What number of Ambien (zolpidem) should I take?

Ambien (zolpidem) -- how many? Ambien (zolpidem) (or zolpodem) comes in 5mg and 10mg tablet strengths. Ambien (zolpidem) cr (controlled release) is available in 6.25mg and 12.5 mg tablet strengths. Most commonly, Pts are rx'ed one tab of whichever strength their doc thinks best, right before bedtime. However, it's most important that you follow the instructions your doc gave about how, exactly, to take your ambien (zolpidem). If unsure, give a call :)
