Medicine injection apparatuses having multiple chambers. The chambers may be in lateral relationship. A torsional part is adapted to turn and be repositioned angularly relative to a main body to allow different chambers to be used to receive an injection assembly. The medicine injector can be constructed to administer multiple doses. The apparatuses may also have a storage chamber for storing the injection assembly after use. Plural drivers may be used to administer multiple doses, such as at the different angular positions of the torsional part. The apparatuses may allow multiple automatic injections from different angular positions and storage of an injector after use. Needle fright is reduced by minimizing exposure of an injection needle prior to injection.
