Abstract: A case carries an inhaler holding a canister of medicant. An elastically radially deformable cylindrical sleeve is resiliently expandable to slidably axially receive and grip the inhaler. An elastically lengthwise deformable strap stretches diametrically across the sleeve to secure the canister against inadvertent release from the inhaler. A spring clip is connected to the sleeve by a loop for attaching and detaching the case to and from an external object such as a belt loop, fence wire, storage ring or the like. An aperture in the sleeve exposes a portion of the inhaler to display indices, such as the user's initials, uniform number or the like, suitable to distinguish any given inhaler from similar inhalers.
