I was on Zofran for 2 months while pregnant with my 2nd son as I had "morning sickness" so badly that I couldn’t keep anything down & instead of chancing a hospital admittance for dehydration, my OB prescribes this -I couldn’t believe it when I found out it was $800/month! Luckily I paid only our $30 co-pay.  I didn’t realize it was also used in these instances. Interesting.
