Does Catapres (Clonidine) Work for People With Anxiety?

What does it mean to have anxiety?

According to the American Psychological Association (APA) anxiety is “an emotion characterized by feelings of tension, worried thoughts and physical changes like increased blood pressure. Knowing the difference between normal feelings of anxiety and an anxiety disorder requiring medical attention can help a person identify and treat the condition.

The duration or severity of an anxious feeling can sometimes be out of proportion to the original trigger, or stressor. Physical symptoms, such as increased blood pressure and nausea, may also develop. These responses move beyond anxiety into an anxiety disorder.

The APA describes a person with anxiety disorder as “having recurring intrusive thoughts or concerns.” Once anxiety reaches the stage of a disorder, it can interfere with daily function.

While a number of different diagnoses constitute anxiety disorders, the symptoms of a generalized anxiety disorder (GAD) will often include the following:

•          restlessness, and a feeling of being “on-edge”

•          uncontrollable feelings of worry

•          increased irritability

•          concentration difficulties

•          sleep difficulties, such as problems in falling or staying asleep

While these symptoms might be normal to experience in daily life, people with GAD will experience them to persistent or extreme levels. GAD may present as vague, unsettling worry or more severe anxiety that disrupts day-to-day living.

What is Catapres?

Clonidine was patented in 1961 and came into medical use in 1966. The US Food and Drug Administration (FDA) approved clonidine hydrochloride, 0.1-mg, and 0.2-mg, extended-release tablets (Kapvay; Shionogi Inc) alone or with stimulants for the treatment of attention-deficit/hyperactivity disorder (ADHD) in pediatric patients aged 6 to 17 years.

How Catapres (Clonidine) works

Clonidine is in a class of medications called centrally acting alpha-agonist hypotensive agents.
