While it is considered a safe procedure, blood transfusions in patients may cause discomfort. Common side effects of blood transfusions can include these issues:
- Symptoms of an allergic reaction
- Difficulty breathing
- Chest pain
- Sudden drops in blood pressure
These mild side effects of blood transfusions do not affect every patient, and they can occur even if the donated blood is the correct blood type. It can be fatal to receive transfusions with the wrong blood type, but rest assured the blood is checked many times by medical personnel before it is administered.
