They are both effective. You need to be carefully monitored by a doctor and not take any after 5pm.
Good luck. Be careful.

Both medications need to be prescribed by a physician. You can read about them, their effectiveness and all at

Amphetamine side effects:

” Constipation; diarrhea; difficulty sleeping; dizziness; dry mouth; headache; loss of appetite; nausea; nervousness; restlessness; stomach pain or upset; unpleasant taste; vomiting; weight loss.

Seek medical attention right away if any of these SEVERE side effects occur when using Amphetamine/Dextroamphetamine:

Severe allergic reactions (rash; hives; itching; difficulty breathing; tightness in the chest; swelling of the mouth, face, lips, or tongue); blurred vision; change in sexual ability or desire; chest pain; confusion; depression; fast or irregular heartbeat; fever; growth suppression; mental/mood changes; numbness or tingling in an arm or leg; one-sided weakness; painful or frequent urination; seizures; severe headache; severe stomach pain; severe weight loss; sudden severe dizziness, fainting, or vomiting; uncontrolled muscle movement; unusual weakness or tiredness; vision or speech changes.”

methylphenidate long acting…less addictive

I am pleased to have the opportunity today to share with you what we know about this complex multi-faceted problem.Ritalin, or methylphenidate, has much in common with cocaine the two drugs bind to similar sites in the brain and both increase dopamine through the same molecular targets.

I would say neither, drugs is drugs stay away from them.

Studies show hands down, that stimulants improve concentration (focus).
Those who really need them do not become addicted if taking the correct dose. When taking stimulants for good reason, if there is a speedy sensation, the dose needs to be dropped back. Because of an increased ability they naturally increase cognitive ability but only for a brief time.

It is ludicrous to believe that the drugs mentioned above cause all of the side effects listed. The truth is that the drugs could cause 1 or 2 side effects in a certain percentage of the population, which is really quite low. When examining side effects of a drug online, be sure to look at what percent of the population is affected by each side effect.

The good thing about stimulants, as opposed to antidepressants, is that their action occurs immediately, so if the user wants to stop taking the drug, its out of the system fairly rapidly.

In any case, the benefits of a drug have to be weighed out with the cost of not taking them. Asperin can cause stomach bleeding and ulcers in a relatively large percentage of the population. But if you were facing a second heart attack, it might be a good idea to take a baby asperin daily.
