Clonazepam is a type of medicine that belongs to the class of benzodiazepines and anticonvulsants. It is used to treat various conditions that involve seizures, anxiety, panic attacks and movement disorders. It is also known by its brand names Klonopin and Rivotril.
But how much do you know about clonazepam? How does it work, how should you use it, what are the possible side effects and interactions, and who should avoid it? In this blog post, we will answer some of the most frequently asked questions about clonazepam and provide you with useful information to help you use this medication safely and effectively.
What is clonazepam and how does it work?
Clonazepam is a synthetic drug that was developed in the 1960s by a pharmaceutical company called Hoffmann-La Roche. It was first approved by the Food and Drug Administration (FDA) in 1975 for the treatment of certain seizure disorders, such as absence seizures or Lennox-Gastaut syndrome. Later, it was also approved for the treatment of panic disorder and akathisia (a movement disorder caused by certain antipsychotic drugs). It is available in various forms, such as tablets, orally disintegrating tablets, oral solution and injection. It can be bought with a prescription from a doctor.
Clonazepam works by enhancing the activity of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain. GABA is an inhibitory neurotransmitter that reduces the activity of nerve cells and helps regulate mood, sleep, anxiety and muscle tone. By increasing the effect of GABA, clonazepam reduces the abnormal electrical activity in the brain that causes seizures and anxiety. Clonazepam also has muscle relaxant and sedative effects.
How should you use clonazepam?
The dose and frequency of clonazepam depend on your age, weight, medical condition and response to treatment. You should always follow the instructions on the label or the prescription from your doctor. Do not take more than the recommended dose or for longer than advised.
The usual adult dose of clonazepam for seizure disorders is 0.5 mg to 1 mg three times a day, gradually increased to a maximum of 20 mg per day if needed. The usual adult dose of clonazepam for panic disorder is 0.25 mg twice a day, gradually increased to a maximum of 4 mg per day if needed. The usual adult dose of clonazepam for akathisia is 0.5 mg to 2 mg per day as needed.
The usual pediatric dose of clonazepam for seizure disorders is 0.01 mg to 0.03 mg per kg of body weight per day divided into two or three doses, gradually increased to a maximum of 0.2 mg per kg per day if needed. The usual pediatric dose of clonazepam for panic disorder is not established.
The usual OTC dose of clonazepam for anxiety or insomnia is not recommended.
You can take clonazepam with or without food, but taking it with food may help prevent stomach upset. Do not crush, chew or break the tablets; swallow them whole with a glass of water. If you are using the orally disintegrating tablets, place them on your tongue and let them dissolve. If you are using the oral solution, measure the dose with a special dropper or syringe and swallow it. If you are using the injection, follow the directions on the package or the prescription from your doctor.
If you miss a dose of clonazepam, take it as soon as you remember, unless it is almost time for your next dose. In that case, skip the missed dose and continue with your regular schedule. Do not double the dose to make up for the missed one.
If you take too much clonazepam, seek medical attention immediately. Symptoms of overdose may include drowsiness, confusion, slurred speech, loss of coordination, slow or shallow breathing, coma and death.
What are the possible side effects and interactions of clonazepam?
Clonazepam is generally well tolerated by most people, but it can cause some side effects in some cases. The most common side effects are:
- Drowsiness, fatigue or weakness
- Dizziness or lightheadedness
- Impaired coordination or balance
- Memory or concentration problems
- Blurred vision or dry eyes
- Dry mouth or increased saliva
- Nausea, vomiting, constipation or diarrhea
- Loss of appetite or weight changes
- Headache or pain
- Mood changes, such as depression, anxiety, irritability or aggression
Most of these side effects are mild and temporary and can be reduced by taking clonazepam with food or milk. However, some side effects can be serious and require medical attention. These include:
- Allergic reactions, such as rash, itching, hives, swelling, difficulty breathing or anaphylaxis (a severe and potentially life-threatening reaction that requires immediate medical attention)
- Severe skin reactions, such as Stevens-Johnson syndrome or toxic epidermal necrolysis (a rare but serious condition that causes blistering and peeling of the skin and mucous membranes)
- Nervous system problems, such as seizures, confusion, hallucinations, psychosis, suicidal thoughts or behavior, coma and death
- Respiratory problems, such as slow or shallow breathing, respiratory depression or arrest
- Liver problems, such as hepatitis (inflammation of the liver) or jaundice (yellowing of the skin and eyes)
- Blood problems, such as anemia (low red blood cell count), leukopenia (low white blood cell count), thrombocytopenia (low platelet count) or agranulocytosis (severe drop in white blood cells)
If you experience any of these side effects while taking clonazepam, stop taking it and contact your doctor right away.
Clonazepam can also interact with other drugs and affect their effectiveness or increase their side effects. Some of the drugs that can interact with clonazepam are:
- Alcohol and other central nervous system depressants (such as opioids, antihistamines, sedatives, hypnotics or muscle relaxants), which can increase the sedative and respiratory effects of clonazepam and cause severe drowsiness, confusion, loss of coordination, slow or shallow breathing, coma and death. You should avoid alcohol and other central nervous system depressants while taking clonazepam and for at least 3 days after you stop taking it.
- Anticonvulsants (seizure medications), such as phenytoin, phenobarbital, carbamazepine or valproic acid, which can decrease the levels and effects of clonazepam. You may need to monitor your blood levels of these drugs and adjust your dose of anticonvulsants while taking clonazepam.
- Antidepressants, such as fluoxetine, paroxetine, sertraline, citalopram, escitalopram or venlafaxine, which can increase the levels and effects of clonazepam. This can increase the risk of serotonin syndrome, a rare but serious condition that causes agitation, confusion, hallucinations, fever, sweating, tremors, muscle rigidity and seizures. You should consult your doctor before taking clonazepam with any antidepressant.
- Antifungals, such as ketoconazole, itraconazole or voriconazole, which can increase the levels and effects of clonazepam. You may need to monitor your blood levels of these drugs and adjust your dose of antifungals while taking clonazepam.
- Antibiotics, such as erythromycin, clarithromycin or telithromycin, which can increase the levels and effects of clonazepam. You may need to monitor your blood levels of these drugs and adjust your dose of antibiotics while taking clonazepam.
- Antiretrovirals (HIV medications), such as ritonavir, indinavir or saquinavir, which can increase the levels and effects of clonazepam. You may need to monitor your blood levels of these drugs and adjust your dose of antiretrovirals while taking clonazepam.
- Bupropion (a drug used to treat depression and smoking cessation), which can decrease the levels and effects of clonazepam. You may need to monitor your blood levels of bupropion and adjust your dose of bupropion while taking clonazepam.
- Cimetidine (a drug used to treat stomach ulcers and acid reflux), which can increase the levels and effects of clonazepam. You may need to monitor your blood levels of cimetidine and adjust your dose of cimetidine while taking clonazepam.
- Digoxin (a drug used to treat heart failure and irregular heartbeat), which can increase its levels and effects when taken with clonazepam. You may need to monitor your blood levels of digoxin and adjust your dose of digoxin while taking clonazepam.
- Disulfiram (a drug used to treat alcoholism), which can cause a severe reaction when taken with clonazepam. This reaction can cause flushing, nausea, vomiting, headache, chest pain, palpitations and low blood pressure. You should not take disulfiram within 14 days before or after taking clonazepam.
- Oral contraceptives (birth control pills), which can decrease the effectiveness of oral contraceptives when taken with clonazepam. You may need to use an additional or alternative method of contraception while taking clonazepam.
- Theophylline (a drug used to treat asthma and chronic obstructive pulmonary disease), which can decrease the levels and effects of clonazepam. You may need to monitor your blood levels of theophylline and adjust your dose of theophylline while taking clonazepam.
This is not a complete list of all the possible interactions of clonazepam. Before taking clonazepam, tell your doctor about all the medications, supplements and herbal products you are using or planning to use. Do not start, stop or change the dose of any drug without your doctor’s approval.
Who should avoid clonazepam?
Clonazepam is not suitable for everyone. Some people may have an allergy or intolerance to clonazepam or any of its ingredients. Symptoms of an allergic reaction may include rash, itching, hives, swelling, difficulty breathing or anaphylaxis. If you have ever had an allergic reaction to clonazepam or any other benzodiazepine drug, such as diazepam or alprazolam, do not take clonazepam.
Some medical conditions may also make clonazepam unsafe or ineffective for you. You should not take clonazepam if you have:
