<s>[INST] Hi i am over 33 weeks pregnant and my partner has malignant hyperpyrexia as does all his family ( mum/ dad ect) there is a high risk that the baby will probably have this aswell, I am wondering if it is safe to take senokot while there is a risk of the baby having malignant hyperpyrexia. Hight 5.4 dont know weight..i have no health problems and not taking any medication. [/INST] Hi,   Thanks for the query. I understand your concern.    Malignant hyper pyrexia is genetic disease.. which may or may not exhibit in your fetus.. In case one wants to ascertain it before child birth,/ after birth chromosomal analysis is the answer    The condition is triggered with the drugs used before/  neuromuscular  blocking agents/ volatile  anesthetic agent.      Senokot is a  drastic purgative .. and is not advocated in pregnancy. You should take stool softener like cremafine instead.    Thanks.. </s>
