Has anyone experienced serious side effects from Lorazapam?

Answer 1

One of the major problems with lorazepam is addiction. Others may inclue an allergic reaction (difficulty breathing; closing of the throat; swelling of the lips, face, or tongue; or hives);
sores in the mouth or throat;
yellowing of the skin or eyes;
a rash;
hallucinations or severe confusion; or
changes in vision.
Other, less serious side effects may be more likely to occur. Continue to take lorazepam and talk to your doctor if you experience

drowsiness, dizziness, or clumsiness;
depression;
nausea, vomiting, diarrhea, or constipation;
difficulty urinating;
vivid dreams;
headache;
dry mouth;
decreased sex drive; or
changes in behavior.
