What is Restoril?
Restoril is used to treat insomnia (trouble falling or staying asleep).
Restoril works by slowing down the central nervous system (brain), causing drowsiness which helps patients fall asleep.
Restoril can slow or stop your breathing, especially if you have recently used an opioid medication, alcohol, or other drugs that can slow your breathing.
Never take Restoril if you do not have at least 7 to 8 hours to sleep before being active again.
Do not use Restoril if you are pregnant. Temazepam can cause birth defects or life-threatening withdrawal symptoms in a newborn. Use effective birth control to prevent pregnancy while taking this medicine.
Some people using this medicine have engaged in activity such as driving, eating, or making phone calls and later having no memory of the activity. If this happens to you, stop taking Restoril and talk with your doctor about another treatment for your sleep disorder.
Temazepam may be habit-forming and should be used only by the person it was prescribed for. This medicine should never be shared with another person, especially someone who has a history of drug abuse or addiction. MISUSE OF TEMAZEPAM CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medication in a place where others cannot get to it.
Temazepam may cause a severe allergic reaction. Stop taking this medicine and get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat. Take this medication only when you are getting ready for several hours of sleep. You may fall asleep very quickly after taking the medicine.
Before taking this medicine
Do not use Restoril if you are pregnant. It could harm the unborn baby.
If you use temazepam while you are pregnant, your baby could become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks.

lung disease or breathing problems;
