Can Zolpidem 5mg be cut in half?

It can be done with a very sharp cutting instrument. =)

...but yes, it will still be effective as a sleeping aide if you're using half. Since this is a very strong medicine and can be addictive, I cut it in half for my wife and also give her one pill of Melatonin 10MG as a side supplement. There is no drug in Melatonin...it's a substance that's found naturally in your body near and at the time when you fall asleep. It's working really well for her insomnia. The Melatonin helps her fall into a deep sleep, and Zolpidem helps keep her sleeping like that. She wakes up refresh without feeling any side effects from Zolpidem.
