What are the disadvantages of intramuscular injection?

Disadvantages
Expert and a trained person is required for administrating the drug by IM route.The absorption of the drug is determined by the bulk of the muscle and its vascularity.The onset and duration of the action of the drug is not adjustable.

What can go wrong with an intramuscular injection?

The microbes in injection substances, injection equipment or already-existing on the skin, can enter the body causing very serious infections. Similarly, incorrect injection techniques or erroneous injection locations, can cause blood vessel breakage, muscle or nerve damage and paralysis.

What are the disadvantages of intramuscular or subcutaneous injection of medication?

Intramuscular injections commonly result in pain, redness, and swelling or inflammation around the injection site. These side effects are generally mild and last no more than a few days at most. Rarely, nerves or blood vessels around the injection site can be damaged, resulting in severe pain or paralysis.

What’s going on? Intramuscular injections are among the safest, and anyone can be trained to do them. However, things can occasionally go wrong. Aspiration is the term for pulling back a little on the syringe before injecting to be sure you aren’t in a blood vessel.

What are the disadvantages of injection route of administration?

Possible side effects
Infection. Infection can occur at the injection site. Damage to veins and injection site. A vein can be damaged during injection or by the use of an IV catheter line. Air embolism. If air gets into the syringe or the IV medication bag and the line runs dry, air bubbles can enter your vein. Blood clots.

However, within 30 minutes or so, more serious symptoms can develop, including:
Coughing, wheezing, and shortness of breath.Chest tightness.Hives.Dizziness or fainting.Rapid or irregular heartbeat.Weak pulse.Facial swelling.Swollen or itchy lips or tongue.

What happens if im injection is too high?

“A vaccine is an immunologically sensitive substance, and if you were to receive an injection too high – in the wrong place – you could get pain, swelling and reduced range of motion in that area,” says Tom Shimabukuro, deputy director of the Centers for Disease Control and Prevention’s immunization safety office.

What is the advantage of intramuscular injection?

Intramuscular injections have other advantages too. The muscles have a plentiful supply of blood, which helps ensure that the body absorbs the medication quickly. The tissue in the muscles can also hold more medication than fatty tissue. Doctors administer most injectable vaccines into the muscles.

Advantages include rapid absorption in many cases, often in under 30 min. Other advantages of the im route include the opportunity to inject a relatively large amount of solution and a reduction in pain and local irritation compared with sc injections. Potential complications include infections and nerve damage.

Why does my intramuscular injection hurt?

If you have ever received a vaccination, you know your arm may feel a bit sore for a few days after the fact. The pain you are experiencing is usually soreness of the muscle where the injection was given. This pain is also a sign that your immune system is making antibodies in response to the viruses in the vaccine.

Which im injection sites are safe?

Based on these three conditions, deltoid, ventrogluteal, and thigh sites are considered to be safe and, thus, commonly used for IM injections. The deltoid site has been used in clinical settings and is preferred in Japan because it is easily accessible for clinicians and also for patients to expose.

Can an injection cause muscle damage?

Specifically, SIRVA occurs when an intramuscular deltoid injection is administered into the shoulder joint. This results in an inflammatory process that causes damage to the musculoskeletal structures including the bursae, tendons, and ligaments.

Disadvantages of topical route of drug administration

Most drugs have a high molecular weight and are poorly lipid-soluble, so are not absorbed via skin or mucous membranes. 2. Possibility of local skin irritation at the site of application. 3.

What are the advantages and disadvantages of using the parenteral route of administration?

What are the advantages and disadvantages of using the parenteral route of administration? They are absorbed more rapidly and completely than medications given orally. If the patient is unconscious the parenteral route may be the only available.

What are the advantages and disadvantages of parenteral routes of administration?

Box 1. Parenteral administration
Can be used for drugs that are poorly absorbed, inactive or ineffective if given orally.The IV route provides immediate onset of action.The intramuscular and subcutaneous routes can be used to achieve slow or delayed onset of action.Patient concordance problems can be avoided.

At what angle do you give an IM injection?

Insert needle at a 90o angle to the skin with a quick thrust. Retain pressure on skin around injection site with thumb and index finger while needle is inserted. Aspiration is not necessary. Multiple injections given in the same extremity should be separated as far as possible (preferably at least 1” apart).

Drugs may be given intramuscularly both for prophylactic as well as curative purposes, and the most common medications include[2]:
Antibiotics- penicillin G benzathine penicillin, streptomycin.Biologicals- immunoglobins, vaccines, and toxoids.Hormonal agents- testosterone, medroxyprogesterone.
