Uses of Myestin Tablet

Benefits of Myestin Tablet

In Treatment of Myasthenia gravis

Myasthenia gravis is a neuromuscular disorder that leads to weakness of muscles that are under our control, such as those of the eyes, face, and swallowing. It can result in double vision, drooping eyelids, trouble talking, and trouble walking. It happens due to impaired coordination between muscles and nerves. Myestin 30mg Tablet makes this coordination between nerves and muscles better and relieves the symptoms. As a result, your muscle strength is improved and you are able to lead a better life.

In Treatment of Paralytic ileus

Paralytic ileus is the obstruction of the intestines due to improper functioning of the nerves and muscles in the intestine that impairs digestive movement. Myestin 30mg Tablet induces contractions in the intestinal muscles and improves their function. As a result, there is better movement of food and this treats the obstruction. Take it as advised by the doctor and follow your doctor’s instructions carefully.

In Treatment of Post-operative urinary retention

After an operation, there may be problems in emptying the bladder. This may be due to disturbed coordination of nerves and muscles of the bladder. Myestin 30mg Tablet helps to improve this problem and treats post-operative urinary retention effectively.
