I was also prescribed with this which is currently out of stock in NUH. I didn’t take it yet as I hope to reduce the amount of medication I am taking. Instead, I am using the nausea relief sea band which is effective to me. It tackles on your nei Kuan point on your wrist to help reduce morning sickness and GERD. You can try if you want.
Same was prescribed at 7.5 weeks, i try to cut down on medicine taken and used once in the morning when I felt I couldn't keep my breakfast down. Didn't feel side effects, it helped to reduce my urge to puke. 😃
