Safety Announcement 
 
 [12-17-2013] The U.S. Food and Drug Administration (FDA) is warning that methylphenidate products, one type of stimulant drug used to treat attention deficit hyperactivity disorder (ADHD), may in rare instances cause prolonged and sometimes painful erections known as priapism. FDA continues to monitor the safety of drugs after they are approved, and, based on a recent review of methylphenidate products, we have updated the drug labels and patient Medication Guides to include information about the rare but serious risk of priapism. Patients who take methylphenidate and develop erections lasting longer than four hours should seek immediate medical treatment to prevent long-term problems with the penis. If not treated right away, priapism can lead to permanent damage to the penis. 
 
 Priapism can occur in males of any age and happens when blood in the penis becomes trapped, leading to an abnormally long-lasting and sometimes painful erection. Younger males, especially those who have not yet reached puberty, may not recognize the problem or may be embarrassed to tell anyone if it occurs. All male patients and their caregivers should be taught the signs and symptoms of priapism and the importance of seeking immediate medical treatment if it occurs. 
 
 Methylphenidate products are among the medicines that can be used to treat ADHD. One of the most common childhood brain disorders, ADHD can continue through adolescence and adulthood and causes symptoms such as difficulty staying focused and paying attention, difficulty controlling behavior, and hyperactivity. Medications such as methylphenidate used to treat ADHD benefit patients with the disorder by increasing focus, reducing impulsivity, and improving overall social functioning. Therefore, patients who have been prescribed a methylphenidate product should not stop taking it without first talking to their health care professionals. Table 1 lists methylphenidate products marketed in the United States. 
 
 In our review, the median age of patients taking a methylphenidate product who experienced priapism was 12.5 years (range 8 to 33 years). In a few patients, priapism occurred after an increase in the dosage of methylphenidate, but priapism has also occurred under other conditions, such as during short periods of time when the drug was stopped temporarily, when there was a longer than typical time between doses, or after stopping the drug permanently. Two patients required surgical intervention; one required shunt placement, and the other had to have needle aspiration of the corpus cavernosum. 
 
 The risk of priapism may cause some health care professionals toconsider switching patients to the non-stimulant drug Strattera (atomoxetine), another drug used to treat ADHD; however, atomoxetine has also been associated with priapism in young children, teenagers, and adults. Priapism appears to be more common in patients taking atomoxetine than in patients taking methylphenidate products. Health care professionals should be cautious when considering changing patients from methylphenidate to atomoxetine. 
 
 Amphetamine products are also used to treat ADHD, and we have received reports of priapism in four patients taking an amphetamine product. However, whether the amphetamine products caused the priapism is uncertain, because all of these patients had been taking other medications that are thought to cause priapism. Therefore, we cannot conclude that the use of amphetamine products can result in priapism. ||||| Warning to Ritalin users from the FDA: You may get the shaft 
 
 As if kids with ADHD didn’t have enough difficulty paying attention in class, now they have a whole new set of concerns. Well, the boys at least. 
 
 According to a report released this week by the FDA, one of the drugs that’s used to help kids with ADHD “may in rare instances cause prolonged and sometimes painful erections known as priapism. …If not treated right away, priapism can lead to permanent damage to the penis.” 
 
 The chemical, methylphenidate—which is in drugs like Ritalin—is a stimulant that affects the body’s central nervous system. So far, reported incidents of priapism from ADHD medicine erections are very rare (there have been 15 documented cases from 1997 to 2012) but the consequences are serious. 
 
 “Two patients required surgical intervention; one required shunt placement, and the other had to have needle aspiration of the corpus cavernosum.” 
 
 Ironically, another drug used to treat ADHD—Adderall—has the opposite effect. It causes impotence among many men who use it, proving that dudes with ADHD just can’t catch a break.

 The agency, in a notice on its website, said its review documented the problem, formally known as priapism, in males 8 to 33 years of age who took drugs containing methylphenidate. The chemical is the active ingredient of Novartis AG's Ritalin and Johnson & Johnson's Concerta. Generic forms of both drugs are also widely used. 
 
 Drug labels of such products will be updated to warn of the potential but rare danger, the FDA said. 
 
 "Younger males, especially those that have not yet reached puberty, may not recognize the problem or may be embarrassed to tell anyone if it occurs," the FDA said. 
 
 The agency said patients developing erections lasting more than four hours should seek immediate medical attention to prevent permanent damage to the penis. 
 
 A non-stimulant drug also used to treat attention deficit hyperactivity disorder, Eli Lilly and Co's Strattera, has also been linked to priapism in young children, teenagers and adults. Strattera, whose chemical name is atomoxetine, appears to pose a greater risk than methylphenidate products, the FDA said. 
 
 "Health care professionals should be cautious when considering changing patients from methylphenidate to atomoxetine" products, the agency said.

– Labels on Ritalin and other drugs used to treat ADHD will soon have a new warning: Beware long, painful erections. It seems that a chemical in the drugs called methylphenidate is a stimulant that can mess with the body's central nervous system, explains Vocativ.com. It “may in rare instances cause prolonged and sometimes painful erections known as priapism," says an FDA warning. Cases have been seen in kids as young as 8 years old, notes Reuters. "Younger males, especially those that have not yet reached puberty, may not recognize the problem or may be embarrassed to tell anyone if it occurs," says the FDA. And that's a real concern because the problem can cause permanent damage to the penis. Methylphenidate is found in Ritalin, rival Concerta, and generic forms of both.
