Usually, the vehicle used for a intramuscular drug contains oil or a "fatty liquid". The amount of liquid injected is generally bigger in an IM injection and the drug might also be more irritative. The nail used is generally bigger and longer.
For these reasons, almost all IM injections are more painful than SC injections.
Can you be more specific? What medicines are you referring to? Subcutaneous injection, Intravaneous injection, Intramuscular injections? Oral dosages?
There really isn't a limit to the number of subcutaneous or intramuscular injections you can get. It can, however, be difficult to find a good vein for more than a couple of intravenous injections.
There are both intramuscular and subcutaneous versions of Depo Provera. IM is more commonly used in the US.
It is more easily absorbed and less painful in the larger muscle's of your rear end.
Iron injections are significantly more effective (both in time and degree of increase) in improving ferritin levels over 30 days than oral tablets.
The best place to give intramuscular in cats is semimembranous and semitendinous muscle...
subcutaneous, becauseIntrdermal injections take along time to absorb into the body due to the extended time it takes the med to diffuse across the dermis.
The advantages of the deltoid intramuscular injection is that as said before is easy accessible and patients are generally a lot more comfortable with exposing their arms as opposed to another body area. Disadvantages to this site are the size of the muscle mass is small in relation to other IM injection sites.
Vaccinations can be given in several ways, usually either intramuscular or subcutaneously. The different methods of injection will cause a different pain-experience in different people. I personally have always found subcutaneous injections more painful than intramuscular injections, but have heard other people say the contrary. The actual injected material won't have any effect on the experience, because all vaccines - especially mainstream ones like these - are designed to only prepare the immune system for the arrival of the actual virus, by triggering it with a non-functioning version of the virus. When the real deal comes along, the body will remember what to do from the vaccination and can deal with the virus with the prepared immune system. The only possible negative from a vaccination, apart from the injection, can be a bad reaction from the body, like a light fever. This is rare and usually passes quickly, but it would be wise to seek council from the organization which administered the vaccine.
three: A subcutaneous bruise is one that occurs just below the skin and will normally be considered mild. At another level, an intramuscular bruise occurs deeper within the belt of the muscle underneath and can cause some more significant damage. An even deeper bruise is a periosteal bruise which refers to a bone bruise, which can be very painful. from http://yourarticlesource.com/Art/60692/85/What-Are-the-Different-Types-of-Bruising.html
These are medical abbreviations therapeutic/ prophylaxis / diagnostic injection subcutaneous and intramuscular which are means to administer or inject the drug based on those three reasons.
IM means Intramuscular route of drug administration, while IV means Intraveinal route of drug administration. IV route, takes the drug directly into the bloodstream resulting in 100% bioavailability instantly. Where as in IM route, drug is injected into muscle tissues, which holds the drug for a while and gradually releases into the bloodstream through the network bed of capillaries running across or surrounding the muscle tissue. In IM, the bioavailability may be slightly less than 100% of drug due to diffusion from muscle through tissue fluid and into the blood.
