Invirase (saquinavir): Label Change – Risk of Abnormal Heart Rhythm
October 21, 2010 – The FDA notified healthcare professionals of new risk information added to the Warnings and Precautions section of the antiviral drug Invirase (saquinavir), describing a potential change in the electrical activity of the heart when Invirase is used with another antiviral medication, Norvir (ritonavir). Changes in the electrical activity of the heart may lead to abnormal heart rhythms, known as prolonged QT or PR intervals. A prolonged QT interval can lead to a serious abnormal rhythm called torsades de pointes, which can be fatal. A prolonged PR interval can lead to a serious abnormal rhythm called complete heart block. Torsades de pointes and complete heart block have been reported in patients taking Invirase with Norvir.
What are Invirase / Norvir used to Treat?
The medications Invirase and Norvir are given together to treat HIV infection. Norvir must be given at a low dose with Invirase in order to increase the level of Invirase in the body. In February 2010, FDA announced it was reviewing clinical trial data about a potentially serious effect on the heart from the use of Invirase in combination with Norvir.
