Is Cephalexin Strong Enough to Clear Infection in Breast Implant?
Implants are not part of your body's natural tissue and can be more prone to infection and less able to clear infections compared to your natural tissue. Some doctors will typically use Keflex (cephalexin) in all post-operative cases to reduce the chance of infection. Technique during surgery is even more important, including irrigation of the pocket with triple antibiotic irrigation solution, minimal handling of the implant and meticulous closure. I have treated patients with implant infections (fortunately none of my own). Treatment can include oral antibiotics. Many times, if I truly suspect an infection, IV antibiotics may be required as aggressive treatment can be required. Part of the evaluation may include physical exam and history as well as lab work (checking your white count). Sometimes an infected implant is not salvageable and must be removed. Also, infection can be associated with capsular contracture in the future. Be sure to stay in close communication with your surgeon. Report any changes including fever, increased redness (many times marking the redness with a felt tip pen can be a good way to track whether it is getting larger or smaller) or drainage.
Clinical Context
Early after surgery, some redness and swelling are normal, so your surgeon will watch how things change over time rather than relying on one exam. Redness that stays mild and fades with antibiotics is usually manageable without further surgery. Spreading redness, fever, drainage, or new pain are signs to call your surgeon promptly, since these can signal a deeper infection that may need IV antibiotics or, in some cases, implant removal to protect your health and the final result.
