Yes, all medications expire, but that does not mean they become dangerous, they just start to lose efficacy. Overall, the FDA advises that you dispose of them and see your doctor, if you need a new supply. This medication carries the risk of being habit forming and may cause side effects, such as nausea, dizziness, headache, constipation, and dry mouth.

Is there anything else I can help with?

I get 27 bottles to go at my clinic, all dispensed on the same date. They are effective beyond the last day I'm supposed to take them. Mine all last for the entire 27 day period (& beyond). The only time my methadone has lost it's potency is in 95°F or hotter weather.

I have been prescribed (liquid) methadone for about 4 years now and im on 140mgs. I get 13 take homes every 2 weeks and they print the expiration date the bottles and all of them say they expire after about 6 months. Ive found old bottles of mine before tho that were almost 2 years old and they seem to work fine even tho i do believe the potency is noticeably lower after that amount of time but i had a Dr. tell me once that if bottles are stored in a fridge they can last longer then the 6 months printed on the bottles.

I just recently kicked my methadone at 6mg, and have just been taking kratom. But after about 3 weeks I’m really starting to feel it if I don’t have the kratom. I had a few old bottles that had been stored in my fridge for the time being (close to a month) but the other day the restless arms and legs and lack of being able to sleep for more then 3 hours a night pushed me too take my gfs dose which was about 2mg(she had bottles in fridge left over too) But after taking it my girlfriend went to take one as well and noticed after she shook the bottle there was what looked like black mold floating around inside after she shook it up. Any ideas? Cuz I Definetly drank it??

That’s crazy cuz my bottles I get say a year from the date the liquid was dispensed. I have an old bottle full and it’s for emergencies but it’s got like darker red in the middle and it looks like how I put oil in water it’s in the middle. It’s super strong the Tast.

Yes its fine to take so long as you normally take that much. If you haven’t taken it in the last 3-4 days it could cause overdose

I have a question, when I was on a higher dose I saves a bottle of Methadone for emergencies. Today is one of those days as I missed, can I still drink the bottle that’s been in my safe for now a year? No mold or weirdness and has always been sealed back since I took the half out.

Hi. I’ve took methadone for decades now and I can say I've gone two weeks away at a time and it’s fine..and I saved up two to five mil a day and every week I’d add to the last doses till I had a week spare. I stored in a dark cupboard and six months to a year later I could use it. It didn’t taste different and it worked exactly the same so as long as it’s in a dark place... not a fridge, don’t put it in the fridge as it weakens it by ten percent I’m told, however if you store in a tight lid bottle it should be fine. However if it has anything in it or the color changes don’t take it as it is off. Usually it is green and I had stored 200ml for over two years an went to check one day and it went light brown. I discarded it down the drain. Don’t chance it if it is diff in anyway, but 24 months in a sealed bottle is fine...but an open bottle is three months and that’s factual guaranteed by GP…but guys gals ladies gents please take care and if you nap and wake sweating you're not on the proper dose. You need to up it or detox. I’d take the detox. Also do not use Imodium for diarrhea as that’s a poor man’s detox!! In the old days hippies would take them bowel pills for withdrawals and I hear it helped but so dodgy to do so don’t take them period, keep trying to get clean people as lot of the addiction is in the head...honestly when it’s fight or flight you conquer it. I must also say recovery is the new cool. You're all winners. Respect.
