Clonazepam 2mg Tablets are prescription-only benzodiazepine tablets supplied on this page in a 100-tablet pack. Each tablet contains 2mg of clonazepam.
Clonazepam acts on gamma-aminobutyric acid (GABA), a chemical messenger that reduces excessive activity in the brain and nervous system. NHS information describes clonazepam as being used for conditions including epileptic seizures or fits, involuntary muscle spasms, panic disorder and, in some cases, restless legs syndrome.
Because this product may be supplied from different manufacturers, the licensed indication can vary by brand. For example, the current UK Neuraxpharm 2mg product information lists epilepsy and seizure disorders as its licensed indication. Always follow the prescription and patient leaflet belonging to the actual brand supplied.
Current selectable options include Neuraxpharm, Novumgen and Any Brand/No Preference, subject to availability.
For more information about the medicine class, read our guide to benzodiazepines and their different types.

This page is for generic Clonazepam 2mg Tablets, rather than a specific branded product such as Rivotril.
Current product details are:
Current UK medicine records confirm that licensed Clonazepam 2mg tablets are available in 100-tablet presentations.
Clonazepam is a benzodiazepine medicine.
It increases the effects of GABA in the brain. Depending on the condition being treated, this action can help reduce seizure activity, relax involuntary muscle activity and produce a calming effect.
If you want a broader explanation of how benzodiazepines work, see What Are Benzodiazepines & What Types Are There?.
People frequently search for clonazepam uses, but it is important to distinguish general clinical use from the licensed indication of a particular manufacturer.
NHS information describes clonazepam as being used for:
However, some current UK Clonazepam 2mg tablet SmPCs, including Neuraxpharm, specifically list epilepsy and seizure disorders as the licensed therapeutic indication.
This matters on a multi-brand product page: follow the reason your healthcare professional has prescribed clonazepam and the leaflet supplied with your specific brand, rather than assuming every manufacturer has identical licensed indications.
For related information concerning anxiety treatments, browse the Anti-Anxiety category.
How quickly clonazepam works depends on why it is being taken.
For seizures and involuntary muscle spasms, NHS guidance says it may take several days to around one week to work fully because the dose is usually increased gradually.
For panic disorder and restless legs syndrome, effects may begin within around one hour.
Do not take additional Clonazepam 2mg tablets simply because you do not notice an immediate effect.
Clonazepam can make people feel sleepy or drowsy, but sleepiness is an effect of the medicine rather than a reason to treat it as a routine sleeping tablet.
Persistent insomnia has many possible causes and may require a different treatment approach.
For broader information about sleep problems, read our guide to insomnia, its causes and ways to sleep better.
The phrase clonazepam dosage should not be confused with the strength printed on the product.
2mg means each tablet contains 2mg of clonazepam. It does not mean that 2mg is the correct dose for every person.
The appropriate dose depends on factors including:
NHS guidance states that for conditions such as epilepsy or muscle spasms, treatment generally starts at a lower dose and is increased gradually until the appropriate dose is reached.
For a more detailed explanation, read our Clonazepam tablets dosage and safety guide.
Take clonazepam exactly as instructed by your doctor or pharmacist.
Tablets should be swallowed with water and may be taken with or without food.
Do not:
This page supplies tablets, so instructions relating to clonazepam liquid are not relevant to this product and should not be included in the product copy.
If you forget a clonazepam dose, take it when you remember unless it is nearly time for your next dose.
If the next dose is due soon, skip the forgotten dose and continue with your normal schedule.
Never take two doses at the same time and never take an additional dose to compensate for a missed one.
Treatment duration depends on the reason clonazepam has been prescribed.
For epilepsy, it can sometimes be prescribed long term. For other conditions, the continued need for treatment should be reviewed by the prescribing healthcare professional.
This means the simple statement that clonazepam should always be stopped after two or four weeks would be inaccurate for every patient.
Do not suddenly stop clonazepam without medical advice.
With regular use, the body can become physically dependent on a benzodiazepine. Abrupt withdrawal can cause symptoms and, importantly, may provoke seizures in susceptible people.
Where treatment is being stopped, the dose may need to be reduced gradually.
Clonazepam side effects vary between individuals, and not everyone experiences them.
Common side effects reported by the NHS include:
Speak to a doctor or pharmacist if a side effect is persistent, worsening or interfering with normal activities.
Clonazepam can affect:
Do not drive, cycle or operate machinery if you feel sleepy, confused, dizzy or unsteady.
Seek urgent medical advice if symptoms develop such as:
Memory problems or amnesia should also be discussed with a doctor.
Call 999 or go to A&E immediately if clonazepam causes serious difficulty breathing or a significant change in breathing.
Clonazepam addiction, physical dependence, tolerance and withdrawal are related but different issues.
Tolerance means the medicine may appear to have less effect after repeated use.
Physical dependence means the body has adapted to the medicine and withdrawal symptoms can occur if it is stopped too quickly.
Addiction can involve difficulty controlling medicine use or continuing to take it despite harm.
In January 2026, the MHRA strengthened benzodiazepine warnings specifically around addiction, dependence, withdrawal and tolerance.
Do not increase your clonazepam dose yourself if it feels less effective.
Stopping regular clonazepam abruptly can cause clonazepam withdrawal symptoms.
NHS information describes possible symptoms including:
Current Neuraxpharm product information also warns that abrupt withdrawal can cause anxiety, sleep disturbance, restlessness, tremor, sweating, headache, muscle pain and, in severe cases, seizures or hallucinations.
Dose reduction should therefore be planned with the prescribing healthcare professional.
Do not drink alcohol while taking clonazepam.
Alcohol can significantly increase clonazepam’s sedative effects and can lead to dangerously deep sleep, difficulty waking and impaired breathing.
Particular caution is required when benzodiazepines such as clonazepam are combined with opioid medicines.
Current product information warns that the combination can increase the risk of:
Tell your doctor or pharmacist about all medicines you take, including prescription medicines, non-prescription medicines and supplements.
Current UK product information identifies important precautions and contraindications involving conditions such as:
Pregnancy and breastfeeding also require individual medical advice.
Because this product can be supplied under different manufacturers, the patient information leaflet may differ according to the brand received.
One of the selectable manufacturers on this page is Neuraxpharm, whose current UK patient leaflet for Clonazepam Neuraxpharm 2mg was updated in May 2026.
Always read the leaflet supplied inside your actual pack before taking the medicine.
The leaflet should be checked for:
Do not assume that the Neuraxpharm leaflet applies to Novumgen or another manufacturer.
If the dispensing label or manufacturer leaflet differs from general information on this page, follow your prescribed instructions and ask your doctor or pharmacist if anything is unclear.
