The last time i took zofran (ondansetron) i got lockjaw, are there any safe alternatives?

Yes: Yes, vitamin B6 25-50 mg 2 to 3 times per day helps morning sickness. Ginger has also been found to be helpful. There is a point 3 fingers breath above the inner union of the hand connecting to the arm moving towards the elbow, if rubbed deeply (acupressure), will relieve nausea and vomiting.

Dramamine (dimenhydrinate): If you are experiencing nausea there are several options you can talk to your doctor about. An over the counter alternative is dramamine (dimenhydrinate).
