Can You Donate Blood with High Blood Pressure?
Quick Answer
Yes, you can donate blood with high blood pressure (hypertension) as long as your reading on the day of your visit is below 180/100 mmHg. Blood pressure medications are generally acceptable and do not disqualify you from donating.
High blood pressure is among the most common conditions donors carry into the center, and most people with hypertension donate without issue. Staff check your blood pressure as part of every standard pre-donation health screening. The acceptable range is systolic below 180 mmHg and diastolic below 100 mmHg. If you fall within those limits, you can donate regardless of whether you take medication to achieve them.
Who Is Eligible? The Full Picture
Common blood pressure medications — beta blockers, ACE inhibitors, ARBs, calcium channel blockers, and thiazide diuretics — do not disqualify you. What matters is your reading at the time of the visit, not your diagnosis. Bring a list of your medications to help the screener work through any questions quickly.
What to Expect at Your Appointment
If your reading is over the limit when you arrive, staff will defer your donation for that day and suggest rescheduling. If your readings are borderline, try arriving well-rested, avoiding caffeine for a few hours beforehand, and sitting quietly in the waiting area for 5–10 minutes before your screening. White-coat anxiety can temporarily elevate numbers — a few minutes of calm breathing can make a real difference.
