If pure local anesthesia is all that was used, one shouldn't feel drowsy. However if some amount of local anesthetic was absorbed into the blood stream, it can cause a bit of drowsiness and that is normal and will wear off.
Typically if just a local anesthetic such as Marcaine or Lidocaine was given you should not feel drowsy. If some reason sedation was given in addition to the local anesthetic that could account for drowsiness.
Often times, patients receiving local anesthetics may get additional medications which might be responsible for drowsiness. Local anesthetic injected into any tissue will find its way into the bloodstream and circulate in the body. At certain concentrations it can cause lightheaded ness, drowsiness, or even a seizure. Physicians and dentists know this and keep the total amount of local anesthetic within safe levels when injecting.
If you have severe pain for a long time, and a doctor gives you local anesthesia that completely eliminates your pain, then you may feel sleepy because you haven't slept well for days; otherwise, local anesthetics have no effect on alertness.
If only local anesthetic is used it will not make you drowsy unless large volumes are used. In most cases the volume of anesthetic used is usually small
