My k level is 3.2. i have been really constipated and have taken miralax (polyethylene glycol) for 2 days and colace for 3 days. can i take 200mg of colace today (the 4th day) or is my k level too low to be taking these laxatives?

Other options: If your potassium is low, your magnesium might be low as well. Try a magnesium supplement of about 200-250 mg once or twice day and make sure you are drinking a lot of water with the Colace (docusate sodium) since it works by holding water in the stool. Another supplement that can be helpful for constipation is Vitamin C 1000 mg once to three times per day. If you start getting diarrhea, decrease your doses.

K: You can take colase but go ahead and take some K also

Laxatives & low K: you can lose potassium if you have diarrhea but it's ok to take 2 colace (docusate sodium) per day for constipation. You can also try senna or Metamucil or citrucil to increase fiber and help constipation. You can also eat leafy green veggies and drink OJ and eat bananas to raise your potassium

K level constipate: Your k level low but if you eat 3-4 bananas you can bring it up. Also pedialyte. What may help with your consitpation is hydration, drink about 3 -3.5 liters of fluid water /gatorade a day just water will decrease sodium eat high fiber, avocados, cup of oats, cup of lentils, brown rice, barley strawberries, kale.
