Definition

Clonidine belongs to a class of drugs called central alpha-adrenergic agonists. In the United States, clonidine tablets are sold under the brand name Catapres and clonidine skin patches are sold under the brand name Catapres-TTS. The tablets are also available generically. There is also an injectable form that is administered directly into the spinal cord for the treatment of postoperative pain.

Purpose

Clonidine tablets and patches are approved by the United States Food and Drug Administration (FDA) for the treatment of high blood pressure. However, clonidine has been found to be useful in the treatment of alcohol, opiate, and nicotine withdrawal syndromes, attention-deficit/hyperactivity disorder (ADHD), and Tourette's syndrome, one of the tic disorders .

Description

Clonidine was synthesized in 1960s and was initially tested as a nasal decongestant. In the United States, clonidine was first used to treat hypertension although it has also been investigated for treatment of different neuropsychiatric disorders. Clonidine works on specific nerve cells in the brain that are responsible for lowering blood pressure, slowing heart rate, and decreasing the body's reaction to the withdrawal of chemicals like alcohol, opiates, cocaine, and nicotine. Because of this, clonidine is often used to treat the symptoms of drug, alcohol, and nicotine withdrawal.

Clonidine is beneficial in opiate withdrawal because it treats symptoms that are commonly associated with that condition (watery eyes and nose, diarrhea, irritability). For this condition, clonidine is often used alone. For the treatment of alcohol withdrawal, clonidine is usually combined with benzodiazepine tranquilizers such as Librium, Valium, Xanax, or Ativan.

Several studies of treatment for smoking cessation showed patients treated with clonidine had decreased nicotine craving. Clonidine skin patches appear to be more effective than tablets in this condition. Both dermal patches and tablets are effective in the treatment of Tourette's syndrome and ADHD.

Clonidine tablets are available in 0.1-mg, 0.2-mg, and 0.3-mg strengths. Clonidine skin patches are available in 0.1-mg, 0.2-mg, and 0.3-mg per day patches. Each patch lasts seven days.

Recommended dosage

Dosages of 0.4–0.6 mg have been used for the treatment of alcohol withdrawal. Total daily dosage for the treatment of opiate withdrawal range between 0.5 and 1.4 mg, depending on the stage as well as the severity of withdrawal symptoms. If the clonidine patch is used to treat nicotine withdrawal symptoms, dosages that deliver 0.1–.2 mg daily are used. For oral therapy (tablets), a total dosage of 0.2–0.4 mg daily is taken in divided doses.

Pediatric doses of clonidine are calculated based on the child's body weight. Clonidine dosage for ADHD in children is 5 micrograms per kilogram of body weight per day orally in four divided doses. Children who require a daily dosage of 0.2 mg usually can use the 0.3 mg dermal patch. If ADHD is associated with sleep disturbances, low to moderate doses of clonidine can be taken at bedtime. Oral doses in children with Tourette's syndrome range from 3 to 6 micrograms per kilogram of body weight per day divided into two to four even doses.

Precautions

Clonidine should not be used by people who have a known allergy to this drug. If a person has underlying depression, clonidine should be used with caution and under close physician supervision.

Clonidine should not be abruptly withdrawn but rather, slowly decreased over several days to avoid withdrawal symptoms. Withdrawal symptoms include increases in blood pressure, irritability, nervousness, insomnia , and headache. Because of the possibility of withdrawal, clonidine should not be used in patients who are unwilling or unable to follow the prescribing information.

Clonidine should be used only with caution and close physician supervision in patients with chronic renal failure, coronary artery disease, and in patients with preexisting eye problems. Often people with kidney disease should take a reduced dosage. Clonidine should not be used by pregnant women, except in the rare case where the benefits of taking clonidine outweigh the risks to the developing fetus.

Side effects

The most common side effect associated with clonidine is dizziness associated with sudden changes in position such as standing up rapidly. In order to avoid this, atients should stand up slowly. People using the dermal patch may develop rash, hair loss, a burning sensation on the skin, or other skin irritations where the patch is applied. Switching to tablets may not completely eliminate these skin problems, however.

Clonidine can cause dry mouth, constipation, nausea, daytime sleepiness, weakness, and lethargy. These side effects may take several weeks to disappear. In some cases, these side effects can be eliminated with dosage readjustment. In addition, clonidine may cause eye dryness, loss of sex drive, and decreased sexual activity.

If patients experience weight gain in the beginning of therapy, they can expect this side effect to decline over a period of several days to weeks.

Interactions

Clonidine's blood pressure-lowering effects may be enhanced by other drugs that lower blood pressure. Conversely, the blood pressure-lowering effects of clonidine may be negated by many antidepressants.

My son has been diagnosed with possible early stages of ADHD. He is currently 7 years of age and has been taking 5 mg doses of CLONIDINE since 2008. Prior to taking this he was just fine; calm, cool and collective. After losing hsi father to incarceration in late 2008, he began to experience a slight case of insomnia (unable to get to sleep at night). Once this began, along with epiesodes of outbursts in anger, stuttering to get words out, etc. he was taken into the doctor and then diagnosed with juvenille ADHD and tyhen prescribed 5mg CLONIDINE to be taken daily at night to calm his body enough to sleep. Question: I do not desire my son to become so dependant (as he already is) on the drug that he becomes to be a pill popper. So how o I ween he from the pill and if so what may become the ultimate results.

To the parents of juveniles taking this medicine. MY 8 yo son has been taking this medicine since he was 7yo roughly 9 mos. He was given Clonodine to help him sleep.He has ADHD and doesnt/can't wind down and fall asleep on his own til 1-3 am without it. This medicine initially was a life saver for my son and myself. Lately it seems like the .1mg dose isn't enough (he was prescribed up to .2mg) I hesitate giving him the higher dose because he will complain of dizziness. And I also worry about over dosing him he only weighs 58lbs.The only strange side effect that I have seen him have with these meds is a sleep walking/talking. He will appear to be awake (eyes open) talking , walking but makes no sence what so ever. I do feel that the benefits outweigh any negatives their may be though. Best of Luck

I have a 4 year old son who just started taking this medication for the first time. For ADHD and other reasons. However it kicked in right away and he was sitting very still and quite plus he fell asleep very quickly. Is that normal? What side affects does this medicine have on children? Does it effect the brain? Will it hurt my child? Will it do more harm then good? Will he be drowsy the next day from this medicine?

I am currently on Percocet&Fentanyl patches. Should I take clonidine with this? I was given this for withdrawal, which no longer pertains to me. Thank You.

My 8 yr old is currently taking .15mg of clonidine split into three daily doeses for ADHD, Tourettes and ODD. He was taking stimulants prior to clonidine and was very thin, but after he began taking this medication, it's been about a month, he has gain about 10 lbs. Has anyone else experienced a rapid weight gain like this? He is very active, and although he is eating better now it still seems like an awful lot of weight for and 8 year old to gain is such a short amount of time.

My son is 16 and was diagnosed with a Mood Disorder, OCD, ADD, & ODD since he was 6, he is also developmentally delayed & now has Anxiety. He has tried so many meds and is very sensitive to the side effects. He was just put on Clonadine and he says that he feels that this helps him, however it does make him very tired and he looks "drugged" up basically. I know that it takes time for the body to get used to the dosage, however, I will continue to monitor him carefully. But I wanted to tell the parents of children with ADHD, ADD & ODD that have been diagnosed at a very young ages, please also look at their diets, & what's going on at home. I say this because until an Master Level Therapist came in the home, I could not see how I contributed to my son's behavior. It was over time that I was shown how our behaviors (mine & his dad's) would affect my son and then result in his negative behavior or to display typical ADD & ODD behaviors. I also learned how certain foods are "triggers" and can intensify symptoms. Also unknown allergies cause behavioral symptoms. I am not a doctor, I am only speaking from personal experience and trial & error. Good luck to you all, our journey is a long and trying one.

After 2 back surgeries that were 9 months apart, I became addicted to prescription pain killers. Oxycodone, oxycodine, OxyContin, hydrocodone...you name it. Not only did it relieve the pain, but the euphoria inexperienced was a wonderful side effect. Quitting their usage was difficult because my body could not produce dopamine (a pleasure chemical in the brain) on its own since it was artificially stimulated by the drugs. Most everything that I formerly enjoyed no longer gave me pleasure such as fishing, hunting, playing music, and other hobbies because I didn't receive the dopamine that should have been naturally produced. I no longer cared to do any of those activities, became sedintary, and quite frankly didn't give a sh-t about anything. I tried anti-depressants with no luck. My doctor then prescribed clonidine and within a few week I began to feel better. A month later my doctor doubled my dosage to 0.4 mg. A month later I started to enjoy golfing, I picked up my guitar again, and started taking better care of myself, my business, and my home. I now feel the best I've felt in over a year and life is good. We are now about to ween my off the Lamictal that wasn't working anyway. This is just my personal experience and not a recommendation for anyone. I hope this gives some insight to those that are experiencing similar disappointments and frustrations.

My 3 yo son was just diagnosed with autism. The therapists recommended this medication for him, but I'm not so sure about it. I dont want him to get any clumsier, be drowsy, walk around like a zombie, or become dependent on anything that could cause withdrawel symptoms. I would much rather deal with a few tantrums and some hyperactivity.

My 4 1/2 year old daughter was diagnosed at 2 1/2 years old with autism and diagnosed a month ago with ADHD. She has had substantial sleep issues starting at 3 years old, and we have successfully been using clonidine for almost a year now. She weighs 38 lbs now, and we are giving her 0.1 mg in the evening. Her sleep is improved, but not perfect. Clonidine seems to have a "knockout" effect 40 min after taking it, but she is well rested in the morning. We tried a dosage of 0.15 and 0.2mg per night, but those were too much and left her groggy in the morning. Our physician has described this as a very safe drug, and we have been happy with it. We also suspect that there has been some carryover effect into the daytime with improved focus (drug mostly worn off by the morning, but not completely), which makes some sense since this is also prescribed as an ADHD medication.

My has been diagnosed with ADHD at the age of 5. He is now 6 1/2 yrs. I believe he is really ADD. He is not really a hyper type of kid but rather a pleasure to his teachers with behavior not being a problem but has a hard time focusing especially when it comes to learning. And it is rather hard at times to get him to buckle down and grasp what we are trying to teach him. He takes 15mg of Focalin for his ADHD to help him focus especially in school I was afraid go higher in dosage. As of the last 4 to 5 months he has been prescribed 0.1 mg of clonidine to help him sleep at night. After so long of resisting this drug I gave in because he really needed it. He would stay up all hours of night which is not good for a child getting up early to go to school and needing to focus. He would find every excuse to stay awake, have tantrums, cry etc. Since clonidine he goes to sleep within the hour he is given it. It was a God send. But I truly do not want him to be dependant on this drug. How addictive can this be? Can he ever go to sleep without it? One Friday I tried not to give it to him and he stayed up untill 2 or 3 am. I call it his night time vitamin. What scared me is the last two nights he is asking for it. "Mommy can I have my night time vitamin now". I also have made it a habit to give him his regular multi vitamin(gummy) right after the dose of clonidine So I don't know what he is really looking forward to. Is he becoming additive to clonidine or what? I look forward to your answers in e-mail thank you.

For those of you looking for help getting kids to sleep without 'drugs': Don't wait another day/night --> Try MELATONIN about 15-20 minutes before bedtime. It is natural and very effective at low dose. It is not habit forming. If your child can't/won't swallow pills - you can crush it (into a fine powder) and mix into a spoon of peanut butter (or whatever creamy treat they like) and it disappears. We called it his 'midnight snack'. When my son caught me putting it into the peanut butter...I said it is called "Magic Sleep Dust", because to me that is exactly what it was. For the first seven years of his life, it was like he only needed from 30 minutes to (if I was lucky) 2 hours of sleep a 'night', then he would be "good to go" for another 24 hours! I was living a nightmare and then one day I finally found a natural remedy: MELATONIN. Look into it and help your child (and yourself!) to some much needed rest. :) Best wishes to all, ~Mumzy

Has anyone experienced extreme skin irritation where this patch is placed (to be clear, not the outer covering patch, the actual clonidine patch)? My son has a red raised welt from it and the doctor said to keep using it with hydrocortisone cream. I am not happy with this answer... We are not using this med for sleep (he's a great sleeper) but to help our ADHD/learning-challenged son to be less aggressive and out of control when the Vyvanse (which works great but only for about 6-7 hours) has worn off.

My son is 14 he has had ADHD since he was in 2nd grade and taken propranolol for his head aches and vyvanse for his adhd which worked great but this past year he started showing signs of tic (movement and vocal) which is tourette syndrome and hurting him in school so the doctor changed his vyvanse to daytrana patches it worked ok with his ADHD and it did ok with his tourettes for 3 days then the tourettes came back so he tried (intuniv)a stimulate with daytrana still didn't work so the doctor took him off everything but propranolol (head ache med) and put him on clonindine 1 tablet 0.1 at bed time a lil over a month ago that was helping his tourettes amazingly but his it seems like it is making his ADHD a lot worse he use to listen before he got put on clonindine we taught our kids respect and to act right and obey adults and with all the other meds and no meds he will listen and obey adults and do wat he was told and not argue back ( no more than a normal teen) we went to the doc again a few weeks ago so he decided to put him on clonindine 0.1 3 times a day,strittera (a stimulate), and his propranolol (for head aches) and at first he was being good with tourettes and ADHD (i think mainly because he would come home do his home work and go to sleep we had yo wake him up for dinner and he would go back to sleep) but now his ADHD is even more worse than before very aggressive, argumential and just all the way around bad aditude and behavior. He never got in trouble at school until he started the clonindine I have told his doctor and he just up the dose. And it doesn't seen like he wants to change it or give him 2 diff meds one for his ADHD and one for his tourettes and i am at a loss. I'm going to call the doctor tomoro I was just wondering if anybody else has had this problem before or now... And before anybody says it is just because he is becoming a teen, its not I have a older son who is also ADHD and bi polar, and a younger sin who is also ADHD and has anger issues. But they listen and don't argue back (more than a teen and pre teen ADHD boys with emotional problems) but with him it has become a nightmare argues over everything, purposely does the opposite of what youu tell him to, very aggressive , and argumentive, pushes buttons, and will sit their and argue with youu and smile in your face. We have grounded him taking phone electronics away everything nothing works and I just know it is the clonindine has anybody else had this problem if so wat did the doctor do and did it help. He is making my other kids miserable and I love him to death and just want him to be happy and healthy but like I said the doctor doesn't seem to wanna try anything different I want to help him so bad but our home is like hell I dread when school gets out and he gets home because all it is is a battle with him now... So please help
