Injections at Home: Intramuscular, Subcutaneous and Intravenous Explained
What is the difference between intramuscular, subcutaneous and intravenous injections, and what safety rules apply when a nurse gives injections at home?
Contents
Antibiotic courses, vitamin B12, blood thinners or pain relief: many prescribed medicines are given by injection rather than by mouth. Travelling to a clinic once or twice a day is hard for older people and anyone with limited mobility. With a home injection service, the nurse arrives at the scheduled time and gives the medicine in the right site using the right technique.
Three main routes
| Route | Site | Needle angle | Example drug groups |
|---|---|---|---|
| Intramuscular (IM) | Side of the hip, thigh, shoulder | 90° | Some antibiotics, vitamin injections |
| Subcutaneous (SC) | Abdomen, back of the arm, thigh | 45°–90° | Blood thinners, insulin |
| Intravenous (IV) | Veins of the arm or hand | Via cannula | Fast-acting drugs, infusions |
Why does the site matter?
For hip injections, experienced nurses usually choose the ventrogluteal site on the side of the hip, which keeps the needle away from the sciatic nerve and large blood vessels.
Why do blood-thinner injections bruise?
Small bruises are common. Not rubbing the area and rotating the site each time helps reduce them.
Safety rules
- The medicine must be prescribed and bought from a pharmacy.
- Expiry date, colour and clarity are checked before use.
- For a first dose of some antibiotics, the patient is observed after the injection.
- Used needles go into a puncture-proof sharps box.
After the injection
- Mild soreness usually fades within hours.
- Growing hardness, redness or warmth should be reported to the nurse.
- Rash, swollen lips or breathing difficulty are signs of an allergic reaction: call 112.
For multi-day courses, doses should be given at regular intervals. Our team plans morning and evening visits across Yalova and, by arrangement, in Bursa, Istanbul and Kocaeli–Gebze.
