Can You Donate Blood If You Take Metformin?
Metformin (Fortamet, Glumetza) is a diabetic medicine that is taken orally. A person with diabetes can donate blood as long as they can control their diabetes with insulin or oral drugs.
Taking metformin can make you ineligible to donate blood if you have Type 2 diabetes. In addition, taking vaccinations and injections may make you ineligible to donate blood. The donor center should be able to confirm if your medication is compatible with donating blood. However, most medications will not affect whole blood donation. If you are taking metformin for Type 2 diabetes, you should talk to your doctor about the proper timing.
Type 2 diabetes patients can’t donate blood if they take metformin
People with type 2 diabetes can donate blood safely as long as their sugars are well controlled. Blood donated by people with type 2 diabetes with high blood glucose levels is often not able to store very well in the donor’s body. Blood donation is not possible while pregnant or while using insulin. People with Type 2 diabetes cannot donate blood if they are on any diabetes medications or have taken bovine-derived insulin since 1980. Patients who have been taking bovine-derived insulin can’t donate blood because of the risk of contracting variant CJD or mad cow disease.
People with Type 2 diabetes who wish to donate blood should bring an ID, a list of their medications, and a portable blood glucose monitor. Some Type 1 diabetics have reported raised blood glucose levels three to five days after giving blood. This is why it’s important to stay on a blood glucose watch list after donating blood.
While people with type 2 diabetes who are on metformin may not be able to donate blood, they should talk to their doctor to make sure that their condition does not interfere with their ability to donate blood. This way, they can find the best solution for their particular situation. Those with Type 2 diabetes may also be taking external insulin. However, the patient should be in good health if they are planning to donate blood. The American Red Cross’ guidelines for blood donations are not as strict as the UK’s.
People with Type 2 diabetes can donate blood once every 56 days, but some doctors may recommend a longer period. In addition to the length of time between blood donations, some doctors recommend a longer period to avoid blood glucose disruption. People with diabetes can donate blood through the American Red Cross as long as their hemoglobin A1c level is not too high or too low.
People with Type 2 diabetes can’t donate blood if they take a form of insulin or metformin. However, people who are on oral hypoglycemic drugs can donate blood. The medications listed here are generally safe for donors with type 1 diabetes. It’s important to ask your doctor before donating blood if you are taking insulin or metformin. Once your blood is tested, you can make arrangements for it to be transported to the hospital.
This is not a surprising finding, as the incidence of cancer among people with type 2 diabetes is far higher than the average in the general population.
Vaccines and injections make you ineligible to donate blood
Before donating blood, make sure you know if you are ineligible for any of the following vaccinations or injections: polio, measles, rubella, measles vaccine, mumps vaccination, hepatitis A or B, rabies vaccination, yellow fever, or typhoid vaccination. If you have received a vaccination for any of these, make sure to bring the vaccination card with you. There are some misconceptions about vaccinations and injections, however.
If you’re pregnant, you can donate blood after two weeks of delivering or terminating your pregnancy. It’s important to note that most medications are safe to take during donation. However, if you have recently received a vaccination such as chickenpox or MMR, you should wait four weeks before donating. Vaccines like Varivax and COVID-19, however, are not required for donors. You may need a booster.
Getting a vaccination can put you ineligible to donate blood, but there are some exceptions. For example, hepatitis B vaccinations can cause a temporary positive result for donors. Donors should wait 21 days after their hepatitis B vaccination before giving blood. Vaccines given during these 21 days should be negative. If you’re traveling internationally, don’t be alarmed if the test comes back positive. Blood centers can requalify donors who are falsely positive for this disease. However, they must follow strict protocols when requalifying donors.
Taking metformin before donating blood
Donating blood can be a very personal experience for people with diabetes, but if you follow the correct guidelines, you can still donate blood even while taking the oral diabetes medication metformin. If you are taking metformin, you should check with your physician before donating blood. Taking metformin can reduce the amount of plasma that you can donate. Plasma is a crucial part of blood and contains many important proteins and antibodies for immunity and clotting. Before donating blood, make sure you understand the donation requirements for your specific facility.
If you are diabetic, you should not donate blood if your A1c level is higher than nine percent. Instead, you should speak with your doctor and get clearance from your health insurance company. Blood with too much sugar doesn’t store well. Lastly, don’t donate blood if you take insulin made from bovine sources. This medication has been linked to variant CJD, otherwise known as mad cow disease.
You should consult your doctor if you are planning to donate blood while taking metformin. Before you donate blood, you should monitor your blood sugar levels and re-nourish your body. Make sure to increase your fluid intake and eat foods high in iron. If you are planning on traveling to a different country, check the eligibility requirements in your local area. If you feel sick and can’t donate blood, you can reschedule your appointment.
Taking metformin before donation may lower your A1C and HbA1c levels. This may be a false negative because metformin causes red blood cell turnover, and it is important to follow a proper diet before donating blood. A good rule of thumb is to donate your blood within eight hours of the first dose. Your blood glucose will likely be higher than it will be on the day you donate.
