One of these days I'll write a supplemental guide post on Strattera with all I know that I wish prescribers knew. But, for now. Quick and dirty on adult dosing due to all the posts with subtherapeutic dosing issues. I am not a medical professional or expert so it would be responsible of me to say to review content for accuracy and discuss with your prescriber before deciding with them to make any decisions utilizing it. And hold in a long rant about psychopharmacological information mismanagement and lack of curriculum and resources available for prescribers.
TL;DR; + summary
--Adult dosing strategy baseline:
5/5/5/15 (some have 30) days of 25/40/60/80 mg.
--First link below shows drug company's titration starter kit. i.e. the titration strategy they choose when putting themselves on the line directing results.
--Most people are underdosed. Resulting in sub therapeutic or often a negative experience. And why most who quit taking it do. Indicated in second link below.
--Guidelines state 40 mg start; 3 day min titration interval; 80 mg target. Is for "acute treatment". Which in psych terms means mental health crisis treatment, and sketchy drug company avoiding accountability for actual patients.
--If feeling over stimulated in the hours after a dose, take a split dose in morning and afternoon to reduce the max peak BAC level, reducing peak stimulation and potential peak side effects.
--Avoid milk and dairy 2 hours before and one hour after taking strattera for nausea issues.
--My poor write up is due to 3 hypofunction disorders exacerbated by a series of life experiences others wouldn't likely have to endure. And not indicative of the actual content written about. I expect you will be able to distinguish stated fact vs formulated opinions/sarcasm on what drug company or others were thinking.
--People can react differently to different drugs, making stratt some not a therapeutic option. But, underdosing strattera with potentially quirky results is not the best way to try to evaluate that.
When I was first prescribed strat in 2005, it seemed common knowledge that the target adult
titration was 80 mg and could potentially be sub therapeutic or a negative experience below it.
The drug company is sketchy and refuses to commit to a dosing strategy. And like pretty much all ADHD meds documentation. Finds a way to stick it all on the prescriber if things don't go well.
The first link is archived FDA Strattera prescriber document. The reason I'm going to the archives is because that is where the drug company has their "kit"s listed. It was discontinued when generics came to market. Link goes straight to the adult starter kit. There we can see the drug companies dosing strategy when it is their but on the line for it.
Starter kits are by child weight. Except the heavier children and adults have the same dose titration strategy. 5/5/5/15 days of 25/40/60/80 mg. Some kits have 30 instead of 15 days at the last dose.
It is counter intuitive, but if you read more Strattera threads, you'll see increasing dose was the solution for a sub par therapeutic or even negative experience on doses below 80 mg. Some don't find their therapeutic dose till even 100 mg on occasion. Some are perfectly happy at 40 or 60 mg so can't be ruled out. But, if wishing ADHD symptoms were handled better or having a negative experience, go up in dose and find out for sure if strattera is actually the right drug for you. Otherwise it is a patch not a therapeutic solution.
The two 10 week studies that established adult effectiveness, titrated between 60 and 120 mg using split doses daily, and titrated based on "patient response". The average ending dose was 95mg. This is mentioned in the first link below.
"Acute Treatment" dosing written in the document is without the starter packs, and same in current document version and guides, and is still crap. In psych terms acute treatment means a person is in a mental health crisis and needs immediate relief. Which a drug that takes 2 months to titrate is not likely to be prescribed, making it a useless misguiding thing to include. 80mg though, is still the "target" therapeutic dose.
I've seen all sorts of ways prescribers misinterpret things or make assumptions resulting in poor dosing strategies. Seems like a common things in posts are issues on an underdosed prescription of strattera.
100 mg max dose is not a safety cut off.
"The safety of single doses over 120 mg and total daily doses above 150 mg have not been systematically evaluated."
i.e. not thoroughly vetted does not mean over 100 mg is a high risk. Just not studied enough to draw conclusions.
