Hello, my wife is 30 week pregnant, her reports shows everything to be normal, also doctor had told us earlier that baby growth is good but on last visit to doctor it was found that my wife had gained 2.5kgs in 15 days, so doctor suggested to take betnesol 12 mg 2 doses, as doctor suspects premature baby.. Kindly suggests its side effects and also will it have any health affects to mother or baby,
2) was it advisable to take this dosage based on the weight gain

Also want to know is 2.5kgs in 15 days is too high

Note: before pregnancy my wife was 49.x kgs
29th week- 61.8 kg and now in 30th week she is 64.4kg
BP: 70/122, age 28 years
