Method of injecting octreotide acetate into the body

A method of treating one or more of acromegaly, carcinoid tumors or vasoactive intestinal peptide tumors by providing and/or injecting octreotide acetate for a subject in need thereof, comprising:

• storing the octreotide acetate in a cartridge of a multi-use multi-dose injector provided with a variable dose setter and an actuator, the injector comprising a needle configured for subcutaneous administration of the octreotide acetate, the octreotide acetate having a concentration of about 2,500 μg/mL;
• permitting setting of a dose of the octreotide acetate by rotation of the variable dose setter, wherein the injector is configured to provide at least one audible feedback during the rotation, and operating the actuator to deliver the octreotide acetate from the cartridge through the needle to treat the subject,
• wherein the injector comprises a first surface portion having a first chromatic or achromatic value, a second surface portion having a second chromatic or achromatic value differing from the first chromatic or achromatic value, and a third surface portion having a third chromatic or achromatic value differing from the first chromatic or achromatic value and the second chromatic or achromatic value,
• wherein the first surface portion surrounds the second surface portion, and the third surface portion is proximate to the first surface portion, and
• wherein operating the actuator to deliver the octreotide acetate comprises providing a daily dose of up to about 1,500 μg in a first session and a second session, and wherein the first session comprises:
• turning the variable dose setter to a maximum dose setting;
• delivering, to a first injection site, a first injection at the maximum dose setting;
• turning the variable dose setter to one of a plurality of indicia;
• and
• delivering, to a second injection site differing from the first injection site, a second injection following the first injection.
