Klonopin® Overview 

Klonopin® is an anticonvulsant drug used to treat seizures and panic disorder. It works by enhancing neurotransmitter activity. It’s thought to calm the brain by reducing its sensitivity to stimulation.

What is Klonopin®?

Clonazepam, the generic name for Klonopin®, is a medication prescribed by doctors for seizure and panic disorders. Due to its potential for misuse and dependence, it is a Schedule IV controlled substance. It is FDA-approved for use by children and adults.

Klonopin® comes as both an oral tablet and an oral dissolving tablet. It’s available in the following strengths: 0.5 milligrams (mg), 1.0 mg, and 2.0 mg.

What Is Klonopin®?

Is Klonopin® A Benzo?

Klonopin® is classified as a benzodiazepine, also known as a benzo. Benzos promote the activity of gamma-aminobutyric acid (GABA), lessening anxiety and stress reactions. In turn, this results in fewer panic attacks and seizures in those who take it.

Is Klonopin® Safe To Take?

Klonopin® is a safe and effective medication when taken as directed by a doctor. Side effects range from mild to serious. It’s important not to take Klonopin® without a prescription from a medical professional.

Klonopin® can be harmful when combined with other substances, including alcohol. Tell your doctor and pharmacist if you use any other over-the-counter, prescription, or recreational drugs.

Prolonged use of Klonopin® can increase the risk of physical dependence and abuse. As such, natural alternatives to Klonopin® should be considered when possible.

Klonopin® Uses

Klonopin® is FDA-approved for the treatment of certain seizure and panic disorders. When used as directed, it can reduce the frequency of panic attacks and seizures.[1]

Klonopin® For Pain

Klonopin® for pain is an off-label use, meaning it is not technically approved for the treatment of pain. Klonopin® slows stress responses in the CNS, producing a calming effect. Thus it sometimes reduces pain.

Klonopin® For Depression

It is generally not recommended to take Klonopin® for depression. For individuals with depression, their symptoms may become worse while taking Klonopin®.

It is important to call the doctor immediately if you experience worsening symptoms of depression or suicidal thoughts while taking Klonopin®. Certain antidepressants may increase your risk of CNS and breathing problems when taken with Klonopin®.

Klonopin® For Anxiety

Klonopin® is not specifically labeled to treat generalized anxiety. However, some doctors prescribe Klonopin® for anxiety that is caused by the anticipation of a panic attack.

The longevity of Klonopin® as a treatment for anxiety varies based on a number of factors, including symptom severity. Dosage may also differ, it’s important to talk to your doctor to learn more.

Klonopin® For Panic Attacks

Doctors often prescribe Klonopin® for panic attacks in adults with or without agoraphobia. Panic disorder is a type of anxiety disorder that is characterized by frequent panic attacks.

These panic attacks make you suddenly feel intense fear that often manifests in physical symptoms that can include:

  • Chest discomfort
  • Rapid heart rate
  • Shaking or trembling
  • Excessive sweating
  • Difficulty breathing
  • Chills, or hot flashes

Klonopin® has proven to be an effective treatment for panic disorder in adults when taken as prescribed.

Klonopin® For Seizures

Klonopin® is an FDA-approved medication used to treat certain seizure disorders, also known as epilepsy. Doctors prescribe Klonopin® for seizures in adults and children.

Seizures result from an interruption in the brain’s normal electrical activity. Symptoms vary widely based on the type of seizure and are sometimes difficult to detect. Klonopin® may help reduce the frequency of atonic, myoclonic, and absence seizures. It is important to take the medication exactly as directed.

Klonopin® For OCD

Taking Klonopin® for OCD is not common, but some individuals have reported relief from their OCD-associated anxiety from the drug.

OCD is a psychiatric disorder that includes repetitive, intrusive thoughts and fears causing unwanted behaviors. This causes distress and anxiety in affected individuals.

Klonopin® For PTSD

Using Klonopin® for PTSD is generally not recommended. While it can be effective in easing PTSD-related episodes of panic and anxiety, it also hinders recovery. Most professionals encourage alternative treatments for PTSD, including therapy.

PTSD is a mental health condition developed after a traumatic event. Similar to panic disorder, it is characterized by intrusive thoughts. However, it differs because it is directly associated with a single or series of specific events.

Klonopin® For Bipolar Disorder

Klonopin® is used as an off-label treatment for bipolar disorder. Clonazepam has been shown to improve bipolar symptoms in controlled studies and case reports. Klonopin® for bipolar disorder is growing in popularity as an alternative to neuroleptics.

Bipolar disorder causes abrupt changes in mood and behavior. You may experience high mood called mania, followed by a low state called depression.

Klonopin® For Flying

Flying is an anxiety-inducing activity for many people. Benzo use is relatively common for travelers experiencing panic episodes before a flight. However, Klonopin® for flying is typically not prescribed due to its longer onset time.

The effects of Klonopin® take about 1 to 4 hours to be noticeable. It is one of the more long-lasting benzos (6 to 12 hours). This is why it’s usually used on a regular basis to treat ongoing anxiety disorders.

Klonopin® For Headache

Doctors rarely prescribe Klonopin® for headaches. In fact, headaches are a withdrawal symptom if you stop taking Klonopin® suddenly. However, if your headaches are directly caused by stress and anxiety, it may indirectly help.

Klonopin® For Sleep and Insomnia

Klonopin® is not approved for the treatment of insomnia and other sleep issues. However, it’s a common off-label use of the drug. When you use Klonopin® for insomnia, you may continue to feel tired the next day since it stays in your body for a long time.

One of the major side effects of Klonopin® is drowsiness. Therefore using Klonopin® for sleep is growing in popularity. Nevertheless, it’s important to use Klonopin® as prescribed by your doctor.

Klonopin® has a black box warning, the most serious warning issued by the FDA. Black box warnings caution medical personnel and consumers of potentially dangerous drug effects.

There is a considerable risk of physical dependence. In as little as 3 to 6 months, the drug has a high likelihood of being misused. Once a dependence has been established, weaning off the drug can be difficult.

Withdrawal must be avoided by gradually tapering off your Klonopin® dosage. It’s extremely important to seek medical help when experiencing withdrawal due to potential life-threatening effects.

Klonopin® Overdose Symptoms & OD Treatment

Taking Klonopin® in a way other than prescribed can lead to life-threatening side effects. The symptoms of Klonopin® overdose include:

  • Extreme drowsiness
  • Confusion or disorientation
  • Slowed reflex time
  • Decreased blood pressure
  • Coma

If you or someone around you is experiencing these symptoms, seek emergency medical help immediately. Klonopin® overdoses can be easily fatal if not treated quickly. 

Klonopin® and Alcohol

It’s crucial to avoid alcohol consumption while taking Klonopin®. Combining the two increases your risk of serious side effects or death. Because alcohol also acts as a sedative, it can interact with Klonopin® to heighten the effects seen from the drug.

Risks include slow, shallow breathing, extreme sleepiness, coma, and death. If you currently consume alcohol or plan to while taking Klonopin®, you should talk to your doctor.

Klonopin® vs. Xanax®

If you’ve discussed benzos as a treatment option with your doctor, they may have mentioned both Klonopin® and Xanax®. These are central nervous system depressants that affect gamma-aminobutyric acid (GABA) in the brain.

Both drugs treat anxiety disorders, including panic disorders, in adults. Klonopin® also treats seizures in adults and children. The effects of Klonopin® last longer, usually a few days, as compared to Xanax®, which only remains effective for a few hours.

Klonopin® is taken on a more regular basis, while Xanax® is typically used as needed.
