Dear mam, As you are anemic right now it is adviced to increase your hemoglobin level upto 12 before conception.
1) Tab.Livogen 1-0-1 for one month
2) Diet: Greens, Dates, Jaggery instead of
sugar,
Fruits, Egg white, Meat
As far as dexorange tablet is concerned it is a requirement to take folic acid 0.4 mg daily from one month before conception. So its not only safe to take Dexorange but mandatory to take.And as your age is 36 it is adviceable to consult an Obstetrician before planning the pregnancy and discuss about any possible complications and ways to prevent them. Hope this helps. Regards.
