A syringe (18) has a longitudinal body (28) with an interior (228) in which a pharmaceutical substance is arranged, a needle connected to one longitudinal end of the body (228) and a rigid needle shield (38) encasing the needle. The rigid needle shield (38) is essentially water vapour tight. The syringe (18) according to the invention allows for preventing needle clogging and, thus, proper provision of pharmaceuticals, particularly by subcutaneous, intramuscular or ocular injection.
