How long does biphentin stay in the urine?

Biphentin, which contains the active ingredient methylphenidate, typically stays in the urine for about 1 to 2 days after use. However, this duration can vary based on factors such as metabolism, dosage, frequency of use, and individual health conditions. In some cases, it may be detectable for a longer period in chronic users. Always consult a healthcare professional for personalized information.
