temazepam

Temazepam (commonly known by brand names such as Restoril) is an intermediate-acting benzodiazepine hypnotic primarily prescribed for the short-term treatment of severe insomnia. In the UK, it is classified as a Class C controlled substance (Schedule 3) due to its potential for dependence and misuse.

Key Clinical Indications

Healthcare professionals prescribe temazepam for short-term management of specific clinical needs:

• Severe Insomnia: Short-term relief (typically 2 to 4 weeks maximum) for severe, disabling sleep disturbances, particularly when difficulty falling asleep or waking up frequently throughout the night causes distress.

• Pre-medication / Pre-procedure Sedation: Given prior to surgical, medical, or dental procedures to reduce acute anxiety and promote relaxation.

How Temazepam Works

Temazepam acts on the central nervous system by enhancing the activity of Gamma-Aminobutyric Acid (GABA), the brain’s primary inhibitory neurotransmitter:

• Sedative-Hypnotic Effect: Binding to GABA-A receptors increases neural inhibition, resulting in reduced brain activity, muscle relaxation, and rapid onset of sleep.

• Sleep Architecture: It helps shorten the time required to fall asleep (sleep onset latency) and reduces night-time awakenings.

Dosing & Administration Guidelines

• Timing: Taken orally (as tablets or oral solution) roughly 30 minutes before going to bed.

• Duration: Strictly intended for short-term use (usually 7 to 14 days, up to a maximum of 4 weeks). Prolonged use rapidly reduces efficacy as tolerance develops.

• Uninterrupted Sleep: Ensure you can dedicate 7 to 8 hours to uninterrupted sleep after taking a dose to minimize morning hangover effects.

Common Side Effects & Management

Important Precautions & Drug Interactions

• Drug Interactions:

  • Antifungals (e.g., Itraconazole): Inhibitors of CYP enzyme pathways can impair temazepam clearance, leading to elevated blood levels and prolonged, excessive sedation.

  • Alcohol & Central Nervous System Depressants: Concurrent use of alcohol, opioids, or other sedatives creates a high risk of profound sedation, severe respiratory depression, coma, and overdose.

• Pregnancy & Breastfeeding: Benzodiazepines cross the placenta and pass into breast milk. Use during pregnancy or lactation should generally be avoided due to risks of neonatal flaccidity (“floppy infant syndrome”) and respiratory distress.

Safety Warnings & UK Regulations

• Dependence & Withdrawal: Using temazepam regularly for more than a few weeks leads to tolerance and physical dependence. Abrupt cessation can trigger severe withdrawal symptoms (rebound insomnia, tremors, sweating, anxiety, and seizures). Doses must always be tapered gradually under medical supervision.

• Street Names & Counterfeits: Terms such as “jellies” or “eggs” historically referred to gel-filled capsule formulations that were removed from UK practice due to severe illicit abuse risks. Purchasing “temazepam” from illegal online sellers or street markets carries severe health risks, as unregulated products often contain hazardous, adulterated, or incorrectly dosed compounds.

• Prescription Status: Strictly available on prescription from a GMC-registered doctor or qualified prescriber, and dispensed through a licensed UK pharmacy.
