The shot must be injected into thigh, buttock, or deltoid muscle four times a year (every 11 to 13 weeks), and provides pregnancy protection instantaneously after the first injection. [68] Depo-subQ Provera 104 is a variation of the original intramuscular DMPA that is instead a 104 mg microcrystalline dose in aqueous suspension administered by ...
EC/MPA is available in the form of a microcrystalline aqueous suspension of 5 mg EC and 25 mg MPA given in a 0.5 mL aqueous solution for intramuscular injection once per month. [10] It is provided in the form of single-dose vials and ampoules. [10] The particle sizes of the formulation are 93% within a range of 5 to 16 μm. [11]
CICs are administered by intramuscular injection into the deltoid, gluteus maximus, or anterior thigh. [1] They are ideally administered every 28 to 30 days, though they have been demonstrated to be effective up to 33 days.

Intramuscular injection, often abbreviated IM, is the injection of a substance into a muscle. In medicine , it is one of several methods for parenteral administration of medications. Intramuscular injection may be preferred because muscles have larger and more numerous blood vessels than subcutaneous tissue, leading to faster absorption than ...
The term injection encompasses intravenous (IV), intramuscular (IM), subcutaneous (SC) and intradermal (ID) administration. [35] Parenteral administration generally acts more rapidly than topical or enteral administration, with onset of action often occurring in 15–30 seconds for IV, 10–20 minutes for IM and 15–30 minutes for SC.

[60] [93] For comparison, the dose of medroxyprogesterone acetate (MPA; 6α-methyl-17α-hydroxyprogesterone acetate), a close analogue of hydroxyprogesterone caproate, used by intramuscular injection in microcrystalline aqueous suspension in once-a-month combined injectable contraceptives, is 25 mg. [60] [81] It has also been said that given by ...
[citation needed] When free steroids like estradiol are administered in oil solution by intramuscular injection, they are rapidly absorbed and the duration is relatively short. [270] [275] A single 1 to 2 mg dose of estradiol in oil solution by intramuscular injection has a duration of about 1 or 2 days.
