An Introduction to Dosing With MiraLAX

There is only one standard recommended dose for MiraLAX® (polyethylene glycol 3350). As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
 

MiraLAX Dosage for Constipation

The recommended dosage of MiraLAX for treating occasional constipation is 17 grams (about one heaping tablespoon) of powder dissolved in four to eight ounces of liquid and swallowed once a day.
 
Each MiraLAX single-dose packet contains 17 grams of powder. Therefore, if you are using the single-dose packets, dissolve an entire packet in four to eight ounces of liquid and drink it.
 
If you are using the multidose bottles, use the cap of the bottle to measure the correct amount of powder. Look for the dose line on the cap.
 
Although MiraLAX is not officially approved to treat constipation in children, it is sometimes used off-label for this reason. If your child's healthcare provider recommends this laxative, follow his or her specific dosing instructions.
 
The product information for MiraLAX states that this laxative should not be used for more than seven days. Although some people may need to use it for a longer period, it is a good idea to check with your healthcare provider before using the medicine long-term. If your healthcare provider recommends that you take MiraLAX for longer than seven days, you may disregard the label directions that warn against this.
