Is Lorazepam a Controlled Drug in the UK?

Yes, lorazepam is a controlled drug in the UK.

Lorazepam is a benzodiazepine that is sometimes used to treat anxiety and related sleep problems, as well as being used as a pre-med before operations and other medical procedures.

Restrictions exist because benzodiazepines, including lorazepam, can be misused and can also cause dependence and addiction.

What Is Lorazepam?

Lorazepam is one of a class of drugs called benzodiazepines (‘benzos’), which act as sedatives by slowing down the central nervous system. According to the NHS, lorazepam is believed to work by increasing the levels of a calming chemical in the brain called gamma-aminobutyric acid (GABA).

It can be used on prescription only in the UK for issues such as anxiety, panic attacks, severe agitation, short-term insomnia treatment and before some medical procedures.

Its common brand name is Atvian.

Is Lorazepam a Controlled Drug in the UK?

Lorezepam is strictly controlled in the UK. It is classified as a Class C controlled drug. This means that unlawful possession can lead to up to 2 years in prison, an unlimited fine, or both. Supplying, dealing, or manufacturing Class C drugs can result in up to 14 years in prison, an unlimited fine, or both

Lorazepam falls under Schedule 4 Part I of the Misuse of Drugs Regulations.

Prescriptions and supply of the drug are regulated due to the risk of misuse and dependency.

What Does Schedule 4 Mean?

Controlled drugs are divided into a number of different schedules. Schedule 4 drugs have recognised medical uses but still carry misuse risks. Lorazepam belongs Schedule 4, which is the same group as many other benzodiazepines.

Why Is Lorazepam Controlled?

Using lorazepam for more than a short, controlled period of time can result in a growing tolerance to the drug, meaning more and more is needed for the same effect. It can also produce a psychological and physical dependence, which can lead to a range of withdrawal symptoms.

Lorazepam is sometimes misused – either by using beyond prescribed doses and instructions, using without a prescription or using it recreationally. As well as addiction, there is a risk of overdose if misused. This can cause low blood pressure, ataxia (neurological disorders that affect co-ordination, balance and speech), confusion, coma, extreme drowsiness, muscle weakness and even death. The risks can increase when combined with other depressants such as opioids or alcohol.

How Is Lorazepam Prescribed?

Lorazepam should only be prescribed by relevant healthcare professionals. It is usually prescribed short term, starting at the lowest effective dose, with regular reviews by the prescriber or other healthcare professionals and with monitoring for signs of dependency.

Can You Become Addicted to Lorazepam?

It’s worth remembering that not everyone will develop a lorazepam addiction and it is generally safe when used as directed.

• Anxiety
• Insomnia
• Irritability
• Tremors
• Sweating
• Panic symptoms

Severe withdrawal can occur in some cases and should be medically supervised.

Is It Illegal to Possess Lorazepam Without a Prescription?

The fact that lorazepam is a Class C controlled substance means that, yes, it may be illegal to possess this drug without a proper prescription.

It’s also worth remembering that it is also unlawful to share prescription medications with someone else.

Charges of providing and supplying are generally treated more harshly than possession and can be very serious.

How Is Lorazepam Addiction Treated?

Lorazepam addiction may be treated in a number of different ways. Supply of the drug may be tapered or reduced gradually, in order to help the person ‘wean off’ lorazepam. In any case, drug detox and withdrawal should be carefully monitored and managed. Other treatments can include a range of therapies to address the psychological aspects of addiction, along with relapse prevention sessions and aftercare to provide ongoing support.

In some cases, a holistic residential drug rehab programme may be the most comprehensive and effective way to treat addiction.

When Should You Seek Help?

In general you should seek help if you notice any of the potential signs of addiction listed above, if you experience difficulty reducing use or failed attempts to stop, or notice that your use of lorazepam is having an impact on your daily life.
