Revia-Expiration Date

[Guest guest]

I ordered 2 28 count packs from Medsmex back in Oct.05 to

try and keep on hand so I would not run out. Both have the

same expiration date of February 07. Should I store in the freezer?

Will it be effective after the expiration date? Any help would

be greatly appreciated. I don't have a doctor who will prescibe.

Thanks,

Loretta

Typically any tablet form of a drug will have a two year shelf life if

stored out of the sunlight and in normal home / office temperature and

humidity conditions. Drugs are typically not tested past the two year

point. There are two main reasons for not testing past two years.

The first is that every test done on a product that is on the market

requires a tremendous amount of extreme care and resources. The

product has to be stored in controlled conditions, the storage

conditions have to be recorded. All of the lab data is extremely

controlled and well documented. All of these records are

kept...forever. Even the record storage procedures are well

controlled. The second reason is " pharmaceutical elegance " . If a

product has been sitting on a shelf for two years, the packaging will

be dusty, faded, dented, etc. Who wants to have a bad looking product

out there representing their company?

When a pharmeceutical company runs a stability study, the control

samples are stored at 5F. The tablets and dessicant are put in HDPE

bottles. The bottles have induction sealed foil covers. The bottles

are then sealed into heavy duty plastic-foil heat sealable bags.

Having said all of that, many products are effective well after the

expiry date. Store them in the deep freeze. If possible put them in a

sealed container along with some freshly baked dessicant. I do not

have the data to suggest how far to push the expiry date. The

Department of Defense did a " stability study " of common drugs a few

years ago. Maybe DOD has some data on naltrexone?? This study was

written about in the New York Times.
