I Was Recently Diagnosed With Wpw. I Am Having An

I was recently diagnosed with wpw. I am having an ablation in 2 weeks. I am taking a 100mg of flecainide daily. I have found it to make me a little sluggish. I also have been taking concerta xr for years for my ADHD. It has worked wonders for me. I take 40 mg daily. I wanted to know it I continued to take the concerta now would that interact poorly with the flecainide? I feel like I need it more now with the sluggish way I am feeling from the flecainide. Thanks in advance.
