They should be fine, especially if they are still sealed in the package.

Midiman is right... they should be fine since the expiration date wasn't too long ago.

Harvard Medical School did a study stating that many medications like this can actually retain their potency for up to 10 to 15 years beyond their expiration date.

The shelf life of Suboxone may be listed as 3 years, but I think it's been proven to retain its potency much longer under proper storage conditions.

I hope this helps!

I take 8 mg suboxone and I only take a small piece of it and then put the rest back in the package. As long as it stays sealed and in a dry place they dont lose alot of their potency.

Yes the subox shelf life is 3 years and seeing the product is sealed you are well within the effectiveness period.
Normally it's environmental factors that can degrade the pharmaceutical but poses no true danger. If this medication was legit rx'd to you then by all means use it. Hope that helps

Thank you so much!! Yes it was prescribed to me of course - I have had the strips sealed in the perscption bottle but they are expired - however I need to take them as my insurance changed and will not cover the new script so I need to take what I have -and I can't afford to pay for it right now- and I will need to take it the expired ones right now - I just got nervous because they are expired. I appreciate your help and quick response! Thank you again!!
