Plasma donation is a generous act that provides life-saving therapies for individuals with various medical conditions. Plasma-derived medicines treat chronic illnesses, rare conditions, and medical emergencies. However, like any medical procedure, it's essential to understand the potential side effects and considerations before donating. This article explores the side effects of donating plasma, its benefits, and important factors to consider.
What is Plasma and Plasma Donation?
Plasma, the liquid portion of blood, constitutes about 55% of its total volume. It contains water, salts, nutrients, and essential proteins like clotting factors and antibodies. Plasma is vital for treating burns, shock, trauma, clotting deficiencies, and severe liver disease.
During plasma donation, blood is drawn from the arm and sent through a machine that separates the plasma from other blood components through a process called plasmapheresis. The remaining blood components, such as red blood cells, white blood cells, and platelets, are returned to the donor's body, mixed with saline to replace the withdrawn plasma. Plasma regenerates in about 48 hours after donation, much faster than the one to two months it takes for whole blood to fully replenish.
Common Side Effects of Plasma Donation
While plasma donation is generally safe, some donors may experience mild, immediate side effects. It's important to note that these side effects are usually temporary and manageable.
Dehydration: Plasma is over 90% water, so removing it can lead to mild dehydration. Donors are encouraged to drink plenty of fluids before and after donation to combat this.

Dizziness, Lightheadedness, or Fainting: Plasma contains salts, vitamins, and minerals (electrolytes) that help regulate the body's functions. Donating plasma may cause mild electrolyte imbalances, leading to dizziness, lightheadedness, or fainting.
Fatigue: Dehydration and electrolyte imbalances can contribute to fatigue after donating plasma. Resting and eating a healthy, well-balanced meal with high protein can help replenish lost nutrients and energy.
Bruising or Discomfort: Bruising may occur at the needle insertion site. Donors may also experience some discomfort during the donation process, often described as a slight pinch or bee sting.
Infection or Inflammation: There is a slight risk of infection any time a needle is used to pierce the skin. Signs of infection include pain, swelling, or warmth at the needle insertion site.
Rare Side Effects of Plasma Donation
Although less common, more serious side effects can occur.

Citrate Reaction: During plasmapheresis, an anticoagulant called citrate is used to prevent blood clots. While most of the citrate remains in the machine, some enters the donor's bloodstream and binds to calcium molecules. In rare cases, this can lead to a citrate reaction, with symptoms such as numbness or tingling, muscle twitching, chills, and a rapid or slow pulse. Severe symptoms like spasms, vomiting, shock, or cardiac arrest require immediate medical attention.
Arterial Puncture: In rare cases, the technician may accidentally puncture an artery instead of a vein. This can lead to bleeding into the arm tissues around the puncture site. The technician will remove the needle immediately and apply pressure to the site.
Nerve Injury: On rare occasions, a technician might hit a nerve upon inserting or withdrawing the needle. It will instantly send a sharp pain down the donor’s arm and cause general weakness in that arm. The technician must stop the procedure immediately and tend to the affected area with a cold compress.
Low Immunoglobulin Levels: Those who donate frequently and long term may also be at risk for anemia from incidental loss of red cells during donation.
Managing Side Effects
Most side effects of plasma donation are manageable and fade within a day. Here are some tips to minimize adverse reactions:

- Drink lots of water before and after donating.
- Have a light meal or snack before donating.
- Avoid strenuous physical activity after the procedure.
- If you feel numbness, tingling, or bruising at the injection site, elevate the arm and apply a cold compress for the first 12-24 hours, followed by a warm compress.
- If you feel dizzy afterward, have someone drive you home or stay in the facility's recuperation area longer.
- Eat a healthy, well-balanced meal with high protein to help replenish some protein lost during donation.
Benefits of Plasma Donation
Donating plasma offers numerous benefits, both for the recipients of plasma-derived therapies and for the donors themselves.
- Saving Lives: Plasma is essential for creating life-saving therapies used to treat various medical conditions. Donating plasma helps create plasma-derived medicines that treat chronic illnesses, rare conditions, and medical emergencies.
- Personal Well-being: Knowing that you've helped save lives can improve your mood and mental well-being.
- Financial Compensation: Many plasma donation centers compensate donors for their time, providing a financial incentive for this altruistic act.
- Stimulating New Blood Cell Production: Donating plasma encourages your body to produce new blood cells, which can enhance your immune system over time.
- Refresh Circulatory System: The process can stimulate the production of new blood cells and refresh your circulatory system. This renewal indirectly supports the body’s natural detoxification processes by maintaining healthy blood circulation and encouraging the body to optimize its internal functions.
Plasma Donation and Weight Loss: Is There a Connection?
While donating plasma is not a weight loss program, it does involve bodily processes that contribute to calorie loss. During plasma donation, your metabolic rate temporarily increases as your body mobilizes resources to adjust to the loss of plasma. Your body needs to regenerate essential proteins and restore homeostasis, which requires energy.
Depending on how much you donate, plasma donation can burn between 450 and 650 calories per session. Additionally, the body burns calories to replenish lost plasma, and some studies suggest that donating plasma may lower bad cholesterol, reducing cardiovascular risk.
It's important to reiterate that plasma donation should not be considered a substitute for a healthy diet and exercise.
Eligibility and Safety
To ensure donor safety, plasma donation centers have specific requirements. Generally, eligible donors must:
- Be in good health
- Be between 18 and 74 years old
- Weigh at least 110 pounds
- Have no tattoos or piercings within the last 4 months
- Meet eligibility and screening requirements
- Have valid identification and a permanent address
Individuals with certain conditions, such as AIDS or HIV, or those at risk of contracting HIV, should not donate plasma.
The Food and Drug Administration (FDA) regulates plasma collection in the United States, ensuring that the process remains safe for donors. The FDA recommends spacing donations at least two days apart and limiting them to twice within a seven-day period.
Misconceptions About Plasma Donation
Several misconceptions surround plasma donation.
Misconception #1: Donating plasma is bad for you. A health screening is conducted before each donation to prevent anyone whose health could be compromised from donating. After donation, the body replenishes the fluid and proteins given in about 48 hours. Studies have not found any long-term health issues associated with frequent plasma donation.
Misconception #2: People who donate plasma are only motivated by compensation. While compensation is a factor for some, many donors are motivated by altruism and the desire to help others.
Misconception #3: Paying people to donate plasma is bad. Offering compensation to donors helps ensure a steady supply of plasma to create life-saving products.
