Medications and Vaccinations

The majority of medications will not prohibit you from donating, but some require a waiting period before becoming eligible to donate. These include certain medications for psoriasis, severe acne, hair loss, rheumatoid arthritis, HIV PrEP, and blood thinners.

Antibiotics taken for an active infection must be completed prior to your donation.

Aspirin must be avoided for at least 48 hours prior to your platelet donation; other non-aspirin pain relievers are acceptable.

If you received the COVID-19 vaccine, you must wait 24 hours before donating. Most other vaccinations do not require a waiting period as long as they were taken prophylactically (pre-exposure).

Some chronic illnesses, such as heart disease, asthma or diabetes, are acceptable as long as they are well-controlled with no restrictions.
