Which blood pressure and heart rhythm medications should be avoided or used with caution when you have myasthenia gravis? Great question — and an important one!

Several types of these medications can worsen MG symptoms, so it's worth knowing what to watch out for. Calcium Channel Blockers

Some calcium channel blockers have been linked to worsening MG symptoms, including:

- Felodipine
- Nifedipine (Procardia)
- Verapamil (Verelan)

People with severe MG who took nifedipine or verapamil were more likely to experience breathing difficulties. The good news is that most people recover once they stop taking these medications. Beta-Blockers

Beta-blockers like propranolol (Inderal) have been reported to temporarily worsen MG symptoms, though symptoms often improve over time. Heart Rhythm Medications (Anti-Arrhythmics)

Certain class 1a anti-arrhythmic drugs can also worsen MG symptoms, including:

- Quinidine
- Disopyramide
- Procainamide
- Lidocaine (systemic)
- Mexiletine
- Flecainide
- Propafenone

Always make sure every healthcare provider and your pharmacist knows about your MG diagnosis before starting any new medication. Working closely with your care team is the best way to find safe options for managing your heart health.
