Try original GRAVOL^TM Comfort-Shaped Suppositories with dimenhydrinate, which are available in two dosage strengths – for 100 mg for Adults and 25 mg for Children ages 2+. GRAVOL^TM Suppositories with dimenhydrinate are easy to use. Remove the foil or plastic from the suppository. For easier insertion and greater comfort, moisten, and smooth any edges on the suppository before using. Insert a half or whole suppository every 8 or 12 hours, or as recommended by your physician. To divide a suppository into two equal parts, remove it from the foil and use a knife with a sharp blade to cut through the suppository.
