OTC Remedies for Morning Sickness
No Rx Needed
My niece, let's call her Kelly, has been having so much nausea and vomitting with her first months of pregnancy that she lost 9 pounds. She should be gaining, not losing.
I consulted the Journal of Midwifery and Women's Health for suggestions to help Kelly. It seems that ginger, 125 to 250mg four times a day, or one cup of pre-packaged ginger tea four times a day can help. This dose was safe in small studies. Larger studies are needed to conclude that ginger is 100% safe for the fetus.
The antihistamines diphenhydramine (Benedryl) and doxylamine (Unisom) are effective and proven safe. The downside is the well-known side effect of drowsiness. Kelly can take these if she has a day off and doesn't need to drive.
Vitamin B6 (pyridoxine) helps the nausea more than the vomitting. The best dose is not known. One possible dose to try is 25mg three times per day. Like ginger, this dose was safe in small studies, but larger studies are needed to make sure there is not a small risk of harm to the fetus.
Consult your doctor for risks and benefits of these treatments specific to your situation.
