Motion Sickness Fixes: Consumer Reports' ShopSmart

First, try these: GINGER AND WRISTBANDS Although far from proven, these are safe and worth a shot, especially for mild symptoms. Ginger root, typically sold in candies and capsules, has the most supporting evidence. Occasional use of up to 250 milligrams four times a day is considered safe for most people, including women who might be pregnant. Bracelets such as Sea-Bands, found at drugstores, stimulate acupressure points on the wrist and have been shown to combat nausea in some situations. The evidence that they work against motion sickness is mixed. However, they're safe and can be used along with other remedies.

Next, try this: ANTIHISTAMINES Older over-the-counter antihistamines such as dimenhydrinate (Dramamine) and diphenhydramine (Benadryl) have been proven to counteract motion sickness and are approved by the Food and Drug Administration for use by children older than 2. The catch is that they take 30 minutes to an hour to kick in, and they can leave you feeling drowsy or light-headed. Newer, non-sedating over-the-counter antihistamines such as loratadine (Claritin) and cetirizine (Zyrtec p) might relieve allergy symptoms but don't appear to quell a queasy stomach.

If all else fails, try: PRESCRIPTION DRUGS Promethazine (Phenergan) is another antihistamine effective at relieving nausea, but it might make you sleepy. Another choice is prescription strength meclizine (Antivert), although it, too, may cause drowsiness. A scopolamine patch (Transderm-Scop) is also very effective, but side effects including blurred vision and severe drowsiness make it a treatment of last resort. Some patients also report a rebound effect, including nausea, dizziness, and headaches when they remove the patch.

How to nip that queasy feeling in the bud:

Eat stomach-soothing foods. Have a light meal about 3 hours before setting out. Avoid dairy products and foods that are high in protein or sodium. A light breakfast of an orange, for example, may stay down better than bacon and eggs. If motion sickness strikes, munch on crackers and take small sips of a carbonated drink or fruit juice. Chew on ginger candies or pop a ginger supplement. Chamomile and peppermint are also used to quell stomach upset.
