Congenital LQTS and Drugs to Avoid List
There are over 290 medicines on the Drugs to Avoid (DTA) list for patients with Congenital LQTS (CLQTS). Avoidance may not always be possible because many patients have conditions that require treatment with these drugs and safe alternatives are not available. Because there are at least 17 different genes associated with CLQTS, some patients may respond differently to these drugs and be safely treated with some of the drugs on the DTA list. Determining which patients can be prescribed these medicines requires special medical expertise and often involves close monitoring of the QT interval. The following information is provided to help patients, family members and healthcare providers to make these decisions and interpret the different categories of drugs on the DTA list.
