Antipsychotics: Medicines used to treat paranoia and confusion are called neuroleptics or antipsychotics. Examples of these medicines are haloperidol, risperdone (Risperdal), and olanzepine (Zyprexa). Side effects can include drowsiness, rigidity, and unusual movements.

Antidepressants: Drugs such as fluoxetine (Prozac), paroxetine (Paxil), sertraline (Zoloft), and nortriptyline (Pamelor) are used to treat depression. Side effects of these medicines can include drowsiness, dry mouth, and constipation.

Antianxiety medications: These medications--which include alprazolam (Xanax), lorazepam (Ativan), and buspirone (BuSpar)--often produce drowsiness.
