After Your Blood Draw
Reactions to blood draws are rare and, if they occur, are usually mild. Side effects are similar to those experienced by some people following a blood donation. Experts generally recommend the following precautions:
- Wait at least 15 minutes before removing the bandage.
- If you feel dizzy or lightheaded, lie down immediately and elevate your legs until the feeling passes.
- In rare cases where bleeding occurs after removing the bandage, apply pressure to the site of the bleeding and raise your arm for 3 to 5 minutes.
- If bleeding or bruising occurs under the skin, apply a cold pack to the area periodically for the first 24 hours.
- For 12 hours after your blood draw:
Avoid heavy lifting.
Drink plenty of fluids and avoid strenuous exercise.
Eat a healthy meal.
Contact your doctor if you:
- Continue to feel nauseated, lightheaded or dizzy after resting, eating or drinking.
- Feel pain or tingling down your arm, into your fingers.
