Intralesional steroid injection is used for preventing and treating raised scars such as hypertrophic scars and keloids. It is mostly the primary option. It involves injecting a corticosteroid medication into the raised area of the skin. This helps to shrink the keloid and reduce symptoms such as itchiness and pain.
Steroid injections are typically given every four to six weeks, and multiple injections may be necessary for optimal results. This treatment option is most effective when used in conjunction with other keloid treatments, such as pressure dressing or silicone gel sheeting.
Intralesional steroid injection is typically performed in a doctor's office. One of the experienced doctors will perform a detailed examination and medical consultation before the treatment. The area to be injected is first cleansed with an antiseptic solution. Then, a local or topical anaesthetic will be injected or applied to reduce discomfort before the injection. A small needle is then used to inject the steroid medication into the keloid.
After the injection, a pressure dressing or silicone gel sheeting may be applied to the area. It is important to keep the dressing in place for 24 hours after the injection to help reduce swelling and discomfort. The patient will be asked to come for an evaluation after one month.
The physician may prescribe intralesional steroid injection keloid until improvements are visible or for about four to six weeks.
