Pedialyte. This children's medicine contains electrolytes and other nutrients your body needs after a night of drinking. Pedialyte comes in powder packs, which can be mixed with water. The company also makes freezer pops as well as its standard liquid drink. To fight nausea, take small sips of the drink every 15 minutes. Adults can drink four to eight servings (32 to 64 ounces) throughout the day to maintain hydration. Use freezer pops as frequently as desired, but avoid going over 64 ounces in one day. Alka-Seltzer. Alka-Seltzer contains sodium bicarbonate (baking soda), anhydrous citric acid, and aspirin. The sodium bicarbonate helps neutralize stomach acid. Citric acid helps nausea by soothing the stomach. Adults can take two tablets every four hours without exceeding eight tablets in 24 hours. Pepto-Bismol. Pepto-Bismol is available in a liquid, chewable tablets, and caplets. Pepto-Bismol's active ingredient, bismuth subsalicylate, is believed to coat the stomach and stimulate intestinal walls to absorb electrolytes. Adults are advised to take one dose every 30 minutes as needed, not to go over eight doses in 24 hours. Nauzene. This over-the-counter chewable tablet contains sodium citrate dihydrate, which neutralizes excess acid in the stomach. Adults can take two to four tablets per dose, and can repeat doses every 15 minutes, without exceeding 24 tablets in a 24-hour period. Activated charcoal and carbon. There are several varieties of activated charcoal and carbon supplements that claim to cure hangover nausea by soaking up toxins in the stomach. However, such claims have not been scientifically studied, so there is a chance these supplements may not work. Note: These medications do not generally interact with the other drugs listed on this page, so it is relatively safe to follow a dose of one medication with a dose of another one after waiting the recommended amount of time between doses. However, it is always advisable to consult with a physician about any possible drug interactions.
