Can you use MiraLax after the expiration date? And how much to use for an adult single use?

Hi Dani,

I haven't come across any specific details pertaining to the safety of this medication after it's expiration date. However, I think it really depends on how long has it been since the product expired? If it hasn't been too long, it might still be functional enough to get the job done, but you're still probably better off getting a new batch if you want to play it safe.

Regarding dosing instructions, the usual adult dosing for Miralax is one cap full (approx. 17g) taken once daily or as needed. Apparently the measuring line on the bottle cap itself is supposed to be used as a guideline for taking a single dose (which also measures out to about 1 large tbsp).

Lastly, it is also recommended that you only take it for up to two weeks, since the active ingredient (Polyethylene Glycol 3350) can be habit forming.

You can learn more about this drug on the page for MiraLax Details

I hope this info helps to answer your questions!

I've been searching on the Internet for an answer to my question and came across this page. I give my cat Miralax and it works very well. I don't see an expiration date on the bottle I have but bought it almost a year ago I think. What is the shelf life? Also, it is supposed to be odorless (I though?), but it has now developed an odor (not bad) - should I assume it has expired? Thank you.

Hi,
I have quite a few bottles of polyethylene glycol 5330. I was wondering, they are still sealed tightly and stored well to the instructions. How many years after the expiration date can I still use them? I want to use them in my emergency supply stockpile. Well the little I've started with medical. I think it's a while. I've taken meds that were 4+ years over ex date and they worked fine.
Thanks
Tabi 55

Re: Rashida Abdul (# 8)

I think there's no problem you use it six months after expiration date.

Re: Wanda (# 13)

I have used Murilax or polyethylene glycol for more than 15 years, starting out on it 2 doses a day, now I take it once daily as needed. I have bottles that go back to 2016, 2017. I have been told that the medicine may become less potent, but I don’t notice anything different. I use it now every other day or as needed and I find it works better using it when I need it then taking on a daily basis. Also you can take an old bottle and mix it with a newer bottle, the only thing I notice is the older stuff sometimes doesn’t dissolve as good in water as newer stuff but so I have too stir longer is all. After 3 years it’s probably best to get some new stuff and mix it with your old.

Re: CH Lewis (# 14)

Instructions call for taking MiraLax for no more than 2 weeks. If you continue, your body will get dependent on it. Your call.
