Zopim Side Effects

There is evidence of a dose-relationship for adverse effects associated with zolpidem tartrate use, particularly for certain CNS and gastrointestinal events. As recommended in Dosage & Administration, they should, in theory, be less if zolpidem tartrate is taken immediately before retiring, or in bed. They occur most frequently in elderly patients.
Daytime drowsiness, reduced alertness, confusion, fatigue, headache, dizziness, muscle weakness, gait disturbances or diplopia. These phenomena usually occur predominantly at the start of therapy.
Other effects like gastrointestinal disturbances, changes in libido or skin reactions have been reported occasionally.
Amnesia: anterograde amnesia may occur using therapeutic dosages, the risk increasing at higher dosages. Amnestic effects may be associated with inappropriate behaviour.
Psychiatric and paradoxical reactions: reactions like restlessness, agitation, irritability, aggressiveness, delusion, rage, nightmares, hallucinations, psychoses, inappropriate behaviour, somnambulism and other adverse behavioural effects are known to occur when using zolpidem tartrate. Such reactions are more likely to occur in the elderly.
Depression: pre-existing depression may be unmasked during use of zolpidem tartrate. Since insomnia may be a symptom of depression, the patient should be re-evaluated if insomnia persists.
