Yes, it is allowed to take antibiotics before surgery. Suspending the antibiotic may increase the risk of resistance to treatment, so it is usually kept before the operation.
This is for both antibiotics used to treat acute infections and those used for longer treatments, such as tuberculosis.
During the preoperative period, abrupt and profound changes in the use of medications should be avoided in order to avoid decompensation of the underlying disease, which can be much more detrimental than keeping the medication.
If it is really necessary to stop taking the antibiotic before surgery, your doctor will let you know. Therefore, it is essential that you inform in the preoperative consultation all the medicines that you use.
However, depending on the surgery, during the fasting period it may not be possible to continue taking the medicine.
In such cases, the antibiotic may be administered intramuscularly, intravenously or even enterally via probes.
For further clarification, speak with the doctor who will perform the surgery or ask your questions during the interview with the anesthesiologist.
