Clonidine
About Clonidine
Clonidine is used in the management of high blood pressure. Besides this, Clonidine is used alone or in combination with other medicines to treat attention deficit hyperactivity disorder (ADHD) in children above 6 years. Clonidine may also be used to prevent migraine attacks and similar types of headaches. It is also used to prevent hot flushes, which may occur in women during menopause. Clonidine may also be used to treat post-operative pain, neuropathic pain, and chronic pain.
Clonidine contains 'Clonidine' that relaxes and widens the blood vessels, making it easier for the heart to pump blood to all parts of the body. This, in turn, helps in decreasing the raised blood pressure and the risk of having a heart attack or stroke in future. Additionally, Clonidine helps in treating attention deficit hyperactivity disorder (ADHD) by affecting the part of the brain, which controls impulsivity and attention.
You are advised to take Clonidine for as long as your doctor has prescribed it for you, depending on your medical condition. In some cases, you may experience certain common side effects, such as headache, tiredness, dry mouth, weakness, nausea, vomiting, diarrhoea, and constipation. Most of these side effects do not require medical attention and will resolve gradually over time. However, it is recommended that you speak to your doctor if you experience these side effects persistently.
Regular monitoring of blood pressure, electrolyte levels, and kidney functioning is advised while taking Clonidine. Consult your doctor if you are pregnant or breastfeeding. Clonidine is not recommended for children unless prescribed by a doctor. Avoid alcohol consumption while taking Clonidine as it might increase certain side-effects. Keep your doctor informed about all the medicines you are taking and your health condition to rule out any unpleasant side effects.

Patients Concern
Disease/Condition Glossary
High blood pressure (hypertension): It is a condition in which the blood exerts increased pressure on the walls of blood vessels, leading to hypertension. This condition can lead to hardened arteries (blood vessels), decreasing the blood and oxygen flow to the heart. Raised blood pressure can cause chest pain (angina) and heart attack (when the blood supply to the heart is blocked). Additionally, high blood pressure also causes brain damage (stroke) and kidney failure. Symptoms of high blood pressure include headache, dizziness, nose bleed, changes in vision, chest pain, weakness and dyspnoea (shortness of breath). However, most of the time, there are no signs or symptoms of hypertension.
Attention Deficit Hyperactivity Disorder (ADHD): It is a mental health disorder that causes hyperactivity and impulsive behaviour. People with ADHD have trouble focusing their attention on a single task or sitting still for a longer time. It often begins in childhood and lasts through adulthood. Symptoms of ADHD include limited attention and hyperactivity.
Migraine: Migraine is a neurological condition which is characterised by an intense, debilitating headache. Hormonal changes, stress, lack or excess of sleep, bright lights, loud sounds, and certain foods and drinks can trigger migraine headaches. Symptoms of migraine include throbbing pain in one particular area with varying intensity, nausea, vomiting, numbness or tingling sensation, difficulty speaking, and sensitivity to sound and light.
Hot flushes: Hot flushes are one of the most common symptoms of menopause and perimenopause. Symptoms include profuse sweating and a sudden feeling of warmth, generally over the face, chest, and neck.
Pain: It is a symptom triggered by the nervous system, causing uncomfortable sensations in the body. Pain may be dull or sharp; it might be constant or may come and go. The common causes of pain include headache, muscle strain, cramps, cuts, bone fractures, arthritis, stomach aches, and certain medical conditions.
