how long can I keep this once it has been opened ?

According to the manufacturer's website, it can be kept until the expiry date on the tube so this is a useful product to keep handy in case of sudden need. It worked like magic on my cat, diarrhea cleared up after only 3 doses. Could not administer it as directed as my cat is a difficult little madam, so disguised in a teaspoonful of tinned sardine!!

Unopened, how long can I keep this in the cupboard?

it says on pack even when opened can be used up untill best before date and on my pack thats 18 months away .so people saying should be used within a month of being opened may well be ill informed.

I'm using this for cats. does the 60ML have 1/2ml markers? and once open how long will it last?

No has 1ml markers. But you could squeeze out 1ml on to saucer then 1/2 it, cover and use remainder next day. As the tube is enclosed we have used up to one year. We have a dog with sensitive tummy and use much less than recommended dose-we find this does the trick. Hope this is useful info for you.

how long should you use this

My vet used to tell me to use the pack up to promote good gut health it’s not just to firm up stools it’s a healthy bacteria for the gut
