Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.
Environmental conditions can impact the chemical and physical properties of medications and shorten the shelf-life. So if you have over a year that you have this tablets I think that the effectiveness will be very low.
Hope I have answered your query. Let me know if I can assist you further.
