Let's take a minute to talk about your medication.  

This is polyethylene glycol 3350, and this medication treats constipation. It normally produces a bowel movement in 1 to 3 days, and you should take it as directed by your doctor.  

It is helpful to know that you can use the bottle top as a dosing cup, which is marked with a line to measure a 17 gram dose. This dose also equals about 1 heaping tablespoonful. Then, you should dissolve it in a drink of your choice, like water, juice, soda, coffee or tea.  

At first, some side effects could occur, like stomach discomfort, diarrhea or gas. This is normal and should go away. But, if these or other side effects become reasons you want to stop taking it, please talk to your doctor or pharmacist.  

It is important to tell your doctor if you have unusual or bothersome stomach discomfort, diarrhea, nausea, or if you don't have a bowel movement in 3 days.  

For best results, you should follow your doctor's advice about eating fiber, drinking fluids and exercising to help you stay regular.
