Donating plasma is generally a safe and generous act that can save lives. However, like any medical procedure, it’s associated with certain potential side effects and risks. Understanding these is crucial for making an informed decision about whether plasma donation is right for you. This article explores the reasons why some individuals might hesitate or should not donate plasma, focusing on potential health concerns and reactions.
Common Side Effects of Plasma Donation: What to Expect
While most plasma donors experience no significant issues, some common side effects can occur, primarily related to the donation process itself.
Feeling Faint or Dizzy
Feeling faint or fainting is a known reaction to blood donation and can also occur during or after plasma donation. This can manifest as dizziness, light-headedness, feeling hot, sweaty, or nauseous. While only a small percentage of donors faint, it’s important to be aware of this possibility as fainting can sometimes lead to injuries.

Bruising at the Needle Site
Bruising is another common side effect, resulting from the needle insertion. Small bruises are typical and usually resolve within a few days. However, larger bruises can occasionally develop, causing discomfort and taking several weeks to heal.

Risks Associated with Plasma and Platelet Donation: Citrate Reactions
Plasma and platelet donations involve a process called apheresis, where blood is drawn, components like plasma or platelets are separated, and the remaining blood is returned to the donor. To prevent clotting during this process, an anticoagulant called citrate is used. Citrate can lead to some specific reactions.
Citrate Sensitivity
A mild sensitivity to citrate is relatively common. This occurs because citrate binds to calcium and magnesium in the blood. Symptoms of mild citrate sensitivity can include:
- Chills
- Tingling of the lips or tongue
- Metallic taste
Moderate symptoms are less frequent but can include:
- Tingling in hands or feet
- Shivering
- Muscle twitching
Rare but Serious Citrate Reactions
Severe reactions to citrate are very rare due to safety protocols, but it’s important to be aware of the potential, albeit low, risk. These severe reactions can be life-threatening and may include:
- Muscle contractions or spasms: Involuntary muscle movements due to severe calcium depletion.
- Seizures: Abnormal electrical activity in the brain, triggered by electrolyte imbalances.
- Brebreathing difficulties: Citrate can affect respiratory muscles in extreme cases.
- Disturbance of heart rhythm: Electrolyte imbalances can impact the heart’s electrical system.
Other Very Rare Events in Apheresis
While extremely uncommon, other serious events related to the apheresis procedure are possible:
- Damage to red cells in the machine: If damaged red blood cells are returned in a significant volume, it can lead to:
- Blood in the urine
- Fevers
- Back pain
- Fortunately, healthy individuals typically experience no long-term side effects from this.
- Disruption to citrate delivery causing clotting in tubing: If clotted blood is returned, it could block a blood vessel. Symptoms may include:
- Dizziness
- Breathlessness
- Coughing
- Chest pain
- Limb swelling
- Entry of air into the collection line (air embolus): If air enters and is returned to the donor, it can block blood vessels, leading to:
- Breathlessness
- Chest pain
Risks for Frequent Platelet Donors
Donating platelets frequently exposes donors to higher amounts of citrate compared to plasma-only donations. While citrate causes a temporary drop in calcium levels, studies have not consistently linked frequent platelet donation to long-term bone health issues.
However, some research suggests a possible reduction in a specific type of white blood cell (lymphocyte) in some frequent platelet donors. Further research is ongoing to determine if there are any long-term health consequences associated with this, but currently, there’s no confirmed evidence of harm.
Needle-Related Reactions: Beyond Bruising
Needle insertion can cause reactions beyond simple bruising. Here’s a breakdown of other potential needle-related issues:
| Reaction | Description |
|---|---|
| Nerve irritation | Transient shooting arm pain or pins and needles in the arm or hand. Usually temporary and resolves quickly. |
| Localized allergic reaction | Redness and swelling near the needle site, indicating a reaction to materials used for skin preparation or bandages. |
| Piercing of an artery | Accidental puncture of an artery instead of a vein, leading to a higher risk of bruising due to higher blood pressure. |
| Local inflammation of the vein (Phlebitis) | Tenderness and redness in the vein area, typically appearing days after donation. |
| Cellulitis | Skin infection causing redness, swelling, pain, and warmth, usually developing 1-2 days post-donation. Requires medical attention. |
| Nerve injury | Damage to nerves causing pain, pins and needles, and in rare cases, arm weakness. |
| Major blood vessel or tendon injury | Injury requiring potential surgery to correct, leading to prolonged discomfort or impaired function. Very rare. |
Allergic Reactions: Localized and Severe
Allergic reactions can occur due to materials used during donation, such as cleaning solutions or bandages.
Localized Allergic Reactions
These are more common and usually mild, presenting as:
- Redness
- Swelling
- Itching at the needle site
Severe Allergic Reactions
Severe allergic reactions are extremely rare but can be life-threatening. Symptoms require immediate emergency treatment and can include:
- Breathlessness
- Wheezing
- Facial swelling
- Difficulty swallowing
- Swollen tongue
Making an Informed Decision about Plasma Donation
While this article outlines potential reasons why someone might be hesitant to donate plasma, it’s important to remember that serious complications are rare. Blood donation centers take extensive precautions to minimize risks and ensure donor safety.
Understanding these potential side effects and risks is not meant to discourage donation but rather to empower you to make an informed decision. If you have concerns, discuss them with your doctor or the donation center staff. For most healthy individuals, the benefits of plasma donation, in terms of helping others, often outweigh the relatively low risks involved.
