Liquid Morphine still stable or not?

[maybunni]

I have a bottle of Ordine (Morphine Hydrochloride Trihydrate) that's been opened, it was prescribed to my mother around Feb 2024 (for her cancer which she passed from). There's around 160mL left of the 200mL bottle (2mg/ mL).

Although it's been unsealed, it's always been tightly screwed on and stored in a cool dark drawer.

Is that enough to do anything? I read that liquid morphine is not as stable as the pill alternative.

I also have a bottle of haloperidol tablets (0.5mg) but I read that that's a very low dose typically to treat nausea in older patients.

Any help would be appreciated! :)

that bottle have about 320 Mg morphine. (160*2=320)
The LD50 of morphine is approximately 42-60 mg/kg when administered intravenously. This means that a dose of 42-60 milligrams of morphine per kilogram of body weight is required to be fatal for 50% of the population.
320mg/60mg/kg=5Kg

so no, it will get you high but it wont kill you.
