Maybe tough, but : We order the following tests: anti-neuromuscular junctional antibody (and maybe anti-musk antibody), an EMG study using repetitive nerve stimulations to look for possible classical decriment patterns, cat scan of chest to see if there is large thymus, and perhaps a clinical tensilon test. That should for the most part confirm the diagnosis.
Dr. Howard Pomeranz

Myasthenia: An intravenous injection called a tensilon test, blood testing for acetylcholine receptor antibodies, and an electrophysiological test called an electromyelogram can all be used to help make a diagnosis of myasthenia.

Nerve disease: In patients with myasthenia, the acetylcholine receptor that helps form the neuromuscular junction is destroyed by the immune system. This causes nerves to be unable to trigger muscle contraction, leading to fatigable weakness. In demyelinationg disease, the myelin insulation surrounding the nerve is attacked by the immune system, disrupting signal transmission.

Two ways: Some medications are designed to enhance the neuromuscular junction connection, and prolong presence of acetylcholine. Since myasthenia is an autoimmune disorder, steroids and other immune agents can address the underlying causation.

Comments: The best documented problems occur with many but not all -mycin antibiotics, and may be best to avoid Cipro, (ciprofloxacin) Ketek, Z-pak, but also most fluoroquinolones. Stay away from Botox, Quinine, and all beta-blockers.
