Hi Alice,

I wanted to know the dangers of taking expired pills. For instance, Xanax that expired over five years ago. I'm sure you're wondering why someone would still have them but I am curious what would happen if you took them now.

Thank you,

Dear Diney,

With all the different labeling we see now — best by, sell by, use by, and more — it’s easy to be confused by expiration dates. Although in some cases medication is still safe after the expiration date, prescription and non-prescription medicines are only guaranteed to be safe and at full potency up until the expiration date listed on the bottle. You specifically mentioned expired alprazolam (the generic name for Xanax ®) in your question. Disposing of alprazolam that is either expired or no longer needed is typically recommended. Your best bet is to refrain from using the expired medication and consult your health care provider for a new prescription.

So, more about expiration dates: Because manufacturers must be absolutely certain that the drugs will be at full strength up until the expiration date, the expiration date is often conservative. The result of a conservative expiration date is that some medications do stay potent and safe beyond that date. Some studies have looked at expired medicine to see just how long different types will last beyond their expiration date. Although evidence supports the fact that certain medications retain their power long beyond the expiration date, it’s good to note that the studies tested medication that was stored in ideal conditions (in some cases, the medicine bottles had never been opened at all before testing). It’s also helpful to remember that research has not been done on every type of medication available and that some expired medications have been shown to be unsafe to consume, so caution is still recommended.

So, how can you store your medication in the best way possible? If the medication looks or smells a bit off in any way — including before the expiration date — check with your health care provider to see if these observed changes might be a sign that it has gone bad.

Time to toss the meds? The U.S. Food and Drug Administration (FDA) recommends taking the following steps to properly get rid of expired medications:

  • Check the medication’s label for instructions on how to dispose of that medication specifically.
  • If no specific instructions are given, look for a government-run drug take-back program in your area. The U.S. Drug Enforcement Administration (DEA) lists collection sites available to the public.
  • If no drug take-back options are available near you, some medications can be thrown away in the trash. Putting the unused medicine mixed with an unappealing substance (like coffee grounds) into a plastic bag before throwing it away with the other garbage is recommended. Avoid cushing pills when mixed with the coffee grounds or other substance.
  • Before throwing any medicine away, check to make sure it’s not on the FDA’s list of medications that are better flushed down the toilet than thrown away. It’s also a good idea to block out any personal information on medication labels before throwing away the bottles, either by scraping off the label or scribbling over it with a permanent marker.

At the end of the day, when it comes to putting medication in the body, it’s better to be safe than sorry. If you’re interested in taking medication, talking to your health care provider about getting a prescription is the way to make sure the medication you take will be both potent and safe.
