Is Clonidine a Controlled Substance?


Is Clonidine a Controlled Substance?

Clonidine, a medication prescribed for various conditions, raises questions about its classification. While effective for treating high blood pressure, ADHD, and menopausal symptoms, some might wonder: is clonidine a controlled substance?

The answer is no. Clonidine is not classified as a controlled substance by the Drug Enforcement Administration (DEA) in the United States. Controlled substances are drugs with a high potential for abuse and dependence. They are placed into five schedules based on their potential for abuse, accepted medical use, and safety. 

So, why isn’t clonidine considered a controlled substance? Through this blog, let’s delve deeper into understanding its legal status, medical uses, the potential for abuse, regulatory measures, its properties, and the factors that determine controlled substance classification.

Understanding Clonidine

Clonidine belongs to a class of medications called centrally-acting alpha-2 adrenergic agonists. It works by stimulating specific receptors in the brain stem, decreasing nerve impulses sent to the body. This results in the relaxation of blood vessels and a reduction in heart rate, ultimately lowering blood pressure, which is suitable for understanding whether is clonidine a controlled substance.

Clonidine comes in multiple formulations, such as tablets, patches, and injections, catering to diverse medical needs. Its prescription spans various conditions, including:

  • High blood pressure (hypertension):

This is the primary use for clonidine. It helps manage blood pressure by relaxing blood vessels and lowering heart rate.

  • Attention deficit hyperactivity disorder (ADHD):

Clonidine can help reduce hyperactivity and impulsivity in some children with ADHD. It’s often used in conjunction with stimulant medications to manage side effects like insomnia.

  • Menopausal symptoms:

Clonidine is effective in mitigating hot flashes, a prevalent symptom experienced during menopause, by regulating the body’s temperature control mechanisms.

  • Opioid withdrawal:

Clonidine can help manage some symptoms of opioid withdrawal, such as anxiety, sweating, and tremors.

Factors Determining Controlled Substance Classification

When determining whether a drug should be classified as a controlled substance, the DEA evaluates various criteria, including its potential for abuse, accepted medical use, and safety concerns. These considerations play a pivotal role in answering the question, “Is clonidine a controlled substance?” such as:

  • Potential for abuse:

This refers to the likelihood of someone misusing the drug to experience a pleasurable effect or to achieve a sense of euphoria. Drugs with a high potential for abuse are more likely to be placed on a higher schedule.

  • Accepted medical use:

Drugs with currently accepted medical use in treatment in the United States are less likely to be placed on a higher schedule.

  • Safety:

The DEA also considers the safety profile of the drug, including its potential for addiction, overdose, and other adverse effects.

Why Isn’t Clonidine Controlled?

Clonidine has a low potential for abuse compared to other medications. It doesn’t produce a significant feeling of euphoria or intoxication, making it less attractive for misuse. Additionally, clonidine has a well-established role in treating various medical conditions.

While dependence on clonidine can occur with long-term use, it’s not typically associated with the intense cravings and withdrawal symptoms seen with highly addictive drugs. This, combined with its safety profile, contributes to its classification outside the controlled substances classification, a factor in determining whether is clonidine a controlled substance or not.

Important Considerations with Clonidine

Despite not being a controlled substance, clonidine use requires caution. Here are several crucial reminders regarding the query “Is clonidine a controlled substance“:

  • Prescription medication:

Clonidine is only available by prescription from a doctor. It’s crucial to follow your doctor’s instructions for dosage and duration of use.

  • Potential side effects:

Clonidine can cause side effects such as dizziness, drowsiness, dry mouth, and constipation. It’s important to discuss these with your doctor and be aware of potential interactions with other medications you’re taking.

  • Sudden withdrawal:

Stopping clonidine abruptly, especially after long-term use, can lead to rebound hypertension, a sudden increase in blood pressure. It’s essential to taper off the medication under your doctor’s supervision.

Use of Clonidine for Mental Health Conditions

While is clonidine a controlled substance is not the only concern as it isn’t directly used to treat a specific mental illness. However, it can help manage some symptoms associated with certain mental health conditions. Here’s a breakdown that follows:

  • ADHD:

Clonidine can be used as an adjunct medication for Attention Deficit Hyperactivity Disorder (ADHD), particularly in adults, to help reduce hyperactivity and impulsivity. It’s sometimes used alongside stimulant medications to manage side effects like insomnia.

  • Tourette Syndrome:

Although not a primary treatment, clonidine can help manage some of the tics associated with Tourette Syndrome.

  • Anxiety:

The calming effects of clonidine can be beneficial for managing anxiety symptoms in some cases. However, it’s not a first-line treatment, and other medications are typically preferred.

  • PTSD (Post-traumatic stress disorder):

Clonidine has shown promise in alleviating nightmares, which are prevalent among individuals grappling with PTSD. Its ability to modulate certain neurotransmitters in the brain may contribute to this therapeutic effect, offering relief to those afflicted by the disruptive and distressing nature of PTSD-related nightmares.

It’s crucial to remember whether or not is clonidine is a controlled substance, as it is prescribed by a doctor based on the specific needs and diagnosis of an individual. While it can help manage some symptoms associated with mental health conditions, it’s not a cure for any mental illness.


How does clonidine make you feel?

Some individuals may experience drowsiness or diminished alertness upon taking clonidine, particularly when initiating treatment or adjusting the dosage. These effects are more prevalent during the initial stages of medication intake or dosage escalation.

Who cannot take clonidine?

Clonidine may not be appropriate for certain individuals. Before using clonidine, inform your doctor if you have a history of allergic reactions to clonidine, its components, or other medications, or if you are pregnant, planning to conceive, or breastfeeding.

Is clonidine just like Klonopin?

Clonidine and Klonopin serve distinct purposes despite some similarities in their applications. Clonidine is typically regarded as having a lower risk of abuse compared to Klonopin, yet both medications possess valid medical indications.


In conclusion, while the question “Is clonidine a controlled substance?” prompts consideration of its regulatory status, it is evident that clonidine does not fall under the classification of controlled substances according to prevailing regulations. Despite this, vigilance is warranted regarding its potential for misuse and dependency. Clonidine’s therapeutic versatility underscores its importance in clinical practice. Its comparatively lower risk of abuse, attributed to its sedative rather than euphoric effects, contributes to its exemption from controlled substance status.

However, healthcare providers must remain vigilant, emphasizing responsible prescribing practices and patient education to mitigate risks. By fostering awareness and understanding of clonidine’s benefits and limitations, clinicians can navigate its usage effectively, ensuring safe and appropriate treatment for those who stand to benefit from its therapeutic effects.
