How long does revolution stay good after opened

[Winnie77]

Hello I'm going to order a pack of the biggest cat dose revolution but I'm wondering how long after it's opened is it good if I put it in a small Amber glass bottle with cover . I figured I'd get the bigger size because the active ingredient is the same as the kitten one and only using one drop but I also don't want it to spoil .
Does anybody know how long it last once opened if stored good ?

As long as it covered and doesn't evaporate.
I've only bought the small tubes cat up to 15 pounds use only one drop.
After I open it I put plastic wrap or tape over it then put cap on. It's worked for me👍

So it comes in tiny tubes that have a lid that when pushed down on the top, pierces the top of the tube. Once you put your drop on your squirrel, you can replace the cap and push it down so the pin goes back into the hole you just pierced with it and does a good job of sealing it. Then, you need to keep that tube upright so it CAN'T leak. I use painters tape to tape mine to the inside of my refrigerator door. The additional tubes (the packs some with 3) are totally sealed and will stay that way until you pierce them to use. I would NOT try to transfer it to another container.

Good to know. So you keep opened ones in fridge, I've never done that. I'm guessing, does it keeps it stronger?

Wow thanks everyone and yeah I didn't even think prior to keep in the fridge makes sense would probably keep fresher longer.
Thank you everyone.
And I feel like a idiot I've been getting the kitten/puppy tubes all for 1 drop 🤦🏼*♀️
