The patient should use the original bottle when carrying it, instead of putting it in other bottles or first aid boxes. The validity period of nitroglycerin is generally one year. If the medicine needs to be opened and taken repeatedly every day, the validity period of the medicine will be shortened to 3-6 months under the influence of temperature, humidity and light.
