Donating plasma is a safe and generous way to help others, but it can have some side effects. The most common side effects are dehydration and fatigue, but these are usually mild and short-lived. Less commonly, donating plasma can cause dizziness, fainting, and lightheadedness due to a temporary electrolyte imbalance. More rarely, donating plasma can lead to more serious side effects such as arterial puncture, severe reactions to citrate, or even medical events such as a heart attack or stroke. Muscle cramps and soreness in the legs have also been reported by some donors, which could be related to dehydration, electrolyte imbalance, or iron deficiency. While donating plasma is generally safe, it is important to be aware of these potential side effects and seek medical advice if any symptoms persist or become concerning.

What You'll Learn
Dehydration and fatigue
To prevent dehydration, it is important to drink plenty of fluids before and after donating plasma. Some people recommend getting 3-4 litres of water the day before donating, as well as consuming sodium, magnesium, and potassium to stay hydrated. Eating foods with a high water content, such as soup, ice cream, jelly, and fruits like melon, can also help prevent dehydration.
Fatigue after plasma donation is often caused by low levels of nutrients and salts in the body. Plasma is rich in these substances, so losing some of them through donation can lead to fatigue. Fatigue can also be a symptom of dehydration, as the body's tissues do not have enough fluids to function optimally.
While dehydration and fatigue are usually mild and can be easily managed, severe dehydration can be a serious medical condition that requires urgent attention. Symptoms of severe dehydration include a rapid heart rate, sunken eyes or cheeks, extreme thirst, dark-colored urine, confusion, and fever. If you experience any of these symptoms after donating plasma, it is important to seek medical advice.

Arterial puncture
An arterial puncture is a rare complication that can occur when a needle is inserted into an artery instead of a vein. This can happen during a plasma donation when a technician misses the intended vein and accidentally hits an artery. Arteries have higher blood pressure than veins, so a puncture can cause bleeding into the arm tissues surrounding the puncture site. Signs of an arterial puncture include faster blood flow and lighter-than-usual blood running through the tubes to the plasma collection machine. Additionally, the needle and tubes may appear to move or pulsate with the increased blood flow, and the donor may experience weak pain near their elbow.
In the event of an arterial puncture, the technician will immediately remove the needle and apply pressure to the needle insertion site for at least 10 minutes. It is recommended to go to the Accident and Emergency department at the nearest hospital, especially if there are any changes in symptoms. A bruise will likely appear after an arterial puncture, and it may look dramatic or appear away from the donation area, which can be worrying.
The radial, brachial, and femoral arteries are the preferred sites for arterial puncture, while irritated, edematous, inflamed, or infected sites should be avoided. The radial artery is the first choice due to its small size, requiring extensive skill in arterial blood sampling. Brachial and femoral arteries are less superficial and may be harder to locate.
Several complications can arise from arterial puncture, with hemorrhage or hematoma formation being the most common. The risk of hemorrhage or hematoma can be reduced by using the smallest gauge needle acceptable and applying prompt pressure to the puncture site for at least 10 minutes after the procedure. Thrombosis is another potential complication, more common at the radial artery, and it may lead to ischemia, gangrene, and distal embolization of a clot or plaque.

Citrate reaction
Donating plasma is generally a safe process, but it can cause some common and minor side effects. In rare cases, it can also lead to a serious condition called a "citrate reaction".
During plasma donation, a technician infuses an anticoagulant, such as citrate, into the blood collected in the plasma-separating machine before it is returned to the donor's body. This anticoagulant prevents blood clots from forming. While the plasma in the machine retains most of the citrate, a small amount of it enters the donor's bloodstream. Citrate binds together with a small number of calcium molecules for a short time. This effect is minor and temporary, and most people do not experience any side effects. However, a small number of donors may experience a "citrate reaction" due to the temporary loss of calcium.
A citrate reaction is a rare but serious side effect of plasma donation. It can cause symptoms such as chills, tingling of the lips or tongue, a metallic taste, muscle contractions or spasms, seizures, breathing difficulties, and disturbance of heart rhythm. In some cases, it can also lead to hypocalcemia, which requires immediate medical attention. Severe symptoms of a citrate reaction may include muscle contractions or spasms, seizures, breathing difficulties, and heart rhythm disturbances.
While rare, citrate reactions can be life-threatening and require emergency treatment. It is important for donors to be aware of the potential risks and to seek medical advice if they experience any unusual symptoms during or after donating plasma.
Some donors have reported experiencing leg soreness and cramps after donating plasma. While the exact cause of these symptoms is unclear, it could be related to dehydration, electrolyte imbalances, or iron deficiencies. Staying hydrated before and after donating plasma is important to help prevent these issues. Additionally, consuming a balanced diet rich in nutrients and electrolytes can help maintain adequate hydration levels and prevent muscle cramps.

Electrolyte imbalance
Donating plasma can lead to an electrolyte imbalance in the body. Plasma is composed of 92% water and is rich in nutrients and salts. These salts and nutrients are essential for the body to function properly and keep it alert. When plasma is collected, the body loses these nutrients and salts, which can cause an electrolyte imbalance.
An electrolyte imbalance can lead to dizziness, fainting, and lightheadedness. These symptoms are often experienced immediately after donation and can be easily remedied. Donation centers typically encourage donors to sit, rest, drink water, and eat a snack before leaving. Eating something sugary can help stop feelings of dizziness.
To prepare for a plasma donation and reduce the likelihood of an electrolyte imbalance, it is recommended to eat a meal rich in iron and protein. Staying hydrated before and after donating plasma is also important. Adults are advised to drink nine to thirteen cups of water daily and an additional two cups of water before their appointment.
Some people may experience leg cramps and soreness after donating plasma, which could be related to dehydration or an electrolyte imbalance. Ensuring adequate hydration and consuming fluids with electrolytes can help counteract these symptoms.
While rare, severe reactions to citrate, an anticoagulant used during plasma donation, can also cause muscle contractions or spasms. However, most people do not experience any side effects from citrate.

Iron deficiency
Donating plasma can lead to iron deficiency, as each donation removes a significant amount of iron from the body. This iron depletion can cause anemia and other health issues. To mitigate this, donors should ensure they are consuming an iron-rich diet and limiting plasma donations to twice a week.
Some donors report experiencing leg soreness and cramps after donating plasma. While the exact cause of these cramps is not always clear, some donors suspect that it could be related to iron deficiency or dehydration. One donor mentions that they drink Liquid IV and eat a lot of protein after donating to ensure their electrolytes stay balanced.
It is important to note that the chances of experiencing serious problems from donating plasma are usually small. However, discussing your medical history and concerns with the staff before donating plasma is crucial. Proper self-care and hydration before and after the donation process are also recommended.
