Hi Murat,
I am following up on another question you asked here as I cannot find the original question.

You asked if there are blackbox or warnings relative medicines that are not advisable to take with MG. The answer is yes. Some infusion medicines require carrying a note card from the pharmaceutical company to advise what to look for in case the medication is causing an adverse reaction. Below is a basic summary. Note that there is cautionary warning- some meds listed below can be taken as your doctor may see more benefit than harm. THE KEY IS TO BE IN COMMUNICATION WITH YOUR NEUROLOGIST IF YOU ARE ASKED TO ADD MEW MEDICATIONS. YOUR DOCTORS CAN CONVERSE TO ENSURE YOUR SAFETY TAKING MEDICATIONS. (Information sourced through Google AI and is consistent with what my Neurologist gave me, but in a reduced form for easier understanding.)

Medications that are bad for myasthenia gravis (MG) include certain antibiotics, beta-blockers, calcium channel blockers, muscle relaxants, and Botox because they interfere with neuromuscular transmission. Additionally, immune checkpoint inhibitors and statins can induce or worsen MG by triggering autoimmune reactions. It is crucial to consult with a doctor before starting any new medication, even over-the-counter drugs, to avoid complications.
Medications to Avoid or Use with Caution

Antibiotics:
Aminoglycosides (like gentamicin), quinolones (like ciprofloxacin), and macrolides (like azithromycin) can worsen MG symptoms and should be avoided when possible.

Beta-blockers:
Drugs like propranolol and metoprolol, often used for heart conditions, can interfere with neuromuscular function.

Calcium Channel Blockers:
Verapamil and diltiazem can negatively impact the neuromuscular junction and should be used with caution.

Immune-Related Drugs:
Immune checkpoint inhibitors (ICIs): Used to treat cancer, these drugs (such as nivolumab, pembrolizumab, and ipilimumab) can induce myasthenia gravis.

Statins: These cholesterol-lowering drugs have also been associated with causing or worsening MG.

Botulinum toxin (Botox):
Can worsen or unmask MG symptoms by targeting the same neuromuscular structures.

Magnesium:
Can interfere with neuromuscular transmission and may exacerbate MG.

What to Do if You Have MG
Always consult your doctor:
Before taking any new medication, including over-the-counter drugs, speak with your primary MG doctor to check for potential interactions.
Inform your doctor of all medications:
Be sure your care team is aware of all the medications you are currently taking.

It can be very difficult pursuing disability. It is very worthwhile to speak to an attorney to help go through it. You need to have a lot of detailed documentation of diagnoses spanning specialists, lab tests, imaging results, and a medical team willing to support you as you go through the process. You also need to supply your work history documentation as well. The sum of this type of information.goes into the evaluation of anyone's case.

And as Johanna notes, it's best not to go through the process alone because of the associated stress related to the application process.

I never received any.
However I've read that so many people with it had to fight for years before they received it
I finally just retired early and my stress has been less.
Stay hopeful 😎 and allow someone to help you through the process because the stress is real.
