How long does Ovex threadworm stuff keep for?

[FlyMeToDunoon]

The bottle has been opened. I haven't got the leaflet and the box doesn't say. We have had it for a few months now and may need to use it again.Has anyone gor the leaflet to look and see if it says.
I can just buy more but would like to use this up if poss.

It will have a use-by or best-before date on it somewhere - does the bottle have a printed label?

It has a use by but does not specify how long it will keep after opening.

ahhh, I getcha, sorry.

Shelf life is 5 years & it doesn't appear to say refrigerate after opening?

I've used old Ovex after a few months. We have it sent here in 5 litre drums

So ok to use do you reckon?

link to the leaflet here - it just says

"Storing this medicine
Keep the product out of the reach and sight of children.
Do not use your medicine after the date shown as expiry date on the
packaging."

HTH

Thank you so much. I am going to use it!
