The night before your surgery

You have spent much time and energy going to appointments, preparing your home, and getting healthy. Now it is time for surgery. You may feel relieved or nervous at this point.

Taking care of a few last-minute details can help make your surgery successful. Depending on the type of surgery you're having, follow any further advice from your health care provider.


One to two weeks before surgery, you may have been told to stop taking blood thinners. These are medicines that make it harder for your blood to clot and could prolong bleeding during your surgery. Examples of these drugs include but are not limited to:

  • Aspirin
  • Ibuprofen (Advil, Motrin)
  • Naproxen (Naprosyn, Aleve)
  • Clopidogrel (Plavix), warfarin (Coumadin), dabigatran (Pradaxa), rivaroxaban (Xarelto), apixaban (Eliquis)

Take only the medicines your doctor has told you to take before surgery, including prescription medicines. Some of these medicines have to be stopped a few days before surgery. If you're confused about which medicines to take the night before or the day of surgery, call your doctor.

Do not take any supplements, herbs, vitamins, or minerals before surgery unless your provider said it is OK.

Bring a list of all your medicines to the hospital. Include the ones that you were told to stop taking before surgery. Make sure you write down the dose and how often you take them. If possible, bring your medicines in their containers.

Washing Your Skin

You may take a shower or bath both the night before and the morning of surgery.

Your provider may have given you a medicated soap to use. Read the instructions for how to use this soap. If you were not given medicated soap, use antibacterial soap that you can buy at the store.

Do not shave the area that will be operated on. The provider will do that at the hospital, if needed.

Scrub your fingernails with a brush. Remove nail polish and makeup before you go to the hospital.

Eating and Drinking Before Surgery

It is likely that you have been asked not to eat or drink after a specific time the evening before or day of surgery. This usually means both solid foods and liquids.

You may brush your teeth and rinse your mouth in the morning. If you were told to take any medicine on the morning of surgery, you may take them with a sip of water.

Symptoms to Report

If you do not feel well in the days before or on the day of surgery, call your surgeon's office. The symptoms your surgeon needs to know about include:

  • Any new skin rashes or skin infections (including herpes outbreak)
  • Chest pain or shortness of breath
  • Cough
  • Fever
  • Cold or flu symptoms
