Is it possible that Nitroxolin Forte used for prostatitis only worked after 16 days?

Usually, the symptoms disappear in the first days of treatment. Nevertheless, the response to treatment is individual, so it is possible that in your case the improvement occurred only after 16 days and this is due to the antibiotic. As research shows: "The treatment of prostatitis must be tailored to the etiology and nature of the disease, but also to the patient's expectations. If we are dealing with bacterial prostatitis, about 6-8 weeks of antibiotic therapy is used, combined with anti-inflammatory and analgesic treatment (in suppositories or tablets), and in older men – also with the use of drugs that improve the outflow of urine from the bladder. If the therapy does not bring the expected results, more or less invasive procedures may be performed, e.g. Botox injection of the prostate gland or thermotherapy of the prostate gland (TUMT). In the case of chronic pelvic pain syndrome, antibiotic therapy is also used, but – depending on the individual case – the use of anti-inflammatory drugs, muscle tension relaxants or antidepressants may be recommended. A broadly understood lifestyle change can also be helpful in reducing ailments: compliance with the principle of a healthy diet, physical activity, as well as physiotherapy and psychological therapy." Therefore, you should observe your body, and in the event of a recurrence of symptoms, consult a doctor. More here: https://www.gdziepolek.pl/artykuly/jak-wyleczyc-chora-prostate
