Don't eat or drink anything after midnight, the night before your surgery.

If you're taking a medicine that has a morning dose - you should ask your doctor if he or she wants you to stop the medication the night before, or take the medicine with a small sip or water at an earlier time.

Call your doctor if you develop an acute illness or have an asthma attack within three days of your scheduled surgery.

If you are exposed to measles, mumps or chicken pox within 21 days of the procedure, you should also notify your doctor. He or she may want to consider rescheduling the procedure.

Avoid aspirin and anti-inflammatories for one to two weeks prior to any surgical procedure, unless your doctor tells you otherwise.
