Reviews

We picked up some reviews of people who used Norfloxacin:

Irina. I used this medicine recently as soon as I got cystitis. Saw 2 tablets 2 times a day. The course is 3 days. The result is very satisfied, because I did not take anything else. Even the probiotics forgot to drink, there was no frustration. Then she advised my mother when she also had such a problem. I advise, an effective drug!
Martha. While I drink norfloklatsin 2 weeks, the bacteria disappear in the urine, stop, the bacteria reappear. Probably longer it is necessary to drink. The urologist says that she did not recover.
Novel. A good enough antibiotic, as for me. There are contraindications, but they did not manifest themselves to me. I took it without a doctor's prescription in severe cases, when it was necessary to recover very quickly after a cold or to cure a throat with a sore throat. The drug is relatively well tolerated by the body, in rare cases there may be drowsiness. At admission I recommend to refuse works requiring higher concentration. Dysbacteriosis was not observed. If that bothers you, then you can take either cetrin or diazolin. External allergic manifestations also did not observe. At reception I recommend to adhere to the norms specified in the instruction and not to exceed them.
