I accidentally dropped my Estrofem tablet rotating dial container and the plastic tab piece broke off. Now if I don't find out ways to have my precious little Estrogen air tight sealed will they expire really soon or what? They do have lactose or something in them or are they fine if I just tape the opening over? Sorry if this is the wrong area to ask this; I just REALLY NEED to know.

At least I have 280 total tablets so if they are unsafe to take now I'll have plenty 261 tablets left to go back to.

Ziplock bag and squeeze the air out?

Ok.. ok, thank you very much. I was hoping for a simple fix like that, just was not sure how sensitive to environment the tablets are. I tried oogles of Google searches to now avail too.

Your awesome thanks again.

Those holders are far from airtight.
The pills are fine.

They don't need to be airtight. They probably shouldn't be allowed to get wet and then dry again (might partially dissolve before you take them), but the container is for convenience, not to keep the pills hermetically sealed.
