Medication administered via intramuscular injection is not subject to the first-pass metabolism effect which affects oral medications.  Injections offered by Vital injections include Migraine, Toradol, Decadron, Benadryl, Vitamin B12, Zofran, MICC, and Lipo-mino.  Common sites for intramuscular injection include the deltoid muscle of the upper arm and the gluteal muscle of the buttocks.  The volume of substance injected is usually between 2-5 cc depending on the site and medicine.  Any site with signs of atrophy or infection should not be chosen.  Here at Vital injections a prenumbing spray will be used to make the patient as comfortable as possible.
