Nitrazepam Tablets 5mg: Uses & Safety
Nitrazepam tablets are prescription medicines used for the short-term treatment of severe insomnia. They belong to a group of medicines called benzodiazepines.
Nitrazepam affects the central nervous system and produces sedative effects. As a result, it may help certain patients who experience serious sleeping difficulties.
However, nitrazepam is not suitable for everyone. It can cause daytime drowsiness, dependence, and withdrawal symptoms.
In the UK, nitrazepam is a prescription-only medicine. Treatment requires professional assessment and appropriate prescribing.

What Are Nitrazepam Tablets?
Nitrazepam is a long-acting benzodiazepine with hypnotic properties.
Doctors may prescribe it when insomnia is severe, disabling, or causing significant distress.
However, the medicine does not cure the underlying cause of insomnia.
For this reason, healthcare professionals should assess possible causes before considering treatment.
These may include stress, medical conditions, medication effects, or other sleep disorders.

What Are Nitrazepam Tablets Used For?
Nitrazepam is used for the short-term treatment of severe insomnia.
Insomnia can involve several symptoms. For example, some people struggle to fall asleep. Others wake repeatedly during the night.
In addition, poor sleep may affect concentration, mood, and daily functioning.
Nitrazepam may help certain patients manage these symptoms.
Nevertheless, doctors should consider whether medication is necessary.
For persistent insomnia, cognitive behavioural therapy for insomnia (CBT-I) is an important evidence-based treatment.
How Do Nitrazepam Tablets Work?
Nitrazepam enhances the effects of gamma-aminobutyric acid, commonly called GABA.
GABA is an inhibitory neurotransmitter. It helps reduce activity in the central nervous system.
Nitrazepam increases GABA-related inhibitory effects. Consequently, it produces sedation and can promote sleep.
However, the same mechanism can impair alertness, coordination, and memory.
These effects may continue into the following day because nitrazepam is long-acting.
Nitrazepam 5mg Dosage Information
Nitrazepam 5mg is a licensed UK tablet strength.
The product information for Mogadon 5mg describes 5mg at bedtime as the usual adult dose.
However, the appropriate dose depends on the patient’s age, health, response, and other medicines.
Older adults and patients with certain medical conditions may require lower doses.
Important precautions include:
- Follow the prescriber’s instructions.
- Do not increase the prescribed dose.
- Do not take extra tablets during the night.
- Avoid alcohol during treatment.
- Allow sufficient time for uninterrupted sleep.
- Follow the prescribed withdrawal plan.
Treatment should be as short as possible.
Do not use general dosage information as a substitute for an individual prescription.
How Long Can Nitrazepam Be Taken?
Nitrazepam is generally intended for short-term use.
UK product information recommends limiting treatment to the shortest possible duration.
For insomnia, treatment should generally not exceed four weeks, including any dose-reduction period.
However, the prescriber must assess individual circumstances.
Longer treatment increases concerns about tolerance, dependence, and withdrawal.
Therefore, patients should discuss the expected treatment duration before starting the medicine.
Possible Side Effects of Nitrazepam
Like other benzodiazepines, nitrazepam can cause adverse effects.
Commonly reported side effects
These include:
- Daytime drowsiness

Older adults may be particularly sensitive to these effects.

Nitrazepam Warnings and Precautions
Nitrazepam requires particular caution in people with certain medical conditions.
These include:
- Respiratory disorders
- Sleep apnoea
- Liver impairment
- Muscle weakness disorders
- A history of substance misuse
- Certain mental health conditions
In addition, nitrazepam may increase the risk of falls in older adults.
Patients should tell their prescriber about all medicines and supplements they take.
Nitrazepam and Alcohol
Alcohol can increase the sedative effects of nitrazepam.
As a result, combining the two substances may cause dangerous drowsiness and breathing problems.
Avoid alcohol during nitrazepam treatment.
Nitrazepam and Driving
Nitrazepam may impair concentration, coordination, and reaction time.
Furthermore, its effects may continue into the following day.
Do not drive or operate machinery if your ability is impaired. Follow your prescriber’s advice and the patient information leaflet.
Nitrazepam Dependence and Withdrawal
Nitrazepam can cause physical dependence.
Over time, some patients may develop tolerance. This means the medicine produces less of the expected effect.
However, increasing the dose without medical advice can create serious risks.
Stopping suddenly after repeated use may cause withdrawal symptoms.
These can include:
- Anxiety
- Rebound insomnia
- Restlessness
- Tremors
- Sweating
- Confusion
- Seizures in severe cases
Therefore, patients should follow an individual withdrawal plan prepared by their healthcare professional.
Nitrazepam vs Zopiclone

| Feature | Nitrazepam | Zopiclone |
|---|---|---|
| Medicine class | Benzodiazepine | Z-drug |
| Common UK tablet strength | 5mg | 3.75mg and 7.5mg |
| Duration of action | Long-acting | Shorter-acting |
| Main indication | Severe insomnia | Severe insomnia |
| Dependence risk | Yes | Yes |
| Prescription required | Yes | Yes |
Neither medicine is automatically the better option.
The appropriate treatment depends on the patient’s medical history, symptoms, and professional assessment.
