Take by mouth usually once daily, or as directed by your doctor or the directions on the product package.
If you are prescribed the individual packets, mix the powder as directed by your doctor or pharmacist. If you are using the bulk bottle, use the provided cap to measure the prescribed dose. Mix the powder with a glass (4-8 ounces/120-240 milliliters) of liquid such as water, juice, soda, coffee, or tea. Before drinking the solution, stir the powder well until it completely dissolves. If you have any questions, ask your pharmacist.
