Galenika Rivotril 2mg contains clonazepam, a prescription benzodiazepine medicine. The product shown on this page contains 2mg of clonazepam per tablet and is supplied as a pack of 30 tablets.
Clonazepam is used for conditions including epileptic seizures or fits, involuntary muscle spasms and panic disorder, and it may sometimes be used for restless legs syndrome. It works by increasing the activity of gamma-aminobutyric acid (GABA), a chemical messenger that reduces excessive activity in the brain and nervous system.
Because Rivotril 2mg belongs to the benzodiazepine group, it can cause drowsiness and can also lead to tolerance, physical dependence, addiction and withdrawal. UK warnings for benzodiazepines were strengthened in 2026 to make these risks clearer.
For a broader explanation of this medicine group, read our guide to benzodiazepines and their different types.
Always take clonazepam according to your prescription and dispensing label. The 2mg strength is the amount of clonazepam in each tablet; it is not a universal dose recommendation.

The product on this page is:
Clonazepam is specifically listed by the UK government as a Class C, Schedule 4 Part 1 controlled drug.
Rivotril is the brand name shown on this Galenika product, while clonazepam is the active medicine contained in the tablet.
This distinction is useful because people may search for:
Rivotril
Rivotril 2mg
Galenika Rivotril
Clonazepam 2mg
Rivotril clonazepam
but they are not all separate active medicines.
This page should primarily describe the Galenika Rivotril 2mg product, while your separate generic Clonazepam product page can remain focused on generic Clonazepam 2mg tablets. That separation reduces unnecessary cannibalisation.
Current NHS information describes clonazepam uses including:
The reason clonazepam has been prescribed for an individual depends on their diagnosis and clinical circumstances.
For broader site information relating to medicines used for anxiety-related conditions, visit our Anti-Anxiety range.
Clonazepam belongs to the benzodiazepine group.
It increases the effects of GABA, a naturally occurring inhibitory chemical messenger in the brain. Depending on the condition being treated, this can reduce seizure activity, relax muscle activity and contribute to a calming effect.
How quickly clonazepam works varies according to why it is being taken. NHS guidance notes that it may take several days to a week to work fully for seizures and involuntary muscle spasms because the dose is usually increased gradually. For panic disorder and restless legs syndrome, effects may begin within around an hour.
Do not take extra Rivotril 2mg tablets simply because an effect is not immediate.
Clonazepam can cause sleepiness, but this does not mean Rivotril should be treated as a routine general sleeping tablet.
If persistent sleep difficulty is the main concern, it is useful to understand possible causes rather than relying only on sedating medicines. Read our guide to insomnia, its causes and ways to sleep better.
The site also has a wider Sleeping Aids section, but any prescription treatment should follow the person’s own medical advice.
A common search is clonazepam dosage, but the 2mg strength shown on this page should not be used to choose your own dose.
Clonazepam tablets are available in several strengths, and the amount prescribed depends on the condition being treated, age, response to treatment and other health factors. NHS guidance states that treatment for epilepsy or muscle spasms often starts at a lower dose and is increased gradually.
Your doctor will also decide whether the prescribed amount should be taken as one dose or divided through the day.
Always follow:
Do not:
Take clonazepam tablets with a drink of water.
NHS guidance states that clonazepam tablets may be taken with or without food.
This product page relates specifically to Rivotril 2mg tablets, so instructions for clonazepam liquid are not relevant to this SKU and should not remain in the page copy.
If you forget a dose, take it when you remember unless it is nearly time for your next scheduled dose.
In that situation, leave out the forgotten dose and continue normally.
Never take two doses at the same time and never take an extra dose to compensate for a missed one.
Treatment duration depends heavily on why clonazepam has been prescribed.
For epilepsy, NHS guidance notes that clonazepam may be prescribed long term. For other conditions, the need for ongoing treatment should be reviewed regularly.
This is an important distinction from some other benzodiazepines used primarily for short-term anxiety or insomnia treatment.
Do not suddenly stop regular clonazepam treatment without discussing it with your doctor.
Withdrawal symptoms can occur if benzodiazepines are stopped abruptly or reduced too quickly, and gradual dose reduction may be required.
This is especially important for people taking clonazepam for epilepsy because abrupt cessation can increase the risk of seizures.
Your keyword data shows clonazepam side effects is one of the strongest supporting search topics for this product, and it is clinically important information to include.
Common side effects can include:
Do not drive, cycle or operate machinery if clonazepam makes you sleepy, dizzy, confused or unsteady.
Speak to your doctor or pharmacist if side effects continue, become troublesome or worsen.
Seek urgent medical advice if you experience symptoms including:
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 significant changes in breathing.
Clonazepam addiction, dependence and withdrawal are separate but related risks.
Tolerance means the medicine may seem to work less effectively after repeated use.
Physical dependence means the body has adapted to the medicine and withdrawal symptoms may occur if treatment is stopped or reduced too quickly.
Addiction may involve a strong desire to continue taking the medicine or difficulty controlling its use.
The MHRA strengthened warnings for benzodiazepines in January 2026 because these medicines are known to carry risks of addiction, dependence, withdrawal and tolerance. The MHRA also notes that dependence can occur even during therapeutic use.
Possible warning signs can include:
If Rivotril appears less effective, do not increase your dose yourself. Speak to your prescriber.
For general information on how this medicine group works and why these risks occur, see our benzodiazepine information guide.
Possible clonazepam withdrawal symptoms after sudden discontinuation can include:
Withdrawal risk is one reason clonazepam should not be stopped without medical advice.
The appropriate reduction schedule differs between individuals and may take time, particularly after prolonged treatment.
Do not drink alcohol while taking clonazepam.
Alcohol can substantially increase clonazepam’s sedative effects and can lead to very deep sleep, difficulty waking and dangerous breathing problems.
Tell your doctor or pharmacist about all medicines you use.
Medicines that may increase side-effect risk or interact with clonazepam include:
Combining several medicines that suppress the central nervous system can increase drowsiness and breathing-related risks.
Tell your doctor before taking clonazepam if you have conditions such as:
Medical advice is also important during pregnancy or breastfeeding.
Taking more Rivotril 2mg than prescribed can be dangerous.
Possible effects of too much clonazepam can include:
Contact NHS 111 if you take more than your prescribed dose of clonazepam.
If you need to attend A&E, do not drive yourself. Take the medicine packaging, remaining tablets and details of any other medicines taken.
Call 999 immediately if someone develops severe breathing problems, becomes unconscious, cannot be woken, or has another life-threatening reaction.
A Galenika-specific patient leaflet has not been supplied for this website content, so this page should not invent manufacturer-specific ingredients, excipients or detailed Galenika dosing instructions.
Always read the leaflet contained in the actual Rivotril pack supplied to you.
The leaflet should be checked for information about:
Current UK clonazepam 2mg patient leaflets confirm that clonazepam is a benzodiazepine tablet medicine and contain detailed safety information specific to the licensed product concerned.
Because different manufacturers can use different inactive ingredients and tablet designs, do not assume a UK generic clonazepam leaflet is identical to the Galenika Rivotril leaflet.
