My mom took One dose of advil pm and started having heart palpitations. She is 50 with no know heart problems, she says it gets worse when she lays down. She would like to know about how long this side effect will last and I want to know what are the warning signs if she should go to the hospital.
Hello! Thank you for asking oh Chat Doctor! I am glad to confirm you that Advil does not trigger any known arrhythmia facing current medical data as far. If your mom experience heart palpitations, probably this is caused by the primary disorder that generates pain, or something else. If palpitations persist and become disturbing, then you need to talk with your doctor (internist or cardiologist) for a comprehensive medical check up, to investigate her cardiac status, to identify any possible arrhythmia, or heart failure, or exclude any triggering factors, like anemia, thyroid dysfunction, etc. If Advil treatment aggravates those palpitations, then your mom should stop taking the Chat Doctor. Hope to have been helpful. Greetings!
