About Nitrazepam
Nitrazepam is a sedative used to treat insomnia. Nitrazepam is
in the group of drugs known as benzodiazepines, a class of antidepressants,
anti-panic agents, and muscle relaxants. Nitrazepam is usually used
as a short term treatment for temporary insomnia, but if used daily,
it will become ineffective in a few weeks. This medication has some
anticonvulsant properties, but US prescribing guidelines are unavailable
for this use.
Nitrazepam is only available by prescription in Canada, do
not use with narcotic pain medications, alcohol, or other
sedatives.
Nitrazepam Side Effects
Nitrazepam side effects are usually temporary, and fade with continued
treatment. Higher dosage also increases the risk of side effects.
Operating automobiles or heavy machinery is not recommended while
taking Nitrazepam, which should be taken before bedtime only when
you know you can have a full night's rest. Be aware of how this
medication affects you before attempting any potentially dangerous
activities.
Expected Nitrazepam side effect: Drowsiness.
Common Nitrazepam side effects: Fatigue or grogginess the
next morning, light-headedness, rebound insomnia (on stopping treatment),
slurred speech.
Less common Nitrazepam side effects: abdominal cramps, anxiety,
constipation, dry mouth, hyperventilation, blurred vision, nausea,
chest pain, change in sex drive, confusion, depression, headache,
change in appetite, insomnia, unusual dreams, change in salivation,
low blood pressure, racing heartbeat, fainting, nasal congestion,
sweating, weight change, skin irritation, twitching or tremors,

occur: hyperexcitement, muscle spasm, anxiety, hallucinations,
rage or other hostile behavior, tremors, insomnia, sleeping difficulties
or overstimulation.
Cautions: Nitrazepam has been known to interact undesirably with certain medical conditions. Tell your doctor if you have, or have a history of, any of the following conditions:
- Alcohol or drug abuse - may increase likelihood of Nitrazepam dependence
- Allergic reaction to Nitrazepam, or other benzodiazepine. Always
tell your doctor about any allergies before starting a medication.
- Borderline personality disorder or a history of violent behavior.
- Brain disease - may increase likelihood of side effects from
Nitrazepam
- Breathing difficulties such as asthma, bronchitis, emphysema,
or any other chronic lung disease - Nitrazepam may worsen this condition.
- Difficulty swallowing - This condition may become more pronounced
in children.
- Epilepsy or seizures - Abruptly starting or stopping treatment
with Nitrazepam may increase seizures. Although Nitrazepam can be used as
an aid to anti-tremor therapy, it should be used cautiously and
strictly according to a doctor's instructions in these cases.
- Glaucoma - Nitrazepam should not be prescribed to patients with acute
narrow-angle glaucoma. Patients receiving treatment for open angle
glaucoma should consult their doctor, as Nitrazepam may be an acceptable
treatment for them.
- Hyperactivity
- Kidney or liver problems - In isolated cases, Nitrazepam has been
reported to cause jaundice. If you experience yellowing of the
skin or eyes, seek medical treatment immediately. More Nitrazepam may
end up in your bloodstream if you have a pre-existing kidney or
liver condition, increasing the likelihood of side effects.
- Major Depression
- Myasthenia gravis - This autoimmune disorder characterized by
muscle weakness may be aggravated by Nitrazepam treatment.
- Porphyria - Nitrazepam (alprazolam) is listed as an unsafe drug for
porphyria, an enzyme deficiency that can cause fragile skin that
is sensitive to sunlight, digestive difficulties, anxiety, and
reddish-brown urine.
- Psychosis or other serious mental illness - Nitrazepam has not proved
to be an effective treatment for these conditions, and is not
recommended.
- Sleep apnea (temporary suspension of breathing during sleep)
- Nitrazepam may worsen this condition. Individuals with sleep apnea
should not generally use sedatives as sleep aids. (See Sleep Disorders)
Dependence: Nitrazepam has been known to be habit-forming. Withdrawal symptoms may occur if treatment is discontinued abruptly. Follow your doctor's advice about how much, and how often, you should take Nitrazepam. If you are considering stopping Nitrazepam treatment, ask your doctor how to safely decrease and then stop Nitrazepam.
Nitrazepam Interactions
Nitrazepam slows the central nervous system, and should be taken with
care with medications that do the same thing. When Nitrazepam is taken
with certain other medications, the rate of side effects may increase,
and the action of either medication may be increased or altered.
Certain medications can cause an undesirable build-up of Nitrazepam in
the body. Ask your doctor's advice about combining Nitrazepam with any
of the following:
- Alcohol - Nitrazepam should not be mixed with alcohol, it increases
the risk of overdose and fatal toxicity.

(meperidine), Codeine, Percocet
(oxycodone, acetaminophen), Vicodin
(hydrocodone, acetaminophen), Vicoprofen
(hydrocodone and ibuprofen) or OxyContin
(oxycodone) may accelerate central nervous system or respiratory
depression when taken with Nitrazepam. Also, Nitrazepam may decrease
the effectiveness of these medications as pain relievers.
- Norflex (orphenadrine)
- Risk of oversedation.
- Neoral, Sandimmune (cyclosporine)
- Nicotine - Heavy smoking may reduce the effectiveness of your
treatment.

Pertofrane or Norpramin (desipramine), Sinequan
(doxepin), Tofranil (imipramine), Aventyl or Pamelor (nortriptyline),
Vivactil (protriptyline), and Surmontil (trimipramine), may increase
the risk of side effects from Nitrazepam.

Talk with your doctor if you are considering mixing a sedative
medication like Nitrazepam with any other antidepressant, or any
medication that may cause drowsiness. Some medications can have
increased, unexpected, or severe side effects when mixed with others
that affect the central nervous system. Stimulants of any type may
blunt the effectiveness of Nitrazepam.
Nitrazepam Dosages
Nitrazepam comes in tablets, and may be prescribed in dosages of
5-10 mg at bedtime. Follow the directions on your prescription exactly.
Nitrazepam Directions
Nitrazepam should be taken exactly as your doctor recommends. Don't
take more or less than prescribed, and don't double your doses if
you should miss one. Take your doctor's advice about how quickly
or slowly to ease off Nitrazepam treatment if you plan to stop taking
it. Nitrazepam should not be started or stopped abruptly,
as it strongly increases the likelihood of side effects.
Inform your doctor, dentist, or anesthesiologist that you are taking
Nitrazepam before any kind of surgery or medical test. This medication
may interfere with certain test results. Nitrazepam should not be
combined with certain medications given during surgery.
Store Nitrazepam away from direct light and heat. Store in a dry
location; avoid storing it in the bathroom, near sinks, or other
areas where it may become damp. Do not use after the expiration
date.
Keep Nitrazepam away from children; both when storing it, and when
discarding any unused medication.
Nitrazepam may cause drowsiness or disorientation. Be cautious
if you plan to drive or operate heavy machinery, avoid these activities
if you find yourself feeling tired or experience slowed reactions.
Nitrazepam and Pregnancy
Nitrazepam is not recommended for women who are breastfeeding, pregnant,
or planning to become pregnant. Nitrazepam could cause breathing problems
or muscle weakness in an infant. Also, a newborn whose mother had
been taking Nitrazepam might experience withdrawal symptoms.
Other benzodiazepines, similar to Nitrazepam, have been seen to cause
an increase in birth defects. While Nitrazepam has not been demonstrated
to be a high risk factor for birth defects, the possibility exists
that it could increase their likelihood.
Nitrazepam and Children
Nitrazepam has been used to treat seizures in children, but there
are no US prescription guidelines.
Nitrazepam and Seniors
Older adults taking Nitrazepam are usually encouraged to start
with smaller doses of no more than 2.5 mg at bedtime, and limit
intake to the smallest effective dose. Seniors are more likely to
become too heavily sedated, or experience decreased muscle coordination.
