Dear sir Went through your post and I understand your concern, the Doctor is treating your patient for both both typhoid with ceftraxone and malaria with lariago, monosafe is safe in pregnancy and lariago belongs to category C which means it should be given when benefits overweigh the risk, your doctor must be of the opinion that the possibility of malaria is more than 50%in your patient and second 6months of pregnancy means the organs of your baby have already formed and lariago is less likely to cause any problem at this stage.
