Long term effects? | ADHD Information

Share
Is there anyone out there that has taken medication for adhd from childhood????? Ok if not: anyone know where I can reasearch the long term effects of these meds for adhd? Let me explain: we are 'not' wanting to medicate our son; but we may have no other alternative. I just wonder about the long term effects...any/all help on this subject would be most helpful for us. No, I was serious! I'm way to distracted to go to all those theres myself, and not really interested, anyway. As it seemed important to you, and I like knowledge, I figured we would both benefit if you did a little summary like.

Anyway, I guess it proves we're both AD, eh? hehe

PubMed would be the logical place to start:

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi

You could also try Google scholar (scholar.google.com). You likely won't have access to any of the full articles,  but the abstracts might be informative. Try searching on strings like 'long-term effects methylphenidate', etc.

If you want a summary in a nutshell, it's probably fair to say that most drugs used to treat ADHD have a very favorable profile in both the short and the long term. Methylphenidate (Ritalin) in particular, has been widely used for about 40 years with very few serious adverse events (e.g., heart attack) reported. (Keep in mind too that when millions of people take a particular drug, it's inevitable that some people will suffer nasty effects. For example, many people have died of aspirin-induced hemmorhages, yet no one calls aspirin a dangerous drug, because it's improved or saved far more lives).

There's even some emerging evidence that Ritalin may be good for children with ADHD. Recent studies have shown that ADHD kids who take stimulant medications are at lower risk of drug abuse and delinquent behavior in their teens and into early adulthood. There's also some very tentative work suggesting that methylphenidate may actually reduce risk of some cancers in the long term. That's probably not anything worth celebrating, since the reduction in animal and human studies is insignificant in the bigger scheme of things, but it does indicate at the very least that Ritalin certainly doesn't cause cancer. Overall, virtually every review I've seen of long-term Ritalin use suggests that there are no adverse effects.

The verdict on other (mostly newer) medications is still out (particularly Strattera). At high doses, some of the amphetamine compounds that make up Adderall have a neurotoxic effect in rats, but it's not clear whether it occurs at the lower doses typically prescribed for humans (probably not). Given the similarities between ritalin and adderall it's probably just as safe for the long-term. Still, since there are fewer studies out there, it might make sense to go with Ritalin if you have a choice (assuming both drugs are equally effective, which they may not be).

To sum up, there's very little evidence to suggest there's anything dangerous about treating ADHD long-term with medication. The bigger concern is over short-term side effects: many kids (and adults) simply can't tolerate the drugs, and so have to go off them. If you can live with the side effects without too much trouble, it's unlikely things are going to get worse in future. While you can always try alternative ADHD treatments, you should recognize that they're unlikely to work nearly as well (if at all). Given the low risk involved, I can't think of any good reason not to try medication as a first-line treatment (which isn't a reason not to do other things as well, of course, e.g., eat right).

Hi Nuncle

Where is this research about Ritalin reducing the risk of some cancers in the long term? Do you have a link to any of the research? I thought the most recent research showed that Ritalin caused an increase in chromosome abnormalities which is associated with an increased risk of cancer.

The long term effects of these meds is something I am anxious about and if I can see this tentative work about Ritalin potentially reducing risk of some cancers it would certainly make me more comfortable taking the meds.

Mike,

An animal study to this effect:
http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&a mp;db=PubMed&list_uids=8545847&dopt=Citation

The authors found that while MPH slightly increased the incidence of benign liver tumors, it decreased the incidence of several types of cancer. But keep in mind that the doses used here greatly exceed those commonly used in ADHD treatment.

Concerning the mutagenic effects of MPH you mention, those data haven't been replicated, as far as I know. There's a recent study here:

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&a mp;db=PubMed&list_uids=12742508&dopt=Citation

That found no genotoxic effects of MPH at much higher doses than those commonly  prescribed.

The only long-term study of cancer incidence in patients prescribed MPH is:

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve &db=pubmed&list_uids=2571410&dopt=Citation

In 539 long-term MPH users, the incidence of cancer was significantly lower than expected by chance.

I want to stress that these data shouldn't be taken too seriously: there is really very little research out there looking specifically at long-term carcinogenic effects of MPH (though what data exists is negative). And certainly, one shouldn't conclude it's a good thing to be on Ritalin or Adderall! The point is just that there's really no substantive evidence to suggest that there's a significant risk associated with taking MPH for the long-term at therapeutic doses.

I really don't know why you'd take the word of a website selling a product called 'Instant Learning' over hundreds of published peer-reviewed scientific articles spanning several decades. There's no question that stimulant medications work for ADHD. Do they work for everyone? No. Will the same medication work in all cases? No. But clearly it's foolish to disregard the mountains of evidence (not to mention the testimonials from any number of people on these boards) indicating that stimulant medications are highly effective in both the short and long-term, with a relatively minimal side effect profile. The issue in this thread is not whether medication is effective or not in the long term, it's whether it's safe or not. The former is a non-issue; the latter is still an open question, though to date the safety record of stimulants is very good.
[QUOTE=oldmember]I read at how to learn.com that these meds don't prove  any long term effectiveness.These kids struggle cause things just get harder as you go. [/QUOTE]I may be taking this way out of context, but I'm incapable of digging back to see where this thread started. ADD moment. But these meds aren't designed to produce long term effectiveness unless they are taken long term. Except for Strattera, their 1/2 life is measured in hours. The LA and CR stuff is extended b/c it's slow release of the active, not a prolonged active.

If things are not properly diagnosed, treated, and managed, things may get harder with time. If properly done, they get easier. Even without meds, adolescents and adults have learned survival coping mechanisms, that give the appearance of the disorder fading, but a genetic deficiency remains such, unless gene splicing is done. And we're not technologically there yet for humans.

It's my experience and contention that properly identified, treated with meds, coached, managed, trained and supervised, ADHDs have the potential to change the world again. Somewhere around here's a list of famous historical figures with ADHD, such as Lincoln, Edison, Da Vinci, Hornor, etc. Peter the Apostle and David the King were, also. God know what He's doing.

In good hands, an ADHD will change the world. I'm feeding 50% more people melons due to a pgr I helped develop. I save lives as a volunteer EMT. I open eyes, and rescue white rabbits stuck in their boxes...

It's up to the reader to evaluate. A link to an abstract on PubMed doesn't mean you can necessarily trust the data reported. That said, publication in virtually any peer-reviewed journal indexed by PubMed probably makes a study a better source of information than the proclamations of self-pronounced experts elsewhere on the web (including these boards

It is absolutely up to the reader to evaluate as when doing research, one must not only consider the content but also the source of information. Self proclaimed experts can also be found in the media and telelvision land as well. Perhaps what I should have said is that IMO, its a more reliable source of information and I certainly have never or would ever adivse anyone to beleive what they read to be accurate or true  as its all up to the individual to decide.

You must be kidding right? There's NO way I can give you 'any' summarization on this matter just yet...however the links are very informative I have been to them and bookmarked them so I can return when I actually have the time to really READ without being interrupted. I'll certainly give you my input once I've looked over all of the 'very' informative information. But one thing: I really thought that link http://www.ncbi.nlm.nih.gov was a bit complicated. I mean I actually had to 'sign up' to be able to do anything there and honestly for me to take the time to sign up for things is VERY rare indeed. Again: thanks for all of your input (which I again will add that it seems that it's WAY over my head). Thank so so so so very much for all this reasearch...now I shall have to do my part and of course read it. *wink* Thanks again. Hi I am Paul's mother,

Seeing as you've read alot on this subject, can you summarize for us your findings? Like in an Abstract? Would you mind including positive and negative study counts?

Thanks.

[QUOTE] Hi Nuncle.....the articles you cited are from a very accurate source of information.[/QUOTE]

Well, PubMed only indexes articles in biomedical journals. Saying it's an accurate source is kind of like saying a library is an accurate source. There are lots of good articles to be found, but also lots of bad ones. It's up to the reader to evaluate. A link to an abstract on PubMed doesn't mean you can necessarily trust the data reported. That said, publication in virtually any peer-reviewed journal indexed by PubMed probably makes a study a better source of information than the proclamations of self-pronounced experts elsewhere on the web (including these boards).
Hi Nuncle.....the articles you cited are from a very accurate source of information.
Thanks for sharing

Thanks Nuncle that information is very helpful.

I have been pretty concerned about long term effects of meds since I read the article about the mutagenice effects of MPH. The information you have provided certainly helps to ease my worry about taking meds long term. The possibility that Ritalin may decrease the risk of some cancers is very interesting.
