Why aminoglycosides are contraindicated in myasthenia gravis?
Aminoglycosides should be avoided in patients with myasthenia gravis because of the risk of prolonged neuromuscular blockade.
What causes weakness in myasthenia gravis?
In myasthenia gravis, your immune system produces antibodies that block or destroy many of your muscles’ receptor sites for a neurotransmitter called acetylcholine (as-uh-teel-KOH-leen). With fewer receptor sites available, your muscles receive fewer nerve signals, resulting in weakness.
Why antibiotics exacerbate myasthenia gravis?
Most antibiotics that have been identified as harmful to patients with MG interfere with neuromuscular transmission. In normal neuromuscular transmission, acetylcholine is released into the neuromuscular junction after a nerve impulse is sent from the brain.
What antibiotics are bad for myasthenia gravis?
Medications that Can Worsen MG Weakness
- Aminoglycosides (amikacin, gentamicin, kanamycin, neomycin, streptomycin, tobramycin)
- Tobramycin – probably the weakest neuromuscular blocking effect (least problematic)
- Macrolies (erythromycin, zithromycin or z-pack) – use cautiously, if at all.
What vitamins are good for myasthenia gravis?
Vitamin D could be a potential therapy for some disorders. This case report shows the correlation between vitamin D and myasthenia gravis clinical status, which reinforces the possibility of benefits with massive-doses of vitamin D in MG.
What is the drug of choice for myasthenia gravis?
Rituximab (Rituxan) and the more recently approved eculizumab (Soliris) are intravenous medications for myasthenia gravis. These drugs are usually used for people who don’t respond to other treatments. They can have serious side effects.
What happens if you take aminoglycosides with myasthenia gravis?
Aggravates muscle weakness. Aminoglycosides have been associated with death when used in patients with a history of myasthenia gravis. Exacerbations of the symptoms of myasthenia gravis and new onset of myasthenia gravis have been reported.
Are there antibiotics that aggravate myasthenia gravis?
Our results indicated that aminoglycoside antibiotics could aggravate the symptom of myasthenia gravis.
Can you take sulphoncosides with myasthenia gravis?
In addition, aminoglycosides are contraindicated by the manufacturers in MG patients so usage should be on specialist advice only. Sulphonamides have a depressant effect on neuromuscular junction and may increase weakness. Fluoroquinolones should be avoided in patients with a history of myasthenia gravis.
What kind of weakness does myasthenia gravis cause?
Myasthenia gravis (MG) is an autoimmune condition that affects neuromuscular transmission leading to muscle weakness, muscle fatigue and general weakness.

Can a statin cause myasthenia gravis muscle weakness?
Some authors suggest these symptoms could be due to several potential mechanisms, including underlying myasthenia gravis aggravated by the muscle toxicity of statins or antibody-mediated myasthenia gravis induced by statins. Statins can be used in patients with myasthenia gravis with counseling on potential worsening of muscle weakness.
Where does the name myasthenia gravis come from?
Myasthenia gravis is a chronic autoimmune neuromuscular disease that causes weakness in the skeletal muscles, which are responsible for breathing and moving parts of the body, including the arms and legs. The name myasthenia gravis, which is Latin and Greek in origin, means “grave, or serious, muscle weakness.”.
