Interaction Effect
Induction or exacerbation of orthostatic regulation disturbances
Interaction Summary
RisperiDONE is a neuroleptic agent which exhibits alpha-adrenergic antagonistic properties that may result in induction of orthostatic hypotension associated with dizziness, tachycardia, and syncope, especially when first initiated. The concomitant use of risperiDONE and antihypertensive medications has caused clinically significant hypotension. The coadministration of clonidine with risperiDONE may result in orthostatic regulation disturbance induction or exacerbation and should be approached with caution.

How To Manage Interaction
The concomitant use of clonidine and neuroleptics, such as risperiDONE, may induce or exacerbate orthostatic regulation disturbances (eg, dizziness, fatigue, orthostatic hypotension) and should be approached with caution.

Risperidone Overview
-
Risperidone is used to treat the symptoms of schizophrenia (a mental illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate emotions) in adults and teenagers 13 years of age and older. It is also used to treat episodes of mania (frenzied, abnormally excited, or irritated mood) or mixed episodes (symptoms of mania and depression that happen together) in adults and in teenagers and children 10 years of age and older with bipolar disorder (manic depressive disorder; a disease that causes episodes of depression, episodes of mania, and other abnormal moods). Risperidone is also used to treat behavior problems such as aggression, self-injury, and sudden mood changes in teenagers and children 5 to 16 years of age who have autism (a condition that causes repetitive behavior, difficulty interacting with others, and problems with communication). Risperidone is in a class of medications called atypical antipsychotics. It works by changing the activity of certain natural substances in the brain.
Clonidine Overview
-
Clonidine tablets (Catapres) are used alone or in combination with other medications to treat high blood pressure. Clonidine extended-release (long-acting) tablets (Kapvay) are used alone or in combination with other medications as part of a treatment program to control symptoms of attention deficit hyperactivity disorder (ADHD; more difficulty focusing, controlling actions, and remaining still or quiet than other people who are the same age) in children. Clonidine is in a class of medications called centrally acting alpha-agonist hypotensive agents. Clonidine treats high blood pressure by decreasing your heart rate and relaxing the blood vessels so that blood can flow more easily through the body. Clonidine extended-release tablets may treat ADHD by affecting the part of the brain that controls attention and impulsivity.
-
High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.
