An inferior vena cava (IVC) filter is a small cage-like medical device that can be inserted by doctors to stop dangerous blood clots from traveling to the blood vessels of the lungs. Their structure allows them to catch fragments of clots that form in the legs or pelvis before these blockages run the risk of causing a pulmonary embolism (PE). These metal filters are surgically implanted in patients who cannot tolerate blood thinners or have seen little success with those drugs.
Concerta, Ritalin and other drugs widely used to treat attention deficit hyperactivity disorder (ADHD) may lead to the possibility of hallucinations and suicidal tendencies in patients taking the drugs.
While such reports of serious psychiatric problems are rare and there is no proof they were caused by the drugs, the FDA has said a fuller discussion of the reports should be on drug labels. Current labeling discusses psychiatric problems that could be associated the drugs, but agency officials said they believe the labels do not clearly spell out the frequency and types of specific psychiatric problems.
The FDA made its decision to rewrite labels after reviewing 135 adverse event reports from Dec. 4, 2003, to Jan. 4, 2005, involving Johnson & Johnson's Concerta, a long-acting form of methylphenidate, the generic name for Ritalin, made by Novartis AG.
The Concerta review was mandated by law in drugs that are studied for use in children. Almost eight million prescriptions were written for Concerta during the same time period covered by the FDA review.
The FDA brought the review of Concerta to its pediatric advisory panel for advice on how best to communicate its concerns to the public. The agency chose not to focus on another category of ADHD drugs that includes Shire Pharmaceuticals PLC's Adderall, which was ordered off the market earlier this year in Canada after reports of 20 sudden deaths in patients, including 12 strokes.
The FDA has also been reviewing ADHD drugs for links to more serious problems like stroke. The drug labels warn of increased blood pressure and suggest the drugs can make any underlying psychiatric disorders worse, but patients may not be fully informed of the risks.
The most concerning serious side effects have been psychiatric events in young people. These have ranged from hallucinations, to suicidal thoughts, and even suicide attempts.
