• Immediate-Release Tablets: Take the tablet by mouth with or without food. It’s typically taken once or twice a day, with the first dose in the morning and the second dose taken several hours later if necessary.
• Extended-Release Capsules: Swallow the capsule whole without crushing or chewing. The extended-release formulation is typically taken once a day in the morning.

If you experience any trouble swallowing the capsule, consult your doctor. They may recommend an alternative form of the medication or provide additional guidance.

Dexmethylphenidate works by increasing the levels of dopamine and norepinephrine in the brain. These neurotransmitters play an important role in regulating mood, attention, and behavior. By enhancing the activity of these chemicals in the brain, Dexmethylphenidate helps individuals with ADHD maintain focus, reduce hyperactivity, and improve their ability to control impulses.

While the exact way Dexmethylphenidate works in the brain is not fully understood, it is believed to block the reuptake of dopamine and norepinephrine into nerve terminals, thus increasing their concentration and activity at the synapses (the spaces between nerve cells).

Like all medications, Dexmethylphenidate can cause side effects. Some of the common side effects include:

• Insomnia: Difficulty sleeping is a common side effect, especially if the medication is taken later in the day.
• Appetite Suppression: Many individuals experience a decreased appetite, which may result in weight loss over time.
• Headache: Some people may experience headaches, especially when starting the medication or adjusting the dose.
• Increased Heart Rate: Dexmethylphenidate can cause an increase in heart rate, which may be problematic for individuals with pre-existing heart conditions.
• Nausea: Some people may feel nauseous, especially when taking the medication on an empty stomach.
• Anxiety or Nervousness: Anxiety or nervousness can occur, particularly in people sensitive to stimulant medications.
• Dry Mouth: Dexmethylphenidate may cause dry mouth, which can be uncomfortable but can usually be managed with frequent hydration or sugar-free gum.

Less common, but more serious side effects include:

• Chest Pain or Palpitations: Individuals who experience chest pain or irregular heartbeats should seek immediate medical attention.
• Severe Mood Changes: In some cases, Dexmethylphenidate may cause mood swings, depression, or aggressive behavior.
• Circulation Problems: Dexmethylphenidate can constrict blood vessels, leading to cold extremities or other circulation issues.

Contact your healthcare provider if you experience any of these more serious side effects.

• Heart Problems: Dexmethylphenidate should be used with caution in individuals with heart conditions, such as high blood pressure, heart disease, or a history of heart attacks.
• Mental Health Concerns: People with a history of mental health issues, such as anxiety, depression, or bipolar disorder, should be monitored closely while using Dexmethylphenidate.
• Substance Abuse Risk: Dexmethylphenidate is a stimulant and has a potential for abuse or addiction. It should be used only as prescribed and kept out of reach of others.
• Seizure Disorders: People with a history of seizures should use Dexmethylphenidate cautiously, as it can lower the seizure threshold.

Discuss any pre-existing conditions with your healthcare provider to ensure Dexmethylphenidate is a safe option for you.

Dexmethylphenidate can interact with several other medications, which may affect how it works or increase the risk of side effects. Some potential drug interactions include:

• Monoamine Oxidase Inhibitors (MAOIs): These medications, often used to treat depression, should not be used with Dexmethylphenidate due to the risk of serious, life-threatening side effects like a hypertensive crisis (severe high blood pressure).
• Antihypertensive Medications: Dexmethylphenidate may reduce the effectiveness of blood pressure medications, leading to increased blood pressure.
• Other Stimulants: Combining Dexmethylphenidate with other stimulant medications can increase the risk of side effects, such as increased heart rate, high blood pressure, and anxiety.
• Antidepressants (SSRIs, SNRIs): These can increase the risk of serotonin syndrome, a potentially life-threatening condition characterized by symptoms such as agitation, hallucinations, fever, and rapid heart rate.

Always inform your healthcare provider about all other medications you are taking, including over-the-counter drugs and supplements.

• For ADHD in Children (6 years and older): The typical starting dose is 2.5 mg to 5 mg once daily, with the dose adjusted as needed.
• For Adults with ADHD: The typical starting dose is 5 mg once or twice daily, which may be increased in increments of 5 mg each week to reach an optimal dose.
• For Narcolepsy: The dosage will depend on individual needs, with a starting dose generally being 5 mg once or twice daily.

Your healthcare provider will determine the best dosage based on your response to the medication and any other factors that may be relevant.

Dexmethylphenidate is a prescription-only medication, meaning you must have a prescription from a licensed healthcare provider to obtain it. It is classified as a Schedule II controlled substance due to its potential for abuse, so it is important to take this medication exactly as prescribed and not share it with others.
