Side Effects of Blood Draw

Most blood draws cause minimal side effects. However, it’s possible you could experience some of the following:

• bleeding
• bruising
• lightheadedness
• rash
• skin irritation from tape or adhesive from an applied bandage soreness

Most of these will subside with time. If you still experience bleeding from a puncture site, try holding pressure with a clean, dry gauze for at least five minutes. If the site continues to bleed and soak bandages, see a doctor.

You should also see a doctor if you experience a large blood bruise known as a hematoma at the puncture site. A large hematoma can block blood flow to the tissues. However, smaller (less than dime-sized) hematomas will often go away on their own with time.
