Product introduction

Opiprex 100mg Tablet may be taken with or without food. However, it is advised to take it at a fixed time each day to maintain a consistent level of medicine in the blood. If you have missed a dose, take it as soon as you remember and finish the full course of treatment even if you feel better. This medication must not be stopped suddenly without talking to your doctor, as it may worsen your symptoms.

Some common side effects of this medicine include nasal congestion, fatigue, and dryness in the mouth.
