Methylphenidate extended-release (ER) is a first-choice option for people with attention deficit-hyperactivity disorder (ADHD). This once-daily medication can start to work within 2 hours and can last throughout the day. Methylphenidate ER can cause difficulty sleeping and a loss of appetite. It also has a potential risk of misuse and dependency and is thus a controlled substance.
Methylphenidate ER is a stimulant medication. It's not exactly known how methylphenidate ER helps to improve attention and focus. But it's thought to work by raising the levels of chemicals in your brain called norepinephrine and dopamine. It's also thought to boost the activity of serotonin in the brain.
Methylphenidate ER can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Methylphenidate ER has a risk of misuse and dependence. Misuse is when a medication is used differently than how it's prescribed. Misusing methylphenidate ER raises your risk for serious side effects such as fast heart rate, high blood pressure, aggressive behavior, and even thoughts of hurting yourself.
In addition, over time, you can become physically dependent on methylphenidate ER to function normally. This is usually related to having withdrawal symptoms like irritability, nightmares, and sleep problems if you take the medication for a long time and then suddenly stop. Take the medication exactly as prescribed to you. Don't change the dose or how often you take it without talking to your provider first.
There have been reports of sudden death, stroke, and heart attack in people who took methylphenidate ER at usual doses. Methylphenidate ER can also raise your blood pressure and heart rate. Tell your provider if you have a history of heart problems before starting methylphenidate ER to make sure it's safe for you to take. Your provider will check for heart problems before starting treatment with this medication. Contact your provider if you experience unexplained fainting, chest pain with physical activity, or irregular heartbeat while you're taking methylphenidate ER.
Taking a stimulant like methylphenidate ER can cause mental health problems such as hallucinations (seeing things that aren't really there), abnormal or unclear thinking, and mania. This medication can worsen mood-related problems that you already have. But these changes in mood or behavior can also happen even if you haven't had these problems before. If you develop these mood- and behavior-related symptoms while taking methylphenidate ER, talk to your healthcare provider right away because you might have to stop taking it.
Although rare, some people taking methylphenidate ER experienced prolonged and painful erections. Sometimes, it might require surgery to treat. This was typically reported after the dose was raised, but could also happen when the medication was stopped. If you develop a painful erection that lasts longer than 4 hours, stop taking methylphenidate ER and get medical attention immediately.
Methylphenidate ER might be linked to poor blood circulation problems, such as Raynaud's phenomenon. People with Raynaud's phenomenon can experience episodes of poor blood flow to the fingers and toes, which can cause the skin to turn pale and to feel cold, numb, or painful. If this happens, symptoms are typically mild. But rarely, it can cause sores or ulcers in more serious cases. Let your healthcare provider know if you notice symptoms of circulation problems, such as bouts of numbness or pain in your fingers or toes. Your provider might need to lower your dose of methylphenidate ER or ask you to consider a different medication.
In studies, children taking stimulants like methylphenidate ER daily throughout the year had a temporary slowing of growth. On average, the children in these studies had 2 cm less growth in height and 6 pounds less growth in weight over 3 years. Your child's provider will track your child's growth progress closely. If they suspect slowed growth, they might pause or stop your child's methylphenidate ER treatment. Talk to your child's provider if you have concerns.
Serotonin syndrome is a rare, but potentially life-threatening condition where there's too much serotonin in the brain. Serotonin is one of the chemicals in your brain responsible for your mood. Your risk for this condition goes up if you use methylphenidate ER with other medications that affect serotonin levels, such as antidepressants (e.g., sertraline (Zoloft), duloxetine (Cymbalta)), MAOIs (e.g., phenelzine (Nardil)), linezolid (Zyvox), and certain migraine medications (e.g., sumatriptan (Imitrex)). Let your provider know about all the medications you take or plan to take before starting methylphenidate ER. Be aware of symptoms of serotonin syndrome, which include fast heart rate, sweating, muscle stiffness or spasms, high fever, and confusion. Get medical help right away if you have any of these symptoms.
Methylphenidate ER can interact with a lot of medications. Methylphenidate ER counteracts (works against) the effects of many blood pressure medications. This means your blood pressure medications might not work as well for you if you take them with methylphenidate ER. Additionally, avoid taking methylphenidate ER with monoamine oxidase inhibitors (MAOIs). This combination can raise your risk of severely high blood pressure. Discuss with your healthcare provider and pharmacist about all the medications you take (including over-the-counter medications and supplements) before and during treatment with methylphenidate ER.

Yes. According to the ADHD treatment guidelines, stimulant medications like methylphenidate ER used along with other behavioral therapies are first-choice options for children. Healthcare providers also use methylphenidate ER often for adults with ADHD. Stimulant medications generally work well to improve attention span. But they're not always for everyone since taking the medication can have many risks. Talk with your provider about whether methylphenidate ER is an appropriate option for you.
Methylphenidate ER and Adderall XR (dextroamphetamine / amphetamine salts) are both stimulants that treat ADHD. They have similar side effects and potential risks. But ADHD experts might recommend these two medications for different age groups based on studies looking at how well they work and how safe they are. Adderall XR (dextroamphetamine / amphetamine salts) might be the preferred choice for adults, whereas methylphenidate ER might be the preferred choice for children and adolescents. In addition, methylphenidate ER is available in many different formulations (e.g., chewable tablet, oral liquid), whereas Adderall XR (dextroamphetamine / amphetamine salts) is only available as capsules. Speak with your provider about the appropriate choice for you if you need medication to treat your ADHD.
There are several brands of methylphenidate ER available on the market today. These brands differ by formulation. They come as oral tablets (e.g., Concerta), capsules (e.g., Jornay PM), chewable tablets (QuilliChew ER), oral liquid (Quillivant XR), and even patches placed on the skin (Daytrana). The brands also differ in cost and whether they're available as a lower-cost generic. Insurance companies might only cover certain brands of methylphenidate ER. Discuss with your provider about which brand or formulation fits your needs.
If you're pregnant or thinking of getting pregnant, discuss with your provider about the risks and benefits of taking methylphenidate ER. More research is needed to know for sure if it's safe to take during pregnancy. But some studies suggest that people who took methylphenidate ER during pregnancy might be at risk of developing high blood pressure during pregnancy (preeclampsia), having an early (preterm) delivery, or having possible harm to the baby. In addition, newborn babies might have a low birth weight. If you're currently pregnant and taking this medication, it's encouraged that you enroll in the National Pregnancy Registry for ADHD Medications, which monitors your and your baby's health. Enroll in this registry by calling 1-866-961-2388 or by visiting their website.
Talk to your provider about the risks and benefits of breastfeeding while taking methylphenidate ER. Limited research suggests methylphenidate ER can get into breast milk. This might raise the risk of serious side effects in your nursing baby (e.g., blood pressure or heart rate changes, growth problems, low appetite).
