Attention deficit hyperactivity disorder (ADHD) is a common condition, affecting approximately 10% of American youth. With growing rates of ADHD, the prescription of stimulant medications is becoming more common. These medications can have several side effects, including muscle pain and stiffness. While stimulant medications can improve muscle tension for some patients, they can also cause muscle twitching, pain, cramping, and stiffness. Lisdexamfetamine, an amphetamine stimulant, is well-known to cause these symptoms, and there are reports of similar effects with dextroamphetamine-amphetamine. Non-stimulant medications, such as methylphenidates, have not been widely associated with muscle pain and stiffness without other serotonin-related symptoms. However, rare cases of severe muscle pain due to methylphenidate therapy have been documented. Additionally, ADHD medications can affect muscle endurance and fatigue tolerance, influencing exercise performance. It is important for healthcare providers to be aware of these potential side effects when prescribing medications and for patients to consult their doctors if they experience any adverse reactions.

Dexmethylphenidate may cause muscle pain and stiffness
Dexmethylphenidate is a stimulant medication used in the treatment of attention deficit hyperactivity disorder (ADHD). It is one of the most commonly prescribed medications for ADHD, with growing rates of diagnosis and treatment. Dexmethylphenidate, and potentially other methylphenidates, may cause severe muscle pain and stiffness. This is considered a rare but significant side effect of the medication.
Muscle pain and stiffness have been reported in some patients with untreated ADHD, and stimulant medications have been reported to improve muscle tension in some of these patients. However, dexmethylphenidate therapy has been linked to severe muscle pain and stiffness in some cases. There is a reported case of a 12-year-old boy, Kyle (pseudonym), who was prescribed dexmethylphenidate extended-release capsules to assist with school performance. Over several months, as the dosage was gradually increased, Kyle's muscle pain and stiffness, predominantly in his thighs, became so severe that he was unable to participate in physical education or after-school sports.
It is important to note that muscle pain and stiffness are not common side effects of non-amphetamine stimulant medications like dexmethylphenidate. An extensive literature review found only one case of a child experiencing muscle pain while taking methylphenidate, and that child presented with additional symptoms such as abdominal pain and leg pain. However, as in Kyle's case, severe muscle pain and stiffness can occur with dexmethylphenidate use.
If a patient with ADHD develops severe muscle pain and stiffness while taking dexmethylphenidate, it is recommended that healthcare providers consider medication side effects as a possible cause. A trial off the medication may be suggested to determine if the symptoms resolve, and physical therapy may be beneficial during this period. In Kyle's case, his muscle pain resolved several weeks after discontinuing dexmethylphenidate, and his muscle stiffness improved with physical therapy.
While dexmethylphenidate may cause muscle pain and stiffness, it is important to weigh the risks and benefits of the medication. ADHD medications can enhance the effect of dopamine on the body, increasing motor activity and muscular endurance. They can also reduce the feeling of fatigue during exercise. However, an excess of these stimulant-type drugs may increase the occurrence of tremors and irregular involuntary muscle contractions, which can increase the risk of injury. Therefore, it is crucial for healthcare providers to be aware of the potential side effects and monitor patients closely to ensure excellent care.

Lisdexamfetamine causes muscle pain, cramping, and stiffness
Lisdexamfetamine is a stimulant medication used to treat attention deficit hyperactivity disorder (ADHD) and binge eating disorder. It is available as Vyvanse and generic lisdexamfetamine in oral capsule and chewable tablet dosage forms.
Lisdexamfetamine is well-known to cause muscle pain, cramping, and stiffness in some patients. Muscle twitching, stiffness, and tremors are also common side effects of the medication. These side effects have been most widely reported with lisdexamfetamine, although there is some data suggesting that the combination medication dextroamphetamine-amphetamine may cause similar symptoms.
Lisdexamfetamine can also cause circulation problems, including Raynaud's syndrome, which can make fingers and toes feel cold, numb, and painful. The skin may turn blue or pale when it is cold or the patient is stressed, then turn red as the patient warms up. Contact your healthcare provider if you experience these symptoms.
Lisdexamfetamine may also cause allergic reactions, which can be serious. Stop taking the medication and seek medical help immediately if you experience any of the following symptoms: breathing problems or wheezing, racing heart, fever or general ill feeling, swollen lymph nodes, swelling of the face, lips, mouth, tongue, or throat, trouble swallowing or throat tightness, itching, skin rash, hives, nausea or vomiting, dizziness, lightheadedness, fainting, or stomach cramps.
Lisdexamfetamine has a high potential for abuse and misuse, which can lead to the development of a substance use disorder, including addiction. It is important to assess each patient's risk for abuse, misuse, and addiction before prescribing lisdexamfetamine and to educate patients and their families about these risks.

Adderall and stimulants may cause muscle pain
Adderall and other stimulants may cause muscle pain, cramping, and stiffness. Dexmethylphenidate, a medication used to treat ADHD, can cause severe muscle pain and stiffness. Lisdexamfetamine, an amphetamine stimulant, is also known to cause muscle pain, cramping, and stiffness. Other amphetamine stimulants, such as dextroamphetamine-amphetamine, may have similar effects. These medications can also lead to serotonin syndrome, resulting in severe muscle twitching, rigidity, and loss of muscle coordination.
While stimulant medications can improve muscle tension for some patients with untreated ADHD, they may also increase the occurrence of involuntary muscle contractions, tremors, and myoclonus, which can elevate the risk of injury during movement. Additionally, ADHD medications can enhance dopamine levels in the body, increasing motor activity and muscular endurance while reducing muscle fatigue. However, a study on methylphenidate, a noradrenaline reuptake inhibitor, found that this type of ADHD medication may cause the body to fatigue more quickly during prolonged exercise.
It is important to note that muscle pain and stiffness have also been reported in some patients with untreated ADHD. Furthermore, certain medications, including Adderall, have been associated with rhabdomyolysis, a life-threatening condition where muscle fibers break down, releasing a protein called myoglobin that can damage the kidneys. Patients experiencing unexplained muscle pain while taking Adderall or other stimulants should consult their doctor immediately, as discontinuing the medication may be necessary.
While the exact mechanism is unknown, stimulant medications can sometimes cause or worsen tics, which are involuntary, unpredictable, repetitive movements, spasms, or gestures. These tics can involve the eyes, face, mouth, neck, or shoulders, and may include sniffing, humming, or coughing if the throat muscles are affected.
If you are experiencing muscle pain or other side effects from ADHD medications, it is important to consult your healthcare provider. They may recommend adjusting the medication dosage, trying a non-stimulant medication, or prescribing additional treatments to manage muscle pain and stiffness.

Stimulant medications can cause muscle twitching
Muscle pain and stiffness are common side effects of stimulant medications used to treat ADHD. Dexmethylphenidate, a type of methylphenidate, is known to cause severe muscle pain and stiffness in some patients with ADHD. Lisdexamfetamine, an amphetamine stimulant, is also associated with muscle pain, cramping, and stiffness. These symptoms can also occur without other serotonin-related issues in some cases.
Amphetamine stimulant medications, including lisdexamfetamine and dextroamphetamine-amphetamine, have been linked to muscle pain, cramping, and stiffness. In contrast, methylphenidate stimulants are considered less likely to cause these symptoms, although rare cases have been reported. For instance, an adolescent male experienced severe muscle pain and stiffness due to methylphenidate therapy.
Additionally, ADHD medications can increase muscular endurance and reduce muscle fatigue during exercise. However, an excess of these stimulant medications may increase the occurrence of tremors and myoclonus in muscle tissue, leading to irregular involuntary muscle contractions and a higher risk of injury during movement. Furthermore, ADHD medications can cause unpredictable muscle contractions, affecting the ability to exercise efficiently and perform stable movements.
It is important to note that muscle pain and stiffness have also been observed in some patients with untreated ADHD. While stimulant medications can improve muscle tension in some of these patients, they can also trigger or worsen tics, which are involuntary, unpredictable, repetitive movements or spasms. In rare cases, ADHD medications have been associated with rhabdomyolysis, a life-threatening condition where muscle fibres break down, releasing a protein that can damage the kidneys.

ADHD medications can increase muscular endurance
ADHD medications, most of which are stimulant-based, can enhance the effect of dopamine on the body. This increases motor activity and muscular endurance, while also reducing the feeling of fatigue while exercising. However, an excess of these stimulant-type drugs may increase the occurrence of tremors and myoclonus in muscle tissue, leading to a higher risk of injury during movement.
A study on methylphenidate, a noradrenaline reuptake inhibitor, found that this type of ADHD medication can cause the body to fatigue more quickly when enduring prolonged exercise. The study showed that different ADHD medications can impact exercise performance and muscle endurance.
Stimulant medications used for ADHD treatment are believed to provide a physical advantage in athletics. Six reports found significant improvement in athletic performance with the use of stimulant medications. For example, amphetamine, at a dose of 15 mg per 70 kg body weight, was evaluated via cycling and running trials, with findings of increased acceleration, knee extension strength, and time to exhaustion. However, the potential for stimulant medications to cause harm is the predominant reason for their avoidance in the athletic population.
Amphetamines have been found to increase synaptic dopamine and norepinephrine levels in multiple brain regions, particularly in the striatum, while also increasing global cerebral blood flow. Methylphenidate, another type of ADHD medication, inhibits dopamine and norepinephrine transporters, thereby increasing extracellular dopamine and norepinephrine, as well as activating adrenergic receptors and stimulating cortical excitability.
While ADHD medications can increase muscular endurance, they may also cause muscle aches. Dexmethylphenidate and potentially other methylphenidates used in ADHD treatment may cause severe muscle pain and stiffness. Lisdexamfetamine, an amphetamine stimulant medication, is also well-known to cause muscle pain, cramping, and stiffness in some patients. Muscle twitching is a well-described side effect of stimulant medications, and they can also lead to serotonin syndrome, which may include severe muscle twitching, rigidity, and loss of muscle coordination.
