It is known that many people with Rett syndrome have a prolonged QT interval – a heart condition that can lead to a severe or even lethal arrythmia. Therefore, they should be periodically observed by cardiologist and in case a long QT would be diagnosed, they should follow the prescribed treatment and avoid taking drugs that might prolong QT interval even more or impose a higher risk of cardiac arrhythmias. Among such potentially dangerous drugs are some widely used anti-reflux drugs, antibiotics, antiepileptics, antidepressants and many more.
How to know which drugs are safe to use?
You should always check any drug in the QT drug list, that is managed by CredibleMeds.
Every year new drugs are added to this list as more information is gained about their side effects. Thus, it is very important to check the newest version of the QT drug list. If you are searching for a drug in a PDF file or a printed document, always check the date at the bottom of the last page. Search for a newer version of the document if yours is more than half a year old.
Due to frequent changes of the QT drug list, we strongly recommend one of the following options to get the up to date information:
- You can find the full and newest QT drug list on the website of CredibleMeds, but it will require a simple and free user registration.
- You can also download a free CredibleMeds app for your smartphone (IOS, Android and Windows) which will allow you to check any drug even faster. It is especially convenient during your visits to a doctor as just in a few seconds you can check if the drug is in the QT drug list or not, as well as the type of the risk it may impose.
In case you don’t have any of the two recommended options at hand and need to check the list urgently, you can find a PDF file here:
