What medicines for travel sickness are available over the counter in India?

Besides the medicines mentioned above, Avomine is another medicine that you can buy. If you are traveling in a rural area or small town, the pharmacy employees may not understand English well. Ask for medicine to stop nausea and vomiting. In the local language, Tamil, ask for "Vaanthi nirkka maatthirai" (means tablets to stop vomiting).

Read my answer for Preventing sea sickness to get a list of nearly all brand names of sea sickness.

Getting seasick during car driving has some very specific causes:

• Do not break hard, do not accelerate hard. Because cars are very stable and cannot pitch/swing, it is the jerky movements triggering sea sickness. It can be also very bad road conditions, in this case drive slowly.

• Do not overtake if necessary, keep your distance to the car in front so you can anticipate the movement and adjust the speed slowly. Drive steadily and not too fast, especially in curves. Again to lower and avoid jerky motions. If you absolutely convinced that you drive steadily, put (when you are alone driving) a full glass of water (one thumb distance between water level and edge) between your legs as test. It will tell you if you are really a steady driver.

• Avoid any stressful environment. No honking, no cursing.

Your wife should do that:

• Sit in the front position alongside you, do not look sideways, do not read, do not look at her mobile. She should look to the front, keeping the horizon in her eye.

• Most important tell you when she feels that it begins: The sign is always that your mouth begin to water. Driving by car has the important advantage that you can stop on the road so that the seasickness cedes. If she is one of those wives who simply cannot open her mouth even if she begins to turn green, you need to watch her and decide when to pause. The important thing is that you should have enough time that pausing is no hassle. Once the body is able to acknowledge that it can escape seasickness by stopping, it is getting better to adapting because it can relax.
