Clonidine is trash for pretty much every indication, psychiatric and medical.
Thanks for this. Heard that Guanfacine is coming to UK in the near future. So we will be doing some experimenting as well. I know Clonidine has been used for trauma+ADHD. Personally I have not tried that. Here they go for atomox
I think you may be thinking about Prazosin for PTSD. You don't have guanfacine in UK? It's an old alpha agonist used for blood pressure that has been generic for years. You may be thinking about the extended release form called Intuniv in the US. Also, we have extended release Clonidine (Kapvay). We also have clonidine patches that can be used for 5 days. I don't like patches on kids as they can usually pull them off.
Prazosin seems to be somewhat of a regional thing and definitely a VA thing. I've seen clonidine used for PTSD hyper-arousal symptoms and for PTSD related nightmares. I'm more comfortable using prazosin, but I wouldn't be surprised if the poster above really did mean clonidine.

I think prazosin is more of a VA thing because there's more evidence for it than clonidine. I've used both for this purpose, but I like prazosin better because it has a longer half-life and more flexible dosing (you can relieve nightmares with 1-2mg, which doesn't drop the blood pressure as much as 0.1mg of clonidine).
Interesting commentary. I have definitely used clonidine for ADHD and definitely seen it be beneficial. I particularly use it in kids who have had in utero substance exposure to alcohol or methamphetamine who simply haven't tolerated stimulants at even micro-dosages because they send them into aggressive rages or make them irritable and intolerable. I have several handfuls of kids who have done quite well on clonidine as monotherapy for ADHD (e.g., young children, children with in utero substance exposure), but I tend to use it adjunctively. That said, I typically use Tenex over clonidine because it is less sedating, but in a kid with insomnia who hasn't benefitted from melatonin, I might go with clonidine first.
I also tend to use alpha agonists in very young children with ADHD when they're not going to tolerate a stimulant--say 3 and 4-year olds who are so hyperactive that they are exhibiting language delay and can't work with a speech therapist because they're bouncing off the walls like a ping pong ball. 0.25mg of Tenex can be your friend, and it can be quite effective. Give them even a milligram of methylphenidate, and you run the risk of seeing dilated pupils, hyperactivity and aggression. Clonidine and Tenex are also helpful for tics, whereas stimulants can be the exact opposite.
If you look at meta-analyses, clonidine actually has a decent effect size of 0.58 in the treatment of ADHD.

Prazosin is extremely effective for nightmares, and I found that working in a trauma-focused residential treatment center that I rarely came across an adolescent where I couldn't get them sleeping and get rid of their nightmares with it in short-order. I have seen Tenex and clonidine both be effective for hyperarrousal during the day for adolescents with PTSD, but I don't tend to use prazosin for this given its limited half-life.
Just one man's experience as a child psych. I like the alpha agonists and use them regularly.
How do you know that the micro dosages of stimulants are causing this worsening of aggression in the kids, rather than it being hyperactivity that simply needs a higher dose of stimulant before you see an effect?
Yeah, but there are also other prazosin studies. There's a review article somewhere in the universe looking at both clonidine and prazosin for PTSD. The authors said that they like both in their anecdotal experience, but it was pretty clear that the evidence was much better for prazosin, so I've been using prazosin exclusively for that purpose (unless I have a specific reason to use clonidine, such as comorbid ADHD with impulse control problems) ever since I read that.Yeah, weren't the main prazosin studies VA studies? Anecdotally I've had mixed results with prazosin, and I think I've probably prescribed it to almost all my PTSD patients. It's hard to get the dosage to the right amount, and I'm probably not as aggressive with that as I should be.
Several ways. 1) A consistent report from parents that the kid gets aggressive 20-30 minutes after administration of the stimulant that lasts for 2-4 hours, at which points the kid returns to baseline. Most parents won't wait more than 2-4 days like this before they're calling you. I do make them repeat the experiment once or twice if they're calling after one administration, as you may have caught the kid on a bad day. 2) You may also see is a kid whose irritability (maybe not having rages) gets better once you take him off of a stimulant. The opposite should be occurring. 3) I typically prescribe at least two dosages of stimulants when I first prescribe. One dose slightly lower than what I think they need (or a starter dose) and one higher dosage. Sometimes the kid does best when you underdose but gets cranky on the higher dosage. You lower the dose, and they get better.
A number of kids who see me have first seen a PCP who has started them on what I might consider an overly aggressive dosing of a stimulant. They get super cranky, and I might try a lower dosage if I think the dosage seemed high, which sometimes does the trick or other times simply induces the same irritability. Or sometimes I make them irritable by overshooting. I can think of a few kids where methylphenidate IR 2.5mg was too much, but where 1mg seemed to work quite well, at least until they grew some. Yes, that's well below manufacturer suggested dosing, and you're likely going to need to be using a liquid formulation.

I've had pretty great results with prazosin, but you have to push the dose sometimes. I feel like psychiatrists are often reluctant to prescribe more than 1-2 mg, but there's evidence for doses as high as 15 mg for PTSD. I usually start with 2 mg unless the patient's blood pressure is low at baseline, and I've never gone above 5 mg. I usually use it primarily while I'm waiting for an SSRI to kick in, but sometimes I add it on for somebody who has persistent nightmares despite an SSRI. I don't think you can consider it to be a therapeutic failure until you've pushed the dose.
I agree. In my experience, most people are not nearly aggressive enough with Prazosin. Didn't a large VA study (sorry I don't have the source) show that average affective doses of Prazosin for men with nightmares due to PTSD was around 9mg? I've seen dosage as high as 15mg. In my experience I titrate up until either the nightmares go away or the patient experience side effects (due to low BP) and can't tolerate higher doses.
Yeah, that's what I do too, although maybe I should push doses higher if the mean effective dose was found to be 9 mg.Agreed. Far too tame.
Clinically, the way I'm titrating it is getting a baseline of how many nights per week are they having nightmares working towards 2-3x/month. I don't want to push it beyond that because of the side effect profile and they ought to be working in therapy at the same time.
Titrate to effect.... Research is nice to let us know the mean dosage is this, but the individual may vary. I've had success at 2-3mg. The power is in the psychotherapy.Yeah, that's what I do too, although maybe I should push doses higher if the mean effective dose was found to be 9 mg.

Just wanted to add that abolishing the nightmares, although it is what most patients would want initially, might not always be the best thing. I find that the nightmares can be helpful as a guide and progress indicator for patients with trauma. I have some patients who have them every night, now if we could cut those back to the occasional, then that would be a different story. I have a patient with constant nightmares who was prescribed 4mg prazosin HS with no effect so the nurse practitioner d\c ed it. Might have to have a chat with her about potentially increasing the dosage. Also wondering if you think that severity of trauma or intensity or frequency of nightmares is correlated with effective dose?I saw a patient today who had significant improvement in nightmares on prazosin 2mg qHS. Last week, I might have kept her on that dose and called it a therapeutic success. After this thread, I talked to her about risks/benefits of pushing the dose to 4mg, and we decided to go higher in an effort to abolish her nightmares (SBP was 135, so she can tolerate it). Just thought I'd point out that this discussion helped make me a slightly better doctor. Although I guess it's hard to say whether that's true until I see her again and see if it actually worked...

We are also dealing with chronic pain and through psychotherapy, chiropractor, and pain management medications are making some progress there. It is all interrelated. The pain is exacerbated by the psychological distress and was caused by excessive working to avoid/cope with the PTSD symptoms. I don't know about sleep apnea, but this is the type of patient who tends to have it all so we might have to look at that down the road.Yes, and it depends on neurochemistry (which we don't have a test for) to look at how titration is going. For example, I just saw a 66 yr old with significant PTSD from a terrible car wreck where a family member died. She was doing relatively well at 8mg but with an increase in stressors at home, this kicked in worsening of insomnia symptoms from excessive thought rumination and had a cascading effect upon sleep with worsening of dreams and nightmares. I increased Prazosin to 10mg. Just remember, it won't take the dreaming away, it will change the character and quality so that it is less intense and with the improved sleep, can work better in psychotherapy.
Additionally, be sure to screen for other sleep disruptive disorders which could be the cause & effect for the nightmares, and treating the underlying cause along with accurate medication management will result in a much better therapeutic process. It really does end up being a team game in treating PTSD.

Gawd no--someone would have to write Goals and Objectives, we'd all have to sign disclosures....We should start getting CME credits for reading SDN. 🙂

Thanks for the info, I hadn't heard of CSA and also didn't really know about the sleep apnea/pain connection although I am aware of the depression/pain/opiate interaction and educate my patients about it. I wonder if our pain management person knows about it. I might talk about it with my patient today depending on the session, if not I'll have the pain management person address it with patient and make the referral. Fortunately this patient doesn't have a lot of axis 2 symptomatology which is almost surprising since she has everything else.OSA is linked to worsening of chronic pain syndromes. And plenty of research to show the correlation of worsening of mood symptoms with worsening of depression and anxiety symptoms - in some cases, it's not a direct cause and effect, rather the experience one has with pain and how they cope with the symptoms.
http://www.ncbi.nlm.nih.gov/pubmed/?term=osa+and+chronic+pain -- this was quickly searched between patients. You get the idea.
Additionally, pain medications can create a different kind of sleep apnea called Central Sleep Apnea. The effect is still the same as it is a sleep breathing disorder which interrupts sleep, thus contributing to worsening of mood, anxiety and pain symptoms potentially. Again, it's not a 100% correlation but looking at it from a holistic management POV, it does get pretty complicated and a lot of education needs to be provided. Most of the time people are receptive to the information, those with significant personality disorders are the ones who'll buck back hard and would likely benefit from DBT initially to reduce the extreme catastrophic thinking.
