Concerta Usage, Side Effects and Interactions

Concerta is used to treat ADHD in children, adolescents and adults. Adverse reactions occur in some patients, so work with your doctor to determine an appropriate dose.

Concerta is a CNS stimulant that is used to assist in the treatment of Attention Deficit Hyperactivity Disorder, also known as ADHD. This medication will not cure ADHD, but it can help make the symptoms less bothersome so the patient can function more effectively on a day to day basis. Though side effects are not usually dangerous or life threatening, they are quite common, so you should work closely with your doctor to monitor your dosage. This will help minimalize your risk of developing a negative reaction.

Indications and Usage

Concerta is the brand name for the stimulant methylphenidate HCI. The drug is given in extended release tablets that help patients manage their ADHD symptoms more effectively. Tablets are taken once a day with or without food. You should not crush, chew or split Concerta tablets when taking your dose. It may be used alongside other methylphenidate medications if your doctor deems this necessary. The doses of each of these medications will need to be adjusted to compensate for these changes.

This medication is intended for those aged 7 or older that have shown intense symptoms of ADHD for a number of months. If your child has not shown multiple symptoms of this disorder on a regular basis for at least 6 months, then you should not start them on a Concerta regimen. Patients who appear to be reacting to an environmental stimulus which is contributing to their ADHD symptoms are not to be treated with this drug, but may see better results from psychosocial therapy. Talk with your doctor about these stimulants or your treatment options before committing to your prescription or starting your child on any medication.

Concerta Dosage

The recommended dose for adults begins at 10 mg per day or 36 mg per day depending on the severity of the symptoms. Doses should not exceed 72 mg per day for adolescents or adults under the age of 65. Children using Concerta who have never used a methylphenidate product before are typically started on 18 mg daily, which can be increased in weekly intervals to 54 mg per day as necessary. Doses will be increased based on how the body reacts to the mediation and the severity of the symptoms the patient shows. Children under 6 should not use Concerta due to the increased risk of side effects. Similarly, the safety of prescribing Concerta to patients over the age of 65 has not been established, so this age group should use extreme caution.
