Can I take Flecainide and Wegovy flextouch together?

Why this happens

Wegovy is a GLP-1 receptor agonist that delays gastric emptying (the time it takes for food and pills to leave the stomach). This can delay or alter the absorption of oral medications like flecainide. Furthermore, semaglutide can sometimes increase resting heart rate, which may interact with the heart rhythm effects of flecainide.

What you should do

You should speak to your doctor before using these together. Because flecainide has a 'narrow therapeutic index' (meaning the difference between a safe dose and a dangerous dose is small), your doctor may want to monitor your blood levels or perform an ECG (heart trace) more frequently when you start or change your dose of Wegovy. Contact your doctor immediately if you feel dizzy, faint, or notice a change in your heartbeat.
