Treatment of induration after fulvestrant/Fuxit injection

Induration after injection of fulvestrant (Fulvestrant) is a relatively common side effect, especially in patients with breast cancer who have had multiple injections. Induration usually manifests as localized swelling, pain, and a hard lump at the injection site. These symptoms usually appear within a few days after the injection and may last for several weeks. Although induration does not often affect the effectiveness of treatment, it may cause discomfort to the patient and even affect the choice of injection site.

The occurrence of induration is mainly due to the local accumulation and slow release of the drug after the drug is injected into the muscle. Drugs may irritate local tissues and cause an inflammatory reaction, resulting in the formation of induration. In order to reduce this side effect, patients can adopt the following management strategies:

1. Massage and hot compress: Within a few hours after the injection, the patient can try to gently massage the injection site and use a warm towel for hot compress, which can help improve blood circulation, promote drug absorption, and thereby reduce the formation of induration.

2. Change the injection site: If induration occurs repeatedly in a certain site, the patient should consider discussing with the doctor about changing the injection site. Usually, the injection sites of fulvestrant should be chosen in different locations in rotation to reduce the occurrence of local irritation and induration.

3. Cold compress to relieve swelling: For local swelling after injection, patients can try to use cold compress to relieve discomfort. Cold compresses help constrict blood vessels and reduce inflammation and swelling.

4. Drug management: If the induration is severe or accompanied by obvious redness, swelling, and pain, you may need to seek medical treatment in time. Your doctor may recommend anti-inflammatory medications or other topical treatments to reduce inflammation and discomfort.

5. Improvement of injection techniques: Doctors or nurses should ensure that the injection depth is correct when injecting, and avoid injecting drugs into the lower layers of the skin or irregular injections to reduce local reactions.

Overall, the development of induration after fulvestrant injection is a relatively common side effect that can usually be alleviated with appropriate care.
