexamethasone that’s that is for systemic use. (Systemic treatments affect the whole body.) An ear drop containing ciprofloxacin/dexamethasone (Ciprodex) is also available.

Other types of interactions, such as those with herbs, supplements, foods, lab tests, and vaccines, may also occur with ciprofloxacin. The following table lists some of these interactions.
Your doctor can provide you with details about these interactions with ciprofloxacin.
There’s no known interaction between ciprofloxacin and alcohol.
However, drinking alcohol while taking ciprofloxacin could worsen some of the drug’s side effects. Examples include digestive problems, such as nausea and vomiting.
If you drink alcohol, talk with your doctor before taking ciprofloxacin. They can advise you on whether you should limit the amount of alcohol you consume while taking the drug.
Below is important information about taking ciprofloxacin while pregnant or breastfeeding.
It’s not known for certain whether ciprofloxacin is safe to take while pregnant. However, reports of the drug’s use in pregnancy have not shown any harm to a pregnant person or fetus.
If you’re pregnant or planning a pregnancy, talk with your doctor before taking ciprofloxacin. They’ll recommend whether the medication is a safe treatment option for you during pregnancy.
It may not be safe to take ciprofloxacin while breastfeeding. The drug passes into breast milk, which may lead to side effects in a child who is breastfed.
For this reason, it’s recommended to avoid breastfeeding while you’re taking ciprofloxacin and for at least 2 days after your last dose.
If you’re breastfeeding or planning to do so, talk with your doctor before starting ciprofloxacin treatment. They can advise you on other ways to feed your child while you’re taking the drug.
It’s not known whether ciprofloxacin is safe to take during pregnancy. If you’re sexually active and you or your partner can become pregnant, talk with your doctor about your birth control needs while you’re using ciprofloxacin.

You may wonder how ciprofloxacin compares with other medications prescribed for similar uses. Ciprofloxacin is a generic drug. It’s available as the brand-name drug Cipro. To find out how Cipro is similar to and different from levofloxacin and other drugs, see this article.
You should take ciprofloxacin according to the instructions your doctor gives you.
Ciprofloxacin comes as an oral tablet that you swallow.
When used to treat certain abdominal infections, ciprofloxacin is prescribed in combination with metronidazole (Flagyl). This is because ciprofloxacin treats certain bacteria that cause abdominal infections, while metronidazole treats different bacteria.
For ciprofloxacin’s other uses, your doctor will let you know whether you should take the drug by itself or with other treatments.
For most uses, you’ll likely take ciprofloxacin twice per day.* You should take each dose at least 12 hours apart.
Taking the medication around the same time of day helps keep a steady level of the drug in your body. This helps ciprofloxacin work effectively.
To help make sure that you don’t miss a dose, try using a medication reminder. This can include setting an alarm or using a timer. You could also download a reminder app on your phone.
* For gonorrhea, you’ll usually take just one dose of ciprofloxacin.
If your prescription label is hard to read, talk with your doctor or pharmacist. Some pharmacies offer labels that have large print, braille, or a code you scan with a smartphone to convert text to speech. If your local pharmacy doesn’t have these options, your doctor or pharmacist may be able to direct you to one that does.
If you have trouble opening medication bottles, ask your pharmacist if they can put ciprofloxacin in an easy-open container. They also may be able to recommend tools that can make it simpler to open lids.
You can take ciprofloxacin with or without food.
Some people have digestive side effects from ciprofloxacin. Examples include nausea, vomiting, and diarrhea. If you have digestive side effects, taking the drug with food may help ease your symptoms.
Keep in mind that certain foods and drinks can reduce the level of ciprofloxacin in your body. This includes dairy products, such as milk and yogurt, and juices that contain calcium. Having a lower level of ciprofloxacin in your system could make the drug less effective than usual for helping your condition.
For this reason, you should take ciprofloxacin at least 2 hours before or 6 hours after consuming any dairy products or juices that contain calcium. Doing so should help prevent these foods and drinks from affecting the level of ciprofloxacin in your body.
You should not crush, split, or chew ciprofloxacin oral tablets. You should swallow the tablets whole.
If you have trouble swallowing ciprofloxacin tablets, talk with your doctor or pharmacist.
As with all medications, the cost of ciprofloxacin can vary. The actual price you’ll pay for 100-milligram (mg), 250-mg, 500-mg, and 750-mg ciprofloxacin oral tablets depends on different factors. These include your insurance plan, your location, and the pharmacy you use.
Before approving coverage for ciprofloxacin, your insurance company may require you to get prior authorization. This means that your doctor and insurance company will need to communicate about your prescription before the insurance company will cover the drug. The insurance company will review the prior authorization request and decide if the drug will be covered.
If you’re not sure if you’ll need to get prior authorization for ciprofloxacin, contact your insurance company.
Financial assistance to help you pay for ciprofloxacin may be available.
Medicine Assistance Tool and NeedyMeds are two websites offering resources that may help decrease the price you pay for ciprofloxacin. They also offer tools to help you find low cost healthcare, as well as educational resources. To learn more, visit their sites.

If you don’t have insurance, you can ask your doctor or pharmacist about online pharmacy options.
This drug comes with several precautions. These are considered drug-condition interactions.
This drug has boxed warnings. A boxed warning is the most serious warning from the Food and Drug Administration (FDA). It alerts doctors and patients about drug effects that may be dangerous.
Worsening of myasthenia gravis. Fluoroquinolone antibiotics, including ciprofloxacin, may worsen the rare condition myasthenia gravis in people who already have it. (Myasthenia gravis causes muscle fatigue and weakness.)
Rarely, taking fluoroquinolones can lead to the need for a ventilator and, in certain instances, be fatal for people with myasthenia gravis. Due to this risk, doctors are not likely to prescribe ciprofloxacin if you have the condition. Your doctor can recommend a different treatment option for you.
Serious side effects such as tendon problems, nerve problems, and central nervous system effects. Fluoroquinolone antibiotics, including ciprofloxacin, may cause certain serious side effects. These include:
Before taking ciprofloxacin, be sure to tell your doctor if you have tendon problems. Also, tell them if you’ve had a heart, kidney, or lung transplant, or take corticosteroids. And be sure your doctor knows whether you’re older than age 60 years. These factors can increase your risk of tendon problems with ciprofloxacin.
If you’ve had any of the above side effects while taking ciprofloxacin in the past, your doctor likely will not prescribe this drug for you. They’ll advise you on a different treatment option for your condition.
If you have the side effects above while taking ciprofloxacin, tell your doctor as soon as possible. They’ll likely recommend that you stop taking the medication. In some cases, serious side effects from ciprofloxacin may not go away after you stop taking the drug. Your doctor can advise you on how to manage these side effects if they occur.
In addition to the boxed warnings mentioned above, ciprofloxacin has other warnings.
If any of the following medical conditions or other health factors pertain to you, be sure to talk with your doctor before taking ciprofloxacin.
Note: For more information about the potential negative effects of ciprofloxacin, see the “Ciprofloxacin side effects” section above.

When you get ciprofloxacin from the pharmacy, the pharmacist will add an expiration date to the label on the bottle. This date is typically 1 year from the date they dispensed the medication.
The expiration date helps guarantee that the medication is effective during this time. The current stance of the Food and Drug Administration (FDA) is to avoid using expired medications. If you have unused medication that has passed the expiration date, talk with your pharmacist about whether you can still use it.
How long a medication remains good can depend on many factors, including how and where you store the medication.
You should store ciprofloxacin tablets at a room temperature of 68°F to 77°F (20°C to 25°C). You can temporarily store the tablets at a temperature of 59°F to 86°F (15°C to 30°C), such as while traveling. Be sure to store the drug in a tightly sealed container, avoiding areas where it could get damp or wet, such as bathrooms.
If you no longer need to take ciprofloxacin and have leftover medication, it’s important to dispose of it safely. This helps prevent others, including children and pets, from taking the drug by accident. It also helps keep the drug from harming the environment.
This article provides several useful tips on medication disposal. You can also ask your pharmacist for information about how to dispose of your medication.
Do not take more ciprofloxacin than your doctor recommends. For some drugs, doing so may lead to unwanted side effects or overdose.
If you think you’ve taken too much of this drug, call your doctor. You can also call the American Association of Poison Control Centers at 800-222-1222 or use its online tool.
