Clonidine Hypertensive Crisis Causes and Reviews


What is blood pressure?

Blood pressure is the force of your blood pushing against the walls of your arteries. Each time your heart beats, it pumps blood into the arteries. Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is called diastolic pressure.

Your blood pressure reading uses these two numbers. Usually the systolic number comes before or above the diastolic number. For example, 120/80 means a systolic of 120 and a diastolic of 80.

How is high blood pressure diagnosed?

High blood pressure usually has no symptoms. So the only way to find out if you have it is to get regular blood pressure checks from your health care provider. Your provider will use a gauge, a stethoscope or electronic sensor, and a blood pressure cuff. He or she will take two or more readings at separate appointments before making a diagnosis.

You have high blood pressure if your readings show that

  • Your systolic is 140 or higher OR
  • Your diastolic is 90 or higher

Some providers may consider you to have high blood pressure if you have other heart risk factors and

  • Your systolic is between 130 and 139 OR
  • Your diastolic is between 80 and 89

Blood pressure readings above 180 /120 are dangerously high and require immediate medical attention.

For children and teens, the health care provider compares the blood pressure reading to what is normal for other kids who are the same age, height, and gender.

What are the different types of high blood pressure?

There are two main types of high blood pressure: primary and secondary high blood pressure.

  • Primary, or essential, high blood pressure is the most common type of high blood pressure. For most people who get this kind of blood pressure, it develops over time as you get older.
  • Secondary high blood pressure is caused by another medical condition or use of certain medicines. It usually gets better after you treat that condition or stop taking the medicines that are causing it.
Why do I need to worry about high blood pressure?

When your blood pressure stays high over time, it causes the heart to pump harder and work overtime, possibly leading to serious health problems such as heart attack, stroke, heart failure, and kidney failure.

What are the treatments for high blood pressure?

Treatments for high blood pressure include heart-healthy lifestyle changes and medicines.

You will work with your provider to come up with a treatment plan. It may include only the lifestyle changes. These changes, such as heart-healthy eating and exercise, can be very effective. But sometimes the changes do not control or lower your high blood pressure. Then you may need to take medicine. There are different types of blood pressure medicines. Some people need to take more than one type.

If your high blood pressure is caused by another medical condition or medicine, treating that condition or stopping the medicine may lower your blood pressure.

Clonidine Hypertensive Crisis Reviews

Mon, 07 May 2012

prescribed Clonidine 2 months ago for hot flushes due to the menopause. I am taking 25mcg twice a day as I cnnot tolerate the advised dose of 50mcg twice a day, but this lower dose has stopped the flushes. Infortunately I have been perpetually cold and have become really irritable. Is this a drug reaction or more symptoms of the menopause?

Sun, 22 May 2011

i am feeling drowsy,weak, and my heart is racing. is that suppose to happen?

Wed, 28 Dec 2011

I take only a portion of a 0.1 mg Clonidine once a day. Since I have been taking this medicine, the have been times that my skin feels that needles are sticking in it---this is all over my body. Has anyone else had this happen? I don't know for sure this is from this medicine, but it started shortly after I started taking it.

Mon, 01 Jun 2009
I take 0*1 mg Clonidine for high BP and have the sensation that my esophagus or chest muscles are spasming. Also my heart rate is accelerated. Are these expected side effects of this medication.
Sun, 15 Nov 2009
I just started on Clonidine for excessive sweating of the scalp and face, but also for insomnia. I had to take .3 mg to get sleepy. I woke up this morning with several canker like sores on the inside of my lips. Anyone else had this happen? I also use a cpap machine and am on other medications.

Fri, 30 Jul 2010
head, ears, throat, too tired, hate to take it.....Dr. said it is a nasty pill but still prescribed it. also, constipation/ loose stools. stomach discomfort....leg / foot spasms at night
Fri, 30 Jul 2010
I find this medication terrible. I dont know about anyone else but I have found that my body has become addictived to this drug. I have only been on this drug since June 18, 2010. I am on the patch 2mg plus one 1 mg tablet 2x per day (total of 4mg) If I do not take this mediction exactly within one hour before it wears of I start to go trough withdrawls. My head get tight my body starts to shake and I start to have a feeling of doom.When this first happen to me I went to the Emergency Room because I did not know what was happening to me. They discharged me because My blood pressure was not that high. Lucky for me My doctor's office was accross the street. I went to see him. He told me that this was one of the side effects of the drug. I told him that I could not live this way. He said this feeling would eventually go away but I had to stay on this drug because when you dont take this drug your blood pressure could spike very high. I was devastated to find that I was taking a drug that could potentially kill me if not taken timely.I have told the doctor that he had to find a way to get me off this medication. I can not function on this med. My vision is getting worse, I have difficulty concentrating, I am extremely aggitated and nervous all the time not to mention that I am so tired I can barely walk a block. I recently spoke with two different doctors who told me that I should not have been put on this med alone. I am so frustrated I dont know what to do. No one seem to be able to help me. Am I doomed to be this sick the reat of my life or is there something that can be done. Sincerely, Hopeless
