Healthcare professionals may prescribe antibiotics such as ciprofloxacin or metronidazole when treating certain bacterial infections. These medications are effective in helping the body fight infections by stopping bacteria from growing. However, they work differently, and they\u2019re used for different types of infections. We\u2019ll review the safety and efficacy of using these two antibiotics together, discuss their potential side effects and interactions to be aware of, and outline important precautions to consider under the supervision of a healthcare provider.\u00a0<\/span><\/p>\n

Ciprofloxacin vs. metronidazole: Key differences<\/span><\/h2>\n

In order to understand why these drugs may be taken together and how to take them together, it may help to understand how they work. <\/span>Ciprofloxacin<\/span><\/a>, commonly called “cipro” is a broad-spectrum <\/span>antibiotic<\/span><\/a> that belongs to a class of medications called <\/span>fluoroquinolones (quinolones)<\/span><\/a>, which treat various bacterial infections, including respiratory, gastrointestinal, and urinary tract infections (UTIs). They also treat rare bacterial infections like typhoid fever, severe internal infections of the bones, joints, prostate, or abdomen, and pathogens used in bioterrorism attacks like anthrax or plague. Ciprofloxacin works by stopping the ability of bacterial cells to divide and repair themselves, effectively killing the bacteria and preventing them from growing in the body.<\/span><\/p>\n

Ciprofloxacin is available as tablets, extended-release tablets, and oral suspension (liquid). The usual adult dose is 250\u2013750 milligrams (mg) twice a day, depending on the infection.<\/span><\/p>\n

Metronidazole<\/span><\/a>, on the other hand, is both an antibiotic and an antiprotozoal medication that belongs to a class of medications called nitroimidazoles. It treats infections caused by anaerobic bacteria\u2014bacteria that grow and thrive in environments without oxygen. Metronidazole is commonly prescribed for conditions like <\/span>bacterial vaginosis<\/span><\/a>, <\/span>trichomoniasis<\/span><\/a>, lower respiratory tract infections, <\/span>rosacea<\/span><\/a>, pelvic inflammatory disease, and infections of the stomach or intestines. It works by breaking and damaging the DNA of bacteria and parasites, which kills them.<\/span><\/p>\n

Metronidazole is available in tablets, extended-release tablets, gel, cream, oral suspension, and injection. The typical adult dose is 500 mg every eight hours or 750 mg every 12 hours, depending on the infection.<\/span><\/p>\n

Can you take ciprofloxacin and metronidazole together?<\/span><\/h2>\n

Yes, ciprofloxacin and metronidazole can be taken together in certain situations, but this should always be done under the guidance of your healthcare provider. These antibiotics may be prescribed together for infections involving different types of bacteria. Examples include <\/span>diverticulitis<\/span><\/a>, <\/span>Crohn\u2019s disease<\/span><\/a>, and specific infections involving the teeth or gums.<\/span><\/p>\n

Using ciprofloxacin together with metronidazole may result in drug interaction that can increase the risk of irregular heart rhythms. This is a rare side effect; however, it can be serious and potentially life-threatening. If you have heart disease, a pre-existing heart condition called congenital long QT syndrome, or electrolyte disturbances (due to severe or prolonged diarrhea or vomiting), you may be more susceptible to this side effect.<\/span><\/p>\n

While taking these antibiotics together or on their own, talk with your healthcare professional or seek medical attention if you experience sudden dizziness, lightheadedness, shortness of breath, or heart palpitations (heart beating fast). Inform your healthcare provider about all other medications you are using, including vitamins and herbal supplements. Never stop taking any medications without first consulting your healthcare provider.<\/span><\/p>\n

Several studies have looked at using these antibiotics together:<\/span><\/p>\n

    \n
  1. A study published in the <\/span>Canadian Journal of Gastroenterology<\/span><\/i><\/a> examined the use of ciprofloxacin and metronidazole together to treat serious infections in the belly area. In the study, ciprofloxacin and metronidazole were reported to be well-tolerated. They seemed helpful in bringing about clinical remission for patients with active Crohn’s disease, especially when the colon is affected.<\/span><\/li>\n
  2. Another study published in <\/span>The Lancet Gastroenterology and Hepatology<\/span><\/i><\/a> found that giving oral antibiotics (ciprofloxacin and metronidazole) the day before colon surgery, as a preventive measure, significantly lowers the risk of surgical-site infections. This can be done without mechanical bowel preparation and should be routinely used before elective colon surgery.<\/span><\/li>\n<\/ol>\n

    Even though some studies suggest that ciprofloxacin and metronidazole can be used together, everyone\u2019s body reacts differently. What works for one person might not be the best option for another. Your healthcare provider will consider factors such as the following before prescribing both antibiotics:<\/span><\/p>\n
