Hello, Calvin!

This medication is not listed by the FDA as becoming dangerous, once expired, but it does start to lose effectiveness, so in my opinion it would actually be best to dispose of it and see your doctor for a new prescription.

However, according to the following article (listed below) from NIH, “the expiration date doesn't really indicate a point at which the medication is no longer effective or has become unsafe to use”, and is more of an arbitrary date based on the whit and whim of the pharmaceutical companies’ product “guarantee” that the labeled potency will last “at least” until that date.

The article also goes on to note that while a medication's potency gradually decreases starting from the moment of its manufacture, this process is not in any way spontaneous after the expiry date.

"Ongoing research shows that stored under optimal conditions, many drugs retain 90% of their potency for at least five years after the labeled expiration date, and sometimes longer. Even 10 years after the expiration date many pharmaceuticals retain a significant amount of their original potency. Solid dosage forms, such as tablets and capsules, are most stable past their expiration date. Drugs that exist in solution or as a reconstituted suspension may not have the required potency if used when outdated."

Additionally, this isn't a medication that you can just take as needed, when you have anxiety. In order for it to be effective, it must be taken regularly for several weeks.

Its typical side effects may possibly include nausea, dizziness, headache and dry mouth.

Is there anything else I can help with?
