How Long Does Concerta Last?

Key Points

• Concerta is a stimulant medication used to treat attention-deficit hyperactivity disorder (ADHD) in children and adults.
• This extended-release medication lasts between six and ten hours, depending on various factors.
• Concerta is a Schedule II substance with high abuse potential. Only use as directed.

Finding the proper medication is only part of properly managing your ADHD symptoms. Timing is also an essential piece of the puzzle, directly affecting your daily routine and productivity.

Prescription ADHD medications like Concerta are formulated with extended-release capability to provide more consistent symptom management throughout the day. Understanding how long this medication exerts its effects can help you better plan your day for improved productivity.

Whether you’re just starting a treatment plan or your healthcare provider is adjusting your current regimen, knowing how long Concerta lasts in certain circumstances (dosage and other factors affect duration) is key to finding your . 

How Concerta Works

The active ingredient in Concerta is methylphenidate. Methylphenidate is a central nervous system (CNS) stimulant that increases the uptake of chemical messengers in the brain.[1] 

Specifically, methylphenidate works by blocking the ability of nerves to reabsorb the chemical messengers dopamine and norepinephrine. This increases the concentration of these chemical messengers in the space between nerves, creating a classic stimulant effect.[2]

Concerta uses a special oral delivery system (osmotic-controlled release oral delivery system, or OROS) to allow the drug to release gradually throughout the day.[3] This is why it’s important to never crush or chew the medication, as this will cause it to be released too quickly. 

Who Is Concerta For?

Concerta is primarily prescribed to manage attention-deficit hyperactivity disorder (ADHD) symptoms in children and adults. The FDA has approved this medication for use in patients six years and older.[4] 

There are several underlying medical conditions that can increase your risk of experiencing adverse effects (or decrease effectiveness) when using Concerta. These conditions include glaucoma, severe hypertension, and Tourette syndrome. 

Key symptoms Concerta addresses include:[5]

• Inattention: Difficulty focusing on tasks or following instructions
• Hyperactivity: Excessive movement and restlessness
• Impulsivity: Acting without thinking about consequences

In other words, Concerta helps people with ADHD function better in school, work, and social situations.

Common Side Effects

Like all medications, Concerta can cause side effects. Most side effects are mild and temporary, but serious side effects are still possible.

Common side effects of Concerta include:[6]

• Appetite loss: Reduced hunger, especially during lunch hours
• Sleep difficulties: Trouble falling asleep at bedtime
• Mood changes: Increased irritability or mood swings
• Physical symptoms: Headaches, stomach pain, or increased heart rate

Many side effects decrease as your body adjusts to the medication. However, persistent or severe symptoms require medical attention.

How Long Does Concerta Last?

When you take Concerta, your blood concentration of the drug increases rapidly for one hour.[7] Concentration will then increase gradually for the next five to nine hours, after which a gradual decrease begins. Peak concentration typically occurs between the six- and ten-hour mark.

Standard Duration by Dosage

Taking a higher dose of Concerta doesn’t guarantee that you will experience symptom relief for a longer period of time. Rather, higher doses typically provide stronger symptom control within the same time frame.[8]

This doesn’t mean that individual responses can’t vary significantly. Metabolism, age, and several other individualized factors can cause some people to experience the effects of Concerta for a shorter or longer window of time. 

How long does 18mg Concerta last? Typically, between ten and twelve hours. Many patients find this dosage level to be adequate for consistent symptom management. Whether or not this is the most effective dose for you should be determined in a conversation with your healthcare provider.

Factors Affecting Duration

Here’s a closer look at the factors that can influence how long Concerta lasts:

Body weight and metabolism can significantly affect how long you may experience the effects of Concerta. People with faster metabolisms may process the medication more quickly.

Age also influences the effects of methylphenidate. This finding shows that children and adults may metabolize methylphenidate differently.[9]

Food intake can impact absorption, depending on the food. Taking Conceta with a high-fat meal may slightly delay the onset of action, but is unlikely to affect total duration.

Individual differences in brain chemistry can create unique responses to Concerta, including but not limited to the duration of its effects. 

It’s also highly important that you make sure your care provider is updated on any and all medications you’re taking and any underlying conditions you have. 

Concerta may affect your body’s ability to break down drugs like warfarin, SSRIs (selective serotonin reuptake inhibitors), and others.[10] It may also increase the risk of harmful symptoms when combined with risperidone. 

How Long Is Concerta In Your System?

Concerta remains in your system after the therapeutic effects have faded away. This medication has a half-life of roughly three to four hours.[11] 

In most cases, this means you can expect the medication to take roughly 24 to 48 hours to be eliminated entirely by the body. Many of the same factors that affect how long Concerta lasts also influence this window.

Abuse Potential and Safety Considerations

Concerta is classified alongside other methylphenidate products as a Schedule II controlled substance.[12] 

According to the Drug Enforcement Administration’s (DEA) drug scheduling system, Schedule II drugs are defined as “drugs with a high potential for abuse, with use potentially leading to severe psychological or physical dependence.”[13] 

Common signs of Concerta misuse include taking larger doses than you were originally prescribed, crushing or snorting tablets (bypassing the extended-release effect), or using the medication without a prescription. 

Taking the medication exactly as directed, checking in with your healthcare provider(s) on a regular basis and/or when there are any concerns, is essential for minimizing your risk of developing dependence or severe side effects. 

When to Consult Your Healthcare Provider

Contact your doctor if Concerta’s effects seem to fade too quickly. You might need a dosage adjustment or different medication timing.

Persistent side effects warrant medical attention. Your provider can adjust doses or explore alternative treatments.

Meanwhile, significant mood changes require immediate consultation. While rare, some people experience depression or anxiety with stimulant medications.
