I took sertraline for 1.5 years. havent taken it for awhile but im depressed and its worse. the discard date was 12/05/2016. can i still take it?

Yes: An article came back recently testing bioavailability of some medications dating back up to 50 years and found many of them still active. The manufacture of meds thru the FDA process puts a time limit of guarantee by the producer but that does not mean it will not be effective at a later date. effectiveness of treatment is quite possible but consult w a professional
