Concerta: instructions for use

Generic Concerta is an adrenomimetic of central action. A medication that increases the rate of metabolism in the brain. The active ingredient of the drug is methylphenidate hydrochloride - known as a central nervous system stimulant. This drug is prescribed for hyperactivity and attention deficit syndrome.

The mechanism of action is to reverse the capture of dopamine and noradrenaline by presynaptic cleft neurons and inhibits the release of monoamine neurotransmitters into the extraneuronal space.

Concerta is a well-known medication for the treatment of hyperactivity and attention deficit disorder

Official statistics state that hyperactivity and attention deficit disorder suffer about 3-5 percent of people. This disease is inborn and associated with a genetic predisposition of the brain, namely the dopamine system, which is responsible for pleasure and motivation in learning. When a person experiences positive emotions, dopamine is released in large quantities, and with Attention Deficit Disorder, a person is prone to depression, which interferes with feelings of joy and interaction with the environment.

Most countries use Concerta as a psychostimulant. ADHD is not curable with this drug, but it can compensate for many biochemical processes in the patient's body and bring them back to normal.

Active ingredient

Methylphenidate hydrochloride


Concerta and Adderall are very effective in the treatment of ADHD. Which drug is best for you depends on the individual characteristics of your body. Do not prescribe the drug yourself, only a doctor can assess all the risks and prescribe the method of treatment that is suitable for you.

Concerta vs Ritalin

When comparing Concerta and Ritalin, remember that both drugs contain methylphenidate, so they are essentially the same drug. The only difference is in the way the medication is dosed and how long it lasts. Concerta works for about 12 hours and is dosed once a day in the morning, so this medication may be a better choice for those who are busy during the day and do not want to take extra doses of medication. Ritalin lasts about four hours and requires taking the drug several times a day.

Which is the most effective medication for you will be determined by your doctor, who can take into account your condition, as well as your medical history and other medications you are taking and their interaction with Concerta or Ritalin. Ask your doctor for medical advice.

How long does Concerta last?

The therapeutic effect of Concerta lasts about 12 hours after you take it once a day in the morning.

Concerta: weight loss

The effectiveness of Concerta (Methamphetamine) weight loss is due to its chemical structure similar to that of human adrenaline.

Methamphetamine promotes weight loss because it has the property of stimulating lipolysis. Consequently, the volume of fat cells decreases significantly. The person has a decreased appetite and physical hyperactivity is present. Energy is lost in a huge amount. In other words, the body's reserves are depleted promptly. However, Concerta is rarely prescribed as a drug for weight loss because the drug has many side effects.

How long does Concerta stay in your system?

After the dose is fully metabolized, it is excreted through the excretory system in the form of urine.

The time it takes to excrete the drug varies from person to person. Some patients excrete the entire dose in just one or two days, while others may excrete only 75% of the same dose in the same amount of time, so it all depends on the individual's physical data. Urine tests may show the presence of Concerta within one to three days of the last drug intake.

Dependence and withdrawal syndrome

The use of Concerta (Methylphenidate) together with other strong substances or alcohol is particularly dangerous. Chronic abuse can cause tolerance and psychological dependence.

  • confusion and depression;
  • hunger;

Concerta headache

Headaches are a possible side effect of taking stimulants such as Concerta (Methylphenidate). This symptom usually appears at the beginning of ADHD medication and occurs every time the medication is taken.

What you should know about brand and generic drug alternates.
Prescription drugs are a costly medical expense, especially for the elderly, those who are chronically ill and those with no or minimal drug coverage on their Health Insurance. However, each state in America has a law that allows pharmacists to substitute less expensive generic drugs for many brand name products. Depending on your prescription needs, your savings could be very significant. Before you talk with your doctor or pharmacist about switching, there are things you should know about generic drugs.

What is the difference between a generic and brand name drug?
Nothing except for the name, packaging, and the price, a generic drug is called by its chemical name; manufacturers assign their own brand name. The generic products have the same ingredients. Standard practice and most state laws require that a generic drug be generically equivalent to its brand name counterpart. That is, it must have the same active ingredients, strength, and dosage form, be it a pill, liquid, or injection. The generic drug also must be therapeutically equivalent. It must be the same drug chemically and have the same medical effect.

Do all drugs have generic equivalents?
No. Some drugs are protected by patents and are supplied by only one company. However, when the patent expires, other manufacturers can produce its generic version. Currently, about half the drugs on the market are available in generic form.

Will my doctor automatically prescribe generic drugs?
It depends on the physician. You can ask your doctor to write a prescription permitting substitution of a generic drug product when appropriate or to define the chemical name for the prescription. This will ensure you are purchasing the correct Mexico drug. Generic products will be as effective and less costly. Or, you can order only brand name products if you wish. Mexico pharmacy offers a wide selection of both Brand Name & Generic Mexico medicine. Our Mexican generic drugs are of the highest quality, selected only from the most reputable manufacturers, and are safe to replace brand name medications costing much more.
