DEAR DR. GOTT:
My daughter is in her mid-20s. She has developed (what I consider severe) motion sickness over the past 18 months. She gets carsick on anything other than a straight road. She takes no prescription medications, only guaifenesin daily since 2000. She has tried every over-the-counter medication, the seasick wrist bands, patches, and so forth. Nothing has worked for her.
DEAR READER:
Motion sickness may appear when the inner ear, eyes, and other areas of the body that sense movement send unexpected or conflicting messages to the brain, such as in a car when the eyes and inner ears sense motion but the body remains still. This leads to inappropriate stimulation of the ears, balance mechanisms and causes the individual to feel nauseated and/or dizzy often with vomiting. It is important to prevent symptoms because once started, it is very difficult to stop them.
Sudden onset of motion sickness is most likely due to an inner ear problem so I urge your daughter to see an ear-nose-and-throat specialist. He or she can test her for any abnormalities and provide treatment options.
While awaiting the appointment, your daughter may wish to try taking powdered ginger capsules. Many sufferers have had success in preventing motion sickness with these inexpensive pills found in most pharmacies and health food stores.
As an aside, I wonder if your daughter’s daily use of guaifenesin could be the culprit. This medication is an expectorant used to loosen phlegm and make coughs more productive. I have never heard of someone needing it on a daily basis. If she has excess mucus or a persistent cough, she needs to find out what is causing it. The ENT should also be able to assist her in this matter. ENDGOTT
