Klonopin Uses, Side Effects & Addiction Symptoms

What is Klonopin?

Klonopin (Clonazepam) is a prescription benzodiazepine and sedative approved to treat panic disorder, with or without agoraphobia. It also helps prevent and control seizures, especially in those with epilepsy. Lastly, benzodiazepines are also commonly used to treat insomnia (sleeping difficulties) and alcohol withdrawal.

Klonopin pill

Klonopin is a long-acting benzo that can stay in the body for up to 50 hours. The medication is a yellow crystalline powder that comes in tablet form. It is usually taken orally in multiple doses throughout the day.

Panic disorder is when a person experiences sudden and frequent episodes of intense fear. Many people with this disorder continuously fear because panic attacks can occur at any time. This leaves them feeling anxious and hopeless. Symptoms of these attacks include shortness of breath, chest pain, heart palpitations, dizziness, nausea, and sweating.

Depending on your age and reason for the prescription, standard doses of Klonopin vary. For example, typical doses for seizure disorders and panic disorder are as follows:

  • For adults with seizure disorders, the dose should not exceed 1.5 mg a day and is typically separated into three doses. However, the maximum daily dose is 20 mg.
  • For pediatric patients with seizure disorders, including infants and children, the usual dose is between .01 and .02 mg a day and is separated into two or three doses.
  • The first dose for adults with panic disorder should be 0.25 mg a day. After about three days of use, the dose will increase to 1 mg a day.
  • Elderly patients should begin with very low doses of Klonopin. They must also be monitored by a medical professional.
  • Children under 18 years of age typically do not take this medication for panic disorder.

Klonopin's onset of action occurs within an hour of taking the drug. This means that a person will start feeling the desired effects of Klonopin within this period of time. These effects will be felt for approximately 6 to 24 hours. 

Klonopin typically produces feelings of pleasure which may include:

  • Euphoria
  • Relaxation of mind and body
  • Slowing of thoughts
  • Calmness
  • Reduced tension in the muscles
  • Absence of agitation
  • Drowsiness, stimulating a person to fall asleep faster and longer

Klonopin is extremely addictive if taken long-term.

Is Klonopin Addictive?

All benzodiazepines (benzos), which are a class of psychoactive drugs, have highly addictive properties. They also have a significant risk of tolerance and dependence. However, Klonopin is one of the most addictive benzos that is commonly abused for its sedative effects.

Addiction to Klonopin can be very dangerous. People who take this medication have a higher risk of suicidal thoughts and behaviors and may notice extreme mood changes. Increased aggression, hostility, poor sleep, and irritability are also common.

Lastly, abusing Klonopin may lead to allergic reactions and fatal overdoses. This is because Klonopin is a central nervous system (CNS) depressant, which means it slows down your heart rate and breathing. When taken in large doses, coma or death can occur.

If you experience the following symptoms, they could indicate a more serious problem, such as an overdose:

  • Worsening or more frequent seizures
  • Shallow breathing
  • Slurred speech
  • Impaired memory
  • Fluttering in your chest
  • Severe drowsiness and dizziness
  • Involuntary eye movements
  • Low attention span
  • Unsteadiness and lack of coordination

Klonopin Drug Interactions

Combining Klonopin with other drugs, such as opioids, can result in serious health complications because extreme sedation can happen. Possible complications include respiratory depression, coma, and death.

In addition, some people snort cocaine or take other stimulants to counteract Klonopin’s sedative effects. On the other hand, others drink alcohol to enhance the calming effects of the medication. All of these drug combinations are extremely dangerous and can result in fatal outcomes. In particular, drinking alcohol while taking Klonopin can slow down your CNS to the point where you stop breathing altogether.

Klonopin Addiction and Withdrawal Symptoms

Common signs of a Klonopin addiction include persistent cravings for the drug and continuing to use it despite knowing the negative consequences. You may also develop financial or legal issues, lose interest in once enjoyable activities, and want to quit but not be able to do so.

If you suddenly stop taking the medication after using it long-term, you may also experience withdrawal symptoms. These include:

  • Seizures
  • Tremors
  • Muscle cramping
  • Nausea and vomiting
  • Intense anxiety
  • Psychosis
  • Profuse sweating
  • Irritability
  • Mood swings
  • Heart palpitations
  • Insomnia
  • Increased blood pressure

Side effects of Klonopin withdrawal can be deadly (due to the risk for seizures), so you should not quit without professional medical supervision.

Klonopin Addiction Treatment Options

Klonopin is habit-forming, so psychological addiction and physical dependence develop quickly. If you or a loved one is addicted to this medication, you should seek treatment immediately to prevent overdose and death. Medical detox, medications, and behavioral therapy are all necessary to withdraw from Klonopin safely and effectively.

Common medications that aid in the Klonopin withdrawal process include:

  • Serotonin reuptake inhibitors — including Prozac and Paxil, which help manage the symptoms of withdrawal.
  • Anticonvulsant medications — such as carbamazepine and Tegretol, which help control seizures during withdrawal.
  • Melatonin — a naturally-occurring hormone that assists in regulating the sleep-wake cycle.

Beyond detox and medications, there are other forms of treatment for drug abuse. Behavioral therapy and counseling also effectively treat benzodiazepine addictions. Cognitive-behavioral therapy (CBT) helps people manage stress, triggers, expectations, and behaviors related to Klonopin after the withdrawal detox is complete.

Klonopin is challenging and dangerous to quit without medical supervision. Find treatment today.
