Long Term Effects of Adderall

Admin — Fri, 08 Jan 2010 11:10:20 +0000

Adderall is a popular stimulant treatment for ADHD and is used illicitly as a drug for its energy inducing effects.

What are the long term effects of Adderall? Does it keep working, or do you develop tolerance if you have ADHD?

Please note that this piece is written assuming use is within therapeutic range for ADHD and not at the high doses typical with abuse.

Summary of long term effects of Adderall

Mental: Increased focus, attention, motivation. Reduction of ADHD symptoms.

Heart: Use of Adderall or related stimulants for more than a year increases your diastolic blood pressure by ~ 3-5mm HG, systolic blood pressure by ~ 2-5mm HG and your heart rate ~ 3-5 beats per minute. Additionally, it is possible that ECG testing will show slight electrical activity differences.

This is almost always not good (except possible in someone with initial low blood pressure), but is it bad? Some argue that these increases don’t have any direct health implications, while others argue that they can show a 20% increase in emergency room use for heart issues in kids who use stimulants.

Before using stimulants, it may make sense to get some basic cardiac testing.

Brain: Some studies have shown that stimulant use in people with ADHD may increase the size of certain parts related to controlling focus, motivation and attention. This is very positive. Some studies we’ve looked at of students on long term use of stimulants showed improvement in overall academic performance as well.

On the other hand, some animal models have hinted at the possibility that use of stimulants can increase the build up of free radicals in the brain. Even if this is the case, it might be amenable by healthy consumption of anti-oxidants.

Appeptite/weight: Amphetamines like Adderall are among the best appetite suppressers. This led to their wide abuse as diet pills and may cause unwanted weight reduction in people who use them. Long term use in kids has been shown to be associated with slight weight loss and even possibly slight height reduction.

ADHD Treatment Effect: Many people taking stimulants ask the question – will they stop working? The news seems to be good, however.

Researcher Doctor Biederman reports that in a study of several hundred patients over 1-2 years, for most, stimulant medications continued to work well at a steady dose.

Doctor Hallowell, coauther of Driven to Distraction, reports that in almost all cases, tolerance to ADHD medication does not develop, but is possible. Dr. Paul Wender, a noted researcher into ADHD, reports that tolerance is rare, and most patients can take stimulants for many years without problem.

Dr. Ari Tuckman, a clinician who has treated hundreds if not thousands of people with ADHD, reports in an interview with us that most often, ADHD meds can be used at therapeutic dose daily for years without losing efficacy.

Of the dozens of research papers reviewed, very few mentioned that developing long term tolerance was a limiting factor in treating ADHD. Even then, it is almost always the case that tolerance can be reduced or removed by temporarily stopping treatment.

That said, there could be more research and data on this subject.

What does that mean?

With the increasing use of amphetamines to treat ADHD and as recreational drugs, more and more people want to know – are they safe for long term use? What potential side effects come with use over time? And, this is exceptionally important, do they continue to treat ADHD over time or does drug tolerance develop?

There have not been that many studies into the long term effects of Adderall. One thing we know is that stimulants do have some cardiovascular effects which can be serious for at risk people. That said, one study of several hundred people over 2 years of mixed amphetamine salt treatment (the generic for Adderall), showed no clinically relevant heart effects – at least according to the doctors and researchers who did the trial. A few people did drop out because of heart related concerns like palpitations and excessive heart rate.

Additionally, a retrospective analysis of about 2,000,000 kids treated over time with stimulant medications showed that 456 went to the emergency room with heart related issues. When you control for how many kids would normally go to the ER in a sample that large, this represents a 20% increase in risk for heart problems.

Remember, there is a black box warning on stimulants because of their potential for heart complications.

In terms of developing tolerance to the therapeutic effect in treating ADD/ADHD: the data seems to very strongly suggest that tolerance does not develop over a year or two year period, and that use of extended release formulations may increase efficacy due to smoother release.

Attenuation of side effects?

It is possible that with time, the side effects of stimulants become attenuated, or less significant. For instance, one study showed that a significant amount of people experienced insomnia, depression or weight loss at start of use of stimulant medication.

But near the end of a year, only 1% still had a reduction in appetite that would lead to weight loss, and no one reported insomnia (which sounds a little over-optimistic. Everyone has insomnia sometimes.) This may be, however, because those who had serious difficulty with those issues stopped using the medication.

Adderall vs Ritalin – Benefits, Problems

Adderall vs Ritalin:

By the time you’re done reading this article, you will know how Adderall and Ritalin compare. Is one better than the other?

If you want to know what Ritalin actually is and how it works, see here.

And are you confused by all your medication options? (Ritalin, Adderall, Focalin, Vyvanse, Intuniv, Metadate, Pemoline – and that’s just getting started!) Figure things out – a Full List of ADHD Medications tells you what you need to know.

The Chemical difference

Ritalin goes to brain cells and stops them from taking up dopamine and norepinephrine, which are chemicals associated with focus, motivation and pleasure. That increases the amount of them in the general space between cells.

Adderall does the exact same thing. It also, however, goes inside cells and makes them pump out dopamine. It not only blocks the reuptake of the substance but also acts to increase its levels directly.

It is this mechanism that may explain its slightly higher strength in some ways.

More about Ritalin

Ritalin is the most commonly prescribed stimulant for ADHD, far outselling Adderall, but this doesn’t mean it’s better. It’s just been out a lot longer. Ritalin and ADHD are pretty much synonyms, and that association makes a big difference in doctors’ prescribing habits.

Chemically, Ritalin is derived from an amphetamine and has very similar biochemical behavior.

It is a very effective treatment for ADHD. Roughly 55% of those who use Ritalin experience benefit. Combined with therapy, however, that number goes up to 70% or even 80%.

The reason for this difference is likely that Ritalin, at the right dose, enables you to perform in a less “ADHD” style, but you still have to learn how to do so.

You can get Ritalin in an instant release (IR) and extended release (XR) form. On the one hand, extended release means more consistency and more convenience. On the other hand, instant release might provide more of a “punch” so to speak.

Clinicians we’ve spoken to tend to highly prefer the extended release form as it is less variable and makes life a lot easier than instant release.

More on Adderall

Adderall is a mix of amphetamine salts, and it works about as well as Ritalin. It too is available in IR and XR form. It’s become increasingly popular since its introduction in the 90s. And it might just be a little stronger than Ritalin.

Some studies show that kids need to take 2 instant release pills of Ritalin to cover a day at school, while 1 IR of Adderall works similarly well. It is possible that an instant release of Adderall works for 5-6 hours, although officially, it is supposed to work 3-4 hours. Molecule for molecule Adderall is more potent. But that might just mean you take less of it than Ritalin.

Some other studies show that Adderall produces a slight advantage over Ritalin in treating certain symptoms. One study showed that Adderall had significant advantage in keeping people on task and helping stay focused. But please take that study in context. It wasn’t a rigorous clinical trial, and only examined 37 patients.

Larger, more scientific studies have also shown a slight advantage of Adderall over Ritalin. The difference is so small that in any one given study it might not mean anything. What makes it significant is that the slight advantage of Adderall seems to occur in multiple studies.

More interesting is that people who start Adderall might be more likely to keep on using it than Ritalin.

And in a summer school study at SUNY Buffalo, Adderall was viewed to be slightly more effective. Staff clinicians especially liked it, favoring it 3 to 1 over Ritalin, but of course they weren’t the ones taking it.

Efficacy:

Dr. Tuckman, a clinician who has treated hundreds, if not thousands, of adults with ADHD has this to say: Roughly 1/3 of people with ADHD respond best to a Ritalin type medication, 1/3 to an amphetamine type such as Adderall and Vyvanse, and 1/3 respond equally well to both.

So Adderall and Ritalin are about as effective for treating ADHD, and some people respond better to one or the other.

Side Effects:

Adderall may be slightly stronger than Ritalin. It may also have slightly different side effects. One clinician’s study showed that Adderall was less likely to cause anxiety and agitation, while being more likely to cause insomnia.

Adult ADHD:

ADHD can be a lot different in adults than in children. If you are concerned that you have ADHD and are over 18, see an ADHD Test Made for Adults.

Is Stimulant Treatment for ADHD Safe?

Admin — Wed, 05 Aug 2009 01:16:11 +0000

ADHD is most often treated by stimulants like Ritalin, Adderall, and Dexedrine. I’m sure you’ve heard of these medications – but what are they? What do they do?

And most importantly – are they safe?

Are Stimulants Safe?

Stimulants are powerful medications, potentially addictive, and can have very serious side effects.

They’re commonly used because they’re effective. Up to 70% of people experience significant symptom relief on them. And the majority of the millions of people who use them are fine. But they do have common side effects, and can rarely cause some quite nasty things.

The most common issues with stimulant use include increased anxiety, nausea or loss of appetite, and insomnia.

The rarer and very serious side effects? To quote an ad for Vyvanse, an ADHD medication, “new psychosis, mania, aggression, growth suppression and visual disturbances” are possible.

Heart Damage?

Stimulant use might cause heart damage over time. Stimulants typically increase heart rate by ~3-5 beats per minute and also raise blood pressure. One study of more than 50,000 children using stimulants showed an 20% increase in risk of emergency treatment for heart problems.

Use of stimulants by someone with a preexisting heart condition is a big no-no, as they may increase risk of cardiac failure or sudden death.

Psychological problems

As mentioned, a rare but serious side effect is that stimulants can cause psychosis, or a break with reality such as paranoia, delusional thinking and hallucinations. Most psychosis occurs in people who were already at risk – but stimulants can cause psychosis in normal people at normal doses.

Stimulants can also cause serious problems with regulating or controlling mood. They can trigger mania in bipolar patients, and cause extreme mood variation even in people not normally at risk for bipolar.

Stimulants change the brain

Do stimulants cause brain damage? Maybe.

Studies in rats have shown that extremely high doses of amphetamines given over a short period of time cause serious damage to the production of dopamine and its transport in the brain. This happens by causing build up of radicals and reactive oxygen species. Methylphenidate, or Ritalin, does not cause this damage, possibly because it only blocks the receptors for reception of dopamine.

But what about normal use?

The rats did not experience neural changes or damage from doses in the normal range. The news isn’t all good, though. Baboons and monkeys, however, did experience brain damage at normal doses, showing a significant reduction in natural production and handling of dopamine.

It’s not clear what this means. Children who take ADHD medication, after all, have larger white brain matter than unmedicated children, indicating a neuro-positive effect.

Remember: use of stimulants in children requires extreme caution and psychological analysis because they are young, more susceptible to side effects, and still developing.

Do stimulants like Adderall and Ritalin stunt growth?

This question is extremely contentious. A number of studies have shown that stimulant use is associated with slightly reduced growth, and, on the other hand, a number have shown that they aren’t.

The evidence, in my opinion, seems to be in favor of a slight reduction in height associated with long term use.

Both sides agree that stimulant use initially slows growth somewhat; the question is if that delay is made up for in the long run.

Stimulant use is, however, associated with some degree of weight loss in the long run.

Conclusion:

Stimulants are extremely commonly used for a reason. They work. That said, they are potent substances, and often require supportive psychological therapy on the side to achieve best results.

For someone with a history of anxiety or other psychological problems, or someone with cardiac issues, use of stimulants should be exceptionally cautious if at all. Use in children should also be done with extreme caution and only after appropriate psychological evaluation.

Vyvanse vs Adderall XR – Benefits, Problems

Admin — Mon, 06 Jul 2009 15:48:33 +0000

Vyvanse vs Adderall XR:

Vyvanse is a new treatment for ADHD and this article compares it to Adderall.

If you want to learn the 10 most important things you should know about Vyvanse, see here.

Are you confused by all your medication options? (Ritalin, Adderall, Focalin, Vyvanse, Intuniv, Metadate, Pemoline – and that’s just getting started!) Figure things out – a Full List of ADHD Medications tells you what you need to know.

Now…

First, it’s important to realize that Vyvanse is Shire’s replacement for their old blockbuster drug, Adderall XR, which is losing its patent.

If you’re being suggested to take Vyvanse, it’s not necessarily because it’s a better medication.

Shire wants to turn it into a billion dollar drug, and has unleashed a marketing campaign of that magnitude, aimed at consumers and doctors.

On the other hand, Vyvanse does have some advantages over Adderall. It also has a few disadvantages.

Comparing Vyvanse vs Adderall is made slightly harder because both drugs are amphetamines. If you take either, you’re getting pretty much the same thing.

That said, there are some important differences.

1) Vyvanse is 100% d-amphetamine, while Adderall XR is a mix of 4 different d and l-amphetamines.

This mix in Adderall may make it more effective, stronger. But it might cause more anxiety or physical side effects. See later for discussion of the differences between the amphetamine types.

The next big difference is that:

2) Vyvanse is released via digestion, while Adderall is released by bead technology.

The digestion release may make Vyvanse smoother, last longer, and have less variability. What you eat might not effect it so much, while Adderall XR may be more effected by, say, having a cup of orange juice.

This release also means that snorting or injecting Vyvanse provides less of a high. As many have pointed out, however, Vyvanse can provide a high just by being taken at higher doses.

Advantages of Vyvanse

We have a full article discussing the Advantages of Vyvanse.

Vyvanse has been shown to have effect for a very long time, up to 14 hours in some studies. While realistically that duration of effect may not happen, it works fairly well for fairly long.

This is likely because its release mechanism is typically smooth, meaning less variability.

Finally, Vyvanse is pure d-amphetamine, which may mean less of certain side effects compared to the l and d-amphetamine of Adderall.

Disadvantages of Vyvanse

Vyvanse is basically nothing more than extended release Dexedrine. And while it seems to have fewer side effects relating to anxiety and release, it may cause more side effects like reduced appetite.

Because Vyvanse is so new, it may be significantly more expensive than other options or not covered by insurance, especially since both Dexedrine and Adderall are available in generic form. We also simply do not know as much about it as we do about the older drugs.

Finally, some users feel that it’s not as strong as Adderall, and that it stops working earlier than advertised.

l versus d amphetamine

Remember that Vyvanse is pure d-amphetamine, while Adderall is a mix of d- and l-forms.

The d form may be more effective at reducing impulsiveness and overactivity. The l form, on the other hand, may increase concentration better, but it may also cause more anxiety. It is also per molecule less effective than the d form, but such a distinction is perhaps irrelevant.

The d form may effect more dopamine, as opposed to both noradrenaline and dopamine in the l form. This theory, however, is not established. Noradrenaline is involved in anxiety responses, which may explain why Adderall XR seems to be worse for anxiety.

Adult ADHD:

ADHD is a lot different in adults than in children. Hyperactivity, for instance, is not necessarily there or in the same form as in kids.
