What antibiotics are safe in patients with congenital LQTS?
Because these drugs are not tested in LQTS patients and because there are multiple forms of LQTS, it is not possible to say that any antibiotic is “absolutely safe”. There are some that clearly have been found to be dangerous and we include them on the CLQTS List. However, even if a drug is not on this list, you cannot assume that it will be safe. Use caution when administering any medication to patients with LQTS.
