Myasthenia Gravis and Cardiovascular Medication

Myasthenia gravis may pose a risk to patients using cardiovascular medications to treat heart conditions (coronary artery disease, hypertension, high cholesterol, and heart arrhythmias). Beta-blockers, calcium channel blockers, and statins should be used cautiously. Lidocaine (Xylocaine), Procainamide, and Quinidine are some drugs known to have caused adverse reactions with MG.

Do you have Myasthenia gravis and are on or have been on cardiovascular medications? Which ones and what dose? Did you notice any triggered symptoms?

How long has this persisted if you had no problem using cardiovascular medications?

  1. I take meta topical for rapid heart rate. My weakness is getting increasingly worse. If I don't take the topral my heart rate shoots up to 130,140 or higher
    Anyone have any suggestions for another medicine that would decrease heart rate? Thanks so much.

    1. sorry to hear you are experiencing increased weakness. Have you had an opportunity to speak with your physician about what you are experiencing and getting their opinion on what may be helpful? If you haven't reached out to them already, I would encourage you to do so. Wishing you well. Kindly, Jessica (Team Member)

    1. Jodi, thanks for ur concern. I actually texted my cardiologist totally and am waiting to hear. In answer to a question someone else asked, no.i do no feel my myasthenia is being controlled well. I would love another dr or onion but my options are limited. Love this group. It helps so much.

  3. I started taking a statin last year and just following I began to have excessive nose bleeds. They were so bad, I thought I may need to be hospitalized. I just read about staying away from stations. I think I am going to stop taking it altogether.

    1. that sounds terrible, I’m sorry you had that experience! If you haven’t already, I would encourage you to reach out to your doctor with your concerns about the statins. Sending well wishes, Julie (team member)
