She hopes that it will lead to hypotheses about what might mitigate harms that could then be tested in clinical trials.

But little support is available. She cites a list made by the pharmaceutical firm Merck of doctors who criticized the anti-inflammatory drug Vioxx rofecoxib , which was withdrawn from the market over an increased risk of heart attack and stroke. For Osheroff, there are more-pressing concerns about fluoroquinolones, such as how to combat the emergence of antibiotic-resistant infections and develop new antibiotics.

But he and other scientists agree that doctors should not prescribe fluoroquinolones for relatively minor infections when they could use other drugs. The labels for fluoroquinolones alone have changed around 20 times in the past 4 or 5 years, he says.

Some people who take Cipro get headaches. In clinical studies, less than 1 percent of people had headaches while taking Cipro. These headaches are usually mild and may go away with continued use of the drug. Vaginal yeast infections can sometimes occur after treatment with antibiotics, including Cipro.

Cipro use is typically avoided in children because it might cause joint damage in children. Symptoms of joint damage in children can include reduced joint movement and joint pain. If your child is taking Cipro and has these symptoms, call their doctor right away.

Older adults are more likely than younger adults to have side effects from Cipro. However, the types of side effects they have are the same as those in younger adults. Cipro is FDA-approved for treating many different types of infections in adults. Examples of these FDA-approved uses include:. Although Cipro is effective, the FDA has recommended that Cipro and other fluoroquinolone antibiotics should not be used as a first-choice antibiotic for certain infections, such as:.

For these conditions, the risk of serious side effects caused by Cipro outweigh the benefits. Other antibiotics should be used as a first choice. Cipro is also sometimes used off-label for uses that are not approved by the FDA. Examples of these include:. The generic version of Cipro is approved to treat all of the conditions that Cipro is approved for. In addition to those conditions, ciprofloxacin is approved to treat ear infections.

Cipro is FDA-approved for use in children to treat certain infections, such as severe urinary tract infection. However, Cipro is not the first choice for use in children due to concerns that it may cause joint damage in children. Cipro is an antibiotic in the class of fluoroquinolones.

This type of antibiotic is bactericidal. This means that it directly kills bacteria. It does this by blocking enzymes that are needed for bacteria survival. Cipro is a broad-spectrum antibiotic. This means it works against many different types of bacteria. However, many bacteria have grown to be resistant to Cipro. Resistant bacteria can no longer be treated with a certain drug.

Cipro begins to work against bacterial infections within hours of when you take it. However, you may not notice improvement in your symptoms for a few days. 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 suit your needs. The typical dosage for immediate-release Cipro is — mg every 12 hours for up to 14 days. Your doctor will determine the best form and dosage of Cipro for your condition. If you have kidney disease, your doctor may prescribe Cipro at a lower dose or have you take the medication less frequently.

If you miss a dose, take it as soon as you can. You might start to feel better before you finish your entire Cipro treatment. Cipro tablets and suspension should be taken at about the same time each day in the morning and the evening. Cipro can be taken with or without food. Either way you take it, be sure to consume plenty of fluids while taking Cipro.

It should be taken at least two hours before or after consuming these products. However, Cipro can be taken along with a meal that contains dairy products or calcium-fortified foods or drinks. Cipro tablets and Cipro XR extended-release tablets should not be crushed, split, or chewed. They should be swallowed whole. Cipro 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 can interfere with how well a drug works, while others can cause increased side effects. Below is a list of medications that can interact with Cipro. This list does not contain all drugs that may interact with Cipro. Before taking Cipro, be sure to tell your doctor and pharmacist 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. If you have questions about drug interactions that may affect you, ask your doctor or pharmacist.

Many antacids such as Tums, Gaviscon, and Maalox contain calcium carbonate, magnesium hydroxide, and aluminum hydroxide. These ingredients can bind to Cipro and prevent your body from absorbing it. This can decrease how well Cipro works. To avoid this interaction, take Cipro at least two hours before taking an antacid, or six hours afterward. Taking Cipro with oral anticoagulant drugs such as warfarin Coumadin, Jantoven might increase the anticoagulant effects.

This might result in increased bleeding. If you take an anticoagulant, your doctor may need to monitor your bleeding risk more frequently if you take Cipro. Certain medications prolong your QT interval, which means they might affect the rhythm of your heartbeat. Taking Cipro with these drugs can increase the risk of having a dangerous irregular heartbeat. Cipro should be avoided or used very carefully with these medications. Taking Cipro with clozapine Versacloz, Fazaclo ODT can increase the levels of clozapine in the body and increase the risk of clozapine side effects.

Cipro can increase the blood sugar-lowering effects of certain diabetes drugs, such as glyburide Diabeta, Glynase PresTabs and glimepiride Amaryl. This might cause blood sugar levels to become too low.

Taking Cipro with methotrexate Rasuvo, Otrexup can increase the levels of methotrexate in your body and increase the risk of methotrexate side effects.

Taking Cipro with ropinirole Requip, Requip XL can increase the levels of ropinirole in the body and increase the risk of ropinirole side effects. Taking Cipro with the seizure drug phenytoin Dilantin, Dilantin, Phenytek can cause phenytoin levels in the body to become too low. This can result in uncontrolled seizures in people taking phenytoin for epilepsy. Taking Cipro with sildenafil Viagra , Revatio can increase the levels of sildenafil in your body and increase the risk of sildenafil side effects.

Taking Cipro with theophylline can increase levels of theophylline in your body. This can cause serious theophylline side effects. These include nausea, vomiting, jitters, irritability, abnormal heartbeat, heart attack, seizures, and breathing failure. Cipro and theophylline should not be taken together if possible. Cipro can increase the sedative and blood pressure effects of tizanidine Zanaflex. This might result in excessive sedation from zolpidem.

Cipro can prolong your QT interval, which means it might affect the rhythm of your heartbeat. Using these drugs together might increase the risk of a dangerous irregular heartbeat. Some vitamin and supplement products can bind to Cipro and prevent your body from absorbing it.

These supplements include:. To avoid this interaction, you should take Cipro at least two hours before you take these supplements, or at least six hours afterward. Dairy foods or calcium-fortified juice can bind to Cipro and prevent your body from absorbing it. To avoid this interaction, you should take Cipro at least two hours before you consume these foods, or at least two hours afterward.
