User Feedback


Q. Does Myestin cure myasthenia gravis? For how long do I need to take it?

Myestin helps reduce and improve muscle weakness and hence relieves the symptoms of myasthenia gravis but does not cure it. The length of time for which you have to take Myestin will depend on your needs. You should not stop taking Myestin until and unless advised by your doctor, even if you start feeling better.

Q. Will Myestin have any effect on my baby if I am breastfeeding?

A very small quantity of Myestin passes into breast milk, which may or may not affect your baby. Ask your doctor if you can continue to breastfeed your baby.

Q. Can I take Myestin for constipation?

No, Myestin should not be taken for any type of constipation. It is used only when constipation occurs due to paralysis of the intestine and strictly on prescription by the doctor.

Q. Who should not take Myestin?

Myestin should not be taken by patients who are allergic to it. It should also be avoided by patients who are constipated or cannot urinate, unless the doctor has advised to use this medicine. This is because Myestin is only used to treat certain types of constipation and inability to pass urine.

Q. What should I do if I have accidentally taken more than the required dose?

You should immediately seek help at a nearby hospital or contact your doctor urgently. An excess dose of Myestin may cause stomach pain, nausea, vomiting, diarrhea, excessive sweating, salivation, blurred vision, excessive weakness, difficulty in breathing and even paralysis.
