What should I do if no growth hormone appears when I prime the Norditropin® NordiLet® pen?
Repeat dialling one click until a drop of growth hormone appears at the tip of the needle. If not, repeat the procedure no more than 6 times. If a drop of growth hormone still does not appear, the pen is faulty and must not be used. If considered faulty, take it back to your supplier for a new one.
