Waiting for 30 minutes after using viscous lidocaine before eating is important to allow the medication time to numb the affected area and prevent accidental bites or burns. It is also important to avoid eating or drinking hot or spicy foods or beverages during this time as this can cause further irritation. While cleansing the oral cavity and using the medication as a gargle can be important steps in treatment, waiting 30 minutes before eating is the most crucial instruction to follow with this medication. Diminished sense of taste may also occur, but this is not as important as waiting before eating.
