Taking ciprofloxacin for strep throat will generally be effective but is not always the best treatment option. The chemical action of ciprofloxacin, which is sometimes known as cipro, does work against the variety of bacteria that causes strep throat. Some bacterial populations, however, may have mutated and become resistant to this antibiotic. Other antibiotics are commonly used before ciprofloxacin, both because of the need to limit the development of drug resistance and because of the side effects of ciprofloxacin, which can be quite serious.

Ciprofloxacin is an antibiotic and is effective against a wide variety of different bacterial infections. Like all antibiotics, it does nothing to combat a viral infection. It works by interfering with some of the chemicals that many types of bacteria need in order to develop and reproduce. This drug will typically kill or weaken a large percentage of a bacterial population, and the body's immune system can then generally handle any surviving bacteria.


The variety of streptococcus bacteria that is responsible for strep throat is normally susceptible to treatment with ciprofloxacin. This drug will normally be prescribed for seven to ten days and is typically taken twice daily. It is important to space doses of this drug at even 12 hour intervals, because this will maintain a steady and effective level of antibiotics in the bloodstream. If the concentration of ciprofloxacin or any other antibiotic drops too low, then bacteria populations may be able to recover, which can lead to the development of resistant strains?

Penicillin and other antibiotics are often prescribed instead of ciprofloxacin for strep throat. This is because the bacteria that cause strep throat often respond to other antibiotics just as effectively and because the side effects of ciprofloxacin can be more serious than those associated with some other antibiotics. Cipro interacts with several other medications, and some patients will not be able to take it if they have had negative reactions to the class of antibiotics that it belongs to.

In a small number of cases, taking ciprofloxacin for strep throat may prove to be ineffective due to bacterial resistance. This is fairly uncommon because bacteria need to undergo a rather complicated mutation in order to develop such immunity, but it is not unheard of. If this drug is ineffective due to bacterial immunity, then some other antibiotic will typically be used instead. More powerful and newer antibiotic drugs often produce even more serious side effects.

Fluoroquinelones do not work well for upper side respiratory problems. Better try Cephalosporins for those problems, or Amoxocilin or any other class of penicillin. Cephradines work best for me.

I've had a couple of urinary tract infections and cipro worked very well for them. Now I've been prescribed it for an ear and strep throat infection, and so far it hasn't worked. I'm going to give it a couple more days then back to med express.

My doctor's favorite drug to prescribe for just about any condition is ciprofloxacin. The funny thing is that it seems to clear up every infection that I get, too!

It worked on my strep infection, but it did have help from that steroid shot and steroid dose pack. I have a feeling that the steroids are what caused me to feel better right away, and the ciprofloxacin is what slowly cleared up the infection.

Ciprofloxacin makes everything I put in my mouth taste horribly bitter. I can't even drink water without getting that unpleasant taste while I'm on it.

I was glad that my doctor gave me penicillin instead of ciprofloxacin last winter when I got strep throat. I could have taken ciprofloxacin, but I really would have been miserable if I had, because I wouldn't have been able to enjoy any food or anything that I drank during that time.

@wavy58 – Amoxicillin seems to be a popular drug to treat strep. My mother took it for this once, and I have taken it twice. It cleared up my infection nicely, but my mother couldn't stand to take it for long enough.

She said that it made her vomit. So, she got the doctor to give her something else, and he gave her ciprofloxacin. It didn't cause any bad side effects, and she recovered quickly.

My dad gets extremely nauseous if he takes ciprofloxacin. He always asks his doctor to give him something else if this drug is what he is about to prescribe.

Though he has taken it for some types of infection, I don't think he's ever had to take it for strep throat. I remember him taking amoxicillin for that once, and he got better in just a short time.
