There is no recommended time of day to take MiraLAX®. Begin taking MiraLAX® at the first signs of constipation and continue taking until you experience relief (up to seven days).
Adults and children ages 17 and older should take 17 grams of powder. Use the MiraLAX® bottle top to measure 17g by filling to the indicated line in the cap. Mix and dissolve into 4-8 ounces of any beverage (hot, cold or room temperature). For children ages 16 or under, ask a doctor. Single-dose packets of MiraLAX® are also available.
MiraLAX® generally produces a bowel movement in one to three days. Because it works naturally with the water in your body without causing harsh side effects, you do not need to worry about sudden urgency.
MiraLAX® does not cause harsh side effects such as gas, bloating, cramping or urgency, only gentle, predictable relief from constipation. When using this product, you may have loose, watery or more frequent stools.
MiraLAX® works with the water in your body to hydrate, soften and ease — unblocking your system naturally without harsh side effects. If you are taking a prescription drug, you should ask a doctor or pharmacist before use.
MiraLAX® is the same as Rx PEG 3350. Shortly after Nov. 2, 2018, you will no longer be able to purchase Rx PEG 3350, but MiraLAX® will continue to be available over the counter (OTC).
