Over-the-counter stomach relief medication can alleviate occasional pain and discomfort. However, most medications aren't designed for everyday or long-term use. If you have a chronic issue, talk with your doctor to decide on a solution. To address occasional or acute stomach discomfort, always follow the instructions that come with your medication. A typical dosage may be: Daily for many long-lasting heartburn and acid indigestion medications and many laxative tablets. Every 30 minutes or hour for antidiarrheal medications. As needed for antacid chewable and gas relief capsules. In addition, many over-the-counter medications specify how long it's safe to take them. For example, you should take most antidiarrheal medications for no more than 2 days. You should take most fast-acting antacids for no more than a week at a time. Read the medication packaging carefully for more information. If you need relief and can't get out, let Instacart take care of the shopping for you and deliver your items the same day.
