this is a great question. but of course as a pharmacist i have to ask the patient a few questions too because we need to find out what is the root cause. could this be more of a virus running around and causing that nausea and vomiting because in that case it's really just flat coca-cola syrup over some ice and just letting it pass. if it becomes very violent though and they haven't been able to keep any food or water down you have to go in the emergency room because dehydration could cause more problems down the road. so you want to be really careful about that. if you are pregnant once again you can't really take the over-the-counter products that are available such as meclizine basically known as dramamine or also bonine. bonine is a chewable form of the product. these are not safe in pregnant women so therefore they have to go more the natural route. they could possibly try; there is a wristband that they could wear around their wrist to help prevent that as well. but if it's just for motion sickness because it was on a boat; which is very common for people or a train. the products that are available; dramamine and bonine are quite effective. they may cause a little bit of tiredness because they are actually antihistamines and by causing the drowsiness they are actually calming down the center in your brain that causes the nausea and vomiting. but once again as a pharmacist i am going to ask my patients a few questions first before i can help you find the right choice.
are there any over-the-counter solutions for nausea and vomiting?
