Myasthenia gravis is a disorder of the voluntary muscles in which the voluntary muscles get weakened and quickly exhausted. This happens as there is a loss of communication between muscles and nerves. Myasthenia gravis is an incurable disorder. However, symptoms can be managed with proper treatment.
Can You Take Magnesium With Myasthenia Gravis?
Magnesium sulphate is contraindicated in myasthenia gravis. This is because magnesium sulphate exerts an inhibitory effect on acetylcholine release. Acetylcholine is a chemical responsible for transmitting signals from the nerve endings to the muscle receptors. If this function is inhibited, it may worsen myasthenia gravis. Magnesium sulphate inhibits this function. Hence, it is contraindicated in myasthenia gravis.
Other medicines contraindicated in myasthenia gravis that are known to cause exacerbations of myasthenia gravis are-
Certain Antibiotics- Like fluoroquinolones, macrolides, tetracyclines, aminoglycosides, chloroquine etc.
Antidysrhythmic Drugs- Like calcium channel blockers, beta blockers, lidocaine, quinidine, trimethaphan, procainamide etc.
