Once I took Penegra 25 (sildenafil) to improve erection, can it affect my natural erectile function later?
No. Taking Penegra 25 (sildenafil) once does not damage your natural erectile function. The medicine only works while it is active in your body and does not cause permanent changes or dependence. If erection problems continue afterwards, they are usually due to underlying health or psychological issues, not the tablet itself.
