In brief: Dose
At small doses, not really many.
At toxic doses, can see seizure or heart arrythmia. A careful practitioner can use this drug very safely and effectively and recognize signs of trouble early. Other side effects depend on area being blocked or additives (epinephrine, preservative).

In brief: Few side effects
When Lidocaine is injected into an area (such as around a tooth) to numb it, there are usually no side effects.
If Epinephrine is added to lidocaine, it may cause a rapid heart beat or a rise in blood pressure. If Lidocaine is given IV to treat an abnormal heart rhythm, it may briefly cause ringing in the ears or a feeling of dizziness.
