Step-by-step explanation:
The recommended length of time to use phenazopyradine as part of the treatment for UTI can vary depending on the severity of the infection and the individual's response to the medication. Typically, phenazopyradine is used as a short-term treatment for the relief of symptoms such as pain, burning, and urgency associated with UTI. It is not used to treat the underlying infection itself, but rather to provide symptomatic relief while antibiotics are used to address the infection.
It is important to note that phenazopyradine should not be used for more than two days without consulting a healthcare professional. If symptoms persist or worsen, it is important to seek medical advice for further evaluation and appropriate treatment.
