(CNN) – Experts say using an expired drug is probably ok if you have a minor health issue such as a headache or sinus trouble.
If your condition is serious, don’t chance it.
Many medicines, especially tablets and capsules have a shelf life well beyond the date on the bottle.
Dr. Sharon Bergquist – Emory School of Medicine: The reality is that because these expiration dates are so conservative probably even 5 – 10 years from the time of the expiration date a person can try still using their product.
But even with medications that are long expired the amount of effectiveness is usually over 90%.
There are certain medicines, that should not be used beyond the expiration date, often because they treat chronic conditions such as heart disease or diabetes where 100% potency is crucial.
