reinjektion

Reinjektion, or re-injection, is the administration of a substance by injection after a prior injection of the same substance or a similar formulation. It is used to maintain therapeutic levels, deliver a booster dose, or continue a treatment plan over time. Reinjections can be given through different routes, most commonly intramuscular, subcutaneous, intravenous, or intra-articular injections, and may be performed in clinical settings or at home under specific instructions.

In medical practice, reinjection serves several purposes. Vaccines often require booster injections to sustain or enhance immunity. Therapeutic injections, such as corticosteroids into joints or soft tissues, are used to reduce inflammation and pain when initial treatment is insufficient. Some chronic therapies involve repeated injections of hormones, biologics, or other medications to achieve ongoing control of a condition. In anesthesia or pain management, reinjections may be used to extend the duration of analgesia or anesthesia.

Safety and technique are essential in reinjection. Aseptic technique, correct needle size, and appropriate site selection are important to minimize infection, tissue damage, and bleeding. Careful dosing and monitoring for adverse reactions, including allergic responses or local tissue effects, are required. Patients should be informed about signs of complications and when to seek medical advice. Reinjec­tion plans should be personalized, considering timing, route, and the patient’s medical history.
