For pregnancy-related nausea, ginger can be a helpful option but it's not the recommended first line of treatment. There are other medications like Diclectin that are more studied and effective for this purpose. Pharmacists can prescribe these medications and some may be covered by insurance. If you decide to use ginger, the suggested dose is one 500mg tablet up to four times a day, if you are not taking any other medications. The regular Gravol (dimenhydrinate) is also safe during pregnancy, but Diclectin is usually the preferred treatment option. The usual dosage for Diclectin is 2 tablets at bedtime and 1 tablet in the morning and afternoon if needed. Feel free to reach out if you have any further questions.
