ADHD, or attention deficit hyperactivity disorder, is a common neurodevelopmental disorder that affects both children and adults. Individuals with ADHD may struggle with attention, impulse control, and hyperactivity, which can significantly impact their daily lives. While there is no definitive cure for ADHD, there are several treatment options available, including medication. Two commonly prescribed medications for ADHD are Strattera and Intuniv. In this blog, we will explore the key differences between Strattera and Intuniv, their effectiveness, and their potential side effects to help you make an informed decision about which medication may be the better option for you or your loved one.
Key Takeaways
- Strattera (atomoxetine) works by increasing levels of norepinephrine and exerts an effect similar to some antidepressants. Caution must be exercised when combined with medications for managing depression and different forms of anxiety.
- Intuniv (guanfacine) is an alpha-adrenergic agonist, meaning it can be considered a stimulant. Its mechanism for ADHD management is ultimately ill-defined, although it affects moderation of norepinephrine and dopamine. It works differently than other stimulants used for ADHD, like amphetamines or methylphenidate, however.
- Both medications are non-controlled.
- These medications both need to be used consistently over time to remain effective. They cannot be taken only on school days, etc.
- A primary side effect of Intuniv is drowsiness and fatigue.
- Strattera has been associated with higher rates of stomach upset and decreased appetite. Monitoring growth parameters over time is important when administered to pediatric patients.
- Both medications are effective for the management of ADHD symptoms. These medications have not been studied head-to-head directly, but indirect studies have suggested that Intuniv may be more effective than Strattera across a broad population.
- Strattera metabolism is affected by CYP2D6, and Intuniv metabolism is affected by CYP3A4. Genetic testing may help predict individual responses to these medications.
Understanding ADHD
Living with ADHD can be challenging, both for individuals who are diagnosed with the disorder and for their families. ADHD is characterized by symptoms such as inattention, hyperactivity, and impulsivity. Children with ADHD may struggle to follow instructions, finish tasks, or stay organized, while adults may have difficulty with time management, organization, and goal setting. It's important to note that ADHD symptoms can vary in severity and presentation, and the impact of the disorder can extend beyond academic and occupational functioning to social interactions and overall quality of life.
What is ADHD?
ADHD, short for attention deficit hyperactivity disorder, is one of the most common neurodevelopmental disorders, affecting approximately 5-10% of children and 2-5% of adults worldwide. It is characterized by persistent patterns of inattention, hyperactivity, and impulsivity that interfere with daily functioning and development. ADHD is often diagnosed in childhood, but symptoms can persist into adolescence and adulthood. The exact cause of ADHD is unknown, but research suggests that a combination of genetic, neurological, and environmental factors contribute to its development. Effective treatment for ADHD typically involves a multimodal approach, including medication, behavioral therapy, and support from healthcare professionals, educators, and family members.
Common Symptoms of ADHD
The symptoms of ADHD can vary among individuals, but the three main types of ADHD are predominantly inattentive, predominantly hyperactive-impulsive, and combined type. Inattentive symptoms include difficulty sustaining attention, being easily distracted, forgetfulness, and trouble organizing tasks. Hyperactive-impulsive symptoms may manifest as excessive fidgeting, restlessness, impulsivity, interrupting others, and difficulty waiting turns. Combined type ADHD involves a combination of inattentive and hyperactive-impulsive symptoms. Other common symptoms of ADHD may include mood swings, irritability, low frustration tolerance, and difficulties with executive functions, such as planning, prioritizing, and self-regulation. It's important to note that not all individuals with ADHD will exhibit the same symptoms, and the severity of symptoms can vary.
Strattera for ADHD
Strattera is a medication commonly prescribed for the treatment of ADHD. Unlike stimulant medications, such as methylphenidate or amphetamines, Strattera is a non-stimulant medication known as atomoxetine. It is approved for use in children, adolescents, and adults with ADHD. Strattera works by increasing the levels of norepinephrine, a neurotransmitter involved in attention and behavior control, in the brain. This mechanism of action sets Strattera apart from other ADHD medications, as it does not directly affect dopamine levels. Consequently, Strattera does not have the potential for abuse and is not classified as a controlled substance.
How Strattera Works
Strattera, or atomoxetine, is classified as a selective norepinephrine reuptake inhibitor (SNRI). It inhibits the reuptake of norepinephrine, a neurotransmitter, which allows more norepinephrine to be available in the brain. Norepinephrine plays a role in attention, behavior control, and regulation of impulses. By increasing norepinephrine availability, Strattera helps improve attention and reduce hyperactivity and impulsivity in individuals with ADHD. The effects of Strattera are not immediate and may take several weeks to reach their full potential. It is important to note that while Strattera is effective for some individuals, it may not be as effective for others. Every individual responds differently to medication, and finding the right treatment plan often involves a process of trial and error.
Dosage and Administration of Strattera
The dosage of Strattera is determined by weight, and it is typically started low and gradually increased to find the optimal dose for each patient. Strattera is available in capsule form, and the capsules should be taken whole, not crushed or chewed, with water. It is important to carefully follow your healthcare provider's medication guide and prescription label instructions. Regular visits to the healthcare provider are essential to monitor treatment progress, adjust the dosage if needed, and discuss any concerns or side effects. Abrupt discontinuation of Strattera should be avoided, and it is important to discuss any changes in the medication regimen with a healthcare professional.
Side Effects and Precautions of Strattera
While Strattera is generally well-tolerated, it is important to be aware of potential side effects and precautions. Common side effects of Strattera may include:
- Loss of appetite: Some individuals may experience a decrease in appetite while taking Strattera. Monitoring weight and ensuring proper nutrition is important.
- Stomach upset: Symptoms ranging from upset stomach to nausea and vomiting can occur in some patients. Starting at a lower dose and raising the dose slowly over time can help prevent this.
- Dry mouth: This is a common side effect, but it can be managed by drinking plenty of fluids or using sugar-free candies or gum.
- Mood swings: Strattera can sometimes cause changes in mood or emotional regulation.
Less commonly, more serious side effects may occur, and these should be promptly reported to a healthcare professional:
- High blood pressure: Strattera can increase blood pressure, so regular monitoring of blood pressure is necessary.
- Liver disease: In rare cases, Strattera may cause liver problems. Signs of liver disease, such as dark urine, yellowing of the skin or eyes, or abdominal pain, should be reported to a healthcare provider immediately.
- Suicidal thoughts: Some individuals may experience changes in mood, including suicidal thoughts, while taking Strattera. Any unusual thoughts or mood changes should be discussed with a healthcare professional.
It's important to note that this is not an exhaustive list of side effects, and individual experiences may vary. It is crucial to discuss any concerns or side effects with a healthcare provider to determine the most appropriate course of action.
Intuniv for ADHD
Intuniv, also known as guanfacine extended-release, is another medication commonly prescribed for the treatment of ADHD. Unlike Strattera, Intuniv falls into the category of stimulant medications. Intuniv is not a controlled substance, however, which distinguishes it from therapeutic options like amphetamines or methylphenidate.
It is approved for use in children and adolescents with ADHD, and can be used as a standalone treatment or in combination with other stimulant medications. Intuniv works by targeting the prefrontal cortex, a region of the brain involved in attention, behavior, and impulse control, through selective activation of alpha-2A adrenergic receptors. This mechanism of action helps regulate norepinephrine, a neurotransmitter associated with attention and hyperactivity.
How Intuniv Works
Intuniv, or guanfacine extended-release, is in a class of medications known as selective alpha-2A adrenergic receptor agonists. It acts on the prefrontal cortex, a region of the brain involved in attention, impulse control, and behavior regulation, by selectively activating alpha-2A adrenergic receptors. The mechanism is ultimately ill-defined in ADHD management, but this activity can help reduce norepinephrine activity in the prefrontal cortex specifically, which helps improve attention and reduce hyperactivity and impulsivity in individuals with ADHD.
Unlike stimulant medications, such as methylphenidate or amphetamines, Intuniv does not directly affect dopamine levels in the brain. The exact mechanism of action of Intuniv in the treatment of ADHD is not fully understood, but it is believed to have a calming effect on hyperactive and impulsive behaviors.
Dosage and Administration of Intuniv
The dosage of Intuniv is determined based on weight and may vary from individual to individual. It is typically initiated at a low dose and titrated based on the individual's response and tolerability. Intuniv is available in extended-release tablets, which should be swallowed whole, not chewed, crushed, or broken, with water. The medication can be taken with or without food, as directed by the healthcare provider. It's important to follow the specific dosing instructions the healthcare provider provides, as individual needs may vary. Like Strattera, regular visits to the healthcare provider are necessary to monitor treatment progress, adjust the dosage if needed, and address any concerns or side effects. It is essential to store Intuniv at room temperature, away from moisture and heat, and out of reach of children.
Side Effects and Precautions of Intuniv
As with any medication, there are potential side effects and precautions associated with the use of Intuniv. Common side effects of Intuniv may include:
- Somnolence (drowsiness) and fatigue: Among individuals using Intuniv, drowsiness and sedation are the most common reasons for discontinuing therapy. These effects can increase over the first several weeks of dosing. Starting low and slowly increasing the dose can help avoid these effects.
- Low blood pressure: Intuniv can cause a decrease in blood pressure, leading to symptoms such as dizziness, lightheadedness, or fainting.
- Chest pain: Some individuals may experience chest pain while taking Intuniv. This should be reported to a healthcare professional.
- Trouble sleeping: Difficulty falling asleep or staying asleep may occur, particularly when Intuniv is taken in the late afternoon or evening.
Less commonly, more serious side effects may occur, and these should be promptly reported to a healthcare provider:
- Irregular heartbeat: Intuniv can affect heart rate, and any irregularities or changes in heart rate should be discussed with a healthcare professional.
- Dark urine: In rare cases, Intuniv may cause liver problems. Signs of liver disease, such as dark urine, yellowing of the skin or eyes, or abdominal pain, should be reported to a healthcare provider immediately.
- Allergic reaction: Some individuals may experience an allergic reaction to Intuniv, which can manifest as rash, itching, swelling, or difficulty breathing. Any signs of an allergic reaction should be promptly evaluated by a healthcare professional.
It's important to note that side effects can vary from individual to individual, and this is not an exhaustive list. If you have any concerns or experience side effects while taking Intuniv, it is crucial to consult with a healthcare provider for appropriate guidance and management.
