Nervup PG (containing Pregabalin) is effective for nerve pain, but it often takes 2 to 4 weeks to show full benefits. Do not stop taking this medicine abruptly, as sudden discontinuation can cause withdrawal symptoms. If your pain has not improved, your doctor may need to increase the dosage or investigate the root cause, such as a pinched nerve in your lower back. While alternative medications like Gabapentin or Duloxetine are available, you should consult your prescribing physician before making any changes to safely evaluate and adjust your treatment plan.
