I started taking 50mg Flecainide twice a day 5 weeks ago, no Afib episode so far. However, I sometimes feel a sensation of chest tightness as if wearing a sports bra that are too tight on me. Should I be concerned? Anyone feel the same? thanks!
Drugs.com lists it as a not uncommon side effect. I would mention it to the doctor who prescribed it, but unless it comes with other symptoms it's probably nothing to worry about.
