Understanding Klonopin (clonazepam) dosage
Klonopin (clonazepam) is prescribed in varying doses that can depend on factors including: [1]
- Age and weight
- The condition being treated
- Physical health
- Response to the medication
- Other medications
Because people can have differing responses to medications, two people with the same condition may require significantly different doses to manage their symptoms. When Klonopin is prescribed, the doctor will assess the individual and these specific factors and recommend a daily dose that is suitable and individualized.
Klonopin dosing guidelines by condition
Klonopin is prescribed to adults and children to treat seizure disorders, and to adults only to treat panic disorder. Dosing guidelines vary depending on the age group and condition being treated. [1]
Adults with seizure disorders: Initial dose of 0.5-1.5 mg, taken three times per day. The daily dose can be increased by 0.5-1 mg every three days until symptoms are managed, up to a maximum daily dose of 20 mg.[1]
Adults with panic disorder: Initial dose of 0.25 mg, taken twice per day for three days, then 0.5 mg twice a day. The dose can be increased if necessary to a maximum of 4 mg per day.[1]
Children with seizure disorders (Up to the age of 10 or up to 30 kg body weight): The initial dose should be 0.01-0.03 mg per kg per day, in two or three divided doses. Every three days, doses can be increased by 0.25-0.5 mg until symptoms are controlled, a daily dose of 0.1-0.2 mg per kg has been reached, or side effects prevent further increases.[1]
What is the maximum daily dose of Klonopin?
The maximum daily dose of Klonopin for adults with seizure disorders is 20 mg per day. For adults with panic disorder, the maximum is 4 mg per day. For children with seizure disorders, the maximum is 0.1-0.2 mg per kg of body weight per day.[1]
Dosage considerations for different populations
Doses may need to be adjusted for certain people. For example: [1][2]
- Over 65 years old: Benzodiazepines can be dangerous for older adults and may cause a risk of falls, cognitive dysfunction, and delirium. In some cases, it may be deemed medically necessary for an older adult to be treated with Klonopin for seizure disorders or severe anxiety conditions. If so, they should be closely monitored and given a reduced dose.
- Pregnant or breastfeeding: Using Klonopin while pregnant may cause risks to the development or birth of the child. Similarly, Klonopin may be passed to a breastfeeding infant through the milk, which can cause adverse effects. The benefits and risks should be considered before commencing Klonopin treatment in these cases, and doses may need to be reduced if treatment is necessary.
- Liver or kidney impairments: Klonopin is metabolized by the liver and eliminated by the kidneys. Because of this, people with liver or kidney impairments may require a reduced dose to prevent excess accumulation in the body.
Side effects related to dosage
Side effects of Klonopin may be common at the start of treatment or when increasing the dose. These effects will be alleviated within a few weeks. In some cases, side effects can occur that are serious, prolonged, or life-threatening, particularly when using large doses.
Common side effects can include: [1][2]
- Fatigue and lethargy
- Sedation and drowsiness
- Feeling unsteady and dizzy
- Impaired movements and motor skills
Side effects that are more rare, potentially serious, and that should be reported to the prescribing clinician include: [2]
- Extreme changes in behavior and mood, including depression, anxiety, suicidal thoughts, aggression, or psychotic symptoms such as hallucinations
- New or increased frequency of seizures
- Memory impairments
- Difficulties with walking, speaking, coordination, or eye movements
- Paranoia
- Breathing issues
- Heart issues
- Loss of consciousness
- Delirium
Klonopin overdose
Taking a large dose of Klonopin can cause a risk of overdose. Additionally, if Klonopin is combined with other drugs, particularly opioids, the risk of overdose may be higher.
Signs of Klonopin overdose include: [1][2]
- Severe drowsiness
- Confusion
- Impaired movements and reflexes
- Slurred speech
- Slowed or stopped breathing
- Wheezing, trouble breathing, chest pain
- Extreme changes in heart rate or blood pressure
- Cardiac arrest
- Loss of consciousness
In the event of a Klonopin overdose, call 911 immediately. Urgent and life-saving medical care may be necessary. This can include the management of heart and breathing issues and the administration of flumazenil, a benzodiazepine receptor antagonist. [2]
Interactions and precautions
Klonopin causes central nervous system (CNS) depressant effects. As such, combining Klonopin with opioids can increase the risk of oversedation, breathing issues, loss of consciousness, or death. [1]
Additionally, combining Klonopin with other benzodiazepines, alcohol, kratom, antidepressants, antipsychotics, anticonvulsants, and antihistamines can increase sedative effects. [2]
Some medications impact the effectiveness of Klonopin, increasing or reducing its effects. This includes certain anticonvulsant medications such as carbamazepine and phenobarbital, and certain antibiotic or antiviral medications such as macrolides, rifampin, and certain HIV treatment regimens. [2]
Always discuss your current and recent medications with your doctor before commencing Klonopin.
Tapering off Klonopin safely
Klonopin use can cause the development of physical dependence in a short time, sometimes within weeks of use, causing withdrawal symptoms when treatment is discontinued. Withdrawal symptoms may be more likely or more severe if use is stopped abruptly or after prolonged and excessive use. [1]
It is recommended to gradually reduce Klonopin, known as tapering, to help reduce the risk of withdrawal symptoms. This can involve dose reductions of 0.125 mg every three days until complete cessation. Tapering can be slowed or doses increased if severe withdrawal symptoms occur. [1]
People coming off Klonopin should always do so with professional advice and monitoring, as withdrawal symptoms can be severe and sometimes life-threatening. [2]
