Major updates to blood donation guidelines officially take effect across Brazil today, bringing significant changes to eligibility criteria. Established by the Ministry of Health, the modernized framework aims to balance donor safety with the urgent need to keep blood banks stocked by easing restrictions in several common scenarios.

## What Changed for Tattoos and Cosmetics

One of the most notable adjustments involves tattoos, piercings, and aesthetic procedures. Under the updated regulations, candidates who get a tattoo, permanent makeup, acupuncture, or procedures like botox and micro-needling face a reduced wait time of just seven days—provided the procedure's safety conditions can be verified. If the safety cannot be confirmed, a four-month deferral still applies.

For body piercings, restrictions remain in place as long as the jewelry is worn due to infection risks. Donors must wait four months after removing the piercing before they can safely give blood.

## Clearer Rules for Medications and Ozempic

The updated guidelines also address popular injectable medications, specifically GLP-1 receptor agonists like semaglutide, marketed under brands such as Ozempic.

Simply using the medication does not automatically disqualify a donor. Instead, a strict four-month deferral applies only to individuals who share injection devices. Medical professionals will evaluate all drug usage and underlying health conditions during the routine pre-donation screening.

## Expanding Access for Older Donors

While the general age requirement remains between 16 and 69 years old—with first-time donors capped just under 60—the new policy introduces an important exception. Regular, repeat blood donors are now permitted to continue donating past their 70th birthday, subject to a medical evaluation by hemotherapy services.

Other notable updates include a four-month wait period following endoscopic procedures or unauthorized anabolic steroid use, alongside refined risk windows for malaria exposure and travel. Despite the updated timelines, the foundational safety requirements remain unchanged: donors must weigh at least 50 kg and pass a rigorous individual clinical screening to protect both themselves and blood recipients.
