Ambien Overdose Symptoms


Excessive sleepiness can indicate an overdose of Ambien. Other signs of an overdose include

finding it difficult to breathe and tiny pupils. Severe Ambien overdoses can lead to a coma and

even death. Common examples of death involve combining Ambien with alcohol, opiate drugs

or other medications, which limit the function of the central nervous system. When treated with

the benzodiazepine drug, flumazenil, the effects from an overdose of Ambien can be undone.


Ambien Side Effects


In a controlled laboratory trial in the U.S. involving 1701 patients who received anywhere from

1.25 to 90 milligrams of zolpidem (Ambien), approximately four percent had to discontinue

treatment after suffering from adverse side effects. The most common side effects in this trial

were nausea at 0.6 percent, vomiting at 0.5 percent, sleepiness during the day at 0.5 percent, a

headache at 0.5 percent, and feeling dizzy at 0.4 percent.


Trials performed overseas involving 1,959 patients who took doses ranging from one to 50

milligrams of zolpidem gave the same overall result, where about four percent stopped taking

the medication after noticing side effects. In these trials, the following side effects were noted:

a drowsy feeling during the day, 1.1 percent; a feeling of vertigo, or dizziness, 0.8 percent; an

upset stomach, 0.5 percent; a loss of memory, 0.5 percent; falls while sleepwalking, 0.4 percent;

and a headache, 0.4 percent.


Trials using Ambien on a short-term basis of no more than 10 nights with the patients taking

dosages up to 10 milligrams per night showed higher instances of side effects in the following

areas: diarrhea, one percent; dizzy spells, one percent; a sleepy feeling during the day, two

percent. Trials in which patients were administered Ambien for a month with doses up to 10

milligrams boosted side effects even more, with the following results, a sluggish, drugged feeling

during the day, three percent; a dizzy feeling, five percent.
