Intramuscular (IM): An intramuscular (IM) medication is given by needle into the muscle. This is as opposed to a medication that is given by a needle, for example, into the skin (intradermal) or just below the skin (subcutaneous) or into a vein.
BTW: TB is intradermal not subq. IM injections need to go into the muscle for optimal absorption and include many meds such as antibiotics, vaccinations. Muscles can absorb more fluid in the shot as well (so can be a Bigger volume). Subcutaneous (subq) goes into the deeper layers of the skin but not into muscle. Examples are insulin, epinephrine, lovenox; the volume is a lot less as well. Subcutaneous is just under the skin and IM means intramuscular, or into the muscle. subcutaneous is a smaller and thinner needle that is just injected under the skin, it is usually around 1/3 of an inch and the gage of the needle is small almost always. IM is a longer needle and the gage is thicker, this is due to the fact that it has to be injected into the muscle.
