Emerade® has an 18 months shelf life.

• 300mcg device has a longer needle than Epipen®.

The 150mcg and 300mcg devices are suitable for patients to self-administer.

The 500mcg device should only be used by health professionals although generally most practices use vials to administer doses of 500mcg.

The extended shelf life is a significant advantage as most patients replace their device when it expires rather than because it has been used.
