Since Lignogesic gel (lidocaine), Retoz (etoricoxib), and Chymoral BR (trypsin-chymotrypsin) are prescribed to manage pain, inflammation, and swelling, it is generally safe to stop using them once your symptoms have completely resolved. Unlike antibiotics, stopping these medications early will not cause harm. However, if any mild swelling or discomfort returns, you can resume them or consult your prescribing doctor to ensure your body has fully healed.
