Concerta use and effects on the body 

Concerta is used to treat attention deficit and hyperactivity disorder (ADHD) in children 6 years of age and older when other treatments are not effective enough. Treatment is conducted under the supervision of a physician who has experience with childhood behavioral disorders. Therapy is aimed at stabilizing ADHD, which is characterized by:

  • chronic inability to concentrate for long periods, emotional instability
  • impulsiveness
  • moderate or severe hyperactivity
  • mild neurological symptoms
  • abnormalities on EEG recordings

Concerta: side effects

The decision to use the Concerta pill should be based on a careful assessment of the severity of the condition and consideration of age. For patients who are considering stimulant treatment, a thorough history and physical examination, including measurement of blood pressure and heart rate, should be performed. This is done to prevent possible adverse reactions, which include:

  • CNS disorders: insomnia, nervousness, headache, emotional lability, aggression, agitation, anxiety, depression, irritability, behavior disorders, mood swings, tics, insomnia, panic attacks, dizziness, dyskinesia, psychomotor hyperactivity.
  • Nasopharyngitis, upper respiratory tract infections, sinusitis.
  • Anorexia, decreased appetite, a moderate decrease in body weight gain.
  • Cardiovascular system disorders: arrhythmia, tachycardia, palpitations, increased blood pressure.
  • Hypersensitivity reactions, such as angioedema, anaphylactic reactions, ear edema, bullous reactions, skin flaking, urticaria, itching, skin rash, and eczema;
  • Upper abdominal pain is the most common complaint among children.

If these symptoms occur, you should see your doctor and work with him to adjust the correct dosage or to stop Concerta medication for a certain time. Some people may develop a dependence on Concerta medication while taking this drug for a long time. 

Not taking the medication can also lead to a state of dependence.

Symptoms of withdrawal symptoms include:

  •  A feeling of needing to take the medication daily
  • The feeling that you need to overdose on the drug to get the same effect 

If you have been addicted to drugs or alcohol, you should be meticulous when taking Concerta methylphenidate. This is because the risk of addiction to Concerta may increase. 

Concerta vs Adderall

Concerta and Adderall are used to treat attention deficit and hyperactivity disorder (ADHD). The main action is to activate the areas of the brain responsible for concentration. 

If you compare the two drugs, they are similar in many ways. Despite this, there are differences: 

  1. The active ingredient of Concerta is Methylphenidate. Adderall is an amphetamine (Dextroamphetamine).

  2. Form of release. Concerta is an oral tablet with a prolonged release. Adderall is immediate-release oral tablets or sustained-release oral capsules.

  3. The risk of withdrawal syndrome is possible with both drugs.

CNS stimulants such as Concerta and Adderall are also known to reduce appetite. For this reason, these drugs may cause weight loss in some people. Methylphenidate has a lower addictive potential than amphetamine, and therefore many doctors believe that Concerta is less addictive than Adderall. 

Concerta: dosages

Depending on your doctor's prescription, Concerta generic in half or whole tablet amounts is taken with or after meals. Initially, 5 mg is prescribed 1-2 times a day. The dose can be gradually increased every 7 days by 5-10 mg/day depending on tolerance and effectiveness to a maximum dose of 60 mg/day.

If the effect of the drug subsides too quickly and the patient has behavioral disorders or sleep problems, a small additional dose of the drug may be given in the evening. The patient's development, mental state, and cardiovascular function should be monitored during treatment. Treatment is usually discontinued during or after puberty.

Adults. Individuals in whom treatment with methylphenidate during childhood or adolescence has demonstrated clinically significant benefit may continue use after adulthood, initially at the same daily dose, but the dosage should be monitored regularly.

In patients who have not previously received methylphenidate, the dose should be adjusted individually, starting with the lowest possible dose based on treatment efficacy and tolerability assessment.

The recommended starting dose of Methylphenidate Concerta is 10 mg/day, which can be increased by 10 mg/day every 7 days if necessary. The total daily dose should be administered in 2 doses and taken in the morning and at noon. Continue treatment with the lowest effective dose. The maximum daily dose depends on the patient's body weight and should not exceed 1 mg/kg body weight; however, due to limited data from clinical trials on the use of doses >80 mg/day, the dose should not exceed 80 mg/day. Discontinue the drug if there is no improvement after one month of treatment.

Concerta: ADHD

Concerta has been shown in clinical trials to be effective in the treatment of ADHD in both adults and children. In our pharmacy, you can order Concerta online in various dosages. A mild CNS stimulant with a more pronounced effect on the psyche than on motor activity.

Is Concerta a stimulant?

The active ingredient in Concerta Methylphenidate is a CNS stimulant approved for the treatment of narcolepsy and attention deficit hyperactivity disorder (ADHD). Methylphenidate inhibits dopamine and noradrenaline reuptake; increased dopaminergic and noradrenergic activity in the prefrontal cortex may explain its effectiveness in ADHD. Many dosage forms are available and can be divided into short-, medium-, and long-acting methylphenidate. When deciding which dosage form is most appropriate for a given patient, two parameters are important to consider: the time to initial effect and the duration of action.

Concerta: weight loss

Concerta reduces appetite and increases metabolism, resulting in weight loss in some people. Clinical trials have shown 6.5% weight loss in the group of adults who took Concerta pills, compared to 3.3% in the group that took a placebo. 

Concerta and alcohol

 People who take alcohol and Methylphenidate Concerta may experience effects such as:

  • decreased motor reflexes
  • dizziness due to the interaction of alcohol and methylphenidate
  • nausea and vomiting 

 Taking enough Concerta increases the risk of heart failure. More serious side effects may include addiction, psychosis (delirium or hallucinations), delirium, mania, panic attacks, agitation, aggression, and seizures. 

Can Concerta cause depression?

Concerta refers to stimulants. As long as the patient takes the drug, there are no symptoms of depression.

It is the withdrawal of Concerta that can cause depression. It is the result of the body getting used to the increased levels of norepinephrine and dopamine in the brain from Methylphenidate Concerta. Stopping the drug suddenly causes these levels to plummet, leading to withdrawal symptoms. Major withdrawal symptoms include feelings of depression.

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.
