Important: How To Use This Information
This is a summary and does NOT have all possible information about this product. This information does not assure that this product is safe, effective, or appropriate for you. This information is not individual medical advice and does not substitute for the advice of your health care professional. Always ask your health care professional for complete information about this product and your specific health needs.
Taking nitrazepam with opioid medications (such as codeine, hydrocodone) may increase your risk of very serious side effects, including death. To lower your risk, your doctor should have you take the smallest dose of nitrazepam that works, and take it for the shortest possible time. Get medical help right away if any of these very serious side effects occur: slow/shallow breathing, unusual lightheadedness, severe drowsiness/dizziness, difficulty waking up.
This medication is used in adults for the short-term treatment of trouble sleeping (insomnia). It may help you fall asleep faster and decrease the number of times you awaken during the night. It may also help you sleep for a longer time. Nitrazepam is also used in children and infants to treat a certain type of seizure (myoclonic).
This medication belongs to a class of drugs called benzodiazepines, which act on the brain to produce a calming effect. It works by enhancing the effects of a certain natural chemical in the body (GABA).
How To Use
To treat insomnia, take this medication by mouth with or without food as directed by your doctor, usually before bedtime. This medication can be chewed or dissolved in liquid if you are unable to swallow it whole.
Do not use this medication if you have less than 7 to 8 hours to sleep. Doing so increases the risk of daytime drowsiness and temporary memory loss.
To treat seizures in infants and children, give the medication by mouth as directed by your doctor, usually 3 times a day.
Dosage is based on your medical condition and response to treatment. Nitrazepam is not usually used for more than 7 to 10 days when treating insomnia. Long-term use can cause the medication to build up in your body, increase side effects, and cause dependence. It can make your insomnia worse after you stop taking the medication (rebound insomnia).
If you suddenly stop using this medication, you may have withdrawal symptoms (such as depressed/anxious mood, stomach/muscle cramps, vomiting, sweating, shakiness, seizures). To help prevent withdrawal, your doctor may lower your dose slowly. Withdrawal is more likely if you have used nitrazepam for a long time or in high doses. Tell your doctor or pharmacist right away if you have withdrawal.
Though it helps many people, this medication may sometimes cause addiction. This risk may be higher if you have a substance use disorder (such as overuse of or addiction to drugs/alcohol). Do not increase your dose, take it more often, or use it for a longer time than prescribed. Properly stop the medication when so directed.
When used for an extended period, this medication may not work as well and may require different dosing. Talk with your doctor if this medication stops working well.
Tell your doctor if you continue to have trouble sleeping or your child's seizures persist or worsen.
