Is it absolutely necessary to take Antibiotics after Liposuction?

If one looks at the change in infection rate with and without antibiotics, it is difficult to justify the use of perioperative antibiotics. However, if one gets an infection (and the patient is not prescribed antibiotics), it may be extremely difficult to justify the reasons to differ from "the norm", even if it is not agreed that they are the "standard of care". Discuss your concerns (yeast infections, nausea, itching, etc.) with your surgeon. Allow him or her to provide for you the best level of care that has been most successful in their experience.

your case is very particular and you need to discuss it with your doctor as the problem is that you are vomiting after you take the antibiotics, every doctor has his own management book for care after surgery but you will see that most of them will use antibiotics to PREVENT infections so that is the objective of this. Best wishes and get well soon.
