Amoxicillin is an antibiotic used to kill susceptible micro-organisms responsible for bacterial infections. Amoxicillin is available as capsules, tablets and a suspension.
The expiry date is the last day that the pharmaceutical manufacturer guarantees the safety of the medication and it is mandatory on every medicine. The expiry date is estimated by stability testing. Amoxicillin capsules and tablets will have an expiry of around 2 years and provided they are stored as recommended and in the original packaging there will be a small lee way of safety if used beyond expiry.
The amoxicillin suspension is different and has a very short shelf life of about 10 days once it is opened.
On a slightly different note antibiotics should be used only for whatever they were prescribed for and to whom.
Also, with most antibiotic courses they are prescribed to be taken "until finished".
Yes, all antibiotics lose effectiveness in time. It won't make you sick, but probably won't make you well either. Here is the real problem. Amoxicillin is a good antibacterial drug. Let's say that you had some left from a round of strep. Three years later you get it again and take the script you didn't finish. The Amoxicillin is weakened over time and this could result in you making a drug resistant infection in your body. When in doubt, throw it out.
