How long amlodipine last shef life?

There should be a date on the prescription label that says a date to use the medicine by. The shelf life is usually around six months to a year. If you can't find a date on the Rx label then call the pharmacy where you got the medication and they should be able to tell you if it is still good. Medicines older than a year could become broken down and may not work as well but some medicines can make you very ill if they are old. The components could break down chemically and change into something toxic. You should definitely not use them if they appear discolored, or if the pill looks like it is desintegrated or crumbling at all.
