Antihistamines (allergy tablets) and blood donation

Yes, you can donate. Yes, cetirizine, levocetirizine, fexofenadine and montelukast are not deferrals. ## The short answer Allergy medicines do not affect blood safety or the donation process. Only sedation-heavy old formulas matter for comfort, choose a clear-headed day. ## At the screening desk Tell the staff: Tablet names. That conversation is confidential and takes a minute, it exists so the medical officer can clear you safely on the day. Everyone meets the same basics: age 18,65, weight 50 kg+, haemoglobin on target, feeling well today. Men donate every 3 months, women every 4, the rest rules, simply. Not sure about your case? Try the Can I donate? checker or read who can donate and the deferral list in plain words. Still weighing it? Is blood donation safe? and the honest side-effects list are straight answers, not brochure talk. ## The one line that matters The medical officer at the centre makes the final call on the day, with your name, your file and your actual reading in front of them.
