How should I take anti-diarrheal or anti-gas medications?

Pay attention to the directions on the anti-diarrheal or anti-gas medication package. If you take the anti-diarrheal drug called bismuth subsalicylate (sold as Pepto-Bismol and Kaopectate) as a liquid, measure your dose carefully with a proper measuring spoon, not a kitchen spoon. Or if you are taking a chewable tablet, chew before swallowing it.

For loperamide, another anti-diarrheal medication sold as Imodium, take it with a glass of water. Do not take loperamide more than three times in 24 hours unless your doctor approves it. Imodium A-D Liquid and New Imodium A-D Liquid contain two different strengths of loperamide.

If you switch from using one brand to the other, follow the dosing instructions carefully.

For treating excess gas, simethicone (in Alka-Seltzer Anti-Gas, Gas-X, Maalox Anti-Gas Extra Strength and Mylanta Gas) works best if you take it after a meal or right before you go to bed. Read medication directions carefully. In general, drink plenty of water to prevent dehydration from diarrhea.
