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??
