because it takes time to process. 8 months is enough time
2 months
About 6 months after the date.
No
It's not, once a drug hits the expiration date it should be discarded -
6 months after date of issuance
Expiration dates mean the date that the drug is full-strength. After that date, it's no longer as effective. You can take it, but it probably won't work well.
The expiration or best-use-by dates are for unopened packages.
If they were frozen before the expiration date, there shouldn't be a problem. If they have been in the refrigerator, toss them.
3 months afterwards
Heineken no longer puts an expiration date on its bottle. Instead they are stamped with a date of manufacture or 'birth'. The expiration is nine months after this date.
You must renew it by the expiration date.
It is usually one month of opening the bottle, and three months from date of maufacturinf, whichever is earlier
