Remember, however, that every drug has potential side effects. Taking any medication -- even if it's available over the counter -- can have serious repercussions, particularly for children, pregnant women, or individuals with allergies, medication conflicts and other contraindications. Consult your doctor before starting any new course of medication.
The following is a roundup of the most common travel maladies, along with suggested remedies for each. We've also included a collection of tips and resources for keeping yourself healthy on the road.
Deep Vein Thrombosis
Deep vein thrombosis (DVT) is a serious and potentially fatal condition in which blood clots develop in the leg. Despite its long-time nickname, "economy class syndrome," it's common on long-haul flights in any class of service in which movement is restricted. (Recent research suggests that travelers who prefer the window seat may be more susceptible, since they're less likely to get out of their seat.) The best strategy to prevent it is to stand up, stretch and walk around the plane as often as possible.
Those who have a history of certain medical conditions (such as previous blood clots, active cancer or estrogen use -- including birth control pills) may be at greater risk for economy-class syndrome; these folks might want to consider using aspirin, whose blood-thinning capacities make it a good antidote. Be sure to consult your doctor.
Five Foods to Avoid Before Flying
Motion sickness is a complex condition, more a jumbling of the senses than a medical condition as we usually think of it. Motion sickness is caused by irregular and abnormal motion that disturbs the organs of balance located in the inner ear, as well as discordant signals from your eyes and balance mechanisms. As these get more out of concert, nausea, dizziness, headaches and cold perspiration set in.
Dramamine (dimenhydrinate) and Bonine (meclizine) are two of the most common motion sickness remedies.
Transderm Scop (scopolamine) is a small circular patch you stick behind your ear to reduce the nerve activity in the inner ear, thereby reducing motion sickness.
Many people have also found Sea-Bands and similar products to be helpful. They work by stimulating acupressure points on the wrists that are believed to control motion sickness.
I haven't tried this, but ginger apparently has motion sickness applications. Look for capsules at your herbal store, generally in doses of 500 - 700 milligrams. Ginger also affects blood clotting, so travelers using blood thinners or those who suffer from hemophilia should avoid taking ginger without consulting a doctor.
Sleeping on a plane is a true challenge -- cabin noise rivals that of concerts, seats are cramped and hard, and there are constant interruptions. Many travelers turn to medications to help them sleep away hours spent in flight. With any sleep aid, it's a good idea to try it out at home before you leave to see how your body will react.
Many travelers swear by Ambien (zolpidem), which has considerable sleep-inducing power but doesn't leave you feeling groggy upon arrival. It is also considered to be less addictive than benzodiazepine drugs (such as Valium and Xanax, two other common options). I tested Ambien for the first time on a recent 10-hour flight and packed in seven hours of sleep that felt very natural, not the groggy, heavy-lidded sleep that occurs with something like Dramamine, the only other drug I've ever taken in flight.
Bonine (meclizine) and Dramamine (dimenhydrinate) are motion sickness medications that also double admirably as sleep aids.
Antihistamines like Sominex and Benadryl contain diphenhydramine HCl, which can cause drowsiness.
Traveling While Contagious: Should You Do It?
Melatonin is not a sleeping pill per se, but a hormone that occurs naturally in the body, and is secreted as light fades at the end of the day. Rather than acting like a sedative, putting us under and keeping us there, it acts more like a sleep trigger, controlling when we go to sleep and when we wake up. Melatonin effectively acts as your body's time clock. (For example, as we age, melatonin levels in our systems decrease; that's why our grandparents always seem to be up all night!)
According to proponents, a well-timed dose of melatonin can put you under, and if your sleep habits are strong, you should stay under. Melatonin can also help considerably in conquering jet lag.
Note that melatonin is not presently regulated by the FDA, and its effectiveness has not been clinically proven. Appropriate dosage is not entirely clear, and purity can vary among products.
The aforementioned melatonin has also gained popularity as a cure for jet lag. Another remedy that got a lot of buzz a few years back is Co-E1 NADH (previously known as Enada NADH), an over-the-counter vitamin B supplement. Co-E1 NADH has been credited with everything from curing jet lag to increasing memory and test scores. On an edition of "20/20," one testing subject said, "I feel great. I feel wonderful. I feel alert." (At least she didn't start singing "I feel pretty...")
