Hi Bhavanasree, Welcome to HealthcareMagic Forum.
What exactly are your other symptoms during this Pregnancy? Do you have Diabetes
or Hypertension? This Drug is not Prescribed in Pregnancy but it should be given only if the potential benefit justifies the potential risk to your fetus. I don't know what your Health Condition is right now. It is also prescribed if it is needed in a life threatening situation or for a serious disease for which safer drugs cannot be used or are if they are found to be ineffective. So, i would suggest you to take it as directed by your Doctor and go for regular follow up.
Good Luck and Wish you Good Health, Take Care.
