1Concerta is a medication widely known in the treatment of attention deficit hyperactivity disorder (ADHD) in children and adults. Methylphenidate, which is the active ingredient in Concerta, stimulates the central nervous system. Concerta-Methylphenidate is a dosage form designed to release the active ingredient gradually throughout the day, allowing the therapeutic effect to be maintained over a long period of time.
Dosage
The dosage of Concerta depends on many factors, including the patient's age, weight, severity of ADHD symptoms, and the presence of other medical conditions. Proper dosage is a key aspect of successful treatment. Here are Concerta dosing recommendations for various conditions:
- Children with ADHD: For children ages 6 to 12 years, it is generally recommended to start with a Concerta dose of 18 or 27 mg daily, taken in the morning. The dosage can be increased each week until an optimal effect is achieved.
- Adolescents and adults with ADHD: Age-appropriate patients (12 years and older) are usually recommended to start at a dose of 18 or 36 mg per day. For some patients, a dose of 27 mg per day may also be sufficient. Further dose increases may be evaluated on an individual basis, with a maximum recommended dose of 72 mg per day.
- Patients with impaired renal or hepatic function: For patients with impaired renal or hepatic function, it is generally recommended to start with lower doses and carefully monitor the response to the drug. Doses may be adjusted according to the degree of organ dysfunction.
- Maintaining the effect of treatment: To maintain the effect of treatment, usually take one dose per day in the morning. If the effect decreases or side effects occur, the dose or regimen may need to be adjusted.
- Individual response to the drug: It is important to consider a patient's individual response to Concerta when determining the optimal dose. Lower doses may be sufficient for some patients, while others may require higher doses.
When prescribing a dose of Concerta, the physician considers all of the above factors and decides on the most appropriate treatment strategy for each patient. It is important to follow the doctor's instructions and not change the dosage on your own without his approval to avoid possible undesirable consequences.
For some patients, Generic Concerta, which also contains methylphenidate, may be a more affordable treatment option. However, it is important to take into account that the bioequivalence of generics may differ, so it is necessary to coordinate their use with a doctor.
Contraindications
- Hypersensitivity to methylphenidate: People with known hypersensitivity to methylphenidate or other components of Concerta should not take it.
- Glaucoma: Concerta should be avoided in patients with increased intraocular pressure or glaucoma.
- Tics: The drug should be used with caution in patients with the presence of tic disorders.
- Arterial hypertension and cardiac problems: Concerta should be used with caution in patients with arterial hypertension, cardiac abnormalities, or heart rhythm disorders.
- Concomitant administration of alcohol or other centrally acting drugs: Concerta should not be taken concomitantly with alcohol or other drugs that may affect the central nervous system.
Side effects
- Insomnia: Concerta may cause difficulty falling asleep or insomnia in some patients.
- Loss of appetite: A decrease in appetite, and therefore weight loss, is one of the most common side effects of Concerta, especially at the beginning of treatment.
- Headache: Some people may experience headaches or migraines while taking the drug.
- Nervousness and anxiety: In individual patients, Concerta may cause an increase in nervousness or anxiety.
- Dry mouth: This side effect occurs in some patients and usually goes away on its own.
Concerta reviews can be varied, as each person responds to the medication individually. Some patients report significant improvement in their ADHD symptoms and quality of life, while others may experience unpleasant side effects or insufficient effects from the medication.
Possible unwanted interactions of Concerta with other medicines
Some antidepressants, such as serotonin reuptake inhibitors (SSRIs) and serotonin and norepinephrine reuptake inhibitors (SNRIs), may increase the effects of Concerta and increase the risk of serotonin syndrome.
Antipsychotic drugs may increase unwanted side effects of Concerta, such as anxiety or agitation.
Concerta may decrease the effectiveness of anticonvulsant drugs such as carbamazepine or phenytoin.
Drugs used to treat hypertension may increase blood pressure when combined with Concerta.
Drugs used to treat obesity or to reduce appetite may interact with Concerta, increasing the loss of appetite leading to weight loss.
Choosing between analogs
Comparing Concerta with other drugs such as Adderall, Vyvanse and Ritalin is an important issue when choosing the most appropriate treatment. Each of these drugs has its own characteristics, advantages and disadvantages, and the choice should be tailored to the individual needs of the patient.
Concerta vs Adderall
Concerta contains methylphenidate, which is a central nervous system stimulant. It acts gradually, providing a steady release of the active ingredient throughout the day.
Adderall contains a mixture of amphetamine salts, which are also stimulants but may act more quickly and have a more short-term effect.
Concerta vs Vyvanse
Concerta contains methylphenidate, which is a central nervous system stimulant. It provides a gradual release of the active ingredient throughout the day.
Vyvanse contains lisdextroamphetamine, which is converted into the active ingredient (dextroamphetamine) in the body. This drug also provides long-lasting effects, but its release mechanism is different from Concerta. Vyvanse is known for its smoother onset and end of action, which may be preferable for some patients.
Concerta vs Ritalin
Concerta and Ritalin both contain methylphenidate, which is a central nervous system stimulant. They both help improve concentration and reduce hyperactivity and impulsivity in patients with ADHD.
Concerta is a prolonged-release form of the medication that provides a gradual release of methylphenidate throughout the day. The dosage can range from 18 to 54 mg per day.
Ritalin is available as tablets and capsules in various dosage forms, including extended-release (Ritalin LA) and immediate-release (Ritalin IR).

The price of Concerta can fluctuate depending on the location of sale, the specific pharmacy, and the manufacturer's pricing strategy. It is important to note that the cost of the drug should correspond to its quality and effectiveness. Therefore, before purchasing, it is recommended to conduct a thorough analysis and search for the most favorable offer.
In addition, it is possible to order and purchase Concerta online, which can be a convenient option for those who prefer home delivery or live in remote areas. However, when buying online, it is important to choose reliable and licensed pharmacies to avoid counterfeits.
In certain countries, such as Mexico, access to Concerta may be freer, and it can be ordered online without a prescription at a lower price.
Mechanism of duration of therapeutic effect and excretion from the body
Duration of action
Concerta has a prolonged action due to its special release form - it gradually releases the active substance, methylphenidate, over a long period of time. This is achieved due to the built-in release mechanism, which allows the drug to exert its effect on the body for 8–12 hours.
After taking Concerta, patients usually feel the onset of the drug's effects 1–2 hours after taking it, and its effects last throughout the day.
Release and excretion time
Concerta comes as a special extended-release capsule that contains methylphenidate in the form of microgranules coated with a special polymer coating. This coating allows methylphenidate to be slowly released from the capsule throughout the day.
The initial release occurs through an opening at one end of the capsule, and then the remainder of the methylphenidate is gradually released through special pores on the surface of the capsule.
Methylphenidate, the main active ingredient in Concerta, is metabolized in the liver to form inactive metabolites. These metabolites are then excreted from the body through the kidneys as urine.
The half-life of methylphenidate is about 2 hours, which means that the drug is completely excreted from the body about 10–12 hours after ingestion.
The excretion rate of Concerta may vary depending on a variety of factors, including age, gender, functional status of the liver and kidneys, and other individual body characteristics.
In conclusion, Concerta is an effective treatment for ADHD, but its use should be evaluated and monitored by a qualified physician based on the individual patient and medical conditions.
