The invention concerns a nebulizer (1) for aerosolizing a liquid, such as a drug-containing solution, comprising a nebulizer body (2) comprising a nasal interface (10) comprising a hollow body (11) defining an inner chamber (16), and two nasal prongs (12) to be inserted into the nostrils of a user (20), each nasal prong (12) comprising an inner channel (13) in fluid communication with an inner chamber (16) of the hollow body (11) of the nasal interface (10). The nasal interface (10) is detachably fixed to the nebulizer body (2). The hollow body (11) and the two nasal prongs (12) of the nasal interface (10) are made of a flexible soft material. The nebulizer (1) of the present invention is usable in combination with a source of gas, such as compressed air, for nebulizing a drug-containing solution and thereby obtaining a mist containing droplets of medication having suitable sizes so as to be able to reach the lower airways of the patient that has to inhale said mist in the frame of his/her aerosoltherapy.
