Norditropin Simplexx is made by Novo Nordisk, Denmark. Norditropin Simplexx manufactured using recombinant DNA technology in E.coli secretion expression system. Norditropin Simplexx is packaged in 15mg (45iu)/1.5ml cartridges of liquid growth hormone formulation to be used with pen.
Most other growth hormones must be refrigerated at all times, but not Norditropin®. It can be kept at room temperature (up to 25 °C – 77°F) if you are going to use them within 21 days. (If you need to maintain the pen for up to 4 weeks, store it in a fridge) This may allow for greater flexibility without having to preplan refrigeration for Norditropin during overnight visits, vacations even last-minute trips.
