Klonopin is a drug that is used to treat panic disorders and seizures in patients. It is taken orally in tablet form. The generic name for Klonopin is clonazepam.

Klonopin is classified in the benzodiazepines group of medication. These are classified as anxiolytic depressants and include drugs such as Valium, Xanax, Ativan and Librium. All are used to treat anxiety, sleeplessness, hyperactivity in the brain and seizure disorders. Benzodiazepines need to be taken under the supervision of a doctor.

Prescriptions for Klonopin are widely filled across the United States. In 2009 alone, 24.4 million clonazepam prescriptions were filled according to IMS Health. Its widespread availability makes Klonopin one of the most common prescription drugs used illegally. In 2009, 20.4 million people over the age of 12 admitted to misusing benzodiazepines, according to a study conducted by the National Survey for Drug Use and Health (NSDUH). The misuse of the medication have lead all benzodiazepines to be classified as schedule IV depressants in the Controlled Substances Act.

Klonopin Long-Term Effects

Tolerance is a long-term effect of Klonopin that is a cause for concern. As people use Klonopin for a period of time, they will develop what is called a tolerance for the drug. Tolerance is the body getting used to the set amount taken and needing more over time to get the same effect. Drug tolerance is extremely dangerous as overdose risk rises as tolerance rises. Never take more than your prescribed dose of any medication, as overdose can lead to serious injury or death. Signs and symptoms of overdose in Klonopin users include:

  • Slow reflexes and slow reaction times.

Klonopin Withdrawal Treatment

Like all benzodiazepine medications, withdrawal after a lengthy period of dependence can be quite uncomfortable but, more importantly, can constitute a medical emergency. On the mild end of the spectrum of withdrawal symptoms are digestive upset, insomnia and mild rebound anxiety. More serious symptoms include marked agitation, delirium and seizure activity. You or your loved one may already feel anxious about not taking the medication before withdrawal begins, but the potential dangers of sudden withdrawal necessitate close supervision throughout the process. This can be overwhelming for some, but medically assisted detox and withdrawal provides the safest, most comfortable way to taper off the medication, and begin a period of recovery.

The treatment for Klonopin dependency will begin with admission into a detox center, rehab center or other treatment center. Many treatments exist for detox, counseling, rehabilitation and education. There is an option for everyone. If you need help finding treatment for you or a loved one, call 1-888-744-0069.

You or your loved one will begin the process by detoxing under the care of a medical profession. During this time you or your loved one will experience withdrawal symptoms that will be treated to keep you or your loved one comfortable. When your body is free of Klonopin, a qualified health care provider will further evaluate your underlying anxiety, and make non-benzodiazepine treatment recommendations for it moving forward. For example, some antidepressants have been proven to be better at treating anxiety in the long term than benzodiazepines according to a study published in Psychiatric Annals.

In treatment you or your loved one will identify the behaviors that are associated with the addiction and learn that changing those behaviors will lead to recovery and sobriety. A combination of therapies will be used such as cognitive-behavioral therapy, family counseling and motivational interviewing. Therapy will help your or your loved ones acknowledge, understand and move beyond the addiction into recovery.
