For patients taking the tablet form of this medicine:

  • Swallow the tablets whole. Do not crush, chew, or suck the tablet.
  • Take with a full glass (8 ounces) of water.
  • If you have trouble swallowing the tablets or they seem to stick in your throat, check with your doctor at once. If this medicine is not completely swallowed and not properly dissolved, it can cause severe irritation.

For patients taking the liquid form of this medicine:

  • Dilute with a full glass (6 ounces) of water or juice and drink; follow with additional water, if desired.
  • Chill, but do not freeze, this medicine before taking it, for a better taste.

For patients taking the crystals form of this medicine:

  • Add the contents of one packet to at least 6 ounces of cool water or juice.
  • Stir well to make sure the crystals are completely dissolved.
  • Drink all the mixture to be sure you are taking the correct dose. Follow with additional water or juice, if desired.

Take each dose immediately after a meal or within 30 minutes after a meal or bedtime snack. This helps prevent the medicine from causing stomach pain or a laxative effect.

Drink at least a full glass (8 ounces) of water or other liquid (except milk) every hour during the day (about 3 quarts a day), unless otherwise directed by your doctor. This will increase the flow of urine and help prevent kidney stones.

Take this medicine only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. This is especially important if you are also taking a diuretic (water pill) or digitalis medicine for your heart.
