Summary
Clonidine is used to treat high blood pressure, which is also known as hypertension. It is also prescribed for attention deficit hyperactivity disorder, which is a condition affecting focus and behavior, and certain pain conditions. It can be used alone or with other medications to manage these conditions effectively.
Clonidine works by stimulating alpha-2 adrenergic receptors in the brain, which are parts of the nervous system that help control blood pressure. This action reduces nerve signals that tighten blood vessels, relaxing them and lowering blood pressure. It helps manage high blood pressure and can also be used for ADHD and certain pain conditions.
Clonidine is usually taken as a tablet by mouth, twice daily, in the morning and at bedtime. The starting dose for adults is typically 0.1 mg, which may be adjusted by a doctor based on individual needs. It can be taken with or without food, and the tablet should be swallowed whole.
Common side effects of Clonidine include drowsiness, which means feeling unusually sleepy, dry mouth, which is a lack of saliva, and constipation, which is difficulty in having bowel movements. These effects vary from person to person and are usually mild.
Clonidine can cause low blood pressure, which is when blood pressure drops too low, leading to dizziness or fainting. It should not be stopped suddenly, as this can cause a rapid increase in blood pressure. People allergic to Clonidine or its ingredients should not use it.
