Burn Rate Explained

Intuniv, As With Any ADHD Medications: Watch the Burn Rate

Intuniv Posts:
This post is the fifth, with four others, documenting Intuniv Overview, Dosing Details, Drug Interactions and Addiction Indications. Please review all of these posts and the many comments [over 150] on the Overview post to see what readers are saying about Intuniv, this interesting new ADHD non-stimulant medication.

Burn Rate:
If you have been reading CorePsych Blog you will note that I have been writing about my new book, – and the good news, it’s finished, and in edit at this moment – I do hope to get it out by March ‘10. The Patient’s Guide for ADHD Medications: What To Do When Nothing Is Working details an entire chapter on Burn Rate, as everyone who takes ADHD meds should absolutely master the burn rate principle.

This Specific Q & A:
- Is an example of the many Intuniv questions, challenges and positive remarks in these several posts:

Question About 8 yo Boy, Picky Eater and Metabolic Challenges:
“I have just stumbled across you and this site in my research into Intuniv. My son just recently turned 8 and was diagnosed with ADHD this past spring. As I continually read about ADHD kids Luke seems wise beyond his years, is very bright when it comes to building things, or math, and picks things up quickly when he is receiving instruction one on one or in a very small group,- but he struggles in school generally. Long story short, we started with a Central Auditory Processing Disorder diagnosis when he was six.  His primary issue seemed to be language, both receptive and expressive. An exam with an audiologist confirmed a fairly significant CAPD at the time. As he progressed in school it was obvious that ADHD was also a large part of his problems as impulsivity, restlessness, inability to attend, and defiance increased as he got older. We saw a neurologist who, after an EEG, prescribed Focalin XR. This worked like MAGIC, at first.

We started with 5mg and after about a month moved up to 10mg. He was able to focus, concentrate and made great strides in school. His language issues even seemed to improve. Now it seems the Focalin is either failing him or is the wrong drug. His ability to focus has tanked, he has become very impulsive (throwing things, slamming things on his desk) and is increasingly defiant (refuses to do work, follow directions). While other times he seems spaced out, and at home sometimes too compliant, and sometimes melancholy for no reason. With age it seems his receptive language abilities are about right, and at developmental level, but his expressive abilities are still below, which of course is leading to some frustration on his part especially when he is supposed to expressing himself through writing. We were seen by the NP in the neurologist’s office today and she suggested Intuniv. From what I’m reading it sounds like it may work for Luke but she has suggested we stay on the Focalin while we start the Intuniv? Do you agree? (She mentioned d/c’ing the Focalin eventually)

Second, in one of the posts above you mentioned something about “immune dysfunction, bowel challenges and is-he-a-picky-eater”. While Luke is rarely sick, I don’t think he has a solid BM in his life (not watery, but always very, very soft) and he would live on Mac and cheese, peanut butter and jelly and chips if I’d let him. He NEVER willingly tries anything new and is indeed very picky about what he eats. As all of this is very new to me can you shed some light on what this may have to do with anything and what to do about it – or point me to the best place to read about it? We have tried adjusting his diet, etc. in the past but because he is so picky it is very difficult to do.

An Additional Metabolic Point - Headaches
One additional thing that the NP this a.m. more or less ignored – prior to starting meds Luke would wake up in the middle of the night crying and saying his head hurt. He’d be up 30 min. or more, would eventually throw up and then go back to sleep. In the morning you’d never know anything happened. This would happen about once a month from the time he was about 6. I only recall it happening once during the day at school. Once we started Focalin those incidents ceased completely. We had our first return of that 2 nights ago. Any idea what that’s all about? Initially the neurologist said it was “interesting”but had little else to say about it.”

My Answer, Abbreviated To Stay With Metabolism and Burn Rate:
My reaction to this question and many others seen on the many comments on Intuniv and Vyvanse: We must always look at the metabolic hints, the possible changes in metabolic rate before starting the meds. They are subtle but include the following:
- History of bowel issues, too soft, too hard, constipation, diarrhea, monolithic stools, too slow in transit time,
- Developmental delay issues: CAPD, speech issues, Asperger’s, Autism,
- History of Fetal Alcohol exposure
- Headaches, stomach aches, tired all of the time, dark circles under the eyes, pale skin
- Picky Eater
- Not eating breakfast, waking with stomach issues and no appetite
- History of failure with many meds – including stimulants or non-stimulants [Intuniv, Strattera]
- Narrow Therapeutic Window
- History of food allergies even back to early childhood, e.g. “lactose intolerance”
- History of rashes, allergies, asthma, upper respiratory infections, ear infections

If we don’t look at these issues [and more] we cannot predict what the outcome with the medications will be – and every one of these issues can significantly change the underlying metabolic patterns, the amount of neurotransmitters in the body, and the cofactors that burn the neurotransmitters effectively.

Medication management now requires a full awareness of the entire pattern including nutrition [which feeds the amino acid building blocks for neurotransmitters and cofactors], – without more careful questioning at the outset we will have predictable problems – as the burn rate will vary dramatically with all of these variables. Burn rate will effect Duration of Effectiveness [DOE] – dosage patterns and speed of titration at the onset of meds.

Then, if Burn Rate varies, we must always take the next step to measure the immune dysregulations, the neurotransmitters, and the downstream endocrine issues so often found with these upstream irregularities.

Intuniv for ADHD: Avoid Drug Interactions

Intuniv Driving And Watching: Possible Interactions Detailed

Wrong Med Turns

Wrong Med Turns

Regular CorePsych Blog readers already know that we don’t like wrong medication turns. Intuniv dosing is important. Intuniv safety has been carefully explored. Maps do help, but watching where we are going is even better. Consider this recent comment from a mother worried about Intuniv and Prozac:

Interaction Question:
Mom asks: It is such a relief to find some information from other parents and doctors who are trying Intuniv as it is such a new medication. My daughter has been taking it for about 6 weeks now. We went very slow on dosing just as you have recommended, and it is working wonders. I will say that she has become more irritable and extremely sleepy. I believe that as she adjusts to the dosage that the irritability goes away. However, we have just increased her dosage to 3mg, so she is still adjusting to the extreme sleepiness.

The doctor we are seeing put her on Prozac for anxiety, but have I read correctly that you would not recommend Prozac with Intuniv? She has been experiencing very strange sleeping patterns. She is either staying awake many hours, going to sleep right away and then waking hours early, or so sleepy she falls asleep around 6PM and sleeps through the night. Considering her sleepiness, the doctor recommended giving her the Intuniv at night and the Prozac in the morning, but this has not been helping. Should we be giving her the Intuniv in the morning despite her sleepiness? Also, would you recommend something other than Prozac for her anxiety.

My Reply:
Thanks for your kind remarks, and, yes, you read it right: Prozac and Paxil [and Luvox] should not be given with Intuniv, they inhibit appropriate metabolism, – interfere with Intuniv being processed by the body correctly. – And do skip the idea, suggested by some, that you should ’simply use less Intuniv and do use Prozac’ – the drug interaction experts entirely disagree with that incorrect strategy. Good guess, bad idea. :-?

Intuniv is a 3A4 substrate, but is not listed on the Prozac and Paxil link just above [is listed as such in the Intuniv PI [package insert]. You will see on this first linked list that they left out guanfacine as a 3A4 substrate, but they did cover the bases with the rest of the inhibitors I just listed. Also, on the induction [making it burn too fast and disappear] side, have to watch Tegretol or Trileptal, as they can both induce Intuniv [cause it to run through to fast requiring higher doses [see the first link], and for those treating bipolar disorder with Intuniv watch for Depakote as a inhibitor as well.

Your girl is very likely accumulating Intuniv by the blockage with Prozac, and is coming out the ‘Top of the Therapeutic Window‘ – with the result that your doc is doing what he/she knows best, changing the dosage time of day to accommodate to the obvious side effect. – Great idea if that basic drug interaction wasn’t the key problem.

In this case I strongly recommend you download and print the above interaction link for your doc, and get off that Prozac. What I find so disconcerting in this interaction scenario: Intuniv gets blamed for this weird reaction, and Prozac [and others noted] are the culprits. I have repeatedly seen this kind of problem with AMP products such as Vyvanse and Adderall for years, as many continue along in denial that the CYP 450 system doesn’t require attention – and the fact that dirty drugs can create significant problems with otherwise clean medications that work very well, if used correctly.

The good meds often get blamed as they are new, and the old dirty ones get off, based simply on familiarity! Sounds like a popularity contest, not science. – Not good form in the context of evolving science – and not implying your doc has any of these attitudes – just reporting they are clearly out there. Please talk to your doc about all these matters.

Drugs that are clean on both 2D6 and 3A4 are Effexor, Pristiq, Lexapro, Celexa, – and Lexapro [see the list] has recently found an FDA approval down to 12 yo. Irritability and sleepiness should go away – but, without knowing more, I would try her just on Intuniv alone before running another med in there, it might work well as a stand alone.
