To relieve dry mouth, suck on (sugarless) hard candy or ice chips, chew (sugarless) gum, drink water, or use a saliva substitute. Just before taking, mix the drug with half a glass (4 ounces or 120 milliliters) of water or milk, or orange, grapefruit, tomato, prune or pineapple juice, and drink all of the mixture. Do not drive, use machinery, or do anything that needs alertness or clear vision until you can do it safely.
